Product Description
1. Heavy duty box jaws used on heavy duty lathes, vertical boring mills, etc. as workholding for huge and heavy workpiece. Jaw base 450mm long and rows of bolts holes 240mm apart. Other sizes can be customized on this type or boring mill jaws;

2. This set of jaws are used on a heavy duty lathe with 2500mm swing over bed and supporting workpieces up to 120 tons with only the chuck clamping and the center supporting. With the mechanical clamping boosting gear set, one operator can drive each jaw to generate adequate to clamp the 120-ton workpiece. To help to increase the clamping force generated by each jaws, lubrication grease nipples are furnished on the top jaws and jaw base so that grease can be injected into the internal guide ways of jaw box and the screws to reduce the friction coefficient.
