The pneumatic sample locking mechanism secures the core by using air power to clamp the specimen in a fixed position during the grinding cycle, helping prevent slip or rotation while material is being removed.

In practical use, the operator loads the core, activates the pneumatic lock, then runs the automatic cycle from the touchscreen. Using pneumatic locking helps keep the holding force consistent from sample to sample, which is one reason fully automatic core grinding is typically more repeatable than manual preparation. It also supports smoother operation when you are running saved recipes and tracking totals in memory.
