First of all, when nylon machining small holes smaller than 30mm, due to the narrow space in the small holes and difficult heat dissipation, the lathe must be operated to reduce the speed of the lathe to below 300 rpm and use cutting fluid to cool it; drill slowly and at a constant speed, and remove chips in time ; Through hole, when the drill bit is about to penetrate to the bottom of the hole, you need to be more careful, reduce the drilling speed, cutting fluid or cooling water, must be evenly sprayed to the position of the hole. 9 @ e% h7 j'^;}

Secondly, when nylon machining is used to process holes larger than 30mm, the drill must be sharpened first to facilitate processing and reduce the scrap rate; reduce the lathe speed to below 180 rpm, and for holes greater than 55mm, the lathe speed can be reduced to 60 R/min or so; drill in slowly and at a constant speed, remove chips in time, and spray sufficient cutting fluid; when the drill is out of the hole, be careful and reduce the drilling speed.

Then, when nylon mechanical processing is used for small hole reaming, the speed of the lathe should be less than 60 rpm; the drill is at a constant and low speed, and the operator must stabilize the tailstock handle to prevent the drill from being quickly brought into the hole by the lathe, resulting in products Cracking; cutting fluid spray evenly.

Finally, for nylon outer circle processing, white steel tools should be selected as processing tools, alloy tools should not be used, and the tools should be sharp; the lathe speed should not be less than 200 revolutions/min; appropriate feed speed can improve the processing accuracy and surface finish.
