With increased angle, quicker rounding occurs, but it also weakens the blade rigidity. The most common top angle used in centerless grinding is 30 degrees. As the diagram below indicates, lower angles are used when grinding heavy workpieces, which help minimize vibration. Workrest top angles typically range from 45 degrees down to 20 …Web

Grinding is used to finish workpieces so that they meet the required surface finish quality. It rids unwanted material from the workpiece, like any rough texture that remains from previous machining applications. Grinding machines or tools use an abrasive wheel to remove metal from the workpiece. When the wheel rotates, it cuts material off …Web

governed motor is shown in Fig. 5. If a power tool is to be used optimally, the operator obviously needs to know which rotational speed gives maximum power. A non-governed tool generates maximum power at 50% of maximum rotational speed (rpm). On a governed tool, this optimal point can vary between 75–90% of max rpm (also shown in Fig. 5).Web

However, be sure the wheel is rated to run at the new speed. The maximum operating speed (MOS) will be stated on the side of the wheel. Reduce feed rate. Reduce depth of cut. Increase the number of spark-out passes. This component is ground to a surface finish of 3.0 microinch Ra.Web
Slower = Softer. At slower wheel speeds, there is a higher force per abrasive particle causing the grain and/or bond to break down quicker. Faster = Harder. At higher wheel speeds, there is lower force per abrasive particle making both the grain and bond seem more durable and resistant to breaking down as designed.Web
