There is a "program check" on the control that will show you the spindle speed among other things. Its been a while I don't recall which switch it is? As for controlling spindle speed from hardware of software, I don't understand what you are saying? You can program spindle speed into the program, you can "mdi" in a spindle and on some machines you can use a spindle speed override switch. Most lathes I ran or programmed in the past I used constant surface speed in which the feed and speed are controlled by the surface speed, so the speed and feed change all the time? |
