Techniques and Tools for PEEK CNC Machining
1. Optimal Tools for Machining PEEK
When it comes to machining PEEK, the right tools can make all the difference between a successful project and a costly setback. Standard tools often fall short due to PEEK’s hardness and resilience. To ensure precision and efficiency, you need to invest in high-quality, durable tools.
-
Carbide Tools: Carbide tools are renowned for their hardness and wear resistance. They maintain a sharp cutting edge even under the demanding conditions of PEEK machining. These tools are particularly effective for roughing operations where high material removal rates are required.
-
Diamond-Coated Tools: For finishing operations, diamond-coated tools are the gold standard. The diamond coating provides unparalleled hardness and thermal conductivity, ensuring minimal tool wear and excellent surface finishes. These tools are ideal for achieving the tight tolerances and smooth surfaces that PEEK components often require.
Imagine having the confidence that your tools will not only last longer but also deliver superior results with each pass. At RALLY, we understand the importance of using the right tools for the job, and we provide the expertise needed to select and utilize these optimal tools effectively.
2. Recommended Machining Parameters
Achieving the best results in PEEK CNC machining requires more than just the right tools; it also demands precise control over machining parameters.
-
Cutting Speeds: To minimize heat generation and prevent thermal expansion, it’s recommended to use lower cutting speeds, typically ranging from 50 to 150 meters per minute (m/min). Lower speeds help maintain tool integrity and ensure dimensional accuracy.
-
Feed Rates: Moderating the feed rate is crucial for achieving a balance between material removal and surface quality. A feed rate of 0.1 to 0.3 millimeters per revolution (mm/rev) is generally effective, providing a smooth finish without overloading the tool.
-
Coolant Usage: Effective cooling is essential to managing the heat generated during PEEK machining. Using a high-quality, water-soluble coolant helps dissipate heat and prevent thermal distortion. Applying coolant directly to the cutting zone ensures that both the tool and the workpiece remain at optimal temperatures.
-
Depth of Cut: Controlling the depth of cut is critical for preventing tool wear and ensuring consistent quality. For roughing, a depth of cut between 2 to 4 millimeters (mm) is typical, while finishing operations may require a more delicate touch, with depths of cut around 0.5 to 1 millimeter (mm).
