CUTTING EFFICIENCY OF COATED ABRASIVE PRODUCTS
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.
