Copper is a truly versatile metal.we often use copper materials to machine parts.there are many benefits to using copper for machined parts.Copper is one of the most versatile metals in the world, with high resistance to corrosion and great electrical and thermal conductivity.Far East Excellence usually uses CNC Milling and CNC Turning for Machining Copper parts. In this article, we will mainly discuss copper CNC Milling and CNC Turning machining methods.


CNC Milling
Copper alloys can be machined utilizing various techniques.CNC milling is an automated machining process that utilizes computerized controls to manage the movement and operation of multi-point rotary cutting tools.As the tools rotate and move across the surface of the workpiece, they slowly remove excess material to complete the desired shape and size.Milling can be used to create different design characteristics such as grooves, notches, pockets, holes, slots, contours, and flat surfaces.

Here are some guidelines for CNC milling copper or copper alloys:
Common cutting materials are carbide application groups such as N10 and N20, and the HSS grades
You can double tool life by reducing the cutting speed by 10%

When milling a copper cast alloy with a cast skin, reduce the cutting speed by 15 percent for a carbide group tool or 20 percent for an HSS grade tool.


CNC Turning
Another technique for machining copper is CNC turning, where the tool remains stationary, while the workpiece moves to produce the desired shape. CNC turning is an adaptable machining system used to make many electronic and mechanical components.

There are many benefits in using CNC turning, including cost-effectiveness, precision, and increased manufacturing speed. When turning a copper workpiece, it’s particularly important to carefully consider your speed — because copper is an excellent thermal conductor, it creates more heat than other materials, which increases tool wear over time


Here are some tips for CNC turning copper or copper alloys:

Set the cutting tool edge angle in the range of 70° to 95°

Softer coppers prone to smearing require a cutting tool edge angle of approximately 90˚


A constant cutting depth and reducing the cutting tool edge angle results in lower stress on the tool and increases both tool life and cutting speed
Increasing the angle between the major and minor cutting edges (the tool included angle) allows the tool to sustain higher mechanical loads and results in lower thermal stresses
There are also a wealth of other mechanical and chemical finishing processes, so it’s a good idea to evaluate all of your options when designing a copper machined part.
