Features
■The machine adopts wheelhead moving
principle with column right-placed. New design and reasonable structure of
saddle and column, good rigidity of the machine and high power of the
wheelhead.
■Vane-type oil pump driven for table longitudinal movement and wheelhead cross
movement, to ensure smooth movement, low noise and low temperature rise.
■ Teflon-laminated guideways.
■ Rapid elevation mechanism provided for wheelhead vertical movement, feed can
also be carried out manually.
■ Hydraulic-driven for wheelhead cross
feed.
■ Auto lubrication system for guideways and leadscrews.
■Accuracy complies with GB/T4200-1983.
