Collet chuck sleeves for miniature boring tools

A line of collet chuck sleeves for the TinyMini-Turn miniature boring tool system enables quick changeover of solid carbide boring bars. TinyMini-Turn is designed for high precision internal boring, grooving, and threading applications in diameters down to 0.6mm (0.024").

The sleeve features an integrated collet chuck for precision clamping while the sleeve remains mounted in the tool post. A boring bar is changed by operating the sleeve’s clamping cap. The collet chuck provides full contact gripping on the boring bar shank for higher stability and repeatability compared to conventional bolt-clamp holders. The sleeve offers through-coolant supply for improved chip evacuation and tool life.

Case-hardened tapped, threaded shafts

Tapped shafts can be ordered with one or both ends tapped in case-hardened carbon steel or stainless steel. Threaded shafts also can be ordered with one or both ends threaded in case-hardened carbon steel. Diameters range from 0.25" to 1.50". Travel lengths sections available from 6" to 36".

Diameter tolerance of ISO g6 and straightness tolerances of 0.001" to 0.002" per foot are guaranteed. The case-hardened steel, precision ground shafts have a 10rms to 16rms micron finish. Case hardness is Rockwell C60-C64. The shafts are never annealed so outer diameters are ultra-precise.

24V gripper with IO-Link

The Schunk EGB with IO-Link compact mechatronic 24V gripper for small components satisfies the IO-Link Class B Standard and connects directly with an IO-Link Class B Master. Gripping force adapts to each workpiece via four software settings. The integrated measuring system detects the position of the gripper fingers across the entire stroke and monitors intermediate positions or varying workpiece sizes.

An integrated diagnosis tool monitors voltage, current, temperature, and gripper condition, automatically transmitting errors while operators store system maintenance intervals on the tool.

Brushless, maintenance-free servomotors and a clearance-free junction roller guide ensure efficiency and constant gripping forces across the finger length. Screws on the side or base increase flexibility while the gripper’s high-performance aluminum housing increases dynamics and energy efficiency.

The 24V gripper is also available with actuation via digital I/O.
