When formulating the processing plan of the parts, we must first choose a reasonable precision benchmark for CNC vertical lathe processing. This requires that during rough machining, consider what rough datum to use to machine each surface of the fine datum, that is, each positioning datum used on the CNC vertical lathe should be processed in the previous ordinary machine tool or CNC vertical lathe process, so that it is easy to ensure that each The precision relationship between the machining surfaces of the station.
Moreover, when some surfaces are to be completed by multiple clamping or other machine tools, choosing the same reference positioning as the design reference can not only avoid positioning errors caused by the reference misalignment, but also ensure the machining accuracy of CNC vertical lathes. Simplify programming.
The search of the workpiece processed by the CNC vertical lathe is to make the center of the workpiece coincide with the rotation center of the worktable. Alignment should be carried out when the workpiece is not fully clamped and positioned. When aligning, the clamping force of the clamping mechanism should be adjusted at the same time, until the workpiece meets the technological requirements after alignment, then the CNC vertical lathe will clamp, position and align At the same time.
The fixed cutting speed of CNC vertical lathe processing ensures the accuracy of its processed parts. It controls the spindle speed of the CNC vertical lathe. The constant cutting speed can be achieved through the G96 command in the control system. The program controls the DC motor or variable frequency three-phase motor. To execute the constant speed command.
