The Arnold in-process grinding gage helps operators control finished size while cylindrical grinding is underway, reducing interruptions and removing guesswork from the final approach.
Arnold OD in-process grinding gage
Measure during the grinding cycle
After the gage is set with a known master or size, the operator grinds until the indicator returns to zero. The spring-mounted gage maintains sensitive support during grinding and retracts for part loading.
- In-process indication without stopping to check size
- Tungsten-carbide contact points for wear resistance
- Accuracy and repeatability up to 0.0001 inch for suitable applications
- Fitment options for major crankshaft and outside-diameter grinders
- Parts, instructions, and repair support available
