What is CNC Turning?
CNC turning is a process where a computer-controlled lathe rotates the workpiece while a cutting tool shapes it into cylindrical parts. The workpiece is fixed on a rotating spindle, and as it spins, the tool moves along its length based on the programmed design. This process can include threading, grooving, and drilling while maintaining high precision and smooth finishes.
What's the Features of CNC Turning?
· Efficient Production: Suitable for high-volume production with consistent results.
· Versatile Machining: Capable of performing multiple operations like threading, grooving, and drilling.
· Smooth Surface Finish: Provides excellent surface quality, reducing the need for additional finishing processes.
What's the CNC Turning Typical Applications
CNC turning is widely used for manufacturing cylindrical parts such as shafts, bushings, threaded components, and complex rotational geometries, covering industries like automotive, aerospace, electronics, plumbing, and industrial machinery.
CNC Turning Processing Classification
- By processing type
- External Turning: Machines outer surfaces, ideal for shafts.
- Internal Turning: Creates internal holes, like in bushings or sleeves.
- Facing Turning: Cuts end faces to adjust length and finish.
- Thread Turning: Produces threads for bolts, nuts, and similar parts.
- By Shape and Geometry
· Cylindrical Turning: Regular machining of cylindrical parts, such as shafts and tubular components.
· Taper Turning: Machining of tapered parts, such as conical tubes and taper shafts.
· Spherical Turning: Used for machining spherical parts, such as ball valves and spherical joints.
- By Equipment Type
· Single-Axis Lathe: Ideal for simple shapes like cylindrical parts.
· Multi-Axis Lathe: Handles complex shapes and multiple tasks, reducing setups.
· Mill-Turn Machine: Combines turning and milling for complex parts in one setup.
