optical switch for lathe index
« on: November 29, 2008, 03:33:29 PM »
i am in the middle of a retrofit of a hardinge chnc4 lathe.moving right along,x and z axis have e6d us digital encoders installed with gecko 320s.ab 1336 impact vfd  with 7.5 hp motor.reading of others and their trials and tribulations with the tool turret, controlled it  by geared head stepper motor with gecko 201  and a 5way solenoid air valve.   can anyone recommend an optical switch for the lathe index pulse? i cant mount a slotted disc so it has to be reflective.  thanks
