Development of verticalspindle rotary surface grinding

components of the machine is estimated to be 10 times higher than the rotary table or spindle. As a result, the measured loop stiffness of the developed machine was 4. Conclusions The next generation verticalspindle rotary surface grinding machine for large scale siliconwafers was developed and its static stiffness investigated.

What's "Hydroviscous" Spindle Damping? : Modern Machine Shop

Nov 02, 2015 · What's "Hydroviscous" Spindle Damping? improving a spindle's dynamic stiffness to boost cutting and grinding performance for a range of appliions. Natural vibrations within the spindle of a machine tool or grinding machine can limit cutting depths, reduce material removal rates and diminish surface finish quality.
