CUTTING EFFICIENCY
Although general in nature, this chart can serve as a useful guide as to what effect a change in a single
given factor in the specification will have on the cutting efficiency of coated abrasive products. Arrows
have been used to signify the trend direction. The length of arrows has no significance. Some important
machine and setup parameters have also been included since they do have significant impact on product
performance.
