A joint Sandvik Coromant and Mazak seminar provided counterintuitive information on the metalworking market in general and machining heat-resistant superalloys in particular.
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.
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.
Read CTE's Fifth Biennial Salary Survey to learn which positions are earning more and how much more since the 2006 survey, which positions are earning less and how much less, and how benefit packages have changed.
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.
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.
