Gwynedd Manufacturing, out of North Wales, Pennsylvania, has purchased a C & B Machinery 36” Swing Arm Double Disc Grinder to grind some of their Abraham & Moses Survival Equipment knife blades. These steel and powdered metal knife blades will go through a rough grind and finish grind. With other operations being performed between the two double disc grinding operations.
These knife blades, up to 11″ in length, have a rough size tolerance of ±.0015”, parallel tolerance of .003” and a surface finish of 32Ra. The finish size tolerance is ±.001”, parallel tolerance of .003” and a surface finish of 32Ra. The total stock removal from raw blade to rough size is .045” to .050”. Stock removal from rough size to finish size is .004”. Gwynedd Manufacturing plans to start production with these blades but also has plans to grind several other parts on this very versatile grinder. The simplicity of our Swing Arm grinding machine is conducive for quick changeovers from different part types with low tooling costs.
