Not to be negative but this will be a can of worms.
Reason is the way this machine changes tools. Besides a pile of switches to tell the control where the tool carosel is, when you command a tool change:
the quill goes up; the machine files air cylinders to go to low gear verified by a micro switch in the "shoebox'; Volkman drive turns spindle slowly; another cylinder fires and a bar runs along a scroll in the gear that also gives spindle speed and locks it into orient verified by a micro switch; then the tool changer starts moving. this is air over oil and has a pack of micro switches on top to tell the control what is going on because more cylinders fire to slide a plate across the spindle to hold it up while the drawbar fires at the exact moment to release the tool and grab another. The tool arm literally slaps a tool up there. If the carosel needs to move 1 station, it strobes the air solenoid to the air motor to move it slow. If you load up the tool carosel, it must be balanced and you need to adjust a air flow valve to compensate for the additional mass or it will not move correctly. The air over oil arm mechanism also has flow valves but if you change the speed, you will upset the timing of the dozen or so switches involved in a tool change. Most of the solenoids are run by the CPL board in the control. You MUST have the maintenance manual to keep this machine running. It was called a BOSS 7 and was the first BOSS machine to use servo motors instead of steppers and even has backlash comp.
