Huh that fixture table looks expensiveeeee and I bet those Jigs weren't done on a Diy build. . Lol

What coating did you put on those nice shiny tooling plate jigs.?

At this time , being honest and because i have been told to keep it on the downlow unfortunately not the jigs are made for the bike manufacturer im working for ,no leaks, but i will post some for you when i get given the secrets out

Hey Jazz its an optical alignment table your quite correct , they were done on a hurco

I am designing some cnc controlled fixtures and machinery though for the shop but without an industrial cnc its kind of hard to make them

Its simply hard ano with a coating called marbocoat applied after to stop epoxy and the like adhering

Do you mind revealing what cutters you used to get the seemingly good finish?

i use the aluminium specific WNT milling cutters any aluminium specific cutter will give you a pretty nice ,they eat material though you have to be careful at your ramp in when side milling as they like to take a big bite they supply the place i used to work AMRC | The University of Sheffield Advanced Manufacturing Research Centre with Boeing (http://www.amrc.co.uk/) the fancy finish on the tooling plate is just standard mic 6 the actual face mill they use is a PCD insert on a 1.6m dia face mill ,

Is the jig for assembly/bonding carbon fiber components, will the bikes be made in the UK.

Jon that finish is easy to get.? . . . . All you need is 80,000 and flood cooling that blows lady's knickers off. . Lol

that will be flood coolant at 1200 quid a barrel thank you... but your right half the time ruining finishes on allly is when the chip cets recut or swarf gets pulled in from another area

Thanks for the info - I was just interested to see if you'd done it with a cheap tool, or HSS not carbide.

I know, I've got finishes like that consistently when I've used good new tools and flood coolant, but an expensive strong machine certainly helps.

Mmmmmm marbocoat! cant beat the stink of a decent semi mould release. And quite scary to use when you're used to wax/pva.

I guess the cat's out of the bag? We have a few Hurcos in work including a VMX with trunnion table for 5 axis work, nice machines.

Great to see inventive British manufacturing back on the scene. And in Penistone, one of the best places to cycle as well, used to do a lot there pre-accident.
