(ADCOLE Corp.: Marlborough, MA) -- A low-cost LED micrometer that validates if parts have been rolled to the proper depth and stress-relieved is available from ADCOLE Corp. The LED Micrometer Sensor for the Model 1200 Crankshaft Gage provides ±3 µm accuracy, ±1 µm repeatability, and 0.25 µm resolution. Capable of measuring fillet undercut depth (before and after rolling) at a 35° roll angle, journal straightness, and radial distance or journal shoulder to journal, this gage creates chart reports depicting any problem areas.

Providing three times higher accuracy and resolution than a laser micrometer, the ADCOLE LED Micrometer Sensor is attached to the follower carriage, and the Z-axis is located using the standard gage for start/stop measurement. Supplied as a standard feature on the Model 1200 Crankshaft Gage, the micrometer is also offered for retrofit. The Model 1200 features a menu-driven sequence builder utility for developing measurements sequences for new crankshafts and camshafts.

The ADCOLE LED Micrometer Sensor is priced at $49,000, and the Model 1200 Crankshaft Gage is priced from $275,000.
