MT1040A Centerless Grinding Machine

This machine is suitable for the centerless grinding of cylindrical parts and annular parts and it is suitable for mass production. And it adds pitching-in structure, it can used in the centerless plunge-cut grinding of cone parts and shaped rotational parts, of which tapers are lass than 1:20.

Machine structure characters and performance

1.The overall arrangement of the machine adopts the method of the wheel frame's single movement

2.The grinding wheel spindle adopts the overhanging structure, and it’s convenient to exchange the abrasion wheel;

3.The grinding wheel spindle adopts multi-piece dynamic pressure bearing;

4.The guide wheel spindle adopts the overhanging structure, and it’s convenient to exchange the guide wheel;

5.The guide wheel spindle uses internal-type sliding bearing;

6.the guide wheel adopts AC frequency conversion infinitely adjustable-speed

7.An optional pitching-in structure, long parts continuous grinding frame, and cooling system can be chosen to strengthen its performance.
