What errors exist in CNC lathe machining?

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

CNC CNC lathes have a high degree of automation, good precision and high work efficiency, but there will inevitably be some errors in CNC CNC lathe processing, so we The existence of these errors must be understood.

Error 1: Error in machining principle

The principle error of CNC lathe machining refers to the error caused by the use of an approximate machining motion mode or an approximate tool profile. error, so it is called the principle error. In the case that the principle error does not exceed the allowable range, the processing method is still feasible.

Error 2: Machine tool geometric error

In use, the manufacturing error, installation error and wear of the machine tool directly affect the machining accuracy of the workpiece. These errors are mainly the rotary 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

The manufacturing error, installation error and wear of the CNC lathe machining tool will all Affect the machining accuracy of the workpiece. During the cutting process, the cutting edge and face of the tool generate 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, and the color and shape of the chips change, accompanied by vibration. Tool wear during cutting directly affects cutting productivity, machining quality and cost.

Error 4: Fixture error

CNC CNC lathe machining fixture error includes positioning error, fixture error, fixture installation error and tool error. 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. Machining errors and tool wear.

At present, CNC machining centers and CNC turning, milling and grinding are widely used in the machining industry. It is impossible to professionally judge the errors of CNC. Pay attention to Dongguan CNC CNC lathe processing or Dongguan CNC machining center - YIFENG METAL Technology to learn more about CNC CNC lathe processing.
