When you aspire to create one of the most competitive tool holders on the market, the details count. We invest heavily in extensive automation manufacturing and top of the line Mazak and grinding machines while pouring our heart and soul into bringing the tool to life. While not satisfied with just being good, so through customer data and rigorous testing, our R&D team are able to blend over 40 years of manufacturing know-how and real-world feedback to improve the tool holder's design and performance.
We optimize our process for both efficiency and accuracy by utilizing Kawasaki robotic arms to load and unload bar stock into the Mazak multi-tasking machine centers. We use SCM420 alloy steel to lay the foundation and case harden to RC 57-59 with a core of RC 34-39 to provide good core strength and maximize wear life. The core creates a dampening effect which reduces vibration in high speed milling to improve surface finish. The AT3 or better taper accuracy ensures 80% or better taper contact with spindle and using Stotz Air/Electronic Gaging for inspection on the taper. We precision grind the internal bore surface to <.0002" TIR and all bores are ground on a CNC grinder to ensure close run-out tolerance and evenly contact between the collet and the bore pocket. We use Haimer laser balancing machines to deliver a tool that can operate flawlessly at 20000 RPM and Mitutoyo or Mahr indicators to check the run out.
Taper ground to AT3 or better specification ensures 80% or more contact with spindle to reduce harmonics, improve runout tolerance and deliver consistence performance
Precision mill finished from multi-tasking Mazak machine on the flange face to eliminate the 1/8" gap between flange and spindle nose to minimize vibration
No longer having an off-center internal collet ring, this collet nut's internal clamp is designed with balance in mind while it's easy to snap-in snap-out ER collet

G2.5 20,000 RPM
With simultaneous contact on taper and flange face between the spindle and tool holder, dual contact tooling eliminates the 1/8” gap between the flange face and the spindle nose to increase rigidity, minimize vibration, extend cutting tool tool life, and greatly improve workpiece surface finish at aggressive speed & feed
By utilizing DONE IN ONE capability from Mazak Integrex machine with a second turning spindle, all processes from raw bar stock material to final machining in just one machine to improve machining accuracy and streamline production output.
Innovative coating process significantly increases the clamping force by 75% compared to standard ER collet nut. More gripping force provides better rigidity and reduces the possibility of losing grip on the round shank which lead to expensive damage on cutting tools and work piece material.
