Spurs & Helicals

Circle Gear, from day one, has been providing the industry with spurs and helicals. Using ultra reliable mid-twentieth century equipment, every bit of our 7500 sq. ft. “Job Shop” was utilized to make gears with outstanding quality. Fast forward today, to our 122,000 sq ft multi–building facility with the newest 21st century technology including robotic part loading. Only with dedication, technical know-how, and the ability to exceed customer demands could our little “Job shop” grow to be the industry leader it has become today.

Equipped for Success

Over the years we have built an impressive inventory of gear cutting tools that covers a wide range of gears types:

  • Diametral Pitch, Module, Circular Pitch
  • Standard Depth
  • Stub Depth
  • Involute Spline
  • Transverse
  • Pre-Shave
  • Pre-Grind
  • Sprocket/Silent Chain
  • Timing Belt

Our Sales and Engineering department will work with you to make sure your project is processed with the tool that best meets your application.

At Circle Gear & Machine Co., we are a full-fledged machining and manufacturing facility with the capability to produce custom spur and helical gears with an impressive range of sizes and diameters. Thanks to the versatility of our equipment, it’s not uncommon to see a cart full of 1” diameter parts placed next to a pallet with a 120” diameter gear.

Obviously, gear teeth are just one feature of a gear. We provide all the support to saw, turn, mill and drill, cut, shave, deburr, key, heat treat, hard turn, surface grind, diameter grind, and finally tooth grind. With over a hundred routing operations in our system, we are set up to handle any feature your project may have.

Proven Quality Gears

Quality is easily appraised with our Wenzel Geartec LH87 gearchecker. Charts, along with dimensional reports, can be provided so you can have no doubt your gears will perform as expected. Circle Gear’s (QMS) Quality Management System that is ISO-certified, ensures that from start of contract to shipment of product, every manufacturing step is monitored and traceable.
