Speeds and feeds formachining tungsten

Copper Tungsten composites machine like gray cast iron.  These alloys can be bored, cut, drilled, ground, sawed, tapped, and turned. Copper Tungsten Alloys use speeds and feeds similar to Gray Cast Iron.  Copper Tungsten Alloy become easier to machine as the copper content increases.  The more tungsten content present the more care must be taken when machining.  Carbide tools are suggested for most cases and a coolant is optional.

Machining tungstenalloys

When sawing, use a bi-metal blade; blade pitch should be relative to the thickness of the material. Coarse blades can be run at low speeds, and finer blades run at higher speeds. Coolant can be used. Material can also be cut using high-speed abrasive cutoff wheels.

Tools – Carbide tooling is suggested. Increased clearance angles and automatic feeds are often used to avoid binding and seizing. Carbide drills will give a better tool life.
