Tumbling Media And Compounds For That Great Finish
‘Media’ is the terminology used to define a material that is used to modify or alter the appearance of a part. It generally refers to an abrasive, but it could refer to any material that can abrade, clean, polish or separate parts. Tumbling media is used in general purpose metal polishing, deburring – both light and heavy, fast and extra fast and aggressive metal removal, fast, heavy cutting, jewellery polishing, burnishing etc. There are many types of tumbling media like ceramic performed shapes, plastic performed shapes, synthetic performed shapes, precision ceramic preformed shapes, carbon steel, stainless steel, hardwood, aluminium oxide, corn cob, silicon carbide grit and walnut shells are some of them.
A finishing media company has to give high quality products at reasonable prices to their clients. A fully equipped laboratory stocked with finishing machines where new processes are developed to meet even the toughest application will make them effective innovators. Plastic media is normally used for pre painted or pre plated finishes, polishing and in cutting fast and heavy duty. Plastic media are ideal for soft metals like brass and aluminium and stringy materials. It is useful for providing a smooth but dull finish. These media are long lasting and are built to cut fast and provide a fine finish. With a vast experience, a company can provide customized solutions to their clients. Ceramic tumbling media come in different shapes, sizes and composition. Ceramic media are used for fast deburring and tough metal removal. It is mainly used in cutting hard metals. When media of smaller dimensions are needed, ceramic media offers the best options. It is better than plastic media in supporting very heavy metal parts.
Dry finishing media of smaller dimensions are used to polish and finish smaller surfaces like jewellery. For this, cob and walnut shells that are treated are used and a finishing paste is also typically used for this. Very delicate surfaces of any size can also be finished using corn cob media. Corn cob is bio degradable and it is a tumbling grit. It can be applied as tumbling and vibratory media and can dry parts by absorbing oil and dirt, without scratching the parts’ surfaces. These products can be used to finish even very small and delicate surfaces effectively. Their product formulas can achieve 1 Ra finish and are made to handle even finishes of a delicate nature for decorative requirements.
There is a wide range of tumbling compounds to satisfy different client needs. Dry compounds, liquid compounds, burnishing compounds, cleaning compounds and deburring compounds are some of the available finishing tumbling compounds. There are compounds for standard deburring applications, burnishing of steel, part on part and applications in washing different parts. Walnut shells are treated and prepared by grinding them into different grit sizes. They are used in cleaning as well as polishing of surfaces. It is recommended as tumble media for polishing metals like aluminium, brass and bronze. They are soft abrasives but highly durable and angular. To learn more, go to http://gravcollc.com/
