CJ 20, 22, & 26
Teach Lathe

Overview

The CJ-20, CJ-22, and CJ-26 are the most popular models in Kingston’s CNC teach lathe line, providing a convenient teach-in operating experience with a precise, versatile, and highly productive universal lathe. Now shipping with the intuitive new conversational Kingston App, it is easier than ever before to reduce cycle times and increase repeatability using CNC technology. The CJ-20 and CJ-22 come with a 3.125” spindle bore and lengths as short as 40”, while the larger CJ-26 comes uses a 4” spindle bore (upgradeable to 6”) and lengths up to 240” between centers. Ideal for a machine shop transitioning to CNC and for technical schools that train machinists, the CJ-22 and the CJ-26 and their intuitive conversational programming interface are a perfect bridge between manual skills and actual CNC programming.
