Hi guys, i want to purchase a few parts from BST AUTOMATION. I purchased a few years ago some linear guides like
but read bad things about it for aluminium machining :)
I want to build an machine with rigid Y axis and move just X table (think that is easy to get rigid machine with small X and big fixed Y).
Want routing surface of 600/800mm Y and maybe 300/400mm X.
Want some small machine because want high rigidity at least for make parts for bigger machine.
Want to route at least aluminium/copper.
Will be OK purchase HGR25 ones ? if purchase HGR35 will get the same result?
I have a lot of questions but will start with this one :)
PS: have two 16 (600mm) and two 25mm diameter balls crews (1000mmL) at homeLast edited by samsagaz; 03-06-2016 at 06:24 AM.

Its possible to route aluminium with these I have hgr20 on my build around same size as you plan ( http://www.mycncuk.com/threads/9678-...-Framed-Router ) , and cut aluminium regularly without problems, the general advice I am sure will be go for more expensive square rails which are indeed better at a price, when I sell up and move and get a proper workshop I may well build second machine and use top materials but for first build I am happy with performance of these and the price.

20mm rails will be more than enough for a machine the size you are building...Clive

Hi Samsagas
Welcome to the forum
As Clive sail 20mm Hiwin rails more than adequate.
Under no circumstances purchase any electrical kit, get a design knocked up, show it to the lads and they will give you advise on the best option for motors and drives.
Good luck with your build
Regards
Mike

so 20mm is more than enough, great! can purchase long ones then to use more of my ballscrew.
Btw, when is needed 25, 35, 45mm ones? exist some kind of relation table?

25mm + rails would be for industrial machining centres where they are chasing max stiffness high throughput and long hours. But the cost goes up with the bigger sizes and the money would be better spent on the other parts to keep it all in balance.

i already start the draws! i really liked designs like Silyavski design https://www.youtube.com/watch?v=C9hTLN1CydU (low profile and moving grantry) or fixed gantry like https://www.youtube.com/watch?v=K9UA9ZRFwWU
These are very good machines i think, and maybe impossible to make for myself but will try to draw something :D
I will use welded construction materials like IPN and UPN ones.
will try to draw two designs to see wich recommend me
