Attempting MONSTER 1.0” DEEP Cut on the BLOHM Surface Grinder

[@johndennis3181]

I don't do much grinding but when I do and take a .0005 cut (no coolant) I feel like I'm going deep...

[@NonsenseTreasure]

Idk, I've never ground less than 0.01 mm at a time, and that's on a pretty much toy-grinder

[@phillhuddleston9445]

@@NonsenseTreasure Depends on the accuracy you are after. If you are doing a one off part or a few parts and you start with .005" that needs to come off you may leave .0005 and work a little off at a time if you are trying to hold a total tolerance of .0001" or .0002". If you are grinding mainly for a surface finish it's a different story.

[@graealex]

That's probably because there is no need to go deeper anyway. The typical depth of cut would at max be defined by the amount of shrinkage/deformation from heat treatment. Taking off a lot of material with grinding is stupid, as it causes a lot of heat in the part.

[@MawoDuffer]

The deepest I go is usually .002 inch but that’s only for roughing.

[@kingkowala]

[@doyletech623]

As a CNC grinder that blow my mind I have never took took more than .025 per pass on a punch and die set for a punch press and never seen a form grind hold up with out a over head dresser or single point dresser . these new machines can do so much more than the older ones ever thought of doing . Very impressive thanks

Heck, I'm amazed they're able to put out all the videos they do.

[@jclay6680]

I remember once a worker used a 20" diameter grinding wheel machine ( non cnc ) and took too much off in one pass , and the wheel exploded .

[@phillhuddleston9445]

I've had a 12" wheel catch and pull a tall part that was being held by blocking into it explode and send the part across the aisle and the blocking into the sheet steel stop plate puncturing a small hole in it. By the time you realize something happened everything is already done, you will not see parts and wheel pieces fly, this was around a ten pound part and it was like a magic trick, it just disappeared.

[@importantdolphin8974]

that's because the wheel is not a creep feed wheel like Titan is using that can take off a lot of metal in just 1 pass. the one you're using is not designed for heavy depths of cuts

[@valeracnc2752]

Very cool!!! could you tell or show in more detail about your emulsion and cooling system through your custom coolant bracket? it seems to me that in this type of work it is very important that the cooling emulsion under high pressure wash the grinding wheel, I just wish I could do something similar for my grinding machine...

[@joe-lflores109]

[@RippenSXS]

Hey my comment made the video! Lol. That's cool that it can do that. Can it do that repeatedly like for production? Seems like someone needs to be there to watch the load. Or can it be programmed to slow down when load hits 90% or something?

[@UnitedGrinding]

Yes, the machine can be programmed to adapt feed rate to a set spindle load.

Titan - MODERATE

[@Alexserio]

what is the grinding wheel specification? And what parameters have you driven cutting speed, infeed, metal removal rate, feed rate?

[@Qusin111]

so feed rate was what 0.5" per minute? what was the surface finish for end to end?

[@jerryjohns1]

1 inch deep club for life

[@accumulator4825]

Chill everyone, this is just for fun! And it was haha

[@rickiee54]

What’s the infeed rate ipm?

so... one inch on a beveled wheel? kinda cheapens the effect

[@Turboy65]

I have a grinding project for you. Make a knife with a full hollow ground edge and grind that edge, the whole profile, on this grinder and do it in one pass per side. Then do a second finishing pass for maximum surface finish quality and a very fine edge right out of the machine.

[@bigskyhobbycorner603]

I want to see some rough out lathe work on some 10 inch inconel 625

[@phillhuddleston9445]

Just because you can do something does not mean it's practical to do so but this was interesting.

[@johnjennings8085]

Why would you need to that heavy of a cut? Is this a normal thing or just showing off? Don't you want to mill off more before grinding? Please educate me.

[@tylerakerfeldt7220]

Wouldn’t the angle on the wheel increase the overall cut surface area?

[@bluustreak6578]

Yup, I'd say so

[@phillhuddleston9445]

Yes but the total material amount removed would be less, still more tool pressure after obtaining full depth.

[@jackmclane1826]

Just because it's possible doesn't mean it's a good idea. Splitting that into multiple cuts would probably be faster. The large contact area makes a lot of friction filled with swarf, that does not remove significant material.

Someone tried much less on a surface grinder at school once.... ...and it went bang. Teacher wasn't happy.

[@mehmettemel8725]

I know it's out of context of this video but wondering if you guys always thread mill in Ti 64 or use a tap as well.I tried to tap some holes M16 only about 0.5 inch deep and snapped a fine grain coated tap on the 6th hole.Didn't have a threadmill the right size and didn't have time to order one.Worst of all couldn't tap it by hand either even though I used through coolant drill to minimize work hardening.Any info would be greatly appreciated.

[@urgamecshk]

Drill or mill to 65% thread form. Keep tap rpm under 12sfm. Peck 1/2" D Max. Use rapid tap

[@bluustreak6578]

Impressively little wear on the wheel for sure

[@garythegreat8629]

That is literally insane. Any specific reason you used and angle and not just a flat dress?? My initial thought is so that it works its way into the cut instead of all the surface contact at once.

[@jmowreader9555]

My thought is to answer questions about wheel wear patterns. If they would have flat dressed the wheel, it would have been hard to tell uneven wear across the wheel in the final cut. With the angles they dressed into the wheel, edge roundoff will pop right out on the cut.

[@zengineeringmy9088]

Awesome..👍🏻👍🏻👍🏻👍🏻👍🏻

[@steveunknown8407]

I commented this a while back but I don't think anybody read my comment, put a thermal imaging scope in front of your camera, it would be really great for safety and observational reasons.

I read it, and i like the idea. We are currently experimenting with some different ideas!

[@hereticswissery9010]

so 1 inch a the top of the angle right not at the bottom? :P

[@Jatsekusama]

It's impresive but i don't know how i feel about it. On one hand it eliminates a lot of setup and milling work but on the other it looks like it's not sustainable in the long run and it looks like huge fire hazard Edit: it appears i'm in the wrong here :) I guess you learn your whole life, thanks for clarifying in the comments :)

[@Spoteddy]

thats not a cut, its a grind...

[@CrazyHorse151]

Isn't that kinda misleading? The depth doesn't really matter but how much surface is being cut at any time. And then, it depends on the feed speed as well, right? So really, the depth will lead to a higher surface area in contact with the wheel but that "1 inch" doesn't really say much. Depends on the wheel radius, the profile you cut, the width etc.
