Heimatec, a world leader in live tools, angle heads and multi-spindle drill heads, today announces immediate availability of its popular u-tec® flexible changing system on all live tools in the company’s product line. Tools are now available for the most popular machine tool models in the market, according to Platinum Tooling Technologies, Inc. President, Preben Hansen. Platinum Tooling is the exclusive North American importer. The company plans to include its u-tec® flexible changing system on all live tools and angle heads, going forward, according to Hansen. He notes this design offers the benefits of quick change, while maintaining exceptional rigidity.
The u-tec® patented changing system allows a standard ER output live tool to accept various adapters for different applications. This allows users the ability to have quick changeover of tools on almost any lathe or mill, using a single tool, without having to commit to a quick-change system on the initial purchase. A facemill adapter, for example, can be quickly positioned into the standard holder, without the need for a new tool purchase. This significantly reduces inventory costs as well as changeover time for the busy shop.
The u-tec® system, according to Preben Hansen, “…represents a real improvement in lathe live tooling design. u-tec® allows great user flexibility and ensures a solid connection due to the polygon design built into both the tool and the adapter. This polygon connection helps guarantee the proper position and alignment of the adapter inside the tool. Once the insert is properly positioned and the collet nut is clamped, the cutting tool will have excellent rigidity and torque transmission.”
He further explains the unique collet nuts on the u-tec® system have internal threading for clamping stability and that this new tool adapter system enables the actual cutting tool to be brought into closer proximity to the bearing, thus further improving performance in use.
Every adapter in the u-tec® system is furnished complete with the necessary clamping nut and holding wrench. u-tec® adapters are available in various outputs such as arbor, Weldon, ER extension and blank styles.

Shaft used for rotary support in machining applications. In grinding, the spindle for mounting the wheel; in milling and other cutting operations, the shaft for mounting the cutter.
Flexible-sided device that secures a tool or workpiece. Similar in function to a chuck, but can accommodate only a narrow size range. Typically provides greater gripping force and precision than a chuck. See chuck.
Milling cutter for cutting flat surfaces.
Turning machine capable of sawing, milling, grinding, gear-cutting, drilling, reaming, boring, threading, facing, chamfering, grooving, knurling, spinning, parting, necking, taper-cutting, and cam- and eccentric-cutting, as well as step- and straight-turning. Comes in a variety of forms, ranging from manual to semiautomatic to fully automatic, with major types being engine lathes, turning and contouring lathes, turret lathes and numerical-control lathes. The engine lathe consists of a headstock and spindle, tailstock, bed, carriage (complete with apron) and cross slides. Features include gear- (speed) and feed-selector levers, toolpost, compound rest, lead screw and reversing lead screw, threading dial and rapid-traverse lever. Special lathe types include through-the-spindle, camshaft and crankshaft, brake drum and rotor, spinning and gun-barrel machines. Toolroom and bench lathes are used for precision work; the former for tool-and-die work and similar tasks, the latter for small workpieces (instruments, watches), normally without a power feed. Models are typically designated according to their “swing,” or the largest-diameter workpiece that can be rotated; bed length, or the distance between centers; and horsepower generated. See turning machine.

milling machine ( mill)
Runs endmills and arbor-mounted milling cutters. Features include a head with a spindle that drives the cutters; a column, knee and table that provide motion in the three Cartesian axes; and a base that supports the components and houses the cutting-fluid pump and reservoir. The work is mounted on the table and fed into the rotating cutter or endmill to accomplish the milling steps; vertical milling machines also feed endmills into the work by means of a spindle-mounted quill. Models range from small manual machines to big bed-type and duplex mills. All take one of three basic forms: vertical, horizontal or convertible horizontal/vertical. Vertical machines may be knee-type (the table is mounted on a knee that can be elevated) or bed-type (the table is securely supported and only moves horizontally). In general, horizontal machines are bigger and more powerful, while vertical machines are lighter but more versatile and easier to set up and operate.
Process of both external (e.g., thread milling) and internal (e.g., tapping, thread milling) cutting, turning and rolling of threads into particular material. Standardized specifications are available to determine the desired results of the threading process. Numerous thread-series designations are written for specific applications. Threading often is performed on a lathe. Specifications such as thread height are critical in determining the strength of the threads. The material used is taken into consideration in determining the expected results of any particular application for that threaded piece. In external threading, a calculated depth is required as well as a particular angle to the cut. To perform internal threading, the exact diameter to bore the hole is critical before threading. The threads are distinguished from one another by the amount of tolerance and/or allowance that is specified. See turning.
