General Principle of Precision Machining

PTJ is a CNC processing manufacturer and a manufacturer and supplier of precision mechanical parts. Here we talk about some basic principles of precision machining:

processing base level

cnc  machining parts , because the placement of surface should be processed out firstly, so can provide a fine benchmark for the follow-up process as soon as possible. This is known as “the baseline first”

The division of digesting stage

 Surface require high quality processing demand, is divided into roughing, semi-finishing and finishing three stages generally. This is mainly  ensure cnc machining  quality, and conducive to the use of equipment. This is easy to set up heat treatment process and facilitate to find out rough defects.

 Intended for the box, mount, connecting fishing rod and other parts, you should highly processed plane first of all, then procedure the hole. Not only does this can assure the position finely-detailed of the airplane and pin, but likewise bring comfort for refinement hole over the plane.

some. Finish the method. Grinding, Focusing, rolling digesting should be placed in the final stage of the process. Surface smoothness after digesting should above Ra0. 8um, a slight crash will be damaged surface. After finishing process, we must use velvet to get protection, hand or other objects directly contact is usually not allowed completely, this is to avoid damage because of process between transportation and installation.
