1. INSITU MACHINING OF TRUNNION JOURNALS
This is a process by which Raw Mill/Cement Mill Trunnion Journals can be repaired by INSITU machining at site. The scorings formed over a period of time, can be removed and the Trunnion Journal diameter will be undersized to standard diametrical tolerances as per OEM's specification. The Trunnion Journal will be stationary while our INSITU attachment will rotate around to effect grinding. This will generate true spherical surface. Using this state of art INSITU machine, any shafts upto 3200mm diameter can be INSITU machined/ground
