COPPER

Precision Copper CNC Machining

Copper, with its remarkable properties, has found its way into diverse industries. From medical devices to aerospace components, precision-machined copper parts are in high demand. Compared to other metals, copper offers its own challenges, so deep manufacturing expertise and experience is required to work with it. At RPM Inc., our seasoned experts and cutting-edge facility ensure top-quality copper CNC machining.

Copper CNC Machining: Challenges and Solutions

Custom Design: Our copper CNC machining service begins with custom-designed components. Solid copper bars, blanks, and cold-headed blanks serve as the raw materials. Unlike some metals, copper presents unique challenges during machining due to its hardness. However, most copper alloys offer excellent machinability, making them ideal for intricate parts. These alloys outshine pure copper in terms of workability.

Process Knowledge: Machining copper demands process knowledge. Our skilled team understands the nuances of working with this material. From tool selection to cutting strategies, we optimize every step.

5-Axis Equipment: Machining copper on 5-axis equipment requires expertise. Our experienced staff ensures precise results, even in complex geometries.

Copper CNC Machining Capabilities: Precision in Action

Wire EDM (Electrical Discharge Machining):

• We deliver wire diameters ranging from 0.006″ to 0.012″.
• Our 4-axis Wire EDM cutting for copper achieves high-quality results.
• The beauty of this technique lies in cutting metals without heat application.

CNC Milling & Turning:
Our well-equipped machine shop boasts advanced machinery:

• Vertical mills

Copper Alloys: A Spectrum of Possibilities
We work with various copper alloys, each with distinct properties:
Brasses:

• Widely used in diverse applications.
• Zinc addition enhances corrosion resistance, strength, ductility, hardness, and conductivity.

Bronzes:

• Made from copper and tin.
• Phosphorous deoxidizes these alloys, creating phosphor bronze.
• Gears and bearings benefit from their strength and hardness.

Nickel-Silvers:

• Similar to brasses but with added resistance to corrosion.
• Copper, nickel, and zinc combine harmoniously.

Copper-Nickel Alloys:

• Excellent ductility and corrosion resistance.
• Thrive in severe marine environments.
