Headstock/Tailstock Positioner

 

Headstock/Tailstock Positioner

Headstock and tailstock positioners are ideal for parts that require repositioning during the weld cycle. Part rotation is servo driven, allowing robot and workpiece coordinated motion. Headstock and tailstock positioners can be configured to handle a wide range of part sizes from 1,000-kilograms to 10,000 plus kilograms.

Applications: —
Weight capacity: 1,000 Kg. to 10,000+ Kg.
