Installing an asset is a critical step that can impact reliability short term and long term. By investing in the installation, the asset will experience less premature failures and extend any wear out mechanisms that are present in the asset. The machine base must be free of corrosion, damage, and possess the required flatness runout which depend on the size of the equipment . The machine base level, coplanarity and flatness can be achieved using surface milling or shimming. There are mainly 2 type of surface milling for in-situ machining: circular and linear which are catered for round and squarish surfaces respectively.
