04 / Quality

Measured
Before It Leaves.

Parts are inspected right where they sit, with machined features measured in 3D.

Portable CMM

FARO Arm

Takes the measurement to the part, so weldments and assemblies are checked without moving them.

  • Large parts measured in place, on the machine or the floor
  • Alignment checks during complete builds
  • First-article inspection

CMM System

Keyence CMM

Fast, repeatable 3D measurement of holes, bores, positions and profiles against the print.

  • In-process checks between operations
  • Final inspection before parts ship
