Japanese Made Worm/ Worm Gear

High Positioning Accuracy!

Long Service Life!

The rotary table employs the Japan-imported worm/ worm gear, featuring high accuracy, maximum wear-resistance and long service life.

Easy To Adjust Backlash

Positioning Accuracy Ensured

Easy To Adjust Backlash

After the worm/worm gear set has been operated for a long time, excessive backlash between both may occur. It may affect the positioning accuracy of the rotary table. When this occurs, simply adjust the worm for reducing backlash, then the rotary table will return to its normal positioning accuracy.

Extra Large Radial/ Axial Bearing

The rotary table is fitted with extra large radial/ axial bearing, providing outstanding load resistant capability in radial and axial directions. In addition, the rotary table features high rigidity and minimum deformation.

Rigidity is 2~3 times greater than that of conventional bearings.

 

                                               

Full Circumference Brake No Runout. No Displacement

By applying the hydraulic power to clamp the entire circumference, the table runout problem can be avoided.

Unlike the conventional disk brake, the full circumference brake provides greater clamping force and no vibration, ensuring high machining accuracy of the machine.
