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 lathe has a high degree of automation, good precision and high work efficiency, but there will inevitably be some errors in CNC lathe processing, so We must understand the existence of these errors.
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 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 in use of CNC lathe machining tools, will 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, etc. . 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. For friends or beginners who purchase machine tools, It is not very professional to judge the errors existing in the numerical control. Follow CNC CNC lathe machining or CNC machining center - technology to learn more about CNC CNC lathe machining.
