Hello Ladies and Gentlemen this is my first post.
Can anyone tell me who is the best supplier of ball screws and nuts. I want to buy online so I need prices and dimensions of the nut displayed.
Also how machineable are ball screws ? Are they too hard to machine on my Myford ML10 or ML7 or do I need a cylindrical grinder !!
Also I am going to have a crack at retrofitting CNC to a Chester tools Champion 16v milling machine ( link here http://www.chesteruk.net/store/champ...speed_mill.htm )
I need an idea of roughly what torque I would need for the stpeer motors on the x y and z axis ?
I think 4Nm on the x and y and 6Nm on the z because of reference to this machine which is a similar size and type. ( link here http://www.arceurotrade.co.uk/Catalo...Hobby-CNC-Mill )
Any help most appreciated
Kindest regards
Nick
