Model： M7163
Type： Hydraulic surface grinder
【Instruction】
The machine uses left-column, side-mount tray and grinding head layout. The applying of technology of sophisticated mobile grinding head makes our products with good rigidness.
The shell grinding head is driven by built-in 7.5KW motor in order to ensure a good cutting effects.
The working table moves longitudinally (left and right) and uses a V-flat guideway and artificial and precise shovel. The hydraulic system uses an advanced oil pump motor and integrated hydraulic contron unit with high precision and ease-maintenance. The working table’s longitudinal movement is driven by vane pump with smooth motion and low noise.
