Selecting The Proper Abrasives. Part Two

By Jeremy Stone

By using abrasives without risk one of the most fundamental rules for the use of the products of grinding is without risk with the match gritting with the machine being employed. The catalogues of the manufacturers of abrasives indicate clearly which products are designed for which factory. Some employ icons or other charts of machine premise of abrasive matches. The operators should also seek similar information on the packing of product. In fact, the rule of safety from the not 1 for all the abrasive discs and the wheels are lira and to follow the information of safety included on the packing of product. If the packing were thrown, you ensure to know what you assembled on a machine and to follow suitable procedures of safety. What follows are ends for correctly employing and maintaining gritting.

General: * Not to rectify close to flammable materials. * If possible, parceling out or sand in a well-ventilated sector. * Protection of eye and face of use. * Gloves of safety of use. * To hold the grinding machine with the two hands. * To direct the sparks far from your body and far from the spectators. * Not to carry the clothing of coward-fitting of precision. * To wear the shirts or the guards of arm length-sheathed and the long trousers. * Not to carry the clothing polyester-type while rectifying. The polyester is an oil by-product and is flammable.

* If necessary, to employ a mask of dust or an approved respiratory protection adapted for materials being ground or being rectified. * To carry the protection of hearing when noise exposure exceeds the established levels of threshold. * If chattering or the vibration occurs during grinding, to stop the tool immediately. To determine the cause of the problem and to correct it before continuing. * To turn the actions; to employ on a first-in, the first-outside bases.

* Not to rectify soft metals on large wheels of grinding of granulation-size. Soft metal can accumulate in the wheel, probably making it break or causing soft metal with the "fly" in addition to wheel. To use the silicon carbide wheels for applications of non-steel such as carbides of grinding, the cast iron, and all non-ferrous metals. To employ aluminum oxide for the applications out of steel such as the steel of carbon, the parts forged of iron, the stainless steel, and other alloys.
