VT machining offers CNC Swiss Machining for Monel 400 (UNS N04400 / 2.4360), typically supplied annealed. Ni-Cu alloy with outstanding resistance to seawater and hydrofluoric acid.
CNC Swiss Machining Notes for Monel 400
Monel 400 can be Swiss-turned, but slower cutting data and guide-bushing clearances are set for this grade to protect slender features.
For estimating, a 100 × 100 × 10 mm block of Monel 400 weighs about 0.88 kg.

Request a QuoteFrequently Asked Questions
Does CNC Swiss Machining Monel 400 require dedicated tooling?
Most Monel 400 turning work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
What is the typical lead time and minimum order for CNC Swiss Machining Monel 400?
CNC Swiss Machining prototypes for Monel 400 can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
What tolerances can you hold for CNC Swiss Machining Monel 400?
Achievable tolerances for Monel 400 turning depend on the alloy, geometry and feature size. Turning holds diameter tolerances to around ±0.005 mm with concentricity within 0.01 mm. Exact figures are confirmed against your drawing callouts.
Why is Monel 400 a good choice for CNC Swiss Machining?
Monel 400 is strong and highly corrosion-resistant in marine/acid service, which makes it well suited to CNC Swiss Machining. We tune the process to the alloy so the finished Monel 400 turning part meets your dimensional and functional requirements.
