They do be chunky tho.

Our newen epoc seat and guide machine uses single point cutters (imagine lathe tooling) which allows us flexibility unmatched by traditional form-cutter style machines. This gives us the ability to cut angles greater than 90 degrees so we can play with true “Venturi” style exhaust valves jobs.

Our newen has completed its first set of heads today. The finish this machine leaves is too good not to share!

Today we had a big win. Our seat and guide machine that has been steadily being worked on for the past year has cut its first chips under our ownership. The Newen epoc is one hell of a machine!
