Product Description

MGK7363 High-precision CNC Horizontal Spindle Rotary Table Surface Grinding Machine

The MGK7363 high - precision CNC horizontal spindle rotary table surface grinding machine is a precision processing equipment that uses the periphery of the grinding wheel to grind metal materials. It can process the plane of workpieces with a diameter less than φ630mm and high requirements for flatness and surface roughness. The flatness of the workpiece plane can reach 0.003mm, and the surface roughness Ra value is not greater than 0.08μm. The worktable and the longitudinal movement (X - axis) of the bed and the vertical movement (Y - axis) of the grinding head, these two coordinate axes, both adopt ball screw transmission driven by AC servo motors. The Y - axis is also equipped with a linear encoder to form a closed - loop system, with sensitive feeding and reliable positioning. The function of CNC axis linkage can be used to grind inner and outer conical surfaces.

Series 73 Horizontal Spindle Rotary Table Surface Grinding Machines. This type of machine tool uses the periphery of the grinding wheel to grind the horizontal surface of the workpiece. The worktable can be adjusted in angle and rotated ±3° - 10° around the horizontal axis, and can grind the inner and outer conical surfaces of the workpiece. This type of machine tool has relatively high machining accuracy, surface roughness, and production efficiency. For models with a worktable diameter ranging from Φ400mm to Φ3500mm, it is suitable for the machining of disc - shaped cutters, piston rings, friction plates, bearing rings, gears after angle adjustment, and the repair and fitting of various planar parts. High - precision models can also meet the grinding processing requirements of high - precision annular components for aviation use.
