Lyndex-Nikken SK Collet Chuck Advanced Design Optimizes Machine Tool Performance

Lyndex-Nikken, manufacturer and provider of high-performance machine tool accessories, offers SK collet chucks with an advanced design that optimizes machine tool performance.

To solve manufacturers challenges of having to frequently change collet chucks, which increases downtime, or having poor surface finish on workpieces, Lyndex-Nikken has designed their SK collet chucks with accuracy and precision in mind. The advanced design of the SK collet chuck provides increased rigidity and gripping force as well as the ability to reach tight spaces.

Due to a special heat treatment, grinding and custom slotting process enables Lyndex-Nikken to guarantee a 5 micron run-out tolerance for their "on size" fractional and metric size precision collets.

A titanium nitride (TiN) bearing nut improves rigidity as the uniquely designed gold ring reduces collet damage, reduces micro vibration with the collet flange, and eliminates friction with the collet. It improves the cutting rigidity and the quality of the cut compared to traditional collet chucks.

The taper angle provides increased gripping power as the SK collet chuck’s 8-degree collet seats deeper in the body of the holder, providing double the clamping force and precision than traditional 16-degree collets.

The narrow body of the SK collet chuck allows for access to tight spaces and provides better clearance making it ideal for machining complex parts.

The benefits of the SK collet chuck include:

• Lean – narrow body design allows access to tight spots
• Versatile – applicable for all milling, drilling, reaming, and rigid tapping applications
• Flexible – covers sizes from 0.028” to 1”
• Accurate – 2x more accurate than ER collet chucks, within 10x better repeatability
• Extremely Precise – 0.0002” or less concentricity guarantee with on-size collets
• Double Gripping Power – with an 8-degree collet taper, the SK collet chuck has double the gripping power over ER collet chucks

SK collet chucks are also available in Taper Plus which combines taper accuracy with flange rigidity. Additionally, SK collet chucks are available with coolant thru options - a unique high-pressure coolant collet system allows for higher accuracy and gripping torque.
