MM1040S centerless grinding machine

MM1040S centerless grinding machine

1, the main use and scope of application

This machine is mainly used to grind cylindrical parts with a diameter of 2~40mm and a 

length of less than 140mm. It can also grind rotary forming parts with a diameter of

 7~40mm and a length of less than 120mm, and taper parts with a diameter of less than

 1:20 and cylindrical parts with a diameter of 7~40mm and a maximum length of 300mm. 

It is suitable for large batch factories.

1.2 Features

1.2.1 The grinding wheel spindle adopts five-piece dynamic pressure bearing, which

 has large bearing capacity, good rigidity and smooth rotation.

1.2.2 The working speed of the guide wheel adopts AC motor frequency conversion. 

Easy to choose the right speed for parts with different diameters.

The main shaft of the guide wheel adopts an integral bearing block in the front and a 

rolling bearing block in the back, and there is an integral bearing block auxiliary support

 at the door cover, which has large bearing capacity, good rigidity and smooth rotation.

1.2.3 The guide wheel can be rotated at a small Angle in the horizontal plane, and the 

grinding wheel need not be trimmed into a cone when grinding conical parts.

1.2.4 The longitudinal movement of the grinding wheel dresser and the guide wheel

 dresser are driven by hydraulic, with uniform speed and high precision, and can reduce

 the labor intensity of the operator.

1.2.5 The shape guide rail of the two trimmers adopts the double V-shaped steel ball 

structure guide rail, which has the characteristics of sensitive shape, high precision and

 long life.

1.2.6 The feed movement adopts double V-shaped guide rail, which has sensitive movem

ent, high movement accuracy and long life. The feed mechanism adopts servo motor,

 turbo worm and rolling screw to realize handwheel-free operation. The size of the feed

 value is clicked according to the demand.

1.2.7 The reciprocating and punching action of cutting into the grinding can realize 

automatic circulation, and the coarse grinding, fine grinding and no spark delay can be 

set arbitrarily according to demand.
