  • Fantastic show - a life changer

    This show helped me make the decision to leave a corporation after 17 years and go and help and old friend with his machine tool dealership. The stories by the guests were inspiring.

I’ve been in the machine tool business for 30 years and found myself Googling manufacturing methods that I had no idea about. Very informative and well presented. Great wor... more

  • Losing its focus

    While I understand the use of the platform as a venue to help people hear stories and relate to others with differences, it’s not what I’m here to listen to. There is plenty of better content elsewhere for self help, marriage counseling or transgender stories. I’m disappointed in how it’s lost its focus on machining and business.

Best of Swarfcast: Talking Citizen CNC Swiss Lathes with Marc Klecka – EP 109

Swiss machines gain rigidity by using a guide bushing in addition to the collet, which reduces vibration and enables extremely accurate bar machining, while also allowing uninterrupted production of long parts and reducing the need for secondary operations.
