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.
Far from being outdated by the latest machine tool technology, angle heads often prove an ideal complement by pushing done-in-one capabilities even further.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.
Angle heads can enable a three-axis machine tool to be more versatile. That said, this shop explains that there’s more to getting started using them than simply loading them into a machine’s spindle.
A seemingly small amount of runout can still be too large for the tool. Reduce this runout, and tool life or productivity may dramatically increase.
