The new type of horizontal axis moment table layout is adopted in this series of machine tools. The machine tool uses mature slow feed forming strong grinding technology, which can be directly grinded by blank, with advanced technology, high forming precision, high production efficiency and high automation.

The machine tool is mainly used for high-precision grinding of complex curved surfaces such as arc crown of heavy-duty gas turbine blade, inner and outer circles of guide blade, mounting plate and arc groove. It is especially suitable for surface processing of multi-directional, convex, concave, arc surface and other parts, including forming surfaces of various difficult to machine materials.

The forming wheel is used for grinding with large margin and slow feed force. This series of machine tools are gas turbine, steam turbine, aircraft engine, mold manufacturing and other industries.
