KURT Manufacuring, represented by DoALL Australia , has released new ToolBlox modular tombstones in two-face and four-face models provide lighter weight options for designing and building high density workholding for today's high speed horizontal machining centres.

With a weight of 30-40 per cent less than conventional cast iron tombstones, these ToolBlox provide new versatility and reduced cost for modular workholding.

Built of rugged A36 HRS steel, they are highly rigid to achieve workpiece immobility and to dampen cutter induced vibration using highest speed spindles.

ToolBlox modular tombstones are designed specifically to accommodate all types of workholding devices, including but not limited to, virtually all model Kurt single station, double station and multiple station vises, either manual or hydraulically actuated.

They can handle all types of clamps and modular fixturing including custom workholding devices and hydraulic components. They have bolt holes and dowel patterns on each face for fast installation and removal of sub-plates and workholding components which reduces setup time.

Two different size models of the two-face ToolBlox are available, the first with a 400mm square base and 320mm wide by 25 inches high mounting faces with estimated weight of 148kg.

The second model has a 500mm square base and 400mm wide by 28 inches high mounting faces with estimated weight of 248kg (weights include aluminum sub-plates).

Two different size models of the four-face ToolBlox are available: the first with a 400mm square base and 320mm wide by 25 inches high mounting faces with estimated weight of 111kg. The second model has a 500mm square base and 400mm wide by 28 inches high mounting faces with estimated weight of 164kg (weights include aluminum sub-plates).

Kurt also offers a variety of ToolBlox sub-plates available in A36 HRS steel or 6061 T6 aluminum for use on the ToolBlox modular tombstones. These sub-plates have optional hole patterns and/or keyways, are precision ground to ±.001 and are doweled for fast bolting to ToolBlox tombstones.

Kurt vices may be permanently mounted to these sub-plates for fast and easy setup changes on milling machines.
