Roughing rough cavities is mainly to remove large margins and lay a good foundation for subsequent finishing. Therefore, when processing cavities, choose low-cost general digital control CNC machining and milling machines. The process needs to be processed according to the part structure shown in the internal shape summary, arc corner is R5mm, the remaining fine finishing allowance is 1.5mm. And this process also needs to pre-finish the positioning holes required for finishing in the φ12mm hole position. The
2 High-speed machining of high-precision cavities is a production skill that has been used in recent years. In high-speed cutting, because the cutting force is small, the processing distortion of the part can be reduced, and it is more suitable for thin-walled parts, and the chips are removed in a short time. Most of the cutting heat is taken away by the chips and the workpiece is thermally deformed. Small, help to ensure the accuracy of the scale, shape; high-speed processing can obtain a higher surface quality, the processing cycle is also greatly shortened, so contact the characteristics of thin-walled disc type, high-speed machining when used in the finishing cavity.
3 Positioning hole processing The part finish machining uses the base hole φ6mm and φ12mm hole as the positioning hole, so it must be processed in place before finishing the cavity. The base hole φ6mm is cut into φ6H8 when it is φ301.5mm. The φ12mm hole is drilled and hinged to φ12H8 by digitally controlled CNC machining.
Positioning and clamping of parts during finishing cavity To enable workpieces to be installed on the machine quickly and accurately, and not to correct them one by one when processing a batch of workpieces, this process uses a two-pin positioning method. . The φ6mm and φ12mm holes already existing on the parts are used as the positioning holes to make a simple tooling. The tooling uses a cylindrical pin and a flat pin as positioning elements. Because the part is attributed to the thin-walled part, it is easily deformed. When clamping the workpiece, the pressure plate should be pressed on the part where the workpiece rigidity is good, distribution is as uniform as possible to ensure the reliability of the clamping, and the size of the clamping force should be appropriate. In order to prevent damage to the positioning of the workpiece or the workpiece does not allow deformation. Its detailed positioning and mounting. This clamping method fully conforms to the characteristics of the processing base, and one clamping can complete the processing of the cavity and all the holes.
