💡 What determines whether a sturdy cnc extension bar survives repetitive high speed cutting cycles?
Mating tolerance drives reliability more than raw metal thickness ever will.
- Match outer diameter profiles to your existing chuck housing exactly.
- Load test the setup with light runs before pushing full feed rates.
- Store spare bars clean to prevent rust from wrecking perfect seals.
