What is CNC Turning?

CNC turning is a subtractive method that involves the use of rotating chucks and stationary cutting tools to shape parts. It is particularly suitable for creating symmetrical parts along their center axis. In CNC turning, a blank bar of material is loaded into the chuck of the lathe’s spindle. The spindle holds the workpiece in place while it rotates. Once the spindle reaches its desired speed, a stationary cutting tool is brought into contact with the workpiece, gradually removing material until the desired shape is achieved.

After all machining operations are completed, the finished part is cut from the stock material for further processing. The CNC lathe can then repeat the operation with minimal setup time. The main objective of CNC turning is to machine parts with shapes that can be formed by cutting into a rotating bar of raw material.

CNC Turning FAQs

In CNC turning, a computer program controls the CNC machine, which moves the cutting tool along the rotating workpiece. The program specifies the toolpath, cutting speed, and other parameters to create the desired part.

Yes, CNC turning can handle complex geometries by using specialized tooling and multi-axis machines. It can create features such as threads, grooves, and intricate contours with high precision.

CNC turning centers provide the flexibility to incorporate rotating cutters like end mills or drills. This feature allows the machine to handle asymmetrical features in parts, increasing machining freedom. CNC lathe machining also ensures ease of achieving radial symmetry, superior precision, and the ability to achieve a smooth surface finish.

When selecting a CNC turning service provider, consider factors such as their experience, equipment capabilities, quality control processes, lead times, and pricing. It's also important to review their portfolio and customer reviews to assess their reliability and quality of work.
