Machines for in-site crankshaft grinding & in-site milling
-In-site grinding of crankpins from D150mm to D600mm.
If the crankpins are greatly worn they will be milled with a tool or cutter and then ground. The rods may require rebuilding after grinding.
-Rebuilding of engine support bearing sleeves. Inspection of sleeves for cracks.
Micrometric inspection of journals. Laser check of bearing sleeve concentricity.
treatment of support bearing faces. Installation an tightening of cylinder block. Installation of rod. Alignment of rod. Treatment of support bearing sleeves and restoration to their original dimensions.
-In-site milling of block face – sleeve – cover.
