We use advanced CNC machines and a variety of quality inspection equipment to ensure the delivery of qualified products. We ensure close tolerances and excellent surface finish. We offer free samples and OEM customization.
Machining Process
The process of CNC machining copper
The CNC machining process for copper involves a sequence of automated operations.
CAD Model Preparation
A 3D model is designed using software like SolidWorks or AutoCAD, specifying critical dimensions and tolerances.
CAM Programming
Toolpaths are generated in CAM software, selecting appropriate cutting tools, spindle speeds, and feed rates.
Workpiece Setup
Copper material is securely clamped onto the CNC machine bed, ensuring alignment within 0.02 mm.
Machining Operations
Processes include milling, turning, and drilling, conducted under controlled cooling to prevent overheating.
In-Process Inspection
Dimensional checks are performed using coordinate measuring machines (CMM) to verify compliance with design specifications.
Post-Processing
Deburring, surface polishing, or plating (e.g., nickel or silver coating) is applied as required.
Processing characteristics of copper and copper alloys
1
Copper alloys (such as brass H62 and bronze QSn6.5-0.1) have slightly higher hardness than pure copper (H62 Brinell hardness is approximately 60-80 HB), lower ductility, and relatively better processing performance. They are commonly used materials for CNC machining.
2
The thermal conductivity of copper is much higher than that of steel and aluminum. During processing, the cutting heat will be quickly transferred to the workpiece, tool and fixture, which may cause dimensional deviation of the workpiece due to thermal deformation (especially thin-walled and slender parts), and the tool edge temperature will be too high, accelerating wear (for example, high-speed steel tools are easy to soften).
3
When processing pure copper, the chips are mostly in the form of "continuous strips". If the chips are not removed smoothly, they are likely to wrap around the tool or workpiece and scratch the processed surface. Copper alloy chips are relatively easy to break (for example, brass is mostly granular or short strips), so chip removal is less difficult.

FAQ
Q: What is your company's after service and warranty?
A: We make products according to drawings or samples strictly until them reach your 100% satisfaction. We'll be unconditional replace the poor products once get the confirmation of defected products within three months.
Q: Why choose us?
A: Our advanced 5-axis CNC machines and professional quotation staff ensure fast delivery time. We set order scheduling priorities based on demand and order complexity.
Q: Is it possible to know how the product is going on without visiting your company?
A: We will offer a detailed products schedule and send weekly reports with digital pictures and videos which show the machining progress.
Q: How long can I expect to get the sample?
A: Samples will be ready for delivery in 7-15 days for new mold products. The samples will be sent to you via express and arrive in 3-5 days. You can use your own express account or prepay us if you do not have an account.
Q: If I want to customize copper parts, what information do I need to provide?
A: You will need to provide key information such as 2D or 3D drawings, invoice information, materials, quantities, finishing and tolerance information.
