What type of copper? Some types of copper have a machinability rating in the cellar. Copper expands at the tool and tends to pinch and hold and 

Cox professionals find that copper CNC machining is a smooth, easy process because copper is a good heat conductor that is easy to shape. Copper also has high 

Machinability of a material can be defined as the ease with which it can be machined. Machinability depends on the physical properties and the cutting conditions of the material. Metals and Alloys - Densities - Densities of some common metals, metallic elements and alloys - aluminum, bronze, copper, iron and more. Metals and Alloys

When it comes to machining, pure copper has poor machinability due to high plasticity and toughness. Alloying the copper with elements such 

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

the project was partially funded by the international copper association (ica), and this review was undertaken to assist this effort to understand and summarize the data and concepts of the metal

Figure 2: Micrograph of the chip at 573x after 20 holes (a), 400 holes (b), and 700 holes (c). All were etched in 4% Picral for 90 sec. The researchers concluded that machinability can be improved by the use of additives such as MnS as well as by changes in the microstructure similar to that of Mix D.

Machinability ratings are “relative” ratings. They compare the ease of machining an alloy to a standard. That standard is 160 Brinel hardness B1112 cold drawn steel machined at 180 surface feet per minute. B1112 was assigned a score of 1.00. The machinability of all other alloys is compared to the standard score of 1.00.
