Savings on exotics
Savings on exotics
Keywords: ACT, Tooling
A new evolution of toolholders has been added to the 2.2mm programme by Advanced Carbide Tooling Ltd which is claimed to show considerable savings on exotic or expensive materials. Parting off at only 2.2mm width rather than the conventional 3 or 4mm means that many more production components can be produced from every bar of material.
They now claim to be able to offer tooling with a full 21 mm reach to accommodate the industry standard for CNC bar fed lathes of 42mm diameter stock (Plate 9). In addition, the latest generation of toolholders incorporate an integral top clamp arrangement to guarantee the clamp always remains true and square over the insert when parting-off. The stepped down feature and side reinforcement also inherent in the design gives maximum rigidity at the point of cutting to ensure flat-faced non-dished parts.

Tools are available in shank sizes of 20mm and 25mm square, suitable for both left and right hand cutting operations. They can be used with all inserts currently available to achieve excellent surface finishes with good swarf and chip control properties. These include type NAC HSS TiN coated inserts for use when radial grooving in aluminium and aluminium alloys and where low surface speeds are required when machining exotic materials.
Type NBC inserts have a sintered-in groove for swarf control in long chipping materials when parting-off. Type NCC inserts incorporate a chip breaker feature for "difficult to control swarf" as encountered when working with bearing steels.
