Parts

Nine parts, nine different reasons they were hard.

Photographed as they left inspection. Customer names are withheld under our supply agreements, but the material, the tolerance and the batch size are as machined.

The machine shop floor during the day shift

On the floor

Two shifts, then the lights go off and the pallets keep going.

The pallet pool runs unattended from 22:00, which is where the price on a repeat batch comes down. Setters load the next day's work before they leave, and the first-off is waiting on the inspection bench in the morning.
