How Much Precision Can Be Achieved In PEEK Machining?

September 04, 2024

The accuracy of PEEK processing depends specifically on the processing method, processing conditions and the needs of the application scenario. In injection molding, high-precision injection processing can be achieved by optimizing the mold design, improving the performance of the injection molding machine and controlling the melt temperature. In machining, selecting appropriate tool materials and cutting parameters, and utilizing high-precision CNC machine tools for processing, high-precision PEEK products can also be obtained. For specific application scenarios under the demand for high-precision processing, but also need to be combined with specific process requirements and equipment conditions for comprehensive consideration and optimization.

PEEK processing accuracy in injection molding process

In the injection molding process, the processing accuracy of PEEK is affected by a variety of factors, including mold design, injection molding machine performance, melt temperature control, injection pressure and speed. Generally speaking, the injection molding dimensional accuracy of PEEK products can reach about 0.1mm. This requires highly accurate mold design, and the injection molding machine needs to have a stable heating system and precise control system to ensure that the melt maintains good fluidity at a constant high temperature (about 385°C), while avoiding degradation caused by overheating or insufficient fluidity caused by underheating.

PEEK machining accuracy in machining

In addition to injection molding, PEEK is also often processed by mechanical machining such as turning, milling, drilling, etc. In these processes, the machining accuracy of PEEK is also affected by machine tool accuracy, tool selection, and cutting parameters. In these processes, the machining accuracy of PEEK is also affected by machine accuracy, tool selection, cutting parameters and other factors. Due to the high hardness and wear resistance of PEEK material, the selection of appropriate tool material and cutting parameters is crucial. With high-precision CNC machine tools and optimized cutting strategies, the machining accuracy of PEEK can reach a very high level.

Different application areas have different requirements for the machining accuracy of PEEK. For example, in the medical field, PEEK is often used to make surgical instruments and so on because of its excellent biocompatibility and mechanical properties. The machining accuracy of these products is directly related to patient safety and surgical results, and therefore requires extremely high machining accuracy and surface quality. In the semiconductor industry, the machining accuracy of PEEK components is directly related to the stability and productivity of the equipment, which also requires high machining accuracy and dimensional stability.
