My '91 VF-`1 did not come with the programmable coolant nozzle. I am too cheap to spend the $1600 so I am building my own.
The cables to the I/O board have the Spigot Up/Down, Turret CW/CCW, Tool#1 and Geneva marks. From these a micro-controller can determine which tool is being used and put out a PWM for a 1/4 scale model servo to position the nozzle.
The positions are stored in EEPROM and read in when powered up. The array is synchronized when the turret first reaches Tool #1. There are 256 steps for positioning. After one second the positioning speed increases. When the mill is powered off or there is a glitch in the power the current array of positions is stored back in EEPROM.
Instead of the single nozzle off to the side I am making a ring around the spindle (yes, it will fit through the turret door) with three nozzles. Loc-Line will connect it to the coolant manifold.
The programming is done, I have to make the hardware.
Although this is for a 16 tool turret it can easily be modified to 20.
Would this of interest to anyone else?
