Conventional Lathes

Conventional lathes of c630-1b,c630-1bg,cw6163b,cw6180b,cw61100b can undertake various turning works such as turning internal and external cylindrical surface, conical surface and the other surface of revolution and end face etc.; tuning all kinds of common threads: metric thread, british thread, modulus thread, and diameter pitch thread etc. The dimensional accuracy of parts and axles processed by the machine tools can be up to it6.
the gap-bed lathes like c630-1bm, c630-1bmg, cw6263b and cw6280b series increase the swing diameter of spindle and are suitable for machining discoid and non-circular parts with bigger diameters.
the key components of machines adopt ht250 high strength grey cast iron and have passed three-step aging treatments: artificial aging- 6-month natural aging - vibratory stress relief after rough machining and 2-month natural aging again, which can ensure the stability and reliability of machining, the accuracy of reliable sizes, resistance for heavy cutting and they can keep the machining accuracy for a long time. The slide way of the machine tool has been made by supersonic frequency quenching and it has been accurately grinded by guide-way grinder with high precision, and the saddle rails adopt plastic treatment so that it decreases the friction coefficient and reduces the wear for slide way of the machine tool. The spindle is made of hot-rolled heavy-walled steel tube (45 #) and it goes through thermal refining and elaborately machining. Front and rear spindle bearings are all used high-speed spindle bearings of domestic well-known brands, which can withstand radial and axial forces simultaneously.
