Drive and feed gear:
The rotating tool support is driven by a three-phase motor via spur gearing.
The setting of the two-step mechanical radial feed is adjusted by the control cam. An overload protective clutch prevents damage to the feed device when reaching the final position. In the Off-position of the machine the turning tool may be adjusted manually. The direction of feed is reversed by changing the direction of rotation of the drive.
The axial feed is adjusted by the feed wheel.

Clamping equipment:
The clamping equipment permits simple and safe clamping of the machine to the pipe. At the same time, the clamping device will center the machine to the pipe. By tightening the nut the 2 clamping cones are drawn together axially and the accommodated clamping cylinder is expanded
until it fits tight with the inside of the pipe. To simplify the procedure the clamping device can be fixed separately from the turning machine.

Tools:
The tools used are cutting tools with a 25 x 25 mm shank. Carbide cutting tools can be used either soldered or with throw away tips as well as high-speed steel tools. We can recommend well-tried tools.

Electrical equipment:
A ventilated totally enclosed squirrel cage three-phase motor is employed for drive. The motor is protected against overloading by a thermal circuit-breaker. The direction and the speed on rotation is selected, and the drive is switched on by means of the operation switch. The entire electrical equipment is in accordance with protection-type IP 44.
