Visitors to the W/S facility were always fascinated to see the manner in which the bedways of the saddle type turret lathes were ground.
After induction hardening of the way surfaces on a converted planer mill (after the rough machining of the bed ways) the bed was placed upon a planer mill which had been converted to a grinder by the addition of added coolant supply, grinding spindles, etc. The bed was carefully leveled and supported on three points. First grinding passes were at slow feeds with little stock removal, to hold down temperature and thereby avoid any distortion. Final passes were made with a different grinding wheel and employed a technique that left a surface finish capable of supporting a film of oil, for longer bed way life.
