What factors are involved in machining accuracy?

The production of manufacturers is related to mechanical equipment. With the help of machinery, our workload, effect and speed are much faster. Although said to have the help of mechanical equipment, but in the face of the customer's product quality requirements are so high. Nature requires high precision in the processing process, such as precision mechanical parts processing.

Precision machine parts processing, in milling machine widely used digital program control contour systems, including a wide range of process capabilities, simple and reliable and inexpensive phase systems, these systems are used by many factories, especially for the control of large vertical surface precision machine parts processing.

Correct programming of control program is one of the main conditions to ensure the machining quality of precision machinery parts. For digital program-controlled phase system, the preparation of control program is carried out by the use of automatic program-controlled preparation system, and its quality level depends largely on the price of the preparation control program.

The other is the machining error caused by manual control of the equipment, including the accidental error and systematic error of the process system. System error plays an important role in all the machining errors, which will cause a series of NC process system errors for precision machine parts machining as a whole.

For example, clearance, its consequences as the machine tool transmission chain in the insensitive belt, but does not include the reverse transmission chain clearance; Amplification factor of unstable drive; Phase error on control program tape; The main form of periodic step instability of sensor feedback is phase instability.
