Stay Connected with Adams-ISC

Welcome to Adams-ISC

Adams-ISC in Rapid City was formed in 2011 as a merger between Adams Machining in Rapid City and ISC Companies in Minneapolis. Both companies share a strong history of delivering customer driven solutions in the industrial marketplace.

Adams Machining began in 1982 with the vision of providing the best possible service to companies needing custom parts and service through machining and welding; equipment and hydraulic repair; and pipe and vessel repair and rebuild. Incorporated in 1939, ISC Companies (Industrial Supply Co., Inc.) operates in three main business groups; bearings and power transmission distribution; machining and fabrication; and sensors, electrical controls, and panel design.


Together we form Adams-ISC, committed to being the region’s premier partner in delivering customer specific solutions to the industrial industry. Put our decades of collective experience to work for you. Whether you are retrofitting a machine or designing a new one, need replacement parts or fabrication of parts that don’t exist anymore, our staff is ready to collaborate with you from repair and maintenance to generating ideas for new designs and producing a finished product.

At Adams-ISC, we have the experience and the certifications to keep your equipment running safely. Seasoned technicians trained in electrical, mechanical, and hydraulic systems are available to respond to emergency breakdowns, planned maintenance, and machine upgrades at your facility. We can design, build, and implement complex solutions to real-world problems. In-house services are available for repair or rebuild of mechanical and hydraulic equipment.
