1, the material of the thrown workpiece Generally we divided the material of the thrown workpiece 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, etc. And non-metal, including: plastic, paint, wood, stone and so on. Often thrown workpiece material is different, the selection 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 more choose the wheel, in order to achieve its cutting effect, if not iron metal, also choose the wheel, then polished, the surface residual cast marks are thicker, most not accepted by customers, Therefore, non-ferrous metals, most of us use cotton wheels to polish.

2, according to the sanding number of the former project often the sanding number of the former project, directly affect the selection of the polishing operation of the cloth wheel, polishing paste or polishing paste, if the choice is improper, it will cause unnecessary cost waste, which adjustment and collocation, is also very important, the user for the characteristics and ingredients of the materials used, must understand very clearly, otherwise the best polishing material, If used in inappropriate places, the desired effect will not be achieved.

3, according to the type of polishing equipment automatic 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 the 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 the polishing action, in other words, different kinds of polishing machine, the basic form of the selection of cloth wheel, can be said to be almost completely different.

4. According to the shape of the thrown workpiece, the type of polishing machine is often used and the shape of the thrown workpiece is confirmed, the form of the cloth wheel selection can be roughly determined, the general throwing plane workpiece, most of the hard cloth wheel is selected, and then the contact pressure is added according to the size of the machine speed, and some adjustments are made, but the drop is large, the shape profile is complex and the thrown workpiece is thrown. In the automatic polishing machine, choose a soft and elastic cloth wheel, in the manual polishing machine, choose a cloth wheel that touches the elasticity of the mask and the base position is very hard.

We need to choose the right Brune according to the material of polishing, so as to achieve the high efficiency of polishing and achieve the effect of twice the result with half the effort.
