nickel milling grinding

Machining nickel alloys

The machining of nickel and nickel-base alloys can be readily accomplished providing fundamental principles affecting their machinability are understood and taken into consideration. Compared to other materials, the most significant characteristic of nickel alloys is that they are usually much stronger at metal cutting temperatures.

Nickel and Nickel Alloys- Machining - espimetals

Nickel alloys work harden rapidly, and the high pressures produced during machining cause a hardening effect that slows further machining and may also cause warping in small parts. Using cold-drawn stress-relieved material is preferable for machining. Hot-rolled is less desirable and annealed is least preferred for most applications.

Sizing Up Nickel Cutting Tool Engineering

Sep 01, 2000  Similarly, the high cutting zone temperatures that arise when machining nickel leads to premature tool wear. Though not as bad as aluminum, the formation of built-up edge when endmilling a nickel-based alloy is more noticeable than when cutting steel. The high machining forces created when milling nickel causes workhardening of the part.

For the mining industry, our semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.
