Rotary Table Brother T-200A

Roller Gear Cam Mechanism

• High accuracy: High-accuracy machining achieved by mechanism with no backlash.
• High productivity: Achieved by the maximum speed of 100 min-1.
• Extended service life: Permanent high accuracy with very little deterioration over time.

Roller Gear Cam Mechanism

By preloading the input and output shafts beforehand, the four cam followers can be always kept in contact with the cam surface, which eliminates backlash and provides high rigidity.

In addition, the cam followers that rotate can transmit the motor torque efficiently, and therefore, they can rotate at low torque and be used for a long term, without wear and adjustment.

High Productivity

Combining the roller gear cam with the proper motor provides high acceleration and high rotation speed. In addition, machining can be performed only by the holding torque with motor without using the clamp mechanism depending on the machining load.

• Max. speed: 100min^-1
• ( 0→180 degree Indexing time )
  Clamp mode : 1.05 sec.
  Unclamp mode : 0.45 sec.

High Accuracy

Backlash can be eliminated with preloading the cam followers. Even machining with the turning direction in reverse will not adversely affect the machining surface.

• Indexing accuracy : 10 sec. or less
• Repeatability : 4 sec. or less
