Tooling Blocks (pallet mounting) play an important role in ensuring the maintenance of precision during work. The blocks simultaneously provide more than one face for holding components accurately in a vertical plane. This makes it easy to machine on horizontal machining centers and prevents any movement while working. The specific construction of our tooling blocks reduces downtime by eliminating multiple setups. Every time a table is indexed, a new face with new components is obtained. This is what reduces the downtime. Pallet mounting tooling blocks allow multiple fixture plates to be loaded and unloaded simultaneously and this helps in reducing the overall setup time. The tooling blocks also find their application in vertical clamping of components on Horizontal Boring Machines, Milling Machines, Horizontal Jig Mills etc. For custom requirements, contact JASH, the leading manufacturer and supplier of tooling blocks.
