Delrin performs exceptionally well in CNC milling due to its high mechanical strength, low coefficient of friction and excellent dimensional stability. High-precision processing can be achieved by using sharp carbide tools and maintaining an appropriate cutting speed and feed rate. During the processing, attention should be paid to temperature control to avoid deformation of the CNC machining delrin parts due to overheating of the material.The adoption of gentle clamping methods and effective chip removal measures can further improve the processing quality.
►Key points of CNC milling process
Single-edge or single-helical milling cutters: High chip removal efficiency, reduced heat accumulation, and prevention of melt adhesive sticking to the cutter
High-speed steel (HSS) or coated cemented carbide are both acceptable; Choosing the latter can lead to a longer lifespan and a finer surface.
Small relief Angle (< 5°), large rake Angle (10-15°), which is conducive to cutting in and chip removal in CNC machining.
