DRILLING RIG MAIN SHAFT COATING

The project highlighted here exemplifies our ability to apply precision grinding and coating processes to large diameter shafts. This customer needed a phosphate coating applied to shafts with variable outside diameters of 8" to 24". Prior to coating the shafts are sand blasted, and then ground on our Landis OD Grinder, which features a 30" swing, and is capable of grinding components up to 240" between centers, and up to 12,000 lbs.
Once the shaft surface is prepared extensive masking is applied to control the coatings coverage. The finished coating on this proprietary forging meets tolerance of +.0000-.0005", with a 16 RMS finish. Ongoing production of these components is currently running at 30 shafts per week, with turn-around times of 2 to 3 days.
