BK Mikro Tool Break Detection

[Machinerer]

Has anyone used this style of tool break detection? How did you like it? Pro's/Con's? We aren't worried about actually setting tools as we have a Zoller Presetter, so a laser is overkill.

I've only used the Contact setters from Renishaw, and lasers.

Broken Tool Detection Systems for Harshest Machining Environment

Broken tool detection systems are designed to the highest standards for automated production process.

Haven't used one, but it looks super trick!

The cycle time savings of in-machine break check vs in-magazine break check I imagine it would pay for itself real quick.

Another option is optical tool break detection. I think DMG-MORE$$ has that as an option these days.

We have lasers on a few of our machines. Is that what you're referring to when you say optical? Or is there something else?

Are you considering the type that is designed for checking the tool in the ATC, and not inside the machine?

I have one of these in a machine: https://www.alloraintl.com/positive-contact-tool-sensors/standard-pcs-tool-sensors/pcs-100-system/

Call it up to an area and fire it. similar to how you would position and run a laser or tool presetter.. It is hooked up to an m-code that fires it. if it fails (swings past broken tool), the m-code doesn't finish and a red light turns on (not setup for a true alarm)


However, I have a newer horizontal that I would love to have tool breakage checker added to the ATC side of things. But that is more complicated.

If you get one, let us know how it works out and how to interface it. I am worried it would require a ladder edit.

I believe I've seen a video that has a camera with flash take a picture of a tool before and after use, and compares. Maybe it was dmg?

I installed several MARPOSS TOOL BREAKAGE DETECTOR. Contrary to standard laser systems, this is very easy to install. Quick and reliable. This MARPOSS TBD TEST shows the actual installation in action.

I am not opposed to any style. I just know that lasers, and Renishaw units are overkill, as we don't need anything for checking length.

Thank you. I'll contact them for a quote as well.

I have used "the whip" on DMG MORI Duoblocks before. Worked great. Checks the tool on the way out, then checks it again on the way back in. For a simple pass/fail, they are fast and effective. The resolution is not very high, so I don't think it would work great for micro tools or tools that might get damaged instead of break off. But if you have a laser in the machining envelope too, then you get the best of both worlds.

Not sure why more builders don't offer that option. Was shopping for a five axis cell some years back, and a couple of the super premium brands got upset with me when I asked.

That is fun.

Years ago I saw a camera system on FANUC Robodrills that could do a pass/fail tool check without even slowing down the turret head. Can't seem to find a video of it now. I think that might be what Dan is remembering as well.

We used "the whip" on my previous job, while working on Wattsan, and it performed excellent
