Diameter Measurement Gages for On-Machine Accuracy and Repeatability

Diameter Measurement Gages

On-Machine Accuracy and Repeatability

Do you need to check the size of your turned parts while still on the lathe, grinder, or another machine center? ABTech’s precision diameter measurement gages are designed for measuring large diameter parts with better than .001” system accuracy.

DMG360 gages include a precision ground hardened steel wheel that rides on an uninterrupted OD surface of your part. Adjusters built into the wheel body allow you to easily align the wheel to the part.

Using your machine center to rotate the part the gage calculates the diameter from an average of four full rotations. A proximity sensor and trigger are used to precisely count off each revolution.

With optional handheld IR thermal sensors, you can enter the part and room temperatures and use the systems compensation factor.
