Factors Affecting The Dimensional Accuracy Of CNC Machining 2

Apr. 29, 2019 | 11:39:15

As an Aluminum Alloy Parts Die Casting Supplier, we continue to analyze the factors that affect the dimensional accuracy of CNC machining.

Second, irresistible factors:

1. Cooling deformation after workpiece processing

This is basically unavoidable. Pay attention to the use of coolant during processing and pay attention to the deformation of the workpiece after cooling.

2. The stability of the machine itself

If it is not a new machine tool or the machine tool has undergone a lot of machining without debugging, the dimensional error caused by the machine itself may occur. There are several factors that cause the machine tool itself to have errors:

Mechanical aspects:

a. Loose between the servo motor and the lead screw

b. Ball screw bearing or nut wear

c. Insufficient lubrication between the screw and the nut

Electrical aspects:

a. Servo motor failure

b. There is dirt inside the grating scale

c. Servo amplifier failure

PMC recovery is possible in terms of system parameters, so it is omitted.
