Industrial Applications

1. CNC Precision Machining Quality Control

Measuring the depth of milled pockets, blind holes, and stepped features of metallic components on the machining shop floor directly after manufacturing.

Problem Solved

Standard gauges can suffer electronic failures due to the presence of splashing cutting oil and fine metal shavings. The IP67 rating and coolant-proof housing of the 571-252-20 allow operators to execute reliable, precise measurements without clean-up delays.

2. Automotive Component Quality Assurance

Verifying the depth of critical grooves, slots, and seals in automotive engine blocks or cylinder heads.

Problem Solved

Manual data logging on high-volume production lines is slow and highly prone to human transcription errors. Incorporating the SPC digital data output allows direct connection to data collection systems, automating data entry for 100% traceabilty.

3. Aerospace Fastener Counterbore Inspection

Inspecting the depth of precision counterbore holes on composite and aluminum aerospace wing panels to guarantee fasteners sit completely flush.

Problem Solved

Minor dimensional deviations in counterbore depths compromise structural and aerodynamic efficiency. The ±0.02 mm high accuracy, micro-lapped 100mm base, and 0.01 mm resolution ensure strict alignment with rigid aerospace manufacturing tolerances.
