TURBINE SPOT FACE GRINDING MACHINE
THE NEED: Customers require precision spot face grinding of coupling bolt holes. The machine should be compact, lightweight and capable of working on a wide range of coupling bore diameters and lengths.
THE CHALLENGE: Most spot facers are limited in bore diameter range as well as coupling lengths. Additionally, the tolerances commonly achievable are not as tight as is required for today’s requirements, and setup can be time-consuming.
Current lack of a machining solution capable of performing desired operations means lower productivity, requiring multiple machines for a range of workpieces. The inability to hold tight tolerance means extended time for setup and machining as well as possible rework.
THE ANSWER: One machine with small and large machining range options covering a wide range of couplings. Precision mounting collets, fine grinding wheel adjustment and simplicity of machine design provides a versatile, quick to set up and highly accurate spot face grinding solution.
- Grind spot faces of counterbores in a full range of coupling diameters and lengths.
- Capable of alignment to the centerline of finished bores.
- The face must be perpendicular to the bore.
- Mount to and grind counterbores of either assembled or separated couplings.
- Very precise counter bore axial run-out, counterbore flatness, perpendicularity of face to bore centerline and surface finish.
