Precision machining mainly requires high-precision CNC machine tools, five-axis machining centers, precision grinding machines, and mill-turning centers. These machines can achieve micron-level or even nanometer-level machining accuracy, meeting the needs of high-end manufacturing fields such as aerospace, medical devices, and semiconductors.
Based on the machining object and process requirements, commonly used equipment can be divided into the following categories:
CNC Lathe:
Used for machining rotating parts such as shafts and discs, with a machining accuracy of 0.004–0.01 mm. Widely used in the production of new energy motors and medical imaging equipment components.
Machining Center:
Includes vertical, horizontal, and five-axis machining centers. Capable of multi-faceted and multi-process composite machining, particularly suitable for complex curved surfaces and high-precision structural parts, such as aircraft engine blades and robot joint components.
Precision Grinding Machines:
Such as high-precision cylindrical grinders, coordinate boring machines, and optical grinders, used for ultra-precision machining of rough-machined parts, achieving surface roughness below Ra 0.01μm. Commonly used for the final machining of gears, bearings, and guide rails.
Specialized Machining Equipment:
Electrical Discharge Machining (EDM): Suitable for machining hard and brittle materials or complex cavities, without direct contact with the workpiece.
Wire Cutting Machine: Uses molybdenum wire to cut conductive materials, suitable for machining micro-holes and narrow slits.
Laser Cutting Machine: Achieves non-contact, high-precision cutting, widely used in sheet metal and microelectronic device processing.
