1、Structural characteristics of machine tools
This machine tool is a five axis three linkage precision CNC follow-up crankshaft cylindrical grinding machine. The control system design uses advanced and reliable devices as the machine tool control platform, with built-in follow-up grinding function modules, user-friendly human-machine interface, and complete equipment fault alarm and diagnostic functions.
The CNC system controls the movement of the X-axis (transverse feed axis of the grinding wheel) and Z-axis (longitudinal feed axis of the grinding wheel), as well as the C1 axis movement of the workpiece rotation grinding feed, and can achieve the linkage of the X and C1 axes. For large-scale crankshaft follow-up grinding, C1 and C2 (tailstock spindle, special attachment) linkage can be achieved according to the requirements of the grinding process when necessary. Equipped with PMC controller and LCD display.
The operator can set grinding parameters and edit the grinding process cycle through the display screen in a human-machine conversation, achieving automatic grinding of the machine tool. Automatic cutting in and periodic feeding can be achieved through program control, and electronic handwheel feeding can also be used.
