The rovolving speed is changeable during the machine is being operated. The gears are safe absolutely.
The total maximum height is 570m/m. Design of motor and gear box makes the point gravity center become only 280m/m. As the center of gravity is quite low and hard to be fallen, the magentic foundation can attain its function and efficiency.
The distributor disc is located on the top of machine which prevent it from being fallen or destroyed.
MTM-930A & MTM-922A with six-step speed variable (max. revolving speed: 756min revoling speed:51) depends on the hardness of processed objects and size of hole which makes the operator more comfortable to select the revolving speed.
