What are the recommended machining parameters for copper parts?
Copper is a soft metal that can be machined without the use of any special equipment.
The recommended machining parameters for copper parts are:
- feed rate: 10 to 20 inches per minute (up to 2.5 mm per minute)
- spindle speed: 1,000 to 3,000 RPM (up to 5 mm/s)
- milling cutter diameter: 0.032″ to 0.063″ (0.81 mm to 1.60 mm)
- milling cutter speed: 0.084″/second (2.03 mm/s)
These parameters are derived from experience with other metals and are considered safe for most applications in the machining industry.

Copper cnc milling and machining components are used in industries like automotive, aerospace, medical
What are the surface finishes and post-processing options for copper parts?
Copper is available in a variety of finishes. It can be polished, brushed, or anodized. The polished copper is the most common finish and is suitable for general use. Brushed copper has a look that’s slightly less elegant but still professional.
There are a variety of post-processing options for your copper parts, depending on what aesthetic you’re going for and your budget.
- Post-processing options for copper parts include:
- Polishing: Polishing is one of the most common ways to give copper a clean, shiny appearance.
- Anodizing: Anodizing is another popular way to protect the surface of copper parts against corrosion and wear and tear.
CNC copper parts and precision components are hard to machine due to their high plasticity and toughness
Factors to consider in cnc copper machining
Copper is a great material for machines. It’s strong, pure, and easy to work with.
However, there are some things you should consider when deciding whether to machine copper or not.
- Cost: Copper prices can fluctuate greatly from year to year, so it’s important to research current rates before making the decision.
- Materials: Copper is hard to work with, so you’ll need to consider what type of metal you want your part made from.
- Programmability: While this may seem like an obvious factor, it’s important to understand how well your new machine can be programmed and controlled.

Benefits and drawbacks of cnc copper parts
- As copper and its alloys resist corrosion, they are a great option for use in a variety of industries where they are exposed to acids, seawater sprays, and other corrosion-causing elements.
- Copper enhances machinability because it is naturally ductile and malleable.
- Heat and electricity are well-conducted through copper. Since it is neither magnetic nor sparking, it is frequently used to create semiconductor components, electrical connectors, and other items. For making reliable connections, copper can be simply soldered or heated.
- It is possible to produce copper pieces with excellent reproducibility.
- Copper and copper alloy items have a high level of visual appeal.
