Machine Tool Accessories & Tooling Aids

Cast Iron Tooling Block simultaneously provides multiple faces to hold components accurately in the vertical plane for machining on Horizontal machining centres. Upon indexing of table a new face with new components is obtained for machining resulting in significant reduction of downtime by elimination of multiple set ups. Pallet mounting tooling blocks also enable simultaneous loading and unloading of multiple fixture plates thereby reducing total set up time. Tooling Blocks can also be used for vertical clamping of components on Horizontal Boring Machines, Milling Machines, Horizontal Jig Mills etc.

JASH Cast Iron Sub Table is used on a machining centre as ready fixture plates for tooling up. They allow easy, faster and repetitive setup on machine pallet and reduce changeover time thereby minimizing loss of operating time. They also help in protecting the surface of machine pallet and can also be used as sub-plates to provide space for the work setting.
