New Copy Turn Addition from Walter Delivers Stability, Accuracy, and Cost Efficiency

Walter’s new copy turning system for internal machining boosts tool life, cuts tooling costs, and can increase indexing accuracy by 50%.

Waukesha, WI — Walter has introduced the W1211/W1210 copy turning system for boring bars, imparting a higher level of dimensional stability and indexing accuracy to internal machining, including profiling (copy turning), facing, and axial grooving. These boring bars and indexable inserts with Walter Lock (WL) positive engagement successfully combat the high forces in variable directions that occur when internal profiling applications with V-style (ISO-V, 35° diamond shaped) inserts.

New Walter W1210/W1211 Copy Turn System.

The oblong shape of a conventional V-style insert leads to a very long pocket in the boring bar to hold the V-Shaped insert. Cutting forces are encountered far away from the actual support that the insert pocket provides to withstand the cutting forces. This results in increased wear, increased pitting of the pocket, less precision and an overall lack of indexing accuracy with all indexable diamond shape inserts such as VBMT or DCMT. With the robust, positive-locking insert seat design with three-point support, the Walter W1211/W1210 boring bars and WL25 inserts achieve outstanding stability, boosting tool life while enabling users to use the tools in both directions of travel, increasing indexing accuracy by 50%. 0.984, 1.260, and 1.575-in. (25, 32 and 40 mm): W1210 for profiling angles of up to 72.5° with a symmetric design and W1211 for profiling angles of up to 50°for a more robust support. The positive WL25 indexable inserts with three cutting edges are available in four insert types, depending on the requirements of the application: neutral, left-hand, right-hand and full-radius versions, and all fit into the same tool. In addition to the wear-resistant Walter Tiger·tec® Silver grades that are currently used, Tiger·tec® Gold inserts are also now available. The dual rake face cooling and the optional axial cooling for flushing out the chips during blind-hole machining also result in longer tool life and therefore greater cost-efficiency.
