Tornos SwissDECO - Achieve the impossible (500 mm deep hole drilling)

Beautiful

Hi! very cool and thanks for sharing. How do you ensure the drill does not walk? It seems we have a run out due to material not being straight and possibly runout or tool wear. How do you ensure your process accounts for those factors and produces straight deep holes? thanks!!

[@tornoschannel]

Thank you ! The external turning as well as the long drilling are done on the same spindle in order to minimize the runout. The maximum runout we had was of 0.20mm at the exit of the drilling. This application is made in brass for the purpose of the video, but the setup was made in titanium.

@@tornoschannel 500mm drill depth with only .2mm runout at the end of part is very impressive. What's the cycle time for just the hole in titanium? 40mins? Great setup, anything is possible if you think outside the box!

Hello @@steve0stang, thank you for your comment, the cycle time is just over 10 minutes for the hole 🚀

How did you rechuck on two different diameters? Awesome stuff! Is the real part titanium or stainless? Run time?

[@tornoschannel]

Hello Alex, we have a guidebush and a spindle on this machine, cycle time is 22 min; 17 min for the deep hole drilling we have to go slowly to not break the drill. To be honest we did not spent a lot of time to optimize the process we were focused on the practical feasibility here. Thank you for watching and for the nice comment

And the real part is made in titanium 👌
