WebOct 3, 2024 · General Rule: move the nozzle 20% or 1/5th of the spot size per revolution when blasting cylindrical parts. For example, if the spot size has a 1″ diameter, the nozzle should move position by 0.2″ after each pass. That means that the nozzle would move a total of 1″ in 5 passes. First, calculate spot size to get the step size.
