Lyndex-Nikken Collet Chuck Increases Gripping Force
SK collet chucks enables for access to tight spaces and provides better clearance, making it ideal for machining complex parts.
Lyndex-Nikken’s SK collet chucks feature an advanced design that optimizes machine tool performance. Lyndex-Nikken has designed its SK collet chucks to solve manufacturers challenges of having to frequently change collet chucks, which increases downtime, or having poor surface finish on workpieces. The collet chucks are said to be designed with accuracy and precision in mind, providing 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 provide a 5 micron run-out tolerance for its fractional and metric-size precision collets.
A titanium nitride (TiN) bearing nut improves rigidity as the specialized 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 toolholder, providing double the clamping force and precision than traditional 16-degree collets.
The narrow body of the SK collet chuck enables for access to tight spaces and provides better clearance, making it ideal for machining complex parts.
According to the company, the benefits of the SK collet chuck include a narrow body design that allows access to tight spots; versatile performance in milling, drilling, reaming and rigid tapping applications; flexible sizing from 0.028" to 1"; 2X more accurate than ER collet chucks, with 10X better repeatability; precise performance with 0.0002" or less concentricity guaranteed with on-size collets; and double gripping power with an 8-degree collet taper.
SK collet chucks are also available in taper plus, which combines taper accuracy with flange rigidity. Additionally, SK collet chucks are available with through-coolant options with a high-pressure coolant collet system for higher accuracy and gripping torque.
