ECK6520 CNC Vertical Lathe for Piston
Views:97 Date:2021-09-09 

Function introduction:

The machine adopts a double-column structure with a hydraulic tailstock (optional servo tailstock) and hydraulic tensioning, and the double-column can be processed at the same time to cancel radial force effectively in cutting process. Thus the processing accuracy and efficiency can be improved greatly. It is equipped with new generation EJX1260A flat linear servo cutter (a patented product of EPOCH NC) and eight-stations hydraulic (servo) turret or Gang-type tool holder, which can complete rough and fine finishing of contour、ring groove and top of diesel engine/steel pistons in one clamping.

“Epoch Piston Curved Surface Data Processing Software” (independent copyright software product of EPOCH NC) is adopted, which can edit all kinds of profile data required by piston.

The standard double-channel SIEMENS 828D System is adopted, for which the programming is flexible and convenient, and the reliability is high.
