Re: [CAD_CAM_EDM_DRO] linear motion and power

good morning "trend"
pneumatic actuating has here the big disadvantage, that there is nearly no
speed control possible. speed depends on load over the stroke of the
cylinder.
you can add a hydraulic speed control, that is used on lathes for accurate
sliding control.
i would keep my idea open to electro spindel operation.
regards
josef
