Zhejiang University's announcement on correction of backpack rigs

Features of CNC roll turning lathe:

      This CNC roll turning lathes are mainly used in the semi finishing and finishing turning processing work for cast iron, steel and Non-ferrous metal rolls. The machines adopt high speed iron steel, tungsten-carbide or other kind of material cutters. These kinds of designs support the machines to do turning and repairing processing work for the rolls` ex circle, head face, all kinds of complex groove face and curved surface. They can also process the similar cast iron, steel and non-ferrous metal shafts as rolls in same weight range for semi finishing and finishing work on ex circle, head face, and all kinds of complex groove face.

      The machine adopts four guide way or four in one guide way made of one-piece casting. The longitudinal and cross movement adopt high rigid rectangular guide way .With the combination frame blade holder of high rigid cutter row on the rectangular, the machines have improved the rigidity and stability. We adopt high accuracy and radial clearance of the double row short cylindrical roller bearings as machine`s spindle bearings to ensure the machine`s high rigidity, stability and high accuracy. All the designs make sure the machines in integrated processing precision. And the work pieces will be processed in high accuracy.

      Machines adopt paste hardened plastic guide way and centralized lubrication systems for every guide ways` lubrication. It uses fixed-point quantitative oil supply principle. This ensures that the dynamic response of the system and the long using life for the machine`s guide ways` lubrication. Machines adopt full stainless steel covers for guide way. This kind of design will keep the machine`s accuracy.
