The vertical motion mechanism of MY250 hydraulic surface grinder adopts hydraulic transmission system, and the transverse movement adopts automatic feed system. The system consists of a set of motor, synchronous belt and synchronous belt wheel. The hydraulic system consists of a set of motor quantitative pump, pump maximum flow 18L/min, motor power 1.5KW, pump working pressure up to 3mpa, the system pressure is adjusted by the relief valve, the system main mechanical valve for grinder valve, by reversing control and throttle speed control of two parts, throttle valve speed control part and unloading function, can realize the workbench start and stop, The valve also has the function of buffer adjustment, the machine tool is easy to operate, high processing precision, stable motion, good thermal stability, low noise, easy maintenance.
Product characteristics ：
1、Wear resistance, light movement, high efficiency
2、No vibration, low noise spindle motor
3、After precision shovel flower, not only smooth sliding and wear-resistant
4、Durable, accuracy to maintain good, flexible and portable operation suitable for machinery, steel, energy, automotive, aerospace, Weapons, ships and other industries of large and medium-sized parts processing
