American Broach & Machine Company was founded in 1919 in Ann Arbor, Michigan. Today, American Broach continues the tradition of leading the broaching industry in innovation, engineering, and excellent workmanship. In addition to designing, building, and delivering over 6000 broaching machines, American Broach provides cutting tools for thousands of customers.

A problem they had is that the broach grinding  operation requires a high volume of water soluble coolant, which is constantly applied to the part and grinding wheel, and several linear optical scale failures created an unacceptable amount of downtime. The problem was solved with Newall’s linear encoders which carry an IP67 environmental rating and continually provide accurate, reliable readings, even when fully submersed in water, oil or coolant.
