    Default How much will this cost to cut?

    Hey Guys, I'm thinking about converting my latest motorcycle from a dirt bike to a "supermoto" i have done it before but never completed the process to 100% as i ended up selling the bikes and wheels

    i'm wondering what should i pay or what is a reasonable amount i should pay to have this DXF file cut from 4mm steel or even stainless steel? it' a motorcycle wheel adapter for the disc brakes

    here area couple of pic's from my previous attempts







    the DXF file is here http://motard-supermoto-wheels.sport...pter-plate.dxf

    this is the bike i want to convert now

    I can't access the file, but something that size would have to come in under fifty dollars.. I've found it worth while to send out the dxf to local laser cutters for quoting.. Maybe six or seven. Then you can choose. There are no shortages of laser cutters here in Victoria, so it's a very competitive industry. But in saying that, quotes can vary considerably though. My last laser cutting job quotes varied over 100 percent from the cheapest to the most expensive.

    Thanks Gestalt, would laser jet be better over water jet?

    Id prefer water cutting, no burr or hardened scale to worry about. Your .dxf comes up in my program as being in inches (as in, its 155in across) and im betting thats in error. Also, id ditch the holes and replace them with some very small pilot holes, that way you can drill them more precisely to suit your needs and you wont have to worry about any draft on the cuts on the holes. In any event, that part should cost around 20 to 30 bucks, depending on who is doing it and what metal youre using / theyre supplying. Thats an ok solution, not great though.

    A better solution is to get yourself one of these. Lets face it, its got brembos and the ladies love the brembos. And stoppies. Or get yourself a Speed Triple. It does the stoppies and the wheelies thanks to its million, zillion horsepower. You know you want to!

    Last time I was here and attempted to point out the commercial aspects of the Industry, I got black banned for 2 weeks.

    You do know a machine capable of cutting 4mm in Stainless commercially will be 2Kw +. Minimum buy in price of half a million bucks. And any one you send a DXF to, will run it through their CAM, to come up with a quote. Your doing that 6 or 7 times? At 5 minutes each quote, you just wasted 35 minutes.

    Largest percentage of Laser Cutting Companies I attend, blanket ban quoting on motor cycle disc's, or exhaust manifold flanges, for that reason.

    Regards Phil.

    Scott.

    Where are you blokes getting that done for $20 -$30 bucks? As a one off, Material included.

    Water jet is nearly as inefficient as laser. At 4mm it wont be water, that will need abrasive. Ubber power to get that 60k, psi + garnet + wear on the nozzles. I'm told you cant break even out of those sub $160 per hour.

    Quoting on potential jobs is standard practice Phil. If companies don't wish to participate they simply don't reply with a quote. They are not to know what the component is to be used for and certainly wouldn't pass judgement on that. I've found that maybe one out of ten don't reply.

    Gazza before you get it quoted, fix the drawing. Every "circle" is slightly out of round and none of them are circles, they are all spline curves. Make life easier for the CAM bloke and maybe cheaper for you!

    I don't have a DXF program to open the file it just reads all numbers on my screen, can someone with the correct program possibly screen shot a pic and upload it?

    Stainless would be ideal but not necessary steel will be sufficient

    i had sent off over 5 emails the other day to online laser cutting companies all around Australia found on Gumtree, 1 guy had the decency to reply, we sent emails back and forth untill he mentioned he doesn't have 5mm thick material (i thought i needed 5mm) but it's actually 4mm i lost the guys email thought i had it saved

    i was checking out the Gumtree add's than looking on the Companies web site, most i contacted said "no job to small" or along those lines so i sent off the emails with the DXF file as an attachment

    Seriously? They open a DXF showing the outline, and they cant tell it's a disk brake? This New MetalWork forum, thing seem's to be really working.

    That's not what you said.
    My last laser cutting job quotes varied over 100 percent from the cheapest to the most expensive.
    Did you try NewTouch Laser, Bayswater. The Industry leaders, Customer of mine. They have 3 blokes in sales attached to each machine, 60 -70k$ per year writing quote's for bloke's like you.

    You're kidding your self. I spent 12 years under the same roof as Australia's largest Australian owed laser manufacturer.
    Linky poo>>>>BLS Laser

    If you have an old yellow pages pre 2010, you will find my company address and there's are the same.

    As I said, largest percentage of laser companies I attend. Knock that quote out of the park. I'm relocating a $1m Baykel, 4Kw Rofin Sinar. 16th June, Bayswater. Come down and argue with me.

    Adelaide is the worst for it. Every sixth laser enquiry if for an exhaust flange. It never amasses me when I'm over there working. You can't walk past a dispatch bench without an exhaust flange sitting on it.

    OMG. I'm working with the wood heater guy here?

    I'll check in again about Christmas time, just incase a metal working discussion breaks out

    I don't have any experience with having water jet cutting done Gazza, but as it was pointed out by scottyd, there is no heat affected zone when water jet cutting. Not that that would be a problem for a spacer.

    That's right Phil. They are in no position to judge or guess what the component is to be used for. Even if the file was titled "disc brake" it would be meaningless to these companies. It could be for an industrial process for all they know. It's totally none of their concern and not their responsibility and they could not care less.

    Seems you're trying to play judge, jury and executioner!!!

    Seems you have some real issues going on here. The industry is what it is and that's how it is Phil. I don't think you've got a good as a grasp on the industry as you think you have. Not taking quotes seriously would be a big problem for most laser cutters, and engineering companies in general. Do you honestly expect a company or individual to send off a file and say "cut ex amount of these" without getting pricing!!!! Especially if it's the first time in dealing with the said company.

    A mob up here called Midwest Conveyer Belts, they have done a bunch of flywheels for my kid's V twin wobblers at 27 bucks a pop. Theyre about as complex / similar size. Our wheels are 16mm MS plate, not 4mm SS and I might be skewed price wise with the stainless because the stuff grows on trees up here in wine country...but if I was to get these guys to cut one up, id be in the ballpark.

    I know everyone's afraid of the phone nowadays, or heaven forbid, face to face contact, but you might find that more productive than sending out multiple emails - to often, small companies. From memory, you're out west, I'd try Grant out at Northwest laser Mulgrave if you want stainless or Wayne at Intricate Engineering Windsor for mild and water jetting, they've always done right by me...but there's hardly a shortage of laser cutters in the metro area. Might be an idea to provide the material too, rather than hope they have an offcut laying around...and point out you think the drawing might be suspect.

    Gazza, I had 6 of these cut recently. They are 304 stainless 3mm thick and cost $12.00 each including material.
