Tooling Blocks simultaneously provide multiple faces to hold components accurately in vertical plane for machining on Horizontal machining centres. Upon indexing of table a new face with new components is obtained for machining resulting into 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.
- Made from plain close grained gray cast iron conforming to Grade FG: 260 of IS: 210 and having hardness within 180 to 220 BHN.
- Castings stress relieved.
- Machined/Hand scraped surface finish.
- Top vertical block is provided in two types of construction viz square block having four faces for job mounting and rectangular block having two faces for job mounting.
- Tooling Blocks working (Vertical Block) faces offered with either (or combinations upon request) - T-slots, Holes or both as well as plane face only.
- T-Slots are of 18mm and have H8 tolerance
- Tapped holes are of 16mm size. Helicoil inserts can also be provided, if required, at extra cost,
- Bottom base provided with counter bored holes for fixing / clamping on machine pallet
- Offered in two grades of accuracies as under.
