Compact Holders Speed Lathe Tool Changes
IMTS 2018: Exsys Tool Inc.’s Preci-Flex toolholders feature a short, compact design for improved accuracy and productivity.
Designed as a fast, accurate and cost-effective system for lathe tooling changes, Exsys Tool Inc.’s Preci-Flex toolholders include a single base holder and multiple tooling adapters that use an ER collet pocket.
According to the company, a short, compact design contributes to torque transmission and rigidity. This improves accuracy and productivity. In addition, a conical and flat-face planar interface enables the use of either an adapter or an ER collet. Collets, end-mill holders, expanding collet chucks and shrink-fit tooling can be mounted on a single base holder.
Available in a range of sizes, the toolholders provide repeatability within 5 µm. The system also reduces machine downtime and enables tooling adapters to be interchanged between fixed- and rotary-base holders to increase machining speed.
The combination of a digital boring head integrated with tool data software dramatically reduces the time required to set up a fine boring head. And still more IIOT-enabled advancements are just around the corner that will finally automate many boring operations.
Far from being outdated by the latest machine tool technology, angle heads often prove an ideal complement by pushing done-in-one capabilities even further. Proper application, however, requires attention to their limitations as well as their benefits.
The force that holds the toolholder in the machining center's spindle can weaken over time. If you haven't checked drawbar force in a while, this may be the weak link in your process.
