Milling, Hobbing and other processes

We utilize hobbing, milling, generating, and 3D printing to produce commercial-grade gears for instruments, machine tools, and power transmission, as well as higher-quality gears for advanced applications. From spur and helical to sprocket, ratchet, worm and worm gear, rack, spline and bevel gears.

Inspection

Measurement over Pins (MOP) and Measurement over Wires (MOW) are common methods used to assess gear dimensions. Dual flank testing with devices such as the Vari-Roll provides additional insights into gear accuracy and performance, while span measurement and other similar techniques help evaluate various gear parameters. When these methods are combined with comprehensive dimensional checks using a Coordinate Measuring Machine (CMM), you can achieve a complete and detailed picture of both gear and blank quality. This integrated approach helps ensure that gears meet all required specifications and performance standards.

AGMA Quality Standards

Tolerances can be measured in our Microgear system and deliver reports. We use NIST calibrated measuring instruments and maintain our membership with AGMA, ensuring access to the latest industry standards and advancements in gear technology.

Quality Shop

We hold an ISO 9001 certificate, demonstrating our commitment to rigorous quality management.

Gear Expertise

At Evolvent Design, we practice the art of gearmaking. Our unique combination of advanced design skills and a fully equipped gear machine shop is rarely found together. If you're looking to accelerate your gear knowledge, this is the place to start. Gears present a steeper learning curve than most mechanisms—get there faster with our guidance.

Calculators

We've shared our in-house tools to help you design, inspect, and make your own gears. From our gear calculators to 3D gear generators these tools will make gear production easier and more understandable. Change Gear Calculator and other indexing machine setup tools and services.

Short Courses

Gears for Makers, a comprehensive one-day course to cover the history, math, and techniques. The course is located in our Ventura California shop where we will split our time between design, calculating and measuring, and half our time to machining hobbing or shaping gears.

We've supported a diverse range of clients: college SAE Baja teams, startups, mature companies, those fixing supply chain issues, and anyone curious about motion. We also offer reverse engineering for legacy parts to keep old equipment running.
