Hi Guys
There's surely some of U learned and experienced Folks out here who would be able to recommend a Type and Source for blades to cut CARBON FIBRE. ?We do have a large Vertical Metal Cutting Bandsaw whose Blades are literally destroyed whilst Cutting this difficult material.
Would immensely appreciate some input from U Gents
TIA

Hi ARM You need a carbide grit blade.? It specially made for exactly what you're doing,? Its for materials that abrades rather than form chips, like ceramic and GRP, CF etc. Also use to cut up rubber tyres where they have to grind through the steel cords and rubber at same time. I know they're?made in 1/2" wide as continuous grit, segmented grit (where grit is plated to the blade in segments with uncoated but full blade width sections between) or gulleted whether there's a gullet between the coated segments. Don't know about other blade widths but expect they're probably available too. I don't think there are different grit sizes, but the continuous, segmented and gulleted are increasing aggressiveness?of cut,? so act like increasing coarseness TPI on toothed blades. Hope that helps - jv ?

Yes indeed that helps a stack
Much appreciate the prompt and comprehensive response
Now will proceed sourcing this?
Thanks a zillion once again

Sorry T C, didn't think about where you'd get them. Morse offer a range of medium and medium-coarse grit blades?both continuous and gulleted in the US in 3/8" and 1/2" wide. Snapon who own the Swedish company Bahco have carbide grit blades too, but I'm not sure if they offer them in the US. I see in the Snapon 'Bandsaws and metal cutting tools" catalogue they offer?1/4" wide gulleted fine grit and 3/8"? medium and medium-coarse gulleted only blades.? They only offer 1 continuous gritted blade grit in 1/2" (medium grit) along with?gulleted? medium and medium-coarse.?? I thought gulleted blades would be be too aggressive, but if the only fine grit blade offered is gulleted and the narrow 1/4" and 3/8"blades are only offered in gulleted too, then maybe gulleted is OK for finer work like a knifemaker would do. Let us know what you get and how they work, I'd be real interested and maybe other people would see options they didn't know about. Rgds - jv?

Carbide tipped blade for solid composites & carbide grit blade for hollow shapes.?

What about diamond coated blades, do they exist? I know they do for circular saws (I recently had to buy one because I was cutting an epoxy counter top which literally turned a fresh carbide blade into scrap in about 7" of cutting- the carbide bits were worn into little "L"s!)

Dave,
?Diamond blades certainly exist, but I'm not sure how well they would do in this application. I use several saws for slicing rocks for jewelry that range from 24" blade down to a 4" blade that I rarely use. All of my saws run wet with either water or oil, and that may be a problem for the carbon fibre. ARM, if you're reading this, I'd be glad to do a sample cut on a small piece with a diamond blade. Let me know if that's anything of interest and we'll set something up.?

Whether or not you can use any kind of coolant will depend on whether the customer has any manufacturing specifications restricting it's use on the part. Never used anything but regular coolant used for mills, saws, grinders & belt sanders on cured composites. Part applications were for space, aviation, oil industry, sports equip ect...?

Hi Elroy You're speaking from experience with carbide toothed blades on a bandsaw.?? I can see a grit blade working on a 4x6 no problem, but
I've always thought that the 4x6 wasn't rigid enough,that they would vibrate too badly, esp in the guides, to use a carbide?toothed blade.? What sort of bandsaw are you using the carbide toothed blade on???
Do you have slipper guides or roller guides?? What materials do you cut with?them? Do you have to do anything special to make them work? What problems have you had with them? Thx - jv

I'm not sure about the size/thickness of material needing to be cut, but another option to consider is a wet tile saw.? The blades usually are diamond.? You can buy diamond tile saw blades for $14 on up depending on the vendor and diameter, if you want to roll your own.....but a new SKIL tile saw only will cost you a bit over $100 (Amazon price) and it comes with a 7" saw blade.

I used these blades on a Kalamazoo swivel head? & a hydraulic power feed DoAll with slipper guides, which worked exceptionally well. The Kala had rollers, both cut reliably & I didn't have issues with either. You're? right a 4 x 6 might shudder with a carbide grit blade but if thats what you have on hand I think you should be able to get thru as long as the the job is not oversized for the machine. Cut mostly carbon fiber & some fiberglass composites. Nothing special just run coolant when possible & once you get started cutting initially you will eventually work your way to the settings that work best for you. These materials are severely aggressive on the blades but they gave good service life & you just have to accept the fact that they will die sooner than cutting metals. A good bi metal blade for metals is the ticket also.

Thanks Elroy. Does the job shudder worse with grit?than teeth? or was that a mistake? (The teeth are more periodic than the the grit so I expected teeth to be worse for shuddering) Industrial?bandsaws are much more rigid than our 4x6's so not surprising that either of these blades work well on them. May well be that TC has an industrial saw too and he'll be ok with either - jv

The grit blade causes more resistance in the kerf especially when the carbide grit starts to wear & get dull. Keep the feed at a reasonable rate & both with cut well for you. Carbide tooth for solids & carbide grit for hollow shapes will do you just fine. btw there is no "r" in my first name, no biggie common mistake. Hope the info helps.

No worries trust me 99% of the time that's what people see. Mandela effect maybe : ) glad I could be of service, I love all the little tune ups we do to our equipment. Have a great weekend.
