What is CNC Turning Machining

CNC turning machining is a subtractive manufacturing process where a workpiece, typically cylindrical, is rotated against a cutting tool to remove material and create precise shapes and features. The process uses CNC (Computer Numerical Control) lathes, which automate the cutting operations based on programmed instructions (G-Code). The lathe spins the raw material held in a chuck, while the cutting tool moves linearly to shape the part. Common operations in CNC turning include facing, threading, knurling, drilling, boring, reaming, and taper turning. After machining, the finished part is separated from the stock material for further processing if needed.
This process is widely used for producing symmetrical parts with high precision and repeatability. CNC turning can handle a variety of materials, including metals like aluminum, steel, titanium, and plastics. It is ideal for manufacturing components with cylindrical geometries such as shafts, bushings, pins, and threaded parts. The process offers tight tolerances, often within ±0.001″ to ±0.005″, enabling the production of parts that meet stringent quality requirements.

CNC Turning Operations by KEMING

KEMING provides a wide array of CNC turning services including straight turning, taper turning, knurling, threading, grooving, and parting. We employ high-speed steel tools and carefully controls cutting parameters such as speed, feed rate, and depth to balance quality and efficiency, ensuring dimensional accuracy and surface finish meet design specifications.

Straight Turning

This operation uses cutting tools to uniformly reduce the diameter of a rotating workpiece, achieving a predetermined thickness. It is ideal for quickly removing material to prevent diameter variation and is often used as a rough machining step before finishing for dimensional accuracy.

Knurling

KEMING provides knurling operations that create textured patterns—such as serrated, angled, or intersecting lines—on the workpiece surface. This enhances grip by increasing friction, making it suitable for components like bolts and nuts. Special knurling tools are employed to achieve these patterns.

Segmentation Parting

This technique involves using a single-point cutting tool to cut deep grooves into the material, effectively separating parts or removing specific sections from the original workpiece. It is essential for producing individual components from a larger piece with precision and accuracy.

Taper Turning

KEMING’s taper turning operation gradually decreases the diameter of the workpiece from one end to the other by carefully angling either the cutting tool or the workpiece itself. This precise process produces conical shapes that are commonly required in various automotive and machinery parts.

Threading

We perform threading by carefully moving the cutting tool along the length of the workpiece to cut precise spiral grooves on its external surface. This process creates threads with a specific pitch and length, which are essential for reliable fastening applications in various mechanical assemblies.

Grooving

This machining operation involves creating narrow or wide grooves on the surface of a workpiece by employing sharp cutting tools. It is specifically used to produce grooves with precise widths and depths, which are crucial for various mechanical functions and assembly requirements.

CNC Turning Materials by KEMING

Keming, a CNC turning parts manufacturer based in China, works with a variety of materials commonly used in CNC turning processes. Their materials include metals such as aluminum, brass, stainless steel, steel, copper, titanium, and nickel, which are chosen for their strength, hardness, and conductivity. These metals are widely applied in industries like aerospace, automotive, and machinery manufacturing.
In addition to metals, Keming also machines plastics and composite materials such as carbon fiber and glass fiber, which are valued for their lightweight, high strength, and rigidity. Plastics used include types with good wear and corrosion resistance, suitable for electronics and communication equipment. Composite materials require special tooling and parameter control to avoid damage during machining.

Metals for Custom CNC Turning

Aluminum: Aluminum alloys (such as 6061, 7075, and 5052) are highly favored for CNC turning because they are lightweight, strong, corrosion-resistant, and very malleable. They allow for intricate shapes and smooth finishes, making them ideal for aerospace, automotive, medical, marine, and electronics industries.
Low-Carbon Steels: Grades like 1018 and free-machining steels such as 12L14 are excellent for CNC turning due to their good machinability, ductility, and affordability. They produce manageable chips and are often used for shafts, rods, screws, and pins where moderate strength and ease of machining are required.
Alloy Steels: Alloy steels such as 4140 and 4340 are selected for parts requiring higher strength, hardness, or toughness. These are often achieved through specialized heat treatment processes. With moderate machinability, alloy steels are widely used in manufacturing critical parts such as spindles, bolts, and various aircraft components.
Stainless Steels: Common stainless steel grades like 304, 316, and 17-4 PH are used for their excellent corrosion resistance and good strength. They have good to moderate machinability and are suitable for manufacturing food processing equipment, marine components, turbine parts, and various types of industrial tools.
Copper: Copper is widely chosen due to its outstanding electrical and thermal conductivity. Additionally, its good malleability allows it to be easily shaped into complex forms. These properties make copper an ideal material for electrical contacts, heat sinks, wiring, and various intricate components in electronics and engineering.
