An Introduction to Coarse Grinding of Woodworking Sheet Materials

A, The coarse grinding for a large area of sheet materials usually needs Y cloth and silicon carbide, which mainly involves 36#40#50#60#. The total amount is not big and not easy to dry up or sell up, so it doesn't need brand-sticking. It is generally recommended to use YC446 or a cheaper one called CXB508. But if abrasive belt with wideness1330 and length more than 2500 uses CXB508, its risk is quite bigger and it will be easy to wrinkle, whose reason is that the stiffness is not very good.

B, 36#40#60# of YC446 are mixed by aluminum oxide and silicon carbide, which not only refer to wind power but also are wear-resisting. Silicon carbide abrasives are mainly used for density board, shaving board, small wood splice plate and other plates with bigger rubber content, and also used in oily plate, cork board, etc.

C, Alumina abrasives can be used in ordinary wood. The oiliness of boards can not be big, or it will be blocked; The humidity can not be big, or it will not work; Cork board may be easy to slip. The sand-planting can not be too dense, or the sharp effect will be low, so operators should select the sand-planting density.

D, For abrasives, wood is easy to process, and there will not be a lot of wear and tear. The shape of abrasives and the shape of sand-planting are very important. The shape of abrasives need to be horned, and the sand-planting needs to be erect.

E, X5 and KX608 can be used for ordinary wood, whose have good stability on sand-planting form and cloth backing treatment. It is enough to be used in small broadband, and no longer than 2500 broadband. X cloth backing is not that great but economical and stable, whose sales have been growing. Small specifications wood surface sand, coated sand, X5 and KX608 are very awesome, and you can refer to typical specifications 170×7100.
