Metal buffing machines are sometimes referred to as metal polishing machine. Polishing and buffing processes are highly customized and these two types of highly customized machines are utilized to polish soft metal materials such as copper and brass items. During the polishing operation, the two mops spin at high speed when the ON switch is pressed by the users, and polish should be applied to the rotating mop before pressing the work against it.
When the machine is doing buffing process, the procedure involves the shining process of the targeted metal. In other industrial sectors other than metal working it may be composite materials using a cloth wheel impregnated with cutting compounds or rouges. The cloth buff will hold or carry the compound, while the compound does the cutting process as planned. There is a misconception that a polished surface has a mirror bright finish, yet most mirror bright finishes are buffed instead. So, the two are slightly different.
Metal buffing adopts a loose abrasive measure that is applied to the work wheel. And polishing is a more aggressive process compared to buffing. Buffing is less harsh in process, and leads to a smoother and brighter finish quality. In the metal working process, sometimes people also treat buffing as a way to enhance the appearance of an object and help to prevent the contamination and pollution of the buffed objects such as some instruments. Buffing and polishing can remove oxidation and create a reflective surface, and some exquisite procedure can even prevent corrosion in pipes.
For buffing and polishing to be done unto the work pieces, the condition at hand is the first reference. This determines what types of abrasive will be applied unto to materials. If the material is unfinished, then workers would starts with a rough abrasive value, ranging from sixty to eighty. Each following stage utilizes a finer abrasive values adjusted by operators, such as a hundred and twenty, two hundred twenty, four hundred, etc. The grit value will go higher and higher until the intended finish value is accomplished.
From rough grit to finer grit, first the rough grit will remove obvious imperfection traces within the metal surface such as pits, lines, or nicks. The finer abrasive tools leave very progressive finer lines which are not visible to human eyes. When the process goes to the eighth of the finish level, it requires polishing and buffing compounds and polishing wheels will be attached to a high speed polishing machines or electric drilling machines. Some polishing machines may be designed specifically to use in dry conditions, most polishing processes need lubricants like kerosene or other lubricants and cooling medium. Furthermore, buffing may be achieved by hands with a stationary polisher or die grinder, or it may be automated by some other specialized equipment that can process the whole procedure automatically once it is settled down.
When it comes to buffing, the following steps are comparatively simple. The buffing processes can be achieved by two ways. One is the cutting motion and the other one is named coloring motion. Cutting motion gives a uniform and semi bright surface finish. This work is conducted by moving the work pieces against the buffing wheels that are rotating. The pressure value may be raised by operators from medium level to hard level in this method. If the operators choose the coloring motion based on their working requirements, the method moves the work piece objects with the rotating of the buffing wheels and this method grants a bright and shiny finished surface. Contrary to the cutting motion, the coloring motion only allows for medium to light pressure values to proceed.
The wheels for buffing are also called mops. They are made from either cotton or wool cloth materials. These raw materials are taken to make buffing mops bleached or unbleached. There are many options of the buffing mops, such as loose cotton, canton flannel, treated spiral sewn, treated vented, string buff, sisal rope, sisal, etc. These items are subjects for users to choose based on their buffing requirements, and the related material and roughness levels shall be taken into consideration. For instance, many pipes are taken to be buffed in order to prevent corrosion and to eliminate the locations in which bacteria or mold reside in.
