Engineering Tip: When to Choose CNC Machining
CNC machining is the preferred choice when you need tight tolerances (±0.025 mm or better), no tooling investment, fast delivery, or a wide choice of certified materials. For production volumes above 1,000 pieces of simpler geometries, casting or forging may offer cost advantages — our engineers can advise on the optimal process for your application at no charge.
