Five-axis machining is a high-precision, high-efficiency machining technology, compared with the traditional three-axis machining, it has many important advantages. Let’s let 3d animation production companies explore the advantages of five-axis machining.

First of all, five-axis machining can complete complex parts in a single unit. Compared with three-axis machining, five-axis machining can realize the machining of more complex work surfaces without the need for multiple repositioning of the workpiece, thus reducing the waste of time and resources in the machining process. Five-axis machining can accurately excavate and trim the surface shape of the part, especially for parts with irregular shape or curved tilt, five-axis machining can ensure the high precision of the final product.

Secondly, five-axis linkage machining can be processed on multiple surfaces at the same time. The traditional three-axis processing can only process the “surface”, that is, a certain side of the workpiece, while the five-axis linkage processing can simultaneously process multiple faces, so as to achieve more processing effects in the same time period. This advantage makes the five-axis linkage machining very advantageous in the processing of complex parts, because it can efficiently process complex parts in a short time, improving production efficiency.

Third, five-axis machining has efficient and accurate control capabilities. Its control method and three-axis machining is different, combined with the quality control system, such as tracking system, real-time detection system, automatic calibration system, etc., five-axis linkage machining can adjust the processing quality in time to ensure the accuracy and quality of the product, so as to achieve more accurate and highly controlled process.

In addition, the processing accuracy of the five-axis linkage machining is higher, and the processing speed is higher, and the complex parts can be processed in a short time. This makes the five-axis linkage machining in a variety of industries required precision pa processingrts and complex surface parts processing has a very wide range of applications.

In summary, five-axis machining is one of the important technologies of modern CNC machining, it has many excellent characteristics and a wide range of application prospects, in aviation, aerospace, automotive, machinery, medical equipment and other fields have important applications.

Five-axis linkage machining is a relatively high-end technology in the field of CNC machine tool processing, and its main feature is that it can complete the processing of multiple planes under a single clamping, which greatly improves the processing efficiency and production accuracy. The following details the advantages of five-axis linkage processing.

1. A wide range of processing: five-axis linkage processing can be processed in X, Y, and Z at the same time, and can also be processed on the C axis (rotation axis) and A axis (tilt axis), making the processing range very wide, can complete a variety of complex shape parts processing.

2. High production efficiency: traditional machine tools need multiple clamping, adjustment and other processes to complete the processing of the workpiece, and five-axis linkage machine tools can achieve multiple plane processing through different angles in the case of a clamping, thus greatly shortening the processing time and improving production efficiency.

3. High machining accuracy: The five-axis linkage machining can realize 360-degree rotation and multi-angle tilt machining of the workpiece through the movement of each axis, thus making the machining accuracy higher, especially for the processing of special workpiece, very high machining accuracy can be achieved.

4. High quality of the workpiece: The five-axis linkage machining adopts high-speed tool speed, high-precision tool path control and high-stability machine tool structure, which can ensure the stability and good quality of the surface quality of the machined parts, and improve the quality of the workpiece and the overall processing effect to a certain extent.

5. Easy operation: five-axis linkage machining is generally controlled by numerical control system, the operation is relatively simple, as long as the master of numerical control programming technology, you can easily achieve a variety of complex parts processing, at the same time, the processing process does not require complex equipment and professionals, can reduce operating costs, improve work efficiency.

In short, as a high-end processing technology, five-axis linkage machining has the advantages of wide processing range, high production efficiency, high processing precision, high workpiece quality, easy operation, etc., and will be more and more applied in the future development.

These services not only cover traditional machining methods such as turning, milling, drilling, planing and grinding, but also include high-end technologies such as laser cutting and electric discharge machining. Enterprises can also provide customized five-axis CNC machining services according to customer needs, such as the processing of complex workpieces, difficult processing, and high process accuracy.

In general, Dongguan’s five-axis CNC machining enterprises have considerable advantages in processing technology and equipment. They can meet the processing needs of various complex parts and components, and are always committed to improving their own technology and service levels, helping customers improve production efficiency and reduce costs, and making important contributions to the development of manufacturing.

Five-axis CNC machining is a high-efficiency and high-precision machining method, which uses numerical control technology and five-axis three-dimensional tools, which can greatly improve the processing accuracy and work efficiency of parts. Five-axis CNC machining is widely used in precision machining, such as mold, aviation, aerospace, automotive, medical devices and electronic parts industries.

The advantages of Dongguan five-axis CNC machining are:

1. High-precision machining: five-axis CNC machining adopts numerical control technology, which can be processed according to the predetermined trajectory, which can not only process parts of various shapes and dimensions with high precision, but also ensure high-precision repeatability during processing.

2. High efficiency machining: five-axis CNC machining method does not require manual operation, which can greatly improve production efficiency. More parts can be machined in the same amount of time, thus increasing production efficiency.

