Heimatec announces immediate availability of its newest development, the HT Series quick-change tool adapter system. With the HT Series onboard, users do not need to change tooling, only the adapter and that action is accomplished with a single clamping bolt. In this way, collet assemblies can be preset outside the machine tool, then simply swapped out as needed.
Whether a one-off job shop or long run production department, downtime on any machine tool is costly and the HT Series reduces changeover from an average of 15-20 minutes down to about that many seconds. The tool head stays in the machine, so less probing is needed after the changeover, as well.
HT Series offers users a lower initial investment, minimized tooling time, reductions of tooling quantities and related costs, plus considerably lower inventories. Further savings are realized by the high degree of flexibility in the system, the shortest gage line of any system on the market, meaning no additional tool length consumed, standard coolant-through design, exceptional repeatability to 0.0002" and easier handling of the components, resulting in lower setup costs.
This new quick-change system is available from Heimatec with all common outputs, including collet, extended collet, collet with tension and expansion for tapping, weld-on, weld-on extended, arbor, hydro-chuck, indexable insert holder, shrink fit and blank/plug design.
Related Glossary Terms
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.
- indexable insert
Replaceable tool that clamps into a tool body, drill, mill or other cutter body designed to accommodate inserts. Most inserts are made of cemented carbide. Often they are coated with a hard material. Other insert materials are ceramic, cermet, polycrystalline cubic boron nitride and polycrystalline diamond. The insert is used until dull, then indexed, or turned, to expose a fresh cutting edge. When the entire insert is dull, it is usually discarded. Some inserts can be resharpened.
Machining operation in which a tap, with teeth on its periphery, cuts internal threads in a predrilled hole having a smaller diameter than the tap diameter. Threads are formed by a combined rotary and axial-relative motion between tap and workpiece. See tap.
