Mapal develops hard machining grooving tool range with universal insert clamping toolholder

VersaCut tools use long-life inserts that are retained in the toolholder by a clamping jaw that presses them securely into a prismatic connection. Because of the large clamping force used, this arrangement provides the high stability needed for precision machining, but the design of the clamp also allows the inserts to be changed easily and quickly. The clamping jaw is recessed into the tool holder to ensure unimpeded chip flow and to protect the jaw against wear. In addition, because of the geometry of the inserts, the risk of damage to the toolholder, should the insert fracture, is virtually eliminated, explains Mapal. PcBN inserts for the VersaCut range are available in four standard types to suit all common machining applications, including recessing, groove turning, thread cutting and parting off. Mapal can also supply PCD-tipped inserts and custom-designed inserts to meet special requirements. All inserts have the same connection shape and size, which means that only one type of toolholder is needed for grooving depths up to 5 mm and grooving widths from 1.2 to 6 mm. The toolholder is available with a range of shank forms, including square designs as well as HSK-T and other modular systems. Special shank forms to suit particular user needs can also supplied.
