Northfield Precision’s 5C collet chuck is interchangeable with its 4" chucks. The air-actuated chuck uses standard air-feed tubes (wet or dry), and the same bolt pattern as the 4" models. It can run at speeds faster than 8,000 rpm. All components are hardened and ground to 58/3 R.C., and all diameters are ground within 1/10,000 TIR. The chuck uses standard 5C collets.
The company’s air chucks are suited for virtually any lathe, boring machine, grinder or VMC. Models include through-hole, high speed and quick-change. The chuck is available in SAE or metric sizes ranging from 3" to 18" (76 to 457 mm). Accuracies range from 0.001" to 0.00001" (0.254 m).
There are usually better solutions to chatter than just reducing the feed rate. Through vibration analysis, the chatter problem can be solved, enabling much higher metal removal rates, better quality and longer tool life.
This new quick-change tooling system enables shops to get more production from their Swiss turning centers through reduced tool setup time and matches the performance of a solid tool.
