Centroid Control Serial Numbers

Centroid control serial numbers are generally 4-digit, 5-digit or 6-digit numbers. For many years it was conventional to prefix the serial number with the letter "K" for mill controls, "T" for lathe controls, "M" for Magnum routers, and "A" for Ajax kits. However, the letters are optional, as the numbers fall in unique series.

See the Field Guide for more extensive descriptions and history of the various control models.

There was some crossover between mill and lathe designations. A few T39 lathe controls were assigned 3000-series numbers; a small number of T15 lathe controls were assigned 4000-series numbers; and at least one dealer turned a board-level T39 kit (2000-series) into a mill control instead.

Some 1000-series board level controls -- mostly Revolutions, but also some built by Tryax Associates in the UK -- had multiple controls grouped under one 4-digit number. For example, 1339B-1, 1339B-2, 1339B-3 and 1339B-4.

Router tables, water jets, punch presses and similar machines usually use mill controls.

Cylindrical grinders and similar machines generally use lathe controls.
