While using a single cutting fluid to machine and grind all workpiece materials may not be economically feasible, many machine shops can reduce their number of metalworking fluids.
Honing an engine's cylinder bores enhances their geometry, surface finish and dimensional accuracy, improving their fit and alignment with pistons and thereby increasing the engine's life and power density while decreasing its vibration, friction and emissions.
Grinding round HSS cutting tools can be more efficient than milling them. Being able to dress new hybrid metal/polyimide-bond wheels on the grinder adds to the efficiency.
Holding large workpieces, especially heavy ones, requires parts manufacturers be more mindful of workholder and machine tool limits than they have to be with smaller workpieces. Also, shops may need to improvise when a conventional workholder can't secure a large workpiece.
