Precision (Precision)-This section mainly introduces the precision of mechanical processing, that is, the processing accuracy is in the range of 0.004-0.01mm.

In the past 10 years, the machining accuracy of ordinary CNC machines has increased from 10 m to 5 m, and the precision machining centers have increased from 3 to 5 m to 1 to 1.5 m, and the ultra-precision machining accuracy has begun to enter the nano-level (0.01 m).

Open-loop control: control mode without position feedback device. Processing accuracy is generally around 0.02-0.05mm accuracy.

Semi-closed loop control: It refers to the angular displacement detection device is installed on the shaft of the open-loop control servo motor. The displacement of the moving parts is detected indirectly by detecting the rotation angle of the servo motor and fed back to the comparator of the numerical control device. The value controls the moving part. Processing accuracy is generally around 0.01-0.02mm accuracy.

Closed-loop control: It is a direct linear or rotary detection device at the corresponding position of the final moving part of the machine tool. The directly measured displacement or angular displacement value is fed back to the comparator of the numerical control device and compared with the input command displacement. The value controls the moving part, so that the moving part moves strictly according to the actual displacement. Processing accuracy is generally around 0.002-0.01mm.