3. More kinds of parts can be machined: five-axis CNC machining can process more complex curved parts, with stronger processing capacity. In addition, it can also process a variety of metal and non-metallic materials, such as titanium alloy, aluminum alloy, copper, iron, stainless steel and so on.

4. Reduce the number of parts: Through five-axis CNC machining, many parts can be combined together, thus reducing the number of parts and reducing costs.

5. Environmental protection and safety: five-axis CNC machining process does not require the use of chemicals and other toxic substances, will not have an impact on the environment, but also reduce the operational risk of workers.

When using five-axis CNC machining, it is important to note that:

1. Rational use of tools: for different workpiece materials and processing requirements, different tools need to be selected to obtain better processing results.

2. Keep the equipment clean: It is necessary to keep the equipment clean and in good condition, and maintain it frequently to ensure the normal operation of the equipment.

3. Reasonable setting of processing parameters: For different workpiece materials and processing requirements, it is necessary to set processing parameters reasonably to obtain the best processing effect.

In short, Dongguan five-axis CNC machining is a high-efficiency, high-precision processing method, which has been widely used in many manufacturing industries, and provides an effective means for the manufacturing and production of parts.

There are basically two types of five-axis CNC machining:

Trunnion type

When the trunnion type five-axis machine is operated, the A axis rotates around the x axis and the c axis rotates around the z axis. The rotating shaft is represented by the movement of the table. This type is more suitable for larger workloads as there is no need to compensate for the space taken up by the rotating handle.

Rotary type

Rotary five-axis machine, B axis rotates around the y axis, c axis rotates around the z axis. What makes it different is that the table is always level during the cutting process, which means it can support heavier parts. The rotating axis is represented by the rotating cutting arm.

What is the cost of five-axis CNC machining?

The cost depends on the project at hand and the number of parts being produced. In addition to the higher cost of purchasing a five-axis machine, five-axis CNC machining requires a more significant level of setup before starting production of a component. During pre-production, higher initial setup costs may reduce output or one-time costs compared to equivalent parts produced on a three-axis machine.

This is understandable because five-axis machines by their nature are more complex and dynamic than other types of CNC machines with fewer axes. Five-axis milling machines are also more time efficient because they can calibrate the finished part without any intervention. Often, only one operation is required to complete the workpiece, so downtime is greatly reduced. The requirements for fixtures are reduced, which mainly benefits more organic, complex parts.

Why are there fewer fixtures for five-axis CNC machining?

The range of motion the cutting head can achieve: The additional rotation axis means that these machines can reach five sides of a part. For example, if a geometrically complex part is needed for aerospace, a five-axis CNC machine would be the machine most capable of achieving this goal. This is due to its ability to reach complex angles and cut areas that are difficult to get, such as composite curves.

Advantages of five-axis CNC machining, high quality finish

Thanks to the advanced features of the five-axis cutting tool, a higher quality finish can be achieved because the cutting tool can be shorter on the five-axis CNC machine. This reduces the vibration of the tool and, therefore, reduces the chance of flutter marks and ensures the surface finish of the final part. The need for time-consuming and expensive hand machining can be almost completely eliminated, as five-axis machines can closely follow geometric contours that are traditionally difficult to machine.

More complex shapes can be made

Five-axis CNC machining can produce very complex geometric shapes. For example, in the past, machining castings and parts containing many different characteristics required a lot of assembly to machine and complete the desired shape. However, in most cases, with only one fixture, five-axis machining can complete the precise requirements of a workpiece.

To learn more about five-axis CNC machining and how it can benefit your business, please contact us. With many years of expertise, we will give you a detailed and concise quote about your needs within 24 hours.

1. Five-axis linkage machine tool with double turntable structure

The table set on the bed can be rotated around the X axis, defined as the A axis, the general operating range of the A axis +30° to 120°. There is no rotary table in the middle of the table rotating around the Z axis, defined as the C axis, the C axis can generally be 360° rotation. In this way, through the combination of the A axis and the C axis, in addition to the bottom surface of the workpiece fixed on the workbench, the remaining five faces can be processed by the vertical spindle. The small index value of the A axis and the C axis is generally 0.001°, which can be subdivided into any Angle to process the inclined plane and the inclined hole. A axis and C axis such as X, Y, Z three linear axis to achieve linkage, you can add a complex space surface, of course, this requires the support of numerical control system, servo system and software. The advantage of this setting is that the structure of the spindle is relatively simple, the rigidity of the spindle is very good, and the manufacturing cost is relatively low. However, the general work table can not be designed too large, the load bearing is small, especially when the A-axis rotation is equal to 90°, the workpiece cutting will bring A large cutting moment to the table.

