Low Speed Dynamic Balancing of workpiece while on a vertical lathe
Low Speed Dynamic Balancing of workpiece while on a vertical lathe
(OP)
I need to dynamically balance a workpiece while it is still fixtured to a vertical lathe. The lathe table is approx. 1 meter in diameter. The speed is 100-200 rpm. Don't have a clear balancing tolerance yet.
The lathe has rigid bearings and with the relatively low speed I am uncertain as to the best selection of the sensor (acceleromter, velocity pickup...).
Does anyone have any useful insights to this problem?

RE: Low Speed Dynamic Balancing of workpiece while on a vertical lathe
I don't think that you have sufficient sensitivity for balancing vectors on such stiff machine for some better balancing quality. You may build some mechanical amplifier to get better sensitivity (resonator with low damping), but for better quality try balancing machines.
Hope this help.

Plus plus you have to evaluate the lathe's balance with the the workpiece removed.
