Go For A Smooth Finish With Finishing Compounds
Finishing is a term used to define the process of cleaning, polishing, deburring, coloring, separating and smoothing of parts or components, generally metals. Finishing compounds are compounds used in the process of finishing - they are defined as substances or materials that are used to give surface properties like softness, smoothness, flexibility, resistance to fire, resistance to corrosion, resistance to rusting and so on - to metal parts, wood, textile, leather etc. It is possible to impart a high quality to a finished product with finishing compounds so that the product comes out with the correct functionality, fit and aesthetics.
Mass finishing compounds are used to finish several parts together using machines like tumbling barrels or vibratory systems. The compounds are used to aid in deburring, descaling, polishing of ferrous and non ferrous materials etc. The typical mass finishing process involves putting the parts together with finishing media, water and finishing compounds into a barrel or vibratory machine and allowing them to vibrate or tumble together. As a result, the parts rub against each other or with the finishing media; the rough edges are smoothed out, debris and deposits are cleaned out and specific surface properties are imparted to the parts.
The finishing compounds can be used in closed loop and open loop finishing processes, which involves automatic or manual feeding of finishing media and compounds respectively. There are compounds that are made for wet use and those made for dry use. Compounds are also available for specific use with tumbling systems and those that work well with vibratory systems. There are some special properties given to the finishing compounds when they are manufactured. For example, deburring compounds are made to keep the deburring debris suspended during the finishing process to ensure that there is no re depositing. This way the surfaces are continuously kept ready to accept the abrasive action. Descaling compounds have properties needed to remove scales and assist the finishing media in descaling. Compounds used for polishing are made to provide conditioning to water, detergency, impart rinseability and brightening plus suspension properties to make sure that the debris is kept at bay.
Finishing media are used in the finishing process to clean, polish and deburr. Corn cob media comes under the head of dry finishing media. It is made from treating and powdering of corn cobs to provide abrasive action on parts being finished. As they are made from natural products, corn cob media is bio degradable and environment friendly. It is long lasting and reusable; it is also cost effective. It can be used in both vibratory and tumbling systems. The grit size of the corn cob media is determined by the finishing requirement – it varies depending on whether the finishing process needs to be gentle or rough, the nature of the surface being deburred etc. The corn cob media has very good absorbing properties and can absorb both water and oily substances with ease; proves very effective in degreasing and cleaning parts.
