Cylindrical shank adaptor comes with quick-change system

Walter has introduced the A2100 boring bar/plain cylindrical shank adaptor with the QuadFit exchangeable heads for counterboring and internal profiling/copy turning. The main application areas are aerospace engines, pumps for the oil and gas industry, and general mechanical engineering.

The boring bar is available in 40, 50 and 60-mm diameters. With a dimension of 3×D, it is suitable for machining long bores.

Turning and boring heads are fitted on the boring bars/adaptors using the QuadFit interface for replacement of the heads. The exchangeable heads feature a precision-ground, tetrahedral polygon attachment that can be rotated 180 degrees for use overhead. The heads have a locating face for adjusting the center height and internal coolant delivery for optimum chip removal. A clamping nut enables quick tool changes.

The interface allows quick and easy replacement of exchangeable heads. When fitting a exchangeable head, clamp the boring bar to an assembly block or directly into the lathe tool adaptor. Ensure the tool-side and machine-side interfaces are clean. Use the exchangeable head in the standard or overhead position. Using a calibrated torque wrench for tightening the nut is advisable to achieve the recommended tightening torque, however a standard hook wrench can be used. When removing an exchangeable head, loosen the clamping nut using a suitable wrench, but do not use a torque wrench. Hold the exchangeable head and turn the nut manually until the head can be released.
