Kennametal has expanded its range of turret-adapted clamping units (TACU), which are now ER-ready driven units, and introduced a line of solid ER collets that are threaded to accept screw-on milling cutters.
Expansion of the successful turret adapted clamping units: ER-ready driven units. Solid ER collets in sizes ER25, ER32, and ER40. Compatible with any standard ER collet chuck, and any ER turret adapted clamping unit
“Together, the newly developed TACU ER units and solid ER collets are a great marriage of technology,” states Ronald West, manager – tooling systems. “Available in sizes ER25 through ER40, with thread sizes ranging from M8 to M16, this innovation provides machining center-like capabilities to live-tool lathes. These new products offer the flexibility to use standard ER collets with solid end mills, or the new solid ER collets together with screw-on indexable milling cutters.”
Sealed for through-the-tool coolant, there is a 1mm stand-off for additional clearance on larger end mills with a precision-ground locating boss for minimal runout. The system is of compact design, reducing the chance of interference on smaller machines. Compared with a standard spring-style ER collet, the system is designed to be very rigid, allowing users to take heavier cuts.

The TACU offer can be used on seven leading brands of CNC lathes, both VDI and bolt-mounted turrets, 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.
