hey everyone just researching about gearbox components and thought I would ask some questions before I get into it properly
I have a two speed gearbox in my cnc lathe with hydraulic solenoids to change gear and sensors to check it is in correct gear and I have a spindle encoder 1 to 1 on spindle Actual spindle rpm is currently being read in linuxcnc also spindle output from my 7i76 pot is connected up to the fanuc old vfd and working fine. and I can run in both directions fine currently I can rigid tap and thread cut fine etc just want to set up auto gear changing depending on rpm and also would like to be able to lock gear into high or low. auto gearchanging is probably less of a concern than being able to lock to a certain gear as normally the whole job would be done in either high gear or low gear depending on size of the part. spindle speed goes from 0-3000 rpm and low gear is half speed so I have a 11kw motor geared down to halve speed and double torque which should be sweet for heavy cuts what is my easiest best option guys? I could fudge something in classic ladder but I know that there are several gearbox components built that should work for me regards Andrew _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
