James Tool has been developing and building fixtures for over 34 years. Our engineers and workholding specialists research and develop the most efficient workholding solutions for our customers.

We develop designs using the latest 3D Solidworks®. Once developed and models are created we utilize MasterCam® to assist us in the manufacturing process. Our build and test area is dedicated and well equipped to build the most complex hydraulic fixtures.

We research, develop, and build over 300 fixtures each year. Many of our fixtures utilize multiple pressures, sequence clamping, clamp confirmation and air part confirmation for robot loading. Our fixtures are developed and built for many industries including: Automotive, Medical, Transportation, Aerospace, Heavy Truck, and Household Appliances. – Click for industries served

A James Tool fixture is extensively tested in one of our PLC controlled custom-built hydraulic test stands. These test stands can replicate a CNC machine’s hydraulic system. This final step in the fixture build process was developed so that the part being clamped is under the same production conditions.
