Kennametal Makes Turrets More Flexible And Collet Chucks More Capable

Available in sizes ER25 through ER40 with thread sizes ranging from M08 through M16, new turret-adapted clamping units (TACU) and solid ER collets give live tool lathes machining center-like capabilities.

Kennametal expands its line of turret-adapted clamping units (TACUs) with ER-ready driven units.

Kennametal’s solid ER collets in sizes ER25, ER32, and ER40 are compatible with any standard ER collet chuck and any ER turret-adapted clamping unit (TACU).

Kennametal turns a CNC lathe machine into a milling machine by providing access of any small-diameter screw-on milling cutter to ER-driven units.

Kennametal Inc. (Pittsburgh, PA) expands its turret-adapted clamping units (TACU) line with ER-ready driven units and adds solid ER collets that are threaded to accept screw-on milling cutters. The products give shops the flexibility to use standard ER collets with solid end mills or the solid ER collets with screw-on indexable milling cutters.

Available in sizes ER25 through ER40 with thread sizes ranging from M08 through M16, this innovation gives live tool lathes machining center-like capabilities.

Sealed for through-the-tool coolant with a 1-millimeter standoff for additional clearance on larger end mills with a precision-ground locating boss for minimal runout, the very compact design reduces the chance of interference on smaller machines. They’re very rigid compared to a standard spring-style ER collet, enabling heavier cuts.

The TACU offering can be used on seven major brands of CNC lathes, both verein deutscher ingenieure (VDI) and bolt-mounted turrets (BMT) with a variety of static and driven blocks. TACUs are equipped for internal and external coolant with up to 12,000 RPM possible on specified driven tools.
