BROACHING
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.
