The Titespot keyseat cutting head is said to eliminate costly secondary broaching or milling operations on gears, sheaves, hubs and pulleys. Designs for machining center use load easily from the automatic tool changer. A lathe version allows keyseat cutting to be combined with turning and boring operations. Both versions are available in the popular shank styles.
The head incorporates a positive displacement ball piston motor powered by a high-pressure (300 to 2000 psi) coolant system. A 6.5:1 gear reduction generates up to 10 foot-pounds of torque at 1000 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. Multiple passes can produce odd-sized or wide keyways and 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" ID. Cutters are available in widths from 3/32" to 1/2". Other applications include slotting and oil grooving.
