★ This machine tool is a three-axis (X feed, Z1 grinding wheel, Z2 grinding wheel shaft) two-axis CNC compound grinder, primarily used for grinding the inner circular holes, inner tapered holes, step holes, inner ends, outer circles, and outer ends of workpieces. The grinding cycles are all automatically completed (including automatic feeding, retracting, rough grinding, fine grinding; automatic wheel adjustment, automatic compensation, etc.).
★ The machine tool employs a structure with workpiece feeding and a sliding table (grinding wheel stand) that moves left and right. Both the sliding table and the grinding wheel stand are equipped with rolling linear guides, all driven by servo motors via ball screw movement. The rotating speeds of the workpiece spindle and the grinding wheel spindle are controlled by a variable-frequency inverter to achieve stepless speed adjustment. The workpiece clamping is a hydraulic power chuck, and other matching fixtures can be configured according to the specific characteristics of the user's workpiece.
★ The machine tool features a fully enclosed protective housing, with a front-mounted rotating operating box and a rear-mounted backpack-style electrical cabinet.
