Product description :

◆The machine bed, slide seat, column, grinding head body, table and other basic parts are all made of high strength cast iron, stable organization and permanent guarantee of quality.
◆The spindle of the grinding head is made of static and static pressure structure and high rigid spindle sleeve structure.
◆The machine adopts high precision lead screw, which increases the transmission rigidity and eliminates the influence of thermal deformation during movement, ensuring the accuracy of the machine.
◆The working table moves from side to side driven by the variable vane pump and adopts the closed hydraulic system, whose speed is stepless regulated by the regulating handle on the bed body .
◆The machine adopts ttype layout, and the guide rail is attached with teflon soft belt, which has good directivity and stable movement.
The machine has strong rigidity, small thermal deformation, stable movement, low noise, low oil tank temperature rise, high grinding accuracy and convenient maintenance.
◆The electrical box is equipped with a heat exchanger, which can effectively control the temperature in the electrical box and ensure the long-term stable operation of the control system.
