M74140K立轴圆台平面磨床是采用圆形工作台承载工件或工装旋转，砂轮端面磨削工件平面形式一种平面磨床。工作台可采用电磁吸盘或花盘；立柱与床身采用三点调整机构联结，便于将工件平面磨成中凹或中凸形状；磨头主轴采用装入式大功率电机驱动，切削能力强；砂轮可采用筒形或多块砂瓦圆周均布组合式结构。本机床适用于大批量盘类工件平面磨削加工。金属行业如：轴承，盘类刀具，圆锯片，汽车发动机连杆，离合器摩擦片，液压件，泵阀门，磁性材料等；非金属行业如：耐火材料，陶瓷，玻璃，石英，大理石，碳纤维等。
M74140K Vertical Spindle Surface Grinding Machine with Rotary Work Table is surface-grinding machine designed to process work pieces on the rotary work table by the circumference of the grinding wheel on the spindle. The work table is in the use of an electromagnetic sucking device or Disc clicker; the vertical pillar and the machine tool bed are connected by the three-point position regulation system, which helps to process the work piece into inside cave shape or crown shape; the grinding wheel spindle is driven by a internal high-power loaded electric motor, which improves the grinding effect; the grinding wheel is in the use of either cylindrical shaped or even distributed trapezoid carborundum brick wheels around the circumference. This machine is used in the surface grinding process of mass-production disc type work. In the metal industry, such as bearings, disc type cutters, circular saw blades, automotive engine connecting rod, clutch friction plates, hydraulic pressure casting, pump valves, and magnetism material; in the nonmetal industry, such as refractory material, ceramic, glass, silica, marble, and carbon fiber.
