Machining Monel 400
Due to the high strength and work-hardening tendency of the 2.4360 material, machining 2.4360 monel 400 is more challenging than machining conventional materials. Here are some considerations:
- Tooling: Use carbide tools as Monel 400 work hardens rapidly. HSS tools may not be as effective.
- Cutting Speed: Use lower cutting speeds than when machining steel. Slow and steady processing is key to preventing excessive heat build-up.
- Coolant: Using the proper coolant or cutting fluid will help dissipate heat and extend tool life.
- Feed Rate: Use an appropriate feed rate to avoid excessive stress on the tool, which can cause work hardening and tool wear.
- Chip Control: Proper chip control is important to prevent chip buildup and tool damage.
