This series of lathes is suitable for all kinds of turning work, such as turning inside and outside cylindrical surface, conical surface, other turning surface, end face, but also processing a variety of commonly used threads - such as metric, inch, modulus, diameter thread and drilling, Tapping, tipping trunking and so on. The machine can be processed steel, cast iron and non-ferrous metals and other materials. When the machine is finished, the roundness error is not more than 0.01mm, the cylinder degree error is not more than 0.04mm in the measuring length of 300mm; the torsion plane bed, the high quality cast iron is carefully manufactured and the induction hardening of the guide surface is precision, Bed width of 600mm; by the Teflon rail flexible rail composed of rails wear-resistant, vibration absorption, precision retention is good; spindle with three support structure, high rigidity, high precision, can be strong cutting. Spindle through the hole for the Ф100mm large hole; 18 wide speed range, you can choose a more reasonable speed; can be directly turning metric and inch thread; slide box has a fast moving body.
