1, the main purpose of the machine tool, and basic components
1.1 the main purpose
Machine tools for special roll machine, mainly for the steel mill processing roll groove, the forming cutter, for all kinds of roll pass of coarse car, car, cut half fine processing and pass to repair. Also the outer cylindrical surface of the roll for rough machining and some other shaft parts processing.
The machine consists of lathe bed, headstock, tailstock, rest, rest parts, headstock and tailstock installed respectively on the left and right side of the bed end, tailstock can move along the bed ways or fixed, in order to meet the needs of the different lengths of workpiece.
Main transmission driven by an ac asynchronous motor, through mechanical variable speed spindle get to 12 levels of speed, feed system by the main shaft through light poles after mechanical variable speed make the rest get to 12 rank in different longitudinal and transverse feeding.
1.2 the basic component of machine tool:
The machine is made up of lathe bed, headstock, tailstock, slip board box, tool post, feed box, center the main parts, such as machine tool main drive driven by ac motor, by mechanical variable speed spindle can get 2 ~ 12 speed 90 r/min.