2. Five-axis linkage machine tool with rotating table and swinging head structure

Since the turntable can be A axis, B axis or C axis, the swing head is the same, can be respectively A axis, B axis or C axis, so the turntable plus the swing head structure of the five-axis linkage machine can have a variety of different combinations to adapt to different processing objects. The advantage of this setting is that the spindle machining is very flexible, and the table can also be designed to be very large. The huge fuselage of the passenger plane and the huge engine casing can be machined in this kind of processing. This design has another major advantage: When using a spherical milling cutter to process surfaces, when the center of the tool is perpendicular to the machining surface, because the apex linear speed of the spherical milling cutter is zero, the surface quality of the workpiece cut out by the vertex will be very poor, and the design of the spindle rotation makes the spindle turn an Angle relative to the workpiece, so that the spherical milling cutter avoids the vertex cutting, ensuring a certain linear speed, which can improve the surface processing quality.

This structure is very suitable for mold high-precision surface machining, but it is also difficult to do rotary machining center. In order to achieve high precision of rotation, the rotation shaft is also configured with circular grating scale feedback, and the indexing degree is within a few seconds, of course, the rotation structure of this kind of spindle is more complex, and the manufacturing cost is higher.

3. Five-axis linkage machine tool with double swing head structure

Because of the structure itself, there is generally an electric spindle with a loose broach structure in the middle of the swing head, so the size of the double swing head itself is not easy to make small, generally in 400 to 500mm, plus the need for the range of activity of the double swing head, so the processing range of the five-axis linkage machine tool of the double swing head structure should not be too small, but the larger the better, generally gantry or moving beam gantry, The width of the gantry is better than 2000 to 3000mm.

At present, the more advanced double-swing head type five-axis linkage machine tool swing head structure generally adopts “zero transmission” technology of torque motor “zero transmission” technology in the rotary shaft application is to solve its transmission chain stiffness and accuracy of the ideal technical route. With the development of technology, the manufacturing cost of the twisted motor has been greatly reduced, and the market price has also fallen, and this process will promote the manufacturing technology of the five-axis machine tool to be greatly advanced.

As shown in Figure a), when the cutting tool moves to the top or the edge of the workpiece, the cutting state gradually deteriorates. In order to maintain the optimal cutting state, a rotating table is required. If you want to complete the machining of irregular planes, you also need to rotate the table several times in different directions.

As shown in Figure b) tool tip position diagram, the deflection tool of the five-axis machine tool can avoid the cutting speed of the ball end milling cutter at the center point of 0, and obtain better surface quality.

(2) The production chain and production cycle are shortened

Five-axis CNC machine tool through the spindle head tilt for side wall machining, do not need multiple parts clamping, effectively reduce the positioning error, improve the processing accuracy, and shorten the manufacturing chain. In aerospace, automotive and other fields, with high flexibility, high precision, high integration and complete processing capabilities can well solve the problem of precision and cycle of complex parts processing in the process of new product research and development, greatly shorten the research and development cycle and improve the success rate of new products.

(3) Efficiency improvement and interference elimination

For impeller, blade and mold steep side wall machining, the three-axis CNC machine tool can not meet the processing requirements, the five-axis CNC machine tool can be controlled by the tool shaft space attitude Angle to complete such processing content. At the same time, it can realize short tool processing deep cavity, effectively improve the rigidity of the system, reduce the number of tools, avoid special tools, expand the use of general tools, thus reducing the production cost.

For some inclined surfaces, five-axis CNC machining can use the tool side edge to finish the side wall cutting, so as to improve the machining efficiency and surface quality. The three-axis CNC machining relies on the stratified cutting of the tool and subsequent grinding to approximate the inclination plane.

Three axis machining method:

The three-axis machining is carried out by the linear feed axes X, Y and Z. Machining characteristics: The direction of the cutting tool remains unchanged during movement along the entire cutting path. The cutting state of the tip cannot be perfect in real time.

3+2 processing methods:

The two rotating axes first fix the cutting tool in an inclined position, and then the feed axes X, Y, and Z are processed. This machine tool is also called positioning five-axis machine tool. A rotating working plane in a space can be defined by 3+2 axis machine machining, such as a rotary head or a rotary table. On this working plane, 2D or 3D machining operations can be programmed.

Processing characteristics: The rotating shaft is always rotated to the position of the machining plane perpendicular to the tool axis for processing, and the processing plane is kept fixed during processing.

5 axis machining method:

Five-axis CNC machining by the feed axis X, Y, Z and around X, Y, Z rotation axis A, B, C in any of the linear interpolation motion.

Machining features: The direction of the tool can be optimized during the movement along the entire path, while the linear movement of the tool is carried out. In this way, the optimal cutting condition is maintained along the entire path

How to show the advantages of the five-axis machine, here is an example of processing 28 parts at the same time. Through the design of the turntable and the fixture, and in the five-axis machining program, the three machining surfaces of the part are combined into one machining program to achieve the purpose of reducing the cycle time.

