High-quality Headstock and Tailstock features assures safety, precision and long-life

The series of head and tailstock positioners that we manufacture can be used for a variety of parts and weldments. A head and tailstock welding positioner is typically used for long rectangular shapes that must be supported from both ends. Railroad and truck frames can be positioned easily. Both fixed height rotation centerline and power elevating models are available for ergonomic placement of the weldment.

Screw Jack and Geared Elevation models are available. Optional manual and powered mobile sub-bases can be provided on rails for varying part lengths, which allow different length weldments to be positioned with one station. With a large rotation speed range, all welding processes can be accommodated, such as MIG, TIG, SAW, and Laser welding.

A typical configuration consists of a driven headstock positioner with an idler tailstock. Dual synchronized headstocks can be used for exceptionally long parts or parts that have torsion concerns. Robotic versions and manual applications can be accommodated depending on your specific needs.

This illustration show a typical heads and tailstock. They will handle long workpieces suspended between the tables on the head and tail units so that the work can be rotated around a horizontal centerline, something like a giant bench lathe. Long complex work can be turned to make the welds easily accessible to the welder.

The principal advantage of a headstock-tailstock positioner over a single gear-driven positioner is that a gear-driven positioner big enough to handle an equivalent long workpiece would require much more floor space. The reason is that the work would have to be mounted crosswise on the table of a geared positioner to turn like a propeller blade. If the work was secured only at one end, it would extend far ahead of the table. The extended workpiece CG and huge load moment would re­quire an enormous positioner base (even assuming that the extended workpiece did not deform under its own weight).
