Discussion on "Machine tool development with special reference to the use of carbide tools and hydraulic mechanisms" at the Luton Section of the Institution

I have pleasure in thanking Mr. Scaife for this interesting paper. I feel sure that we have all taken in a great deal of it, although it is impossible to take all of it in. There is one point wThich I should like cleared up. I think Mr. Scaife said that hydraulic drives were not good for the main drive of a machine. Modern developments in variable speed hydraulic motors are tending towards the provision of complete and variable hydraulic control.
