Surface machining unit
Abstract
Abstract PURPOSE:To protect a work from damage or deformation due to adhesion of foreign matters such as polishing agent, glass chip, rust onto the adsorbing face by providing a cleaner for previously cleaning the adsorbing face of pressure plate and the surface of roughly machined face of work. CONSTITUTION:Three roughly machined works 4 are cleaned through cleaners 22, 22. At the same time, the vacuum adsorbing boards 20, 20 of pressure plates 3A, 3B are cleaned through cleaners 21, 21. Thereafter, three works 4 are suction held to vacuum adsorbing boards 20, 20. Then the plates 3A, 3B are lowered to press the polishing face of work 4 against the surface of diamond pellet 2 with predetermined pressure. Thereafter, the surface plate 1 is rotated to polish the work 4 for predetermined time. Since the vacuum adsorbing boards 20, 20 and the work are cleaned through the cleaners 21, 22 to remove the foreign matters such as polishing agent, glass chip, etc., the machining face of work 4 is protected from flaw or deformation.
