Rolling Mill & Chock Refurbishment
Over time, chock and housing surfaces can sustain damage from wear, corrosion and hammering. While flat bearings and lubrication are intended to protect against these things, improper flat bearing material choices, un-optimized lubrication or simply years of production can result in surface damage that requires machining to repair.
Left uncorrected, damaged mounting surfaces can lead to even more damage due to:
- bearings not being mounted flush, resulting in uneven impact and wear protection;
- corrosion caused by water seeping in behind the bearings;
- an increased or uneven gap, which hinders proper lubrication; and
- roll position, which dramatically reduces overall production quality.
D&R Machine Company has extensive experience in correcting multiple types of problems through precision reconditioning of surfaces. A team of trained experts uses custom designed milling machinery to accomplish reconditioning tasks quickly, accurately and efficiently. As well as addressing the screwdown to adjust movements that control ability and hold critical dimensions in the rolling process.
These efforts will return the highly precise mounting surfaces and production windows to a minimum of OEM standards while often exceeding them. D&R Machine Company’s experience runs the complete range of mill types from strip, bar, rail, structural and pipe with the ability to easily adapt to the requirements of each individual site and situation.
