What Is CNC Turning?

 

 

CNC turning is a machining process where a cutting tool, typically a non-rotary tool bit, moves linearly while the workpiece rotates. The operation is performed on a CNC lathe or turning center, where the raw material is held in a chuck and rotated at high speeds. The cutting tool removes material from the outer diameter or inner diameter (in the case of boring) of the workpiece, shaping it into the desired form.

 

Key characteristics of CNC turning include:

 

• Rotation of the Workpiece: The workpiece spins around its axis.
• Stationary Cutting Tool: The cutting tool moves in a linear path along the workpiece.
• Cylindrical Parts Production: Ideal for creating components with rotational symmetry.
• High Precision and Speed: Capable of producing precise CNC turned parts efficiently.

 

Common products made through CNC turning are shafts, bushings, knobs, pulleys, and other cylindrical components.

 

 

 

 

 

 

 

 

How CNC Turning Works？

 

 

In CNC turning, the process begins with securing the workpiece in the chuck of a CNC lathe. The lathe spins the workpiece at a predetermined speed, while a stationary single-point cutting tool moves along axes to remove material and shape the part.

 

Process Steps:

 

• Mounting the Workpiece: The raw material is clamped into the chuck.
• Programming the CNC Machine: Instructions are fed into the CNC control unit, dictating tool paths, speeds, and feeds.
• Rotating the Workpiece: The lathe spins the workpiece at high speeds.
• Material Removal: The cutting tool advances along the workpiece, removing material to achieve the desired diameter and shape.
• Finishing Operations: Additional processes like threading, knurling, or drilling may be performed.
• Part Removal: Once machining is complete, the part is removed for inspection and finishing.

 

 

Key Points:

 

• Axes Movement: Typically involves X and Z axes; some advanced lathes include Y-axis movement.
• Tool Turret: Holds multiple tools for various operations without the need to change setups.
• Precision Control: CNC systems allow for tight tolerances and repeatability.
