Gas Purging

When your application demands high-level quality end results. We offer the option of a gas purging facility integrated into your HSC headstock.

Gripper Chuck

All Key Plant HSC headstocks come supplied with a 3 jaw self centering machine chuck for internal and external clamping.

Elbow Jigs

We design, manufacture and supply a range of elbow jigs that can handle pipe diameters upto 50″. Ideal for welding elbow joints and alternating direction tasks.

DS14 Diameter Selector

Input the welding diameter of your workpiece. The DS14 automatically calculates the required RPM of the positioner table, and sets the speed demand in the inverter drive (VFD).

Precision Control

For workpieces that require the ultimate precision, we can provide rotational speed through a closed loop encoder feedback, for high accuracy speed control.
