ECK25 Series CNC Vertical Lathe for Piston(ECK2512A/ECK2516A)
Views:832 Date:2021-09-09?

Function introduction:

The machine tool adopts a vertical structure with hydraulic tailstock?or pneumatic?tailstock?(optional servo tailstock)?and is equipped with?a new generation of EJX1260A flat linear servo cutter(a patented product of EPOCH NC) and a dedicated driver,?which can process middle-convex irregular ellipse or other?complex shaped piston contour and solid-cam for piston.

Equipped with?eight-station hydraulic turret or Gang-type tool holder, which can complete finishing of piston contour and ring groove、ring groove chamfering?and top surface finishing?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?that required by piston.

The standard SIEMENS 828D system?is adopted, for which the programming is flexible and convenient, and the reliability is high.

There are two ways for clamping pistons of the machine tool, the one is pneumatic tightening with tailstock/hydraulic/servo?tightening, and the other is pneumatic/hydraulic?tensioning, which can be chosen by users according to their technology.
