a. In many cases tougher grade carbide and sharper geometries will help to reduce vibration, but these are prone to chipping. Proper cutting angle and chip breaking can at least partially account for this; b. Use anti-vibration or "Silent Tools" offered by Coromant for example, for long reach applications. c.
Find the vibration frequency using this relationship, and if it matches the rotation speed of the grinding spindle, then this indicates that the grinding wheel, wheel flanges or the grinding spindle itself is a likely culprit. Change the wheel, tighten the flange bolts, or perhaps just change speed, and that much might be enough to cure or ...

Many tools are now available that are designed to produce less vibration. Reduced vibration tools should always be used with full-fingered anti-vibration gloves that are certified to meet international vibration standards (ISO 10819). Some hand-held power tools can produce a lot of vibration. Certain tools generate vibration levels so high …
Woodworking tools may cause vibration that could lead to "white fingers" or hand-arm vibration syndrome (HAVS). This is especially dangerous when proper damping techniques are not applied, if machines are not maintained, if tools are not alternated, or if a worker uses a vibrating tool for consecutive hours during a workday. Workers need to be ...
Comparing the vertical tool force histories, T2 and T4 produce different force variation patterns, showing that T2 with high vibration amplitudes creates greater vibration effect and greater force reduction earlier in the process than that by T4, as it takes longer for T4 to create vibration effect, depending on groove dimensions.
