DRILLING

 

 

 

  • The arm is made of high-class cast-iron. Arm slide is under strick heat-treatment and grinding.
  • The bearing bracket of gear-box uses stand-ardised bearing to fit arm slide. This makes the gear-box can be operated on the arm slide smoothly.
  • The high-speed gears in the gear box are made of Nickel-Chrome alloy steel and under strick heat treatment with accurate grinding.
  • 2HP motor can provide diverse speed selection under heavy-duty cutting.
  • the main spindle is balanced by special spring. And it is more durable than all traditional balance mechanism.
  • The over-load protective devices can secure the operator against injury.
  • The arm-clevating is controlled by a cross-switch and driven by Copper nut/Leading screw which can reach the ideal working height stably. Futhermore, the safety device can prevent the arm from falling due to wear of the elevating copper nut.
