    Aluminium Machine Bed

    Hi

    I'm building another CNC machine and want to put an aluminium bed on it using something like 15180 extrusion. However, I cannot find a supplier anywhere in Australia and have tried to organise it through some Chinese suppliers but there are so many dodgy operations over there, I'm not confident in outlaying substantial dollars if I'm likely to get caught out.

    Does anyone have any ideas about RELIABLE suppliers of machine bed extrusion?

    Cheers

    What about starting with a solid piece of aluminum plate and cutting your own T-slots in it? That would be better than a series of pieces of aluminum extrusion lying next to each other.

    Solid plate is too expensive here and I've been caught out before with plate that is not completely flat. Cutting the T slots would be problematic too.

    What is the use case Geoff?

    I made up a T slot bed out of multiple extrusions in the past. Ended up being a pain because you don't want to cut straight onto it....

    Now I just use sacrificial MDF and much easier.

    MDF with T track in it?

    This is the fourth CNC machine I've built. I want the T slot bed to make it easier to fix various jigs, including vacuum pucks, rotary axis, etc. The jigs incorporate their own spoilboards, so no danger of damaging the bed. I've been using mdf spoilboards for years, but, for this machine I want the t slot bed as the mdf bed is a pain with the jigs I use.

    Since posting this thread I have found a Chinese supplier who is said to be reliable and reasonably priced. Despite the slow shipping It may be worth the risk. Something to think about.

    Hi Zvonkorp

    Yes I had a look at Mizumi but their shipping costs place them well outside the ballpark.

    I have found a supplier from China and have placed an order. Just have to play the waiting game now to see how it turns out.

    Thanks everyone for your ideas.

    Cheers

    I was looking at Ali extrusion a while ago and was overwelmed by the options and emails from suppliers.......

    I used Aliexpress and purchased from a store called "Dreamer Hunting Store".

    It may be that I'm dreaming and the deal could be a flop but it remains to be seen. I didn't just accept the price and shipping cost as per their listing but contacted them and negotiated a deal. If the deal is successful I'll let everyone know as they hava a lot of gear in that store. I'll also let you lknow if it fails.

    Cheers

    I have found most Aliex sellers don't come down much unless you can bulk up your order, their freight is usually on the edge. Its too bad sellers don't have a logistics agent here for heavy stuff like bed plates.

    I have a design for 20x150mm(5mm thick) extrusion that I intended to make from 6061, but au has a big tariff from cn on aluminum extrusions. I could have got them made into a table kit with frame & fasteners.
    Talking to some local mills they would not make my design from 6061 as they could not guarantee the dimensional finish in the T-slots.
    Looking at 6106 alloy, its better than 6063 which most bed plates are made from. Startup costs are a lot higher from local suppliers.
    The bedplate is intended for small to medium sized machine, but it really depends how much frame support is under the plates & intended use as to the table size
