English term or phrase:drive center (lathe)
Me encuentro con este término en el siguiente contexto:
Lathe accesories include tool rests, faceplates, drive centers, spur and live centers, drill chuck and arbor, drive belts, etc.
A drive center, also known as a grip center, is used in the driving end of a machine (headstock). It is often used in woodworking or where softer materials are machined.
It consists of a dead center surrounded by hardened teeth, which bite into a softer workpiece allowing the workpiece to be driven directly by the center. This allows the full diameter of the workpiece to be machined in a single operation, in contrast with the usual requirement where a carrier is attached to the workpiece at the driven end. The use of modified shell end mills in a drive center, instead of hardened pins, enables better gripping and prevents breakdown time due to pin stop.
