Precision Machining

Gearing. Rotor Hubs. Housings.

Expertise in the Plant Means Reliability in the Air.

Whether using customer-supplied blueprints or our own CAD/CAM models developed from data sets and specs provided by end-users, Timken’s Aerospace Drive Systems’ (ADS) engineers use a rigorous process to ensure repeatability during manufacture. By generating a detailed 3-D model of the required part, tool or fixture, and the latest in machine programming technology, ADS is able to maximize quality, efficiency and on-time delivery.

As proud as we are of our investments in the latest CNC/DNC machining centers, and 5-axis high-speed milling equipment, it is the combined centuries of experience of our engineers and machinists that has put us – and will keep us – at the forefront of the industry.
