What should i expect to pay for these two parts?

[gazza2009au]

Hey Guys

I hae no clue when it comes to CNC/Laser Cutting, What should i expect to pay to get one of each of these made first one from 4mm steel (roughly 150x150mm) second one 6mm steel (roughly 120x50mm) trying to find a local shop sent off one email but they can't reply untill monday thats almost a week away crazy...

I haven't checked lately, but a couple of years ago the local laser cutting place had a minimum order of $100
Mate of mine had a bunch of caliper brackets laser cut for landrover disc brake conversions (approx 150x100x16mm for the main bracket, and 150x75x6 for the spacers). He was selling a set (2 of each) for $100 so I'd estimate his material and cutting costs were less than $50 a set.

Thanks Steve, I would have just paid the minimum for one set without knowing, i may ask about doing multiple sets

can anyone recommend a good company which uses quality steel and can take a email/over the phone credit card order in Oz?

Can't help with recommendations, wrong state for me, and too long since I had anything done.

There are three components to the cost base, material cost, machine time including setup time (locating appropriate stock, loading it into machine magazine, actual run time for the job, recovering/sorting parts from cutter, and discharging remainder of the stock), and job programming time.

You can't eliminate job programming time, no matter how you present the design info to them, they will have specific profiles for their machine and the control codes will be generated that way. Maybe if you supply a decent DXF of the layout, they can import that into their layout software and do a minimum amount of markup then convert to G code, but their will be some cost. If you are sure of the design and will want multiples, let them know because it is easy for them to do a step and repeat array prior to generating the code. This reduces programming time per part significantly. It's also helpful if you can make the job a 'when you can do it' type rather than a rush job, as they can incorporate your job with another part sheet job using the same material prior to conversion and eliminate a set machine loading/unloading from the combined jobs.

Material cost will include the material returned to you plus the material wasted, typically for the disk design in the first pic, a batch of these would be in the order of 60-80% utilisation depending on their machine profiles (how close together they are willing to allow cuts). They would most likely strike a straight cut beyond your area of the sheet to facilitate storing the part sheet and repositioning it on the cutter for later use. You can expect that they will charge for that material as well.

There is no real indication of what these parts are for, or what processing may be needed when you get them back from the cutter. But be warned, the material will most likely have dags from cutting along all cut paths, and will be as hard as hobbs around them as well, due to local heating. If you need a truly clean cut without variation in hardness, maybe you should be looking for a water jet cutter instead.

Hey Malb all that setting up doesn't sound cheap, the disc is a spacer for a motorcycle wheel to adapt a different model bikes brake disc to the wheel, the second one is a brake caliper relocator for the above mentioned disc

its for putting Honda CBR250R and CBR250RR road bike wheels on a Yamaha WR450F

this is why i bought the lathe because its so hard to find anyone who will machine the wheel spacers i was quoted over $500 for a Chinese company to the wheel spacer machining from memory and a local shop wanted i think $1200, i was told $2500 would be right for a full conversion by a motorcycle engineering company that is more than the bike pictured cost

[Com_VC]

Are these parts just a one off or do you plan to make more in the future?

Do they need to be made from mild steel or could aluminium be used instead?

Do they need to be 4mm and 6mm in thickness or can this be increased?

[gazza2009au]

Hey Com, I will likely make more down the track and yeah they need to be made from steel for the strength of front brakes on a motorcycle possibly doing 110kph and having to come to a complete stop, they also have to be 4 and 6mm due to clearances

You are aware you could make the parts in less that a week using hand tools ? A rule ,a pair of dividers, centre punch and a file or a grinder, a drill or better a drill press and some drill bits, or if you print of the drawing use it as a template to center punch through you don’t even need the rule or dividers.

I could probably make the disc adapter on the lathe but the caliper relocator i would need made so i'd rather just get both made at the same time, if its anymore than $100 i'll just have to cry lol

The second calliper re-locator I reckon could be made by
- drilling out the internal radii or concave/ inflection points with a DP
- rough cutting with an angle grinder with thin kerf cut off wheel
- grinding/sanding.

In my shed I would start by drilling out the internal radii as described above and the either Plasma cut or bandsaw cut and then use a linisher.

The local laser cutter sent me an email today saying he will send a quote in the morning

[gazza2009au]

Holly molly was quoted $231 for the two parts

[BobL]

Ouch.This reminds me a bit of the cost of purchasing a piece of Al ~350 x 350 x 12 mm.

The quote I got was $95, $70 of which was the cutting fee, because for >10mm Al plate they could not use a guillotine and had to use an automated cutting machine and $70 was a minimum charge for programming the machine. So I bought ~350 x 1200 x 10 mm, cut with a guillotine for $85

[gazza2009au]

At that price i just can't afford to spend that kind of money on it, it just makes the project sky rocket in price and there would be no profit after i spend 5 hours on the lathe making the wheel spacers, even as a one off project for my self that is might expensive if i were to continue and get it done for my nephews WR450F 2018 i don't think he could afford the $231

i was hopping it would be around $100 $120 and maybe i could get a second or third set for $30 more lol who was i kidding bloody hell :no:

Australian machinery or to manufacture cost a bomb

[Michael G]

Ask about multiple sets. A lot of the price is in the time to program. We used to say when making parts on our CNC machines that the first one cost, the second one was free. You might find you can get 3 sets made for not much more than one set. The steel would not be much for those parts.

Would you know if this was likely to be an ongoing conversion????
Unfortunately that the cost of business nowdays, try finding a place in China that might do the job, if you still want to go ahead with it. I'll offer to try to get it done at our cutter's place, if you can send me a PM with your email, I'll reply with mine to send the dwg file to. I can't say they'll be any cheaper or not as I don't know.
Our CNC Plasma cutter isn't set up yet, it'll take a 2400X3000X25mm sheet

[gazza2009au]

Hey Kryn, thanks for the offer another member may be able to help, i think that high price i was quoted is for the setting up the machine twice so i can understand the hefty price

[KBs PensNmore]

If you get stuck again, send me a PM??
Kryn

[gazza2009au]

Will do thanks Kryn

I am still at a loss here ,this is a drill press and an angle grinder job, yes some one could do it on a jig borer or a CNC mill, get it water jet or plasma cut, but at the end of the day ,you don’t want to pay the market price, you could have made it by now and be out on the bike doing skids

[gazza2009au]

The laser cutting company replied to my email today and said they can cut 3 sets for the $231 so works out $77 a set

They wont be consistent from one to another, they wont be tidy and they'll likely be time consuming to make, at $77 a set that works out very good happy to pay that than make them my self which would likely take a few hours

[gazza2009au]

This is a great forum very helpful and friend people here over the years i have received help by a few personally one guy spent hours machining wheel spacers twice for me and now i have a lathe i know exactly how time consuming they are to make... you may think a wheel spacer 5min job but stopping and starting than trying to get down to exact 00.05mm it easily eats into the hours making up a kit

than the bloke helping me now with the disc adapter and brake relocating bracket's bloody ripper :2tsup: got them next to nothing money wise

hadn't realized how much laser jetting and the like cost i thought it would be pretty simple but seems they need a technical operator to program and that in its self cost all the money, i think that is why i was quoted $231 job was $210 + GST lot of that coin would have gone into the labor, Shops usually charge $100 $120 an hour in labor for most services i have never looked into what actually goes into setting up these machines but it sounds like it would be complicated

thanks to the person who said to ask about multiple pieces as if i had paid that $231 i would have paid that for each set and bought them as needed its a bit sneaky that the local laser cutter didn't even mention this to me Until i asked about it
