Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece.This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations.
This basic hydraulic circuit of activating one hydraulic cylinder uses a three layer stacked valve assembly. First, it takes system pressure (normally ~2000 psi) and passes it through a pressure reducing valve (set for 560 PSI). In the figure this is the lower dashed rectangle of the three layer valve assembly.
The system pressure oil from the oil source in the original circuit is supplied to the roller balance circuit after decompression, and there is an energy loss at the pressure reducing valve; When the piston rod of the balance cylinder retracts under the action of the rolling mill screwdown system, the hydraulic oil in the rodless chamber of the ...
