What errors are present in CNC lathe processing?

For CNC machining center , CNC lathe processing is a relatively complex process, which can be very accurate and will have some errors. Therefore, in our understanding of the process of CNC lathe processing, error is also the key to our CNC lathe processing. .

CNC lathe machining has high degree of automation, good accuracy and very high working efficiency. However, some errors are inevitable in CNC lathe machining, so we must understand the existence of these errors.

Error 1: Error in processing principle

The principle error of CNC lathe machining refers to the error caused by the use of an approximate processing motion mode or an approximate tool profile. Since there is an error in principle, it is called a principle error. This processing method is still feasible if the principle error does not exceed the allowable range.

Error 2: Machine tool geometric error

In use, the manufacturing errors, installation errors and wear of the machine tool directly affect the machining accuracy of the workpiece. These errors are mainly the rotational motion error of the machine tool spindle, the linear motion error of the machine tool guide rail and the machine tool transmission chain error.

Error 3: Tool manufacturing error and wear

Manufacturing errors, installation errors and wear during use of CNC lathe machining tools will affect the machining accuracy of the workpiece. During the cutting process, the cutting edge and cutting surface of the tool produce strong friction with the workpiece and chips, causing tool wear. After the tool wear reaches a certain value, the surface roughness value of the workpiece increases, the color and shape of the chips change, and it is accompanied by vibration. Tool wear during cutting directly affects cutting productivity, processing quality and cost.

Error 4: Fixture Error

CNC lathe machining fixture errors include positioning errors, fixture errors, fixture installation errors and tool errors. The error is mainly related to the machining and assembly accuracy of the fixture. The machining accuracy of CNC machine tools cannot be perfect, as long as the error is controlled within a certain range, it is meaningless. Processing errors and tool wear.

At present, CNC machining centers and CNC turning, milling and grinding are widely used in the mechanical processing industry. For friends or beginners who purchase machine tools, they cannot professionally judge the errors in CNC.
