Vibration forms. Common forms of vibration on grinding machines tend to fall into two categories – force vibration and self-excited vibration. Force vibration includes wheel imbalances, damaged bearings, bad motors, or grinding wheel imbalances. Force vibration can be present even when the grinding wheel is not in contact with the workpiece.
The machine industry has undergone several developments in the past years, and reducing the cost and time required for machine designing is important. In this study, the vibration characteristics of a precision grinding machine were obtained through experimental modal analysis and finite element analysis. The experimental modal analysis employed single point excitation, and the equipment used ...
vibratory polishing machine for Metal Working has a ring chamber to hold abrasives (stones) and work pieces. When the machine is working, it makes three-D high frequency vibration. The grinding stones and the work pieces are rolling spirally forward and they are grinding each other during the rolling.
the machine while controlling the head of the grinder. A vibration reducing flange (VRF) used to clamp grinding or polishing disks produced mixed results. In some cases it was found to reduce vibration levels by between 1% and 12% on either the support or the throttle handles; but it also caused increases of between 3% and 94% in others.
Isolating the grinding machine from floor and other sources of outside vibration. Increasing structural stiffness to reduce amplitude of harmful vibration. Utilizing "active force control" mechanisms to counteract unwanted vibrations that cannot be eliminated through passive means.
