cost grinding description

Definition of Grinding. Grinding, an abrasive machining process that uses a grinding wheel as the cutting tool, is capable of making precision cuts and producing very fine finishes. The grinding head can be controlled to travel across a fixed workpice or workpiece can be moved while the grind head remains in a fixed position.

Fine grinding produces a surface with little deformation that can easily be removed during polishing. Because of the drawbacks with grinding papers, alternative fine grinding composite surfaces are available, in order to improve and facilitate fine grinding, A high material removal rate is obtained by using grain sizes of 15, 9.0 and 6.0 µm.

The molds can be fabricated, CNC machined, cast, or formed from epoxy or aluminum at a lower cost and much faster than tooling for other molding processes, especially for large parts. Rotomolding creates parts with nearly uniform wall thickness. Once the tooling and process are set up, the cost per part is very low relative to the size of the part.

Understanding Metal Stamping. Metal stamping is a cold-forming process that makes use of dies and stamping presses to transform sheet metal into different shapes. Pieces of flat sheet metal, typically referred to as blanks, is fed into a sheet metal stamping press that uses a tool and die surface to form the metal into a new shape.
