DIAMOND TOOLS - INSTALLATION
	Set the Diamond Tool at the Correct Cutting Angle   When the single point diamond tool is set too high, the wheel may grind away the metal holding the stone. The diamond may be lost and dressing results are poor. When the single point diamond tool is set too low, or on center, the grinding wheel will quickly grind away the point of the diamond. A flat point on a diamond cannot effectively dress a wheel.   A single point diamond should be set at an angle between (10° and 15°) degrees below the centerline of the grinding wheel. Frequent turning of the tool will ensure a sharp point. It's like using a pencil. Press straight down on it and you'll soon wear the point flat. Use it an an angle and it writes better because it's self sharpening. There are some exceptions to these rules: Certain special tools, blade type tools , radius forming tools are designed to be used at other angles.   See that the Tool is Set Tightly in the Tool Holder You can't dress a wheel properly unless the diamond tool is set and secured rigidly in the tool holder. Diamonds require proper support and a minimum amount of overhang. Loose tools can cause vibration. This vibration creates chatter diamond marks, gouging in the grinding wheel. This also results in premature failure of the diamond tool.   Other Sources of Vibration Problems If the tool is properly mounted and vibration or chatter still persist, check the following: Is the wheel properly balanced? Is the wheel loose on the spindle? Are spindle bearings loose? Is the spindle out of round? Is the vibration source another remotely located motor or pump? Has the diamond been correctly selected? Use larger blocky diamonds for coarser grains, and smaller sharper diamonds for fine grain wheels.
