Exactly why we are all here,to share and learn.I have built and am continually refining a small milling machine x/300,y/200,z/50 capable of machining stainless steel.Mass is one way of obtaining rigidity and reduce deflection but
i am more interested in overcoming these problems thru structural design.If there is anyone who is interested i would be glad to share the little i have learnt.My machine is a moving head type. X axis rails are 32mm tool steel
bars and y axis rails are 20mm same material.Solid steel blocks 40mm thick support the head.I will be posting recent pics soon.In the mean time i have some pics of the first design. The machine was pneumatically assisted on all axis. All pneumatics have been removed and the head is now driven by a 300W 3 phase motor under control of an inverter with infinate speed control and slip compensation. |
