Large Hydraulic Valve Bodies

The ability to machine complex geometry parts and meet the demands of just-in-time delivery schedules are two qualities that set Smoky Mountain Machining, Inc. apart from our competitors.  This family of hydraulic valve body parts was comprised of 15 different aluminum bodies and 2 different ductile iron bodies, all ranging in size from 7 x 6 x 3 inches to 14 x 11 x 6 inches. The eccentric geometry of these large valve bodies utilized as many as 55 unique tools to machine, and the complex manufacturing process also required a custom bushing and staking press operation during the sub assembly process between machining operations to produce the final parts.

Streamlined operations and careful planning enabled us to meet demand requirements that ranged from 10 parts per month for some part numbers up to 150 parts per month of others. To learn more about this project or how our ability to machine complex parts on demanding schedules can help you with your application, contact us today.
