The Secret Society of Lathe Trolls

My sense is that piezo based micro-positioning systems tend to be used in applications that work at DC and low frequencies or in higher speed applications at very small defections. Is this true? Mark Unless they do a type of inchworm type movement they are small deflection. What made me think of th...

Hi Darren, I've been thinking about experimenting with a PZT element head design. How hard would it be to get deflections of up to +/- .003" with a PZT element? I suspect you would have to couple the PZT to a lever of some sort to increase defection. Would this end up lowering the mechanical impeda...

Hello, A friend of mine asked me about using a motor controller I developed for a different purpose for use with a record lathe. I am constantly looking for more uses for it and thought it was a cool idea. So I sketched what I see a record lathe being: http://opencapitalist.org/content/record-cuttin...
