Modern CNC machining centers and lathes can now perform almost any common machining operation efficiently. One of the last holdouts has been keyways and splines–always an expensive secondary broaching or shaping operation. Eltool’s Coolant Driven Keyseat Cutter now allows this operation to be brought online for the first time.
Eltool’s Titespot keyseat cutting head eliminates costly secondary broaching or milling operations on gears, sheaves, hubs, and pulleys. Designs for use on machining centers load easily from the automatic tool changer. A lathe version allows keyseat cutting to be combined with turning and boring operations. Both are available in all popular shank styles. The head incorporates a positive displacement ball piston motor powered by your high pressure–300-2,000 PSI–coolant system. A 6.5 to 1 gear reduction generates up to 10 ft. lbs. of torque at 1,000 PSI coolant pressure. Because the machine spindle is not required to rotate the keyseat cutter, spindle rotation can be used as an indexer to machine multiple keyways in one part. Odd sized or wide keyways can be produced by multiple passes. It is effective in both blind and through-bore applications. The heads are available in four standard sizes, suitable for machining in bores down to 1/2" I.D. Cutters are available in widths from 3/32" to 1/2". Other applications include slotting and oil grooving.
