Firstly, under the premise of aluminum, the following aspects need to be considered
1、 Force Majeure
Stability of machine tool itself
If it is not a new machine tool or the machine tool has been processed a lot without debugging, the size error caused by the machine itself will appear. The machine tool itself causes the following errors:
China CNC machine tool processing machinery:
- a. Loose between servo motor and lead screw.
- b. Ball screw bearing or nut wear.
- c. The lubrication between the screw and the nut is insufficient.
Electrical
- a. Servo motor fault.
- b. There is dirt inside the grating ruler.
- c. Servo amplifier fault.
PMC recovery can be carried out for system parameters, so it is omitted.
2. Cooling deformation of workpiece after processing
This is basically unavoidable. Pay attention to the use of coolant when machining, and pay attention to the deformation of the workpiece after cooling when measuring in place.
