CNC Turning is a specific type of CNC Machining, referring to the particular subtractive machining process where the final piece, or material, is spun at high speed and a cutting tool shaves away material.
What does CNC means?
CNC stands for Computer Numerical Control and refers to the broader term for a manufacturing process led by a computer program. Parts are designed and developed using CAD (Computer-Aided Design). This CAD file will then be used to produce a computer program that will control the CNC turning machine, directing the cutting tools using long lines of code. The code or programming language is often in G-code format. This precise coding language allows CNC turning machines to make small and very precise cutting tool movements.
What is the process of turning?
Turning is the name given to the manufacturing process where bars of raw material are held and rotated at high speed. As the piece rotates, a cutting tool is fed to the piece, which works at the material, cutting away to create the desired shape. Unlike other cutting styles where the cutting tools themselves move and spin, in this case, the workpiece is rotated during the cutting process. 
CNC Turning is commonly used for cylindrical-shaped workpieces, however, it can be used for square or hexagonal-shaped raw materials. The workpiece is held in place by a ‘chuck’. The' chuck' spins at varying RPMs (rotations per minute).
Unlike a traditional lathe, today’s machines are numerically controlled. Often the turning process is under constant supervision and adjustment. Meticulous and exact results are possible due to the lathe being consistently monitored by a computer program. Modern CNC Turning machines have various tools, spindles, and speed capabilities. Additionally, the different sizes and shapes of the cutting tools themselves mean a wide range of geometries are possible. Tubular and circular shapes benefit the most from CNC Turning techniques.
Benefits of CNC Turning
CNC Turning is best if you are looking to create fast and repeated symmetrical or cylindrical parts with a high production volume.
CNC Turning can produce parts of high quality and an extremely smooth finish. CNC turning is also capable of:
- Drilling
- Boring
- Reaming
- Taper turning
What material is suitable for CNC Turning?
CNC machines can manufacture highly accurate, high-quality parts via subtractive machining technology. The materials that can benefit from CNC Machining include:
- Aluminium
- Steel
- ABS
- Titanium
- Copper
- PP
- PEEK
- Brass
- Nylon
