When shoe mold manufacturing enterprises are in the process of purchasing high - performance CNC milling machines, they need to pay close attention to several key performance indicators. Firstly, mechanical rigidity is of utmost importance. A CNC milling machine with high mechanical rigidity can withstand heavy cutting forces without significant deformation. For example, a well - designed machine may have a rigidity that allows it to maintain an accuracy deviation of less than ±0.01mm under a cutting force of 5000N.
Secondly, processing accuracy is another critical factor. High - precision machining is essential for creating detailed and accurate shoe molds. Modern CNC milling machines can achieve a positioning accuracy of up to ±0.005mm and a repeatability accuracy of ±0.003mm. This high level of accuracy ensures that the produced shoe molds meet the strict design requirements.
Multi - axis linkage ability is also a key consideration. With the development of shoe mold design, more complex shapes and contours are required. Machines with 4 - axis and 5 - axis rotation worktables can provide greater flexibility in machining. A 4 - axis CNC milling machine can perform circular interpolation and helical interpolation, which is suitable for machining some relatively complex shoe mold parts. While a 5 - axis CNC milling machine can achieve more complex multi - surface machining, greatly improving the design diversity and production efficiency of shoe molds.
4 - axis and 5 - axis CNC milling machines offer significant advantages in shoe mold manufacturing. The 4 - axis rotation worktable allows the workpiece to be rotated around one additional axis, enabling the machining of curved surfaces and complex geometries. This can reduce the number of setups and improve the overall production efficiency. For instance, it can reduce the machining time of a complex shoe mold part by up to 30% compared to a 3 - axis machine.
The 5 - axis CNC milling machine takes it a step further. With the ability to rotate around two additional axes, it can access any angle of the workpiece, making it possible to machine extremely complex shoe mold designs. It can reduce the need for multiple setups and re - clamping, which not only saves time but also improves the accuracy of the final product. Some tests have shown that 5 - axis machining can increase the surface finish quality of shoe molds by up to 20%.
Equipment stability is crucial for ensuring continuous production. A stable CNC milling machine can operate for long hours without breakdowns. For example, a high - quality machine may have a mean time between failures (MTBF) of more than 2000 hours. This long - term stability reduces production interruptions and maintenance costs.
Maintenance convenience is also an important factor. Machines with easy - to - access components and clear maintenance instructions can save a lot of time and effort. For example, some machines are designed with modular structures, which allow for quick replacement of worn - out parts.
High - quality after - sales service is essential for solving problems in a timely manner. A reliable manufacturer should provide 24/7 technical support, on - site maintenance services, and a comprehensive spare parts supply system. This ensures that any issues can be resolved quickly, minimizing the impact on production.
To avoid blind purchasing, a systematic evaluation framework is necessary. This framework should include a comprehensive assessment of the machine's performance, price, after - sales service, and compatibility with the existing production line. A table can be used to compare different models:
| Model | Mechanical Rigidity | Processing Accuracy | Multi - axis Linkage Ability | Stability | Maintenance Convenience | After - Sales Service |
|---|---|---|---|---|---|---|
| Model A | High | ±0.005mm | 4 - axis | Good | Easy | Excellent |
| Model B | Medium | ±0.01mm | 3 - axis | Average | Moderate | Good |
Some common selection mistakes include only focusing on price without considering performance, ignoring the machine's compatibility with the existing production line, and not evaluating the after - sales service.
When evaluating after - sales service, consider factors such as response time, on - site service availability, and spare parts supply.
