How to work this show
Bring the part: material, tolerance, volume. Ask for the cycle time on your geometry, the control version and who services the machine in your area.
Before the show, shortlist exhibitors from the official exhibitor list. After it, compare the machines you saw in the MBB machine directory and work out the installed cost with total installed cost.
Write down the material, tolerance and volume you need before you go. Ask every exhibitor the same questions, then compare the answers on MBB.
