CNC PRESS BRAKE RETROFIT
Вставка
- Опубліковано 12 вер 2024
- I purchased a 90 Ton press brake with a CNC backgauge that didn't work properly and Automec wanted over $4000 just to replace the controller, so I decided to retrofit it myself for a fraction of the cost. If you have any questions I'll do my best to answer them in the comments below.

Awesome solution! I have an old Wisconsin force master 12ft 100ton, I looked into buying a back gauge and was blown away by the outrageous cost. I used the motor and ball screws off an old mammogram machine and a 50$ digital readout on ebay.
Nice!!
This is fucken awesome! I’ve never had a cnc machine before. I do architectural sheet metal for beach homes. I’m about to buy my 1st cnc metal folder. I almost shit myself when I started looking into retrofitting the machines with new controllers. One company said $17k another said $24k. I was like “for that price I’ll learn electrical engineering and do it myself! “ lol. I have an old shear that I’m gonna retrofit the back gauge on. Just to see if I can do it. Pretty awesome brotha! Definitely doing it after watching this!
Definitely do it yourself and save the money man. It’s not that hard. Companies are crazy for the amount they try to charge. Thanks for the view🙏
Very nicely done! I'm looking for an old brake to add my own back stop to and I'll probably do something very similar to you with Mach! Thanks for posting this.
Great solution , being a service engineer myself , It would have been nice if you would have showed us the interfacing of the motor to the drive , the problems you might have faced regarding the torque and what decisions you had to take, nevertheless it was a great solution, Thank you .
Sure, if you're ok with losing ram control, having no home position, having to re-measure your calibration point every time, no safety circuit, no estop, no auto advance, no retract or delay, slow movements and burning motors up because you're using servo stop to hold your position and not a brake. Also assuming you have a spare laptop to dedicate to this and neither production time nor accuracy is an issue for you then sure this is a perfectly adequate solution.
Nice! I'm doing the same with a Diacro press. Also wanting to use limit switches to move to next position. Is it possible to add a retract option to move the fingers away from the part once ram reaches pinch point? I'm not savvy with Mach at all. My other CNC machines use proprietary software.
Hey that’s awesome! Yeah I’m sure that you can mess with the settings to get it to move The fingers away once the ram reaches the pinch point. You could also just get it to move when the limit switch is triggered in the down position.
You can also hinge the end of the fingers so they are allowed to move up with the metal then fall out of the way.
I know this post is a year old and you've probably already done this, but you can also use a linear scale on the ram - and set the point where the die begins pinching the material. Then program the gauge to retract, then the distance the ram needs to come down to complete the bend. With 3 axes on the back stop you can program them to move up and down as well as expand and narrow for different die heights and bend widths.
Amazing!
Thanks 🙏
This can be done with plc and hmi to be industrial level.
C'mon mate. You've got to give more details than that.
cool
What's the name of retrofit kit? Is it possible to program bacgauge to move faster? Looks like it is moving slow. Also is it possible to add more servo?
It’s not a kit. I built it myself. Yes it will go faster and you can add ad many servos as you want
@@rlcustoms The more i work with my old cnc system that was made 50 years ago... More i remember this video. I think I want to retrofit system like this. Can you make more detailed video how to set up Mach3, how to use Mach3 for cnc bending machines.
@@rlcustoms Literally you only have a video of any solution for under 5000 bucks. And you only video on using the Mach3 system for cnc folding machines. You should make more video about this
@@jvjv9451 I know it. I can’t believe no one else has done this.
@@jvjv9451 it’s literally just using G code to move the backgauge where you want. If you look up mock three videos there’s tons of info in it
I need a vmc machine
can you upload a parts list?
I don’t have one unfortunately because I used some of the existing parts from the old press. But I used a nema 23 stepper motor and driver for the motion part
Which driver did you use. I'm trying to do the same thing to my Cincinnati 135 ton press
