Drilling Speeds and Feeds - UFL MAE

Drilling Speeds and Feeds . The speed of a drill is measured in terms of the rate at which the outside or periphery of the tool moves in relation to the work being drilled. The common unit and term for this velocity is surface feet per minute, abbreviated sfm. Every tool manufacturer has a recommended table of sfm values for their tools.

Nickel and Nickel Alloys- Machining - espimetals.com

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.

Ore processing – Waihi Gold

Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls. The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder. Rock is ground by the turning action of the mill, and impact from the hardened steel balls and the rock itself.
