Introduction
BJ series gap-bed lathes can perform internal and external turning, taper turning, end facing, and other rotary parts turning; Threading Inch, Metric, Module and D.P.; Perform drilling, boring and groove broaching; Machine all kinds of flat stocks and those in irregular shapes; Respectively with through-hole spindle bore, that can hold bar stocks in larger diameters; Both Inch and Metric system are used on these series lathes, it's easy for people from different measuring systems countries; There are hand brake and foot brake for users to choose; These series lathes operate on power supply of different voltages (220V、380V、420V) and different frequencies (50Hz、60Hz).
