MTM-930A
Product Features
  • 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.
