cnc brass machining parts

Numerical control machining common machining methods are turning, milling, grinding, boring, drilling, wire cutting, EDM, etc.


Tube machine tools are large or small, simple or complex, can be divided into five categories, the five categories are the five basic methods of metal forming, mechanical processing has five methods of drilling, turning and boring, milling, grinding and planing, the characteristics of these processing methods are as follows:

1. drilling

Drilling is the process of drilling holes into solid metal. A rotary bit called a twist drill is used. The machine tools used to drill holes are called drill presses. Drilling machines also have a variety of models and specifications. In addition to drilling, drilling machines can also carry out other processing. When drilling, the workpiece positioning clamping, fixed; The drill drills into the workpiece as it turns.

2. Turning and boring

Ordinary machine tools are the most common machine tools used for turning workpieces. Turning is the process of cutting metal from a workpiece. The tool cuts into or turns along the workpiece as it rotates.


Boring is the processing method of enlarging or further machining holes already drilled or cast in the metal workpiece. Boring on a lathe is done by turning the single-edge tool on one side and feeding the workpiece on the other.

3. milling

Milling is the process of cutting metal using a rotating tool, which has multiple cutting edges, known as milling cutters.

4. grinding

Grinding is a process of cutting metal using a grinding wheel called a grinding wheel. The workpiece is finished by grinding. The workpiece size is accurate and the surface is smooth. When grinding a circular workpiece, the workpiece rotates on one side and feeds to the rotating grinding wheel on the other. When grinding a flat workpiece, the workpiece moves back and forth under the rotating grinding wheel. The grinding process is often used for the final finishing of a hard, heat-treated workpiece to a precise size.

Copper classification and common processing methods

The purity of copper is the main distinction, electrolytic copper is general purity is higher. Pure copper is suitable for stretching, anaerobic copper is suitable for wire network cable and other cables


Other copper materials are mainly copper alloys, copper and zinc, tin, lead, and other alloys.


Alloy hardness rise, such as copper-zinc alloy brass copper content higher such as 62%, suitable for grinding, cutting, drilling, gouging. But it's not good for stretching


Copper-lead alloy is suitable for sculpture
