Publisher's Synopsis
Excerpt from Canadian Machinery and Manufacturing News, Vol. 18: July 12, 1917
Figure 1 shows the right way to grind a Stellite tool for machining Cast Iron. Give the tool a full Round Nose, and be sure the angle (a) is just sufficient to allow the tool to clear the work. This angle should never be more than six degrees. Whenever possible, operate the tool without top slope as shown in Figure 2, since the centre of the Stellite bar is not as hard as the outer surface. Figure 2 shows the improper way to grind the tool. Angle A is entirely too great, and will cause the tool to crumble. This tool should have a full round nose, and the top slope as shown will reduce the cutting qualities of the tool. Stellite tools cannot be burnt while grinding, because they have no temper. They always remain hard. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
