BROACHING

Broaching Services

CUT COMPLEX SHAPES FAST, WITHOUT TYING UP CNC TIME

Broaching is one of the most efficient ways to cut keyways, splines, and other precision shapes into metal parts. By using a hardened multi-tooth tool called a broach, we can quickly remove material and form internal or external features that would otherwise slow down production on a CNC machine.

This process gives you consistent results at high volumes without extending your CNC setup time or cycle time.

Our metal painting capabilities are ideal for:

  • High-quantity parts that require keyways or slots
  • Internal or external profiles with repeatable tolerances
  • Projects where CNC hours are limited or costly

Broaching can be a strategic way to keep your costs down and your output high, especially on long-run defense or industrial projects.

FAST, REPEATABLE RESULTS

Broaching takes what would be a time-consuming CNC task and streamlines it into a fast, repeatable solution. Because it happens outside the CNC process, it keeps your production lines moving and your tooling costs lower. Whether you need straight, circular, or custom forms, broaching helps simplify the path from raw stock to finished part.

WHY LEWIS FOR BROACHING?

  • In-house broaching for speed and quality control
  • Ideal for complex shapes like keyways and splines
  • Trusted by defense and industrial manufacturers
  • Integrated with machining, inspection, and assembly

We keep the process lean and efficient, so you get finished parts faster, without sacrificing precision.
