The standard series 2 Bridgeport N/C has a motorized knee with air assist. Killer for those really tough deep holes or plunging 4.625 ball end mills.

Nice commentary- you have my subscription. Your shredder is also quite nice. Come along way in 6 years huh! I hope your channel gets even more traction.

for the motor speed you can rig up a pulley over handwheel and use a stepper motor with a “at low speed” ref switch

I don't think adding 0.5 ohm resistors to the servos make any sense - you're loosing have the drive power as heat in the resistors. I don't know how the centroid servo drives work, but "real" servo drives (think Mitsubishi or Fanuc) have all sorts of protections built into them - it's actually pretty difficult to kill a real properly designed servo drive. The old ones have "issues" in old machines, but that's not due to the motor killing the drive, it's usually power supply issues in the drive itself that cause old servo amps to fail (and they're actually pretty easy to fix).

Its good to know that if I was using the typical servo amps It would be fine, but given that Centroid repeatedly states a shorted motor would damage their board, I was paranoid about damaging it. Ill have access to the machine in the future and can take off the resistors once the servos are replaced. I appreciate the comment.

Adding resistors should just make the motors harder for the board to drive as @gorak9000 mentioned-- I think you'd be better served here by doing the math to calculate what amperage you'd want to stop at to be safe (say if the resistance drops to 0.2 ohms) and adding appropriately sized fuses instead... I'm no EE tho so I'm sure someone knows more

Like your video I retrofit my bridgeport with a masso controller it works good now I'm thinking of retrofit my Hardinge cobra 65 that as Funoc 21-t controller looking to see if I can find some one has a vídeo how to do it

If the motors were running on the old control, they will be fine on the Centroid. Remove the series resistors going to the motor.

thanks, how long did it take you to do this whole conversation? I heard you say it took a few days just on hooking up the wiring from the computer to the motors and display panel . Does the the centroid computer hook directly to the the servo motors?

@SciCynicalInventing Жыл бұрын

The centroid controller board and the computer are two seperate things. And you would have a computer connect to the centroid board via an ethernet cable. Then that centroid board would be directly connected to the motors and everything else. It took me a week and a half approximately but I think realistically if you run into some issues it can take someone 2 weeks or so to fully install, tune, and calibrate everything. Thanks.

Hi there ,I just subscribed to yr channel, very interesting,u seem very smart,I am very interested in flybacks, do u think it would b possible to connect a fly back to a metal detector,and then plug the search coil into the fly back, to increase the magnetic field in the search coil, to make the detector go much deeper, I think u might b able to answer this for me, thank you👍😀

The knee usually is not motorized for the reasons you described.

A 5-7hp motor wouldn't require a "behemoth" VFD. A brand new 4kW Yaskawa GA500 costs us about $470 in the UK - or half that for a Chinesium equivalent. If you really believe the motors are full of copper and graphite dust, you need to dismantle them and clean them up - doesn't take long. A 0.5 Ohm resistor isn't going to do much for you.
