5-Axis CNC Machined V8 Engine Block!

5-Axis V8 Engine Block. Less talk, more rock.

In this video, we let the Haas VM3 do the talking. If you’re familiar with the Business of Machining podcast, John Grimsmo and I discuss the importance of “spindle therapy.” This project is about being in the moment and thoroughly enjoying the process. The end result is icing on the cake. As we continue to learn and grow in our 5-Axis journey, so can you! Nothing is more awesome than being able to share this with you. So, kick back, relax, and enjoy!

After 5-Axis machining our V8 engine block, one of our interns, Alex, wanted to go the extra mile.

Today we’ll machine connecting rods using a custom fixture, the handle for the crank using mickey mouse corners, and finally some legs, which allow us to display the engine AND are the first and last crank shaft mounting brackets. Let’s dive in!

This project is a shining example of what it’s all about.

While I love running machines and making parts, being able to be a part of this community and pay it forward is unbelievably rewarding. Alex, our intern, took this project from start to finish. Workholding, S&F, fixturing–he did it all and he did us proud!
