Numerical control is increasingly being used in the workshops of British Rail Engineering Ltd, to overcome batch production problems and shortages of skilled labor. A new long-bed CNC lathe by Churchill completes all the turning on long axle shafts for locomotive wheels in approximately 26 percent of the time previously needed. A Churchill NC chucking lathe is used to machine steel castings with weights of 356 kg, and heavier. Drive is automatically shut down if the spindle speed exceeds a safe level. In the machining of railway axle boxes, ability to precision bore large-diameter deep holes is the dominant criterion, and a Herbert DeVlieg Jigmil with CNC has been chosen by Crewe Works for the task. For refurbishing major items, including large diesel engines, a large-capacity Maxi Check computer-controlled measuring machine is used to check items at the premachining stage. Features which need to be remachined, and by how much, are rapidly identified.
