Process performance of CNC machining
January 29, 2023
CNC machining is a thin-walled part that is easy to deform. When clamping the workpiece, the pressure plate should be pressed at the part with good rigidity of the workpiece, and the distribution should be as uniform as possible to ensure the reliability of clamping.
When the CNC machined the cavity, the positioning and clamping of the parts can make the workpieces quickly and correctly clamped on the machine tool, and it is not necessary to align one by one when machining a batch of workpieces. Therefore, the machining adopts a positioning method of one pin and two pins. A simple tooling is used as a positioning hole on the part, and the tooling uses a cylindrical pin and a flat pin as positioning elements.
CNC machining is conducive to the dimensional and shape accuracy of the parts; high-speed machining can obtain high surface quality, and the processing cycle is also greatly shortened. Therefore, in combination with the characteristics of such thin-walled disk parts, high-speed machining is used when finishing the cavity.
This procedure requires that the internal profile be machined according to the part structure diagram shown, and the clamping force should be appropriate to prevent damage to the workpiece or to cause unacceptable deformation of the workpiece. Its specific positioning and clamping. This clamping method fully conforms to the characteristics of the machining center, and the one-clamp can complete the machining of the cavity and all the holes. Moreover, this process also requires pre-processing the positioning holes required for finishing at the hole position.
