Customer Spotlight: Mitch Free, CEO, ZYCI CNC Machining

Wednesday, August 2, 2023

“The application knowledge and expertise from Lyndex-Nikken is invaluable in helping me solve challenges,” said Mitch Free, CEO, ZYCI CNC Machining. He uses SK collet holders and polygonal taper toolholders with his Okuma machines for machining aerospace and defense parts. Mitch leverages Lyndex-Nikken innovative tooling to help keep his shop running efficiently.

In the world of CNC machining, the difference between a successful run and a scrapped part often comes down to microns. For Mitch Free and the team at ZYCI, the partnership with Lyndex-Nikken ensures that every spindle turn is backed by world-class engineering. By integrating advanced toolholding technology with their Okuma platforms, ZYCI maintains the rigid tolerances required for flight-critical aerospace components.

Why SK Collet Holders?

The SK (Slim Chuck) Series is engineered for high-speed machining and superior gripping power. Unlike standard ER collets, the 8-degree taper of the SK system provides a more substantial clamping force and improved runout accuracy (3 microns at 3xD).

  • Reduced Vibration: Increased rigidity leads to better surface finishes.

  • Extended Tool Life: High concentricity ensures even wear on cutting edges.

  • Versatility: Ideal for everything from high-speed finishing to heavy-duty milling.

The Advantage of Polygonal Taper (PSC) Toolholders

Polygonal taper interfaces, often referred to as ISO 26623, offer a unique three-lobed shape that provides self-centering capabilities and high torque transmission. For ZYCI, using these toolholders on Okuma machines means:

  1. Repeatable Accuracy: Precise positioning for quick tool changes.

  2. Increased Torque: The polygonal shape prevents slippage during heavy radial cuts.

  3. Stability: The simultaneous fit on both the taper and the flange face maximizes contact surface, eliminating movement under load.

Delivering Excellence in Aerospace and Defense

Aerospace and defense manufacturing demand more than just “good” parts; they demand documented perfection and 100% reliability. By leveraging Lyndex-Nikken’s application expertise, ZYCI can tackle difficult materials like Titanium and Inconel with confidence.

The synergy between ZYCI’s machining prowess and Lyndex-Nikken’s innovative tooling creates a competitive edge—enabling faster cycle times, lower costs per part, and the ability to meet the rigorous quality standards of the world’s leading defense contractors.
