Determine the processing route
The machining route is the movement track and direction of the tool relative to the part during the machining process of the index-controlled machine tool.
1. It should be able to ensure the machining accuracy and surface roughness requirements;
2. The processing route should be shortened as much as possible to reduce the idle travel time of the tool.
The connection between machining route and machining allowance
Under the condition that the CNC lathe has not yet reached the popular use, the excessive allowance on the blank, especially the allowance containing the forged and cast hard skin layers, should be arranged on the ordinary lathe for processing. If it must be processed with a CNC lathe, it is necessary to pay attention to the flexible arrangement of the program.
Fixture installation points
The connection between the hydraulic chuck and the hydraulic clamping cylinder is realized by the pull rod. The main points of the hydraulic chuck clamping are as follows: first, remove the nut on the hydraulic cylinder with a wrench, remove the pull tube, and pull it out from the rear end of the main shaft, and then use Remove the chuck fixing screw by hand to remove the chuck.
