What factors may cause parts to deform? Because a variety of CNC machining mold deviation or other production processing staff operating error is very easy to lead to parts deformation. This problem is easy to deal with. The first person must be clear about the actual reason for the deformation and then release to solve it. Therefore, in the whole process of CNC machining is very easy to cause parts deformation of the key elements are what?
Deformation caused by clamping of a part
In CNC machining process, when the parts with a good number of azimuths of the clamping force effect, to consider the order of the clamping force, for the parts and support point contact clamping force should be the first effect, and not easy to be very large, for the balance of the cutting speed of the key clamping force, should be effective in the end.
The second is to expand the total area of contact between parts and fixture or radial clamping force. Improving the stiffness of parts is a reasonable way to deal with clamping deformation, but because of the appearance and structural characteristics of thick-walled parts, they have low stiffness. So under the effect of clamping force, it will cause deformation.
