Model： MY4080
Type： Hydraulic surface grinder
【Instruction】
The machine is made with the procedure of resin sand and aging treatment to prevent the deformation; adopts the cross saddle structure with good rigidity, excellent stability, great shape and easy to operate; is possessed with plastic coated guide and artificial and precise shovel in order to reduce the abrasion of the slideway and to ensure and extend the precision.
Grinding head moves up and down and uses worm and gear to reuce the weight of the decline due to grinding head’s force which causes the screw up and down in the grinding operation and grinding head feeds smoothly and protects the screw.
