WHAT WE BUILD

Precision Capabilities

Every service backed by ISO-certified processes and delivered to exact specification.

Gear Manufacturing

Custom spur, helical, bevel, and specialty gears are manufactured to tight tolerances for reliable power transmission in demanding applications.

  • Spur and helical gears
  • Specialty and custom gear profiles
  • Prototype to production volume
  • Tolerances to drawing specification

Shaping

Our Fellows gear shapers cut internal gears, external gears near a shoulder, and internal splines that hobbing can’t reach, with a shaping stroke up to 6 inches, a capacity many shops in our region don’t have. Whether the part calls for a stepped shoulder or a tight internal profile, shaping gets us there.

  • Internal and external gear shaping
  • Internal splines
  • Shaping stroke up to 4.5″
  • Prototype to production volume
  • Tolerances to drawing specification

Splines

Internal and external spline cutting for demanding power transmission components requiring accuracy and durability.

  • Internal spline cutting
  • External spline cutting
  • High-accuracy, high-durability

Broaching

High-precision broaching services for consistent internal profiles and complex shapes at production volumes.

  • Internal profile broaching
  • Keyway broaching
  • High-volume production
  • Consistent, repeatable results

CNC Turning

Advanced CNC turning for shafts, hubs, and custom cylindrical components with exceptional repeatability.

  • Shafts and hubs
  • Custom cylindrical parts
  • Tight tolerance repeatability
  • Wide material capability

Milling

Multi-axis milling for detailed geometries, tight tolerances, and complex part configurations.

  • Multi-axis milling
  • Complex 3D geometries
  • Tight tolerance profiles
  • Custom configurations

Drilling

Accurate drilling and hole-making services for both production runs and custom projects.

  • Production and custom drilling
  • Tight positional tolerances
  • Burr-free finish
  • All material types
