Parts in the process of CNC Machining,When the amount of turning and milling is large,The workpiece will be deformed.According to our Machining experience,Metal Machining deformation is small,plastic machining deformation is large.We have taken some technical measures to prevent deformation.
1,Will be rough machining and finishing machining separately, and the interval of 24 hours.So that after the rough machining of the natural recovery.
2,Reduce the impact of clamping force on the workpiece.In the machining technology to take the following measures to reduce the impact of clamping force
A, The machining position of the machined parts is chosen to improve the deformation of the thin-walled parts under the clamping force in the parts with strong force and thickness.
B, Change the direction of the machining force of the machined part and change the radial to axial.
C, Work on the workpiece to thread, with screws to fix the workpiece.
3, Reduce the impact of milling force on deformation during machining.
A,Use sharp machining tools to reduce the impact of milling on workpieces.
B, Finishing machining takes a smaller amount of cutting and reduces the deformation caused by the cutting force of the workpiece.
C, Inside and outside the surface at the same time processing, so that cutting force off.
