Composite Motors, Inc. (CMI) was originally founded as Joburn Tool in Attleboro, Massachusetts in 1966. The company focused on precision machining for the electronics industry. Over the years, the company increased its capabilities and transitioned to a manufacturer of customized brushless PMAC, PMDC and Hermetically Packaged Motor Controllers.

Today, our Precision Machining Services are still a cornerstone to our business due to our focus on Vertical Integration. CMI’s in-house Design and Manufacture of all tooling, jigs and fixtures for our motors and controllers provide significant benefit to customers for Cost Control, Quality and Time to Market demands.

What are Precision Machining Services?

Precision machining services are manufacturing processes utilizing equipment with Computer Numerical Control (CNC) Software to remove material from a workpiece. CMI utilizes the following CNC equipment:

  • Laser Cutting Equipment
  • Wire EDM
  • Vertical and Horizontal Mills
  • Waterjet Cutting Equipment

There are many advantages of precision machining services:

  • Precise: The ability to create very precise shapes and features
  • Versatile: Can be used to create complex shapes and sizes
  • Software Integrated: Computer-controlled tools allow for downloading mechanical CAD Files
  • Consistency: Can produce identical parts with each cycle

Composite Motors utilizes our Laser Cutting CNC equipment to support rapid prototype and low volume requirements. For production volumes, Wire EDM equipment is used to manufacture stamping tools for motor laminations and mechanical packaging of motor controllers.

Advantages of Manual Equipment

Since CNC equipment requiring programming for highly precise/detailed geometries, manual equipment can reduce lead times for less complex items such as:

  • Lathes
  • Mills
  • Hole Poppers
  • Grinding

Composite Motors offers high-quality and high-precision services for a variety of industries, including:

  • Military/Aerospace
  • Medical Devices
  • Industrial
  • Robotic
