Original Press Release:

High-Speed PRECI-FLEX® Tooling Available for Mazak Turning Centers

EXSYS Tool, Inc. has expanded its industry-leading line of PRECI-FLEX® modular tooling systems to include a 10,000-rpm, 1:1 ratio rotary tool for Mazak QUICK TURN and QTU Series Turning Centers. The faster toolholders effortlessly match the processing speed of optional 10,000-rpm machine spindles to boost productivity and achieve excellent surface finishes.

Manufactured by EPPINGER, PRECI-FLEX offers unmatched flexibility, precision and cost savings. The short, compact design with monoblock housing assures maximum torque transmission and rigidity, resulting in increased machining accuracy and improved productivity. Additionally, PRECI-FLEX's conical and flat face planar interface allows the use of either an adapter or a standard ER collet, and enables collets, endmill holders, expanding collet chucks and shrinks fit tooling to be mounted on a single base holder.

The tooling system also features an EXSYS/EPPINGER Compensating Clutch with a floating coupling between turret drive motor tangs and toolholders that automatically compensates for any misalignment. The resulting high-precision alignment reduces vibration and tool chatter, which, in turn, makes for longer tool life and better surface finishes.

Available in a range of sizes, the 10,000-rpm, 1:1 ratio PRECI-FLEX is available in Horizontal (H) type 90-degree radial holders and Vertical (V) type straight off-set axial holders. Every toolholder provides unsurpassed repeatability within five microns. The system also virtually eliminates machine downtime and allows tooling adapters to be interchanged between fixed and rotary base holders for fast, economical machining.
