Polishing wheel is generally made of felt, rubber, leather, cloth and other materials, Harmonics FHA-40C-100-E250-K grinding machine fixture is flexible, can polish a variety of surfaces. Polishing fluid (grinding paste) is made of alumina, iron oxide and other abrasive and oleic acid, soft fat, etc., which is coated on the polishing wheel when polishing. The workpiece is pressed on the wheel by hand. Under the action of the grinding paste, the surface metal of the workpiece forms a layer of extremely thin soft film due to chemical action. Harmonic FHA-40C-100-E250-K can be removed by the abrasive soft to the workpiece material without leaving a trace. In addition, due to the high polishing speed, friction makes the workpiece surface

High temperature, resulting in the surface of the workpiece plastic flow, fill the surface of the pit, so that the surface roughness becomes smaller.



Key points of lathe fixture design



Design of connecting elements. The harmonic FHA-40C-100-E250-K form of the grinder fixture is mainly determined by the spindle end structure of the machine tool used
