Heimatec’s U-tec flexible adapter system is available on all right-angle heads in the company’s line, and models are available for most machine tool lines in the North American market, the company says. It plans to include its adapter system on all angle heads going forward. Most notably, the company says this development provides the rigidity and quick-change capabilities necessary in deep-hole drilling applications using extended tools.

The tool adapter system enables a standard ER output live tool to accept various adapters for different applications. This enables users to quickly change over tools on virtually any lathe or mill using a single live tool instead of purchasing a quick-change system, the company says. A face mill adapter, for example, can be quickly positioned into the standard holder without the need for a completely new base. This is said to reduce inventory costs and change-over time.

The polygonal drive system is designed to promote high-power transmission stability and faster setup while avoiding loss in performance or accuracy due to the live tool base remaining in position while only the adapter and collet are swapped out. The system features collet nuts with an internal threading for rigid mounting. Additionally, the adapter system enables the cutting tool, with its short and compact design, to be brought into closer proximity to the bearing. Internal coolant as high as 2,000 psi (140 bar) is provided as standard.

Every adapter in the system, complete with any necessary clamping nuts and adapters for arbor, Weldon, CAT 40 and CAT 50, is now available in shell mill, face mill, ER extension, side-lock, shrink-fit, hydraulic and blank styles. The company’s angle heads are compatible with a variety of automatic tool changers, feature 360-degree manual positioning and include torque arms and a stop block. Torque is rated as high as 150 Nm (110 foot-pounds).
