where to get aluminium plates cut and drilled

[reefy86]

thanks again guy's, the shape of the z axis plates are quite plain and simple its just the holes that need cutting out for the spindles and all the m10 and m8 bolts, the plates are 25mm thick and the 3 plates that the spindle sits in are 15mm.

cheers

Do you not think that this is OTT I think you will have difficulty in finding someone to drill into the ends of plates to the accuracy that will be needed to put this together. Then you have to think about maintenance .
Please don't take offence it's just my two pence worth.

no offence taken im here for advice and most important for my benefit "criticism" :) ill go back to the drawing board then to figure an easier way to bolt this together.

i think maybe if i just got all the plates cut to size and all face sides drilled and tapped by experienced people then when it comes to the edge of the plates i can align all the plates together and mark out the holes from the plates and then just clamp and drill my self using a decent pillar drill. the plates are 25mm thick so plenty of space for 10mm bolts.

unless anyone has a better idea :)

As Clive said getting the tapped holes in the edge of the plate will be a mare.
It needs to be set up on a mill,clocked in and drilled using digital readout then a couple of dowels after its all squared up. so your back to a machine shop or one of the nice guys on the forum.

Or alternately get a nice member on here (or make yourself) one like Wal had made for drilling and tapping into the end/side of the plates....http://www.mycncuk.com/threads/6164-...-Jig-Finished!

If i was doing the job i would also use a jig but slightly different, would make it with 2 holes with an L shape cross section, make all holes on the assembly the same pitch, so you would clamp the jig drill & tap first hole, shouldered bolt goes in that hole, do second hole, move jig down using the shouldered bolt in the second hole drill & tap third hole in so on, the jig can also be used on the clear holes.

Hi reefy,

For marking out the edge holes - although I've not used one, I've often thought about buying transfer or universal punches in case I needed to transfer holes:

With the holes drilled in the top surface of one plate you would align it to the edge of the other (using clamps, 90 degree blocks etc.) put the correct punch into the hole and 'transfer' the centre point onto the edge surface.

This is exactly how I would go about it, if you take your time you could drill and tap yourself, just take your time, especially when tapping and I think you'll be suprised how easy it is.