The turntable can expand the original processing space through accurate positioning. The carefully designed fixture can not only improve the efficiency of processing, but also reduce the idle of the machine, and the operator can also draw out from it.

For example, the first three sides of the parts such as the image below, if use the clamp of the vice, each part will need 264 seconds (the time is not a).

By designing a more compact fixture and making full use of the processing space provided by the turntable, the opportunity to process 28 parts at once is available.

In the production of the fixture, an aluminum alloy with a size of 114*114*550mm is selected as the matrix, the positioning pin is selected as the positioning, and the compression fixture occupying less processing space is selected for faster clamping.

Then milling the four faces of the matrix, machining a positioning pin hole for each part, 2 slots for avoiding the locking fixture, and 2 thread holes for locking, this is all the production steps.

The whole set of fixture consists of 28 positioning pins, 56 positioning locking blocks (reusable), 56 screws and wrenches. Such fixture design can shorten the original processing time of 264 seconds to 202 seconds (regardless of clamping time). This means that the processing time has been reduced by 23.5%.

Not only that, because the processing program has combined the three processing surfaces of the parts in one processing program, so that the cycle time of a single program has become 95 minutes, during which the machine has been maintained processing, without waiting for the operator’s frequent clamping, which will greatly reduce the labor intensity of the operator.

In this issue, we will take the industry-leading Makino five-axis machining center as an example to introduce what main factors need to be considered in choosing a five-axis machining center.

01 Structure determines device performance

The five-axis machining center has a variety of structures, and the structural design of the machine tool determines the performance of the equipment from the basis, which determines the rigidity, processing accuracy, stability, operability and so on

The following aspects should be considered:

1) Linear axes do not merge when moving

2) The equipment with short cutting circuit has good rigidity

3) Whether the tilt rotation shaft is a DD motor

4) Whether it is 5-axis linkage

5) 5-axis proximity

Makino’s D200Z/D800Z/a500Z series five-axis machining center adopts A “Z” type high-rigidity table structure, as shown in the following figure, the table does not need to be supported at both ends, large diameter inclined bearings, and the workpiece center of gravity B is in A. Compared with the traditional single support structure, the bending amount d is very small, and the moment arm L is shorter.

This inclined shaft structure can be achieved with the high precision processing of the 3 axis processing center. Even if loading and rotating heavy industry, the bending quantity of the workbench can also be controlled at the minimum, and high rigid bearings and direct driving motors can also realize the smooth rotation of small, high precision. There is also an excellent space approach.

The tilted axis structure has excellent spatial proximity

02 Tilt rotation axis accuracy

The machining accuracy of the machine tool is directly affected by the precision of the rotating axis, and the actual influence of the tilting rotary axis accuracy on the machining accuracy is understood by the Maino D800Z machine tool.

1°= 60 ‘1°= 60 “1°=3600”

The minimum resolution of the B/C axis of the D800Z machine tool is 0.0001 degree, that is, 0.36 “, and the positioning accuracy is ±3 “. Through the calculation diagram below, we can know the accuracy error generated.

03 Interference collision prevention

Interference avoidance is a problem that can not be ignored in 5-axis machining. In addition to the use of computer-side software interference inspection, Makino’s 5-axis machining center is equipped with online real-time simulation CSG function, which can prevent interference even in manual mode.

Online real-time simulation of the CSG function allows possible tooling errors or tool length setting errors to be checked prior to machining in order to minimize emergency stops in operation. In operation, the position information can be read based on the data adjusted in advance, as well as the coordinates and offset values in the CNC control device, and the possibility of interference can be predicted. Once the machine stops running, the condition screen can be displayed in real time, and the predicted involved parts and shaft direction of action can be confirmed.

04 Rotation center correction

Due to changes in the rotation center caused by changes in environment and temperature, it will affect the accuracy of five-axis machining, and it should be able to be automatically corrected by the probe, 3-axis/indexing / 5-axis machining accuracy verification processing, and tool joint error < ±4μm.

05 Linkage accuracy

The linkage accuracy of five-axis machining center is the embodiment of multi-factor results. Taking Makino D200Z as an example, the processing cases are listed to provide linkage accuracy reference.

Processing equipment: D200ZCAM: FFCAM Workpiece material: NAK80(40HRC) Workpiece size: 140x140x35mm Cavity: clear Angle R0.22mm, depth 20mm Processing time: 1H35min/pocket tool: 7 kinds of 6

Linkage accuracy: position accuracy ±2μm, shape accuracy ±3μm

06 Process Support

The processing technology of the five-axis machining center determines whether the performance of the equipment can be maximized. For example, the special-shaped tool can greatly improve the processing efficiency.

Processing case: Efficiency increased by 6 times!

Material: YXR33(58HRC) Shape and size: as shown below, depth 30mm, drawing Angle 2°, clearing Angle R3mm
