Greer, SC — 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 A2100 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° 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.

Potential benefits include quick and precise tool changes of ±0.00008 in. (±0.002 mm), less non-productive time because of fast tool changes, a wide application range for all industry segments, universal use for turning operations and easy handling.

The QuadFit interface allows quick and easy replacement of exchangeable heads, with perfect positioning and repeat accuracy. When fitting a QuadFit exchangeable head, clamp the A2100 boring bar to an assembly block or directly into the lathe tool adaptor. Ensure the tool-side and machine-side QuadFit 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.
