Lapping is a machining process in which two surfaces are rubbed together with an abrasive between them, by hand movement or using a machine.
Double-disc grinding is an effective grinding method that employs abrasive wheels that grind and remove equal amounts of stock from both sides of a blank.
Deburring is a material modification method that takes sharp edges, or burrs from a material and leaves the material with smooth edges.
Ultrasonic cleaning is a conventional method for high-quality cleaning, utilizing ultrasonic energy to scrub the parts and a liquid solvent to rinse away the residue and loosened particulate matter.
