Selection principle of cloth wheel of abrasive belt polishing machine

1, the material of the thrown workpieceGenerally, the material of the thrown workpiece is divided into two categories, one is metal, one is non-metal, metal can be divided into two categories, one is iron metal, including: iron, stainless steel, alloy steel, carbon steel and so on. One is non-ferrous metals, including: copper, brass, bronze, zinc, aluminum, nickel and so on. And non-metal, including: plastic, paint, wood, stone and so on. Often thrown workpiece material is different, then the choice of cloth wheel types are different, the basic choice of methods, are considered to be thrown workpiece surface hardness, like iron metal, its surface hardness is higher, so the choice of hemp wheel, to achieve its cutting effect, if not iron metal, also choose hemp wheel, then polished, the surface residual marks are thicker, Most of them are not accepted by customers, so non-iron metals, most of us use cotton wheels to polish.2. According to the sanding number of the previous projectOften the number of sanding before the project, Directly affect the polishing operation of the cloth wheel, polishing slurry or polishing has the choice, if the choice is improper, it will cause unnecessary cost waste, which adjustment and collocation, is also very important, the user for the use of polishing materials characteristics and composition, must understand very clearly, otherwise the best polishing materials, used in inappropriate places, can not achieve the desired effect.3, according to the type of polishing equipmentAutomatic polishing machine and manual polishing machine, the basic selection of cloth wheel method is completely different, the main reason is that the thrown workpiece of the automatic polishing machine is fixed on the fixture, and the cloth wheel shaft group is moved into and contact with the thrown workpiece to achieve polishing action, or the thrown work is fixed on the fixture, through a conveyor belt into the side or below the cloth wheel shaft group contact with it to achieve polishing action, And the manual polishing machine, is fixed by the cloth wheel shaft group, by the operator hand thrown workpiece and cloth wheel contact, to achieve polishing action, in other words, different kinds of polishing machine, the selection of the basic form of cloth wheel, can be said to be almost completely different.4, according to the shape of the thrown workpieceOften use the type of polishing machine and the shape of the thrown workpiece to confirm, the form of the cloth wheel selection can be roughly determined, the general throwing plane workpiece, most of the choice of a harder solid cloth wheel, and then according to the machine speed size, and the contact pressure, and then make some adjustments, but the drop is large, the shape of the complex profile of the thrown workpiece, in the automatic polishing machine, choose to use a softer elastic The cloth wheel, in the manual polishing machine, the choice of polishing contact mask elasticity, the base position of the cloth wheel is very hard.We need to choose the right Brune according to the material of polishing, so as to achieve the highest efficiency of polishing and achieve the effect of twice the result with half the effort.
