FAQS

What parts can CNC turning make?

CNC turning produces cylindrical and symmetrical parts around their axis. This process is typically used for manufacturing items like shafts, pins, rods, bushings, and pulleys. It’s also well-suited for creating external threads, internal boreholes, and even complex contours on cylindrical surfaces. The precision of CNC turning allows for tight tolerances and a smooth finish, making it ideal for parts that require exact fits and movements, commonly found in automotive, aerospace, and manufacturing machinery.

Can you produce plastic turned parts?

Yes, CNC turning is versatile enough to handle various materials, including plastics. Plastics commonly turned on CNC lathes include ABS, Polycarbonate, PTFE (Teflon), Nylon, and Acetal. Each material offers different properties; for instance, Nylon is known for its strength and friction resistance, while Acetal provides excellent machinability and dimensional stability. Turning plastics requires precise control of cutting speeds and tool selection to prevent melting or deformation, ensuring the production of high-quality, precise parts suitable for a range of applications.

What’s the difference between CNC milling and CNC turning?

CNC milling and CNC turning are both subtractive manufacturing processes, but they differ in how the material is removed.


In CNC milling, the workpiece is stationary, and the cutting tool moves across multiple axes to remove material and create the desired shape. This process is ideal for complex parts with various features such as slots, holes, and contours.


On the other hand, CNC turning involves rotating the workpiece while a stationary cutting tool removes material. This method is best suited for producing cylindrical parts, such as shafts, rings, and bolts. While milling can handle more complex geometries, turning is typically faster and more efficient for producing round parts.

What is a CNC turning center, and what types of parts can it produce?

A CNC turning center is a computer-controlled machine designed to manufacture cylindrical parts with precision. It is capable of producing a wide range of components, including shafts, pins, screws, bushings, and other intricate parts. Highly versatile, the CNC turning center can perform various operations such as facing, turning, threading, grooving, drilling, and even complex contouring. Its advanced automation allows for consistent production quality and efficient handling of both simple and complex CNC turning parts across different industries.

How long does CNC turning take?

Lead time depends on part complexity, quantity, and material. Simple CNC turning parts can often be produced within a few days, while larger or more complex orders may require additional time.
