  • GRINDING FOR TOOLMAKING

    suitable for grinding steel. The number and size of the carbides in a steel greatly influ-ence its grindability. The more carbides are present, and the larger they are, the more difficult grinding will be. For this reason, powder-metallurgical steels with smaller carbides are easier to grind than smelted steels of similar composition.
