CNC Turning

CNC (Computer Numerical Control) turning is a machining process in which a rotating workpiece is shaped by a stationary cutting tool to produce cylindrical or symmetrical parts. The process takes place on a CNC lathe or turning centre, where the workpiece spins on its axis while the computer-controlled cutting tool moves along the surface, removing material to create specific diameters, tapers, grooves, threads, or other complex shapes.

CNC turning is ideal for producing round parts, such as shafts, bolts, nuts, and bearings. It provides high precision, repeatability, and efficient production, making it popular in industries requiring consistent quality and high-volume manufacturing.

At The Exact Group, our team of machinists produce components to high surface finishes, varying lengths, complex shapes and forms, as well as hundredths of a millimetre tolerances daily. Batch sizes range from one to 10,000 and you can be assured that our turning department will facilitate any of your needs or enquiries, regardless of size.

All parts go through rigorous testing and quality inspection using our Hexagon coordinate measuring machine, Mitutoyo Metrology and the innovative portable CMM Faro Arm.

Our turning facility at The Exact Group lends itself to a wide range of turning centres consisting of standard 2 and 3 axis lathes, right through to our 4, 5 and 9 axis turn-mills and sliding head capabilities.

The key benefits of CNC turning:

CNC turning achieves tight tolerances, essential for applications requiring exact dimensions and surface finishes.
The automated process increases production speed, especially for high-volume runs, and reduces lead times.
Computer-controlled movements ensure consistent quality across multiple parts, minimising variability and defects.
CNC turning can create complex geometry and detailed features, such as grooves, threads, and tapers, with high accuracy and repeatability.
Automation is cost efficient and reduces labour costs, and efficient material removal minimises waste, making CNC turning cost-effective for large batches.
CNC turning works with various materials, including metals, plastics, and composites, making it suitable for diverse industries.
CNC machines facilitate easy programming and quick tooling changes, allowing for flexibility in production runs.
Automation reduces the risk of accidents associated with manual machining.

The industries that use CNC turning:

Automotive: CNC turning is used to manufacture parts such as engine components, shafts, brake components, and other precision-machined parts.
Aerospace and Space: Essential for producing critical components like turbine blades, engine parts, landing gear, and other high-precision, complex components.
Medical: CNC turning is used to create medical devices and implants, such as prosthetics, surgical instruments, and orthodontic parts, which require high accuracy and biocompatibility.
Defence: CNC turning produces parts for military and defence equipment, including firearms, tanks, and vehicles, ensuring strength and precision.
Oil and Gas: CNC turning is used for making valves, pump components, and fittings, which must withstand harsh conditions and high pressures.
Energy: Components for wind turbines, power generation, and renewable energy equipment are often CNC-turned to ensure durability and efficiency.
Marine: CNC turning is used for producing parts such as propellers, shafts, and custom marine components that require high strength and precision.
