Manufacturers use grinding machines with a narrow work wheel requiring several passes to reduce the diameter and achieve acceptable surface finish. Thus creating longer cycle times. Machines are difficult to adjust for setup and changeovers requiring highly skilled technicians. Heavy material removal in a short distance deforms thin walled tubi...

To establish a process whereby pre-sintered carbide drill blanks processed in a hot isostatic press (HIP) can be pre-sized to produce straight rod stock for long blanks. The existing method of manufacture involves sintering the carbide rods in a hot isostatic press then grinding them to size in a hard state before the fluting o...
