In manufacturing technology, coating involves applying a firmly adhering layer to the surface of a tool or component. These application processes can be categorized as chemical, mechanical, thermal, or a combination of these methods. Among the various applications at Musashi, notable mentions include protecting the tool (e.g., indexable inserts, forming punches) and expanding process limits by enhancing the frictional properties of the contact partners. The latter is of particular importance in the cold forming of metallic materials. 

Shot blasting is a cleaning process used to eliminate scale after heat treatment in an open atmosphere. 

The objective of hard fine machining is to produce the micro (shape- and position-tolerances) and macro geometry (surface topography) of specific functional surfaces on a workpiece. Typically occurring towards to the end of the value chain, this machining process allows for achieving the highest accuracies and finest surfaces. Grinding is the most commonly used manufacturing process, employing multi-edged tools with geometrically indeterminate cutting edges to shape the workpieces. Cylindrical or surface grinding processes enable the finishing of diameters and flat surfaces. Gears are given their precision by continuous generating grinding, ensuring high concentricity and pitch accuracy as well as constant involutes and flank lines.
