What is CNC machining？

CNC machining has infused new vitality into various industries. As costs decrease, many cast parts have shifted to CNC machining to achieve higher quality and precision. CNC machining is a key technology in modern manufacturing, enabling high-precision and efficient metal processing through computer-controlled automation. The main techniques involved in CNC machining include cutting, milling, drilling, turning, grinding, and wire cutting.

Cutting

Cutting is one of the most common processes in CNC machining. With CNC machine control systems, tools cut the metal material along a predetermined path, removing excess material to shape the workpiece to the desired form and size. Cutting processes include:

• Turning: Primarily used for machining rotating parts. CNC lathes rotate the workpiece and move the tool to achieve shapes like cylinders, cones, and threads.
• Milling: Uses a multi-tooth cutter to cut the workpiece, suitable for machining planes, grooves, teeth, and other complex shapes. CNC milling machines can perform three-axis, four-axis, or even five-axis machining, greatly enhancing flexibility and efficiency.
• Drilling: Used for machining holes. CNC drilling machines can precisely position and process multiple holes, improving production efficiency and hole accuracy.
• Boring: Used to enlarge and finish existing holes, achieving high-precision inner hole machining through precise tool path control.

Grinding

Grinding is a high-precision surface machining process that uses abrasive tools (such as grinding wheels) to remove small amounts of material from the workpiece surface. CNC grinders can precisely control grinding parameters to achieve high surface quality and dimensional accuracy, widely used for surface treatment of precision parts and machining hard materials.

Wire Cutting

Wire cutting uses electrical discharge to erode metal material, enabling the machining of complex contours and fine details. CNC wire cutting machines use thin metal wires (typically molybdenum or brass) as electrodes to perform discharge cutting along a predetermined path. Wire cutting is suitable for machining hard alloys, mold steels, and other difficult-to-machine materials, achieving extremely high machining precision and surface quality.
