In the field of machining, different processing processes are selected for different material processing. Now the processing method of lower plastic nylon material is discussed. Nylon material belongs to plastic. When machining a hole less than 30mm in diameter, due to the narrow space in the hole and difficult heat dissipation, it is necessary to reduce the lathe speed to less than 300 rpm and cool it with cutting fluid; Slow and uniform drilling and timely chip removal; When the drill bit is about to penetrate through the hole, it needs to be more careful to reduce the drilling speed. The cutting fluid or cooling water must be sprayed evenly to the orifice position.
Secondly, when machining holes larger than 30mm in diameter with nylon materials, first sharpen the drill bit to facilitate processing and avoid damage to the workpiece; Reduce the lathe speed to less than 180 rpm. For holes larger than 55mm, the lathe speed can be reduced to about 60 rpm; Drill in slowly and at a uniform speed, remove chips in time and spray sufficient cutting fluid; When the bit is out of the hole, be careful of the withdrawal speed. When the lathe processes small diameter holes, the speed shall be less than 60 rpm; When drilling at a constant speed and low speed, the operator must stabilize the tailstock handle to prevent the drill bit from being quickly brought into the hole by the lathe, resulting in product cracking; The cutting fluid is sprayed evenly.
For nylon material excircle processing, it is best to use white steel tools instead of alloy tools. The tools should be kept sharp; The lathe speed shall not be less than 200 rpm; Proper feed speed can improve machining accuracy and surface finish.
The above is a brief discussion on the methods of CNC processing plastic nylon materials. Thank you for your attention.
