SUCCESSFUL ON SITE MACHINING AT A COAL / BIOMASS POWER STATION: TURNING, FACING, DRILLING AND TAPPING.
Reekie were recently called in to machine the 240mm diameter x 195mm end of a reclaimer shaft that was heavily damaged by a slipping bearing. The job was located inside a biomass storage unit at a traditionally coal fired powered station in the North East of England. We used our JS29 turning machine, set true to an undamaged section, to remove damage marks and create a journal that was round and parallel within 0.05mm. An oversize sleeve, machined at our workshop in Renfrew, was then shrunk on. We then finish machined the new sealing diameter and bearing diameter. After facing the end of the shaft to clean up, we drilled and tapped four M30 32mm diameter x 50mm holes. The team were regularly interrupted due to ongoing transportation of biomass fuel in and around the area but coped admirably to complete the job successfully.
