Hardened and ground gears made of Ni-Cr alloy are used in headstock for durability.

Horizontal arm has hardened and ground slide way for precise headstock movement.

Vertical column has safety device to prevent arm from dropping.

Machine base is made out of heavily ribbed casting for stability. It is equipped with T-slots for easy clamping of work piece and drain channel to direct coolant flow.

Arm elevation is controlled by electric motor.

For Models RD-1230 and RD-1600

Vertical column utilize double tube construction.

Spindle is equipped with counter balance measure.

Clamping of the arm, column and headstock is done by electric or hydraulic motor.

For Model RD-1600

Clamping of the arm, column and headstock is done by independent hydraulic motor.

The headstock is equipped with built-in lubrication system.

Headstock is equipped with over-load clutch to protect the gears in case of spindle over load.

Headstock has rapid spindle return feature, along with the clutch, it speeds up the tapping procedure.

Built in automatic tool ejector for easy tool change.
