   - Milling Machines: Can process complex structures such as planes, grooves, and gears, and are widely used in mold manufacturing and the aerospace field.

   - Drilling Machines and Boring Machines: Drilling machines are used for efficient drilling, while boring machines are used to enlarge the aperture and improve the accuracy of the inner surface, which are commonly found in large - scale machinery manufacturing.

   - Grinding Machines: As finishing equipment, they significantly improve the surface finish and dimensional accuracy of workpieces and are suitable for the production of bearings, cutting tools, etc. with high - precision requirements.

 

2. Metal Forming Machine Tools

   - Forging Presses and Punch Presses: Through pressure, they cause the plastic deformation of metal billets and are used to manufacture automobile body parts, hardware tools, etc.

   - Bending Machines: Specialize in sheet metal bending and are used for the forming of building steel structures and household appliance casings.

 

3. Special - Purpose Machining Machine Tools

   - Electrical Discharge Machining Machines: Can process parts with high hardness and complex shapes, such as aircraft engine blades.

   - Laser Processing Machines: Complete cutting and punching with high precision and high speed and are suitable for the manufacturing of precision electronic components and medical devices.

   - Electrochemical Machining Machines: Conduct stress - free machining on special materials (such as titanium alloys) and are mostly used in the aerospace field.

 

4. Numerical Control Machine Tools

Automated machining is achieved through computer numerical control, combining high precision and high efficiency, and is especially suitable for the mass production of complex parts.
