Key Features:
★ This machine tool is a three-axis CNC universal external cylindrical grinding machine (with the abrasive spindle horizontal feed X-axis, the worktable longitudinal movement Z-axis, and the abrasive spindle base indexing rotation B-axis) featuring two联动. The CNC system uses internationally or domestically renowned brands. It is equipped with automatic feeding, retracting, rough grinding, fine grinding, abrasive wheel correction, automatic compensation, and the abrasive spindle automatic rotation functions. With the addition of an automatic measurement device, it can achieve a full closed-loop grinding cycle.
★ The abrasive wheel stand features an automatic rotation B-axis driven by a torque motor, the abrasive spindle is of sleeve or floating/pressurized spindle type, the abrasive wheel stand guide rail is made of steel, the worktable guide rail is a flat V-groove plastic-lined lubricated rail, and the feeding mechanism and worktable movement are driven by a servo motor and ball screw.
★ The machine tool main body is cast from cast iron, featuring a fully enclosed protective casing, rear-mounted backpack-style electrical cabinet, and front-mounted rotating operating panel.
