At Toolcraft, LLC, we specialize in close tolerance machining of specialty items, such as gages, tools, fixtures, prototypes, and machine parts. Our decades of experience have taught us to do this with maximum efficiency, which translates directly into cost savings for our customers. We fabricated the connecting arm shown here for a longstanding client in the gear manufacturing industry as a replacement part for one of their critical pieces of equipment.

Featuring 2.0" thick 4140 PH steel construction, this workpiece features overall dimensions of 6.0" in width and 20.0" in length. Our technically skilled machinists were able to hold tight +/-.001" dimensional tolerances when creating complicated geometries in this uniformly hard material. The keen eyes and precision measuring equipment in our inspection area validated we met the exact requirements of the specification.

In less than one month's time, the connector arm was replaced and our customer's equipment was running at peak efficiency. If you are interested in learning more about this project, or have a similar one and would like to discuss the details, contact us today.
