What are the basic criteria for CNC machining of precision parts?
CNC machining center is a high-efficiency automatic machine tool composed of mechanical equipment and numerical control system for processing complex parts.Its main purpose is to process some complex parts,for different products,machining tools,parameters,etc.Is it different,then what are the basic criteria for CNC machining of precision parts?
1,the benchmark first
That is,the reference surface is first processed,and the surface of the part as the positioning reference should be processed first in the machining process,so as to provide a fine reference for the processing of the subsequent process as soon as possible.
2.Differentiating the processing stage
The precision CNC machining quality request has a high appearance,which distinguishes the machining stage and can be generally divided into three stages:roughing,semi-finishing and finishing.The first is to ensure the processing quality;to facilitate the scientific use of equipment;to facilitate the organization of heat treatment processes;and to easily find the shortcomings of the blank.
3,the first back hole
For parts such as cabinets,brackets,and connecting rods,the plane-finished holes should be machined first.This makes it possible to position the holes in a plane,ensuring the azimuth accuracy of the planes and holes,and facilitating the processing of the holes in the plane.
4,finishing processing
The primary appearance of finishing,such as grinding,honing,fine grinding,rolling,etc.,should be placed at the end of the process road.The general guidelines for the development of fine CNC machining roads and the preparation of precision CNC machining procedures can be roughly divided into two parts.The first is to formulate the process road for part processing,and then determine the process scale,equipment and process equipment,cutting standards,and working hours quota for each process.
The above is the basic criteria for the CNC machining precision parts summarized by Jiexiang CNC Machining Center.The correct operation of the CNC machining center will not be bad.Therefore,we must master some basic guidelines for Used in CNC machining to get a better quality finished product.
