RECESSING HEADS

This tool is used to make the grooves on the machines where circular interpolation is not possible. Industry standard configuration is available for the expansion grooves for Tube sheet and the Boiler drums. The tool is rotating in a machine spindle. The spindle is lowered, and the tool moves into position
The pilot is located in the bore against the face of the workpiece. Downward pressure causes compression of the recessing head, thereby actuating the slide mechanism which feeds the cutter out radially into the work.
The correct depth of cut is obtained when the micrometer stop bottoms against the front body, making it impossible to continue the cut. Groove location is controlled by the tool adjustment system on the shank end of the cutter
When the spindle is retracted, pressure is relieved, and the tool is withdrawn from the bore. The cutter retracts and returns to its starting position. The piloted bearing absorbs both thrust and rotation. It remains stationary in the bore of the workpiece, under load, until the cutter is fully retracted, thereby preventing scoring of the workpiece
