CNC turning is a manufacturing technology that involves precision machining by means of a computer programme controlled lathe. It uses the relative motion between a rotating workpiece and a fixed tool to remove material to form the desired geometry. Compared to traditional manual turning, CNC turning offers a higher degree of automation, accuracy and repeatability, and is suitable for the mass production of complex parts

Key technical parameters in CNC turning machining
The reasonable setting of key parameters directly affects the machining effect:
Spindle speed (n)
Determine the appropriate cutting speed (vc) according to the diameter of the workpiece and tool material, and the calculation formula is generally:
Feed (f)
Depends on the tool, material and machining requirements, usually in mm/rev. A suitable feed ensures surface quality and tool life.
Depth of cut
The thickness of material removed per cut, which can be appropriately large for roughing and needs to be reduced for finishing to ensure dimensional accuracy and surface quality.
Backstroke (width of cut)
According to the rigidity of machine tools and cutting tools, a reasonable amount of backstroke can improve productivity, but too large may affect the surface quality.

Our various processing technology main production products include: equipment spare parts, product shells, mechanical parts, chassis cabinet shells and so on. These products are widely used in intelligent security, 3C, automotive, medical, smart grid monitoring and other fields.

Precision CNC machined parts, manufactured by computer-controlled mills and lathes, offer tight tolerances, consistent quality, and excellent finishes for demanding applications.

The technical data for CNC machined parts must include precise 2D drawings and 3D models, clearly defining all dimensional tolerances, GD&T, surface finish, and material specifications to ensure manufacturing accuracy and part quality.

CNC machined parts are critical components in high-tech industries such as aerospace, automotive, medical devices, and consumer electronics, providing the precision, complexity, and reliability required for advanced applications and prototyping.

CNC Turning is a manufacturing process in which bars of material are held in a chuck and rotated while a tool is fed to the piece to remove material to create the desired shape. A turret, with tooling attached is programmed to move to the bar of raw material and remove material to create the programmed result. This is also called “subtraction machining” since it involves material removal. If the center has both tuning and milling capabilities, the rotation can be stopped to allow for milling out of other shapes.

Turning specific operations (external)
Turning
Turning, the most fundamental of CNC operations, involves rotating a workpiece on a lathe while a cutting tool shapes it to the desired form. This process excels in producing cylindrical parts and is crucial in fabricating items such as shafts, pins, and rods. It’s marked by its ability to achieve high surface finishes and dimensional accuracy.
Hard turning
Hard turning is a specialized operation that focuses on materials with high hardness ratings. This process often replaces grinding and involves cutting materials that are hard to shape. It’s known for its precision and ability to achieve fine finishes on tough materials, making it a go-to for components requiring high wear resistance.
Taper turning
Taper turning is a technique used to produce conical shapes by gradually changing the diameter of the workpiece over its length. It’s essential for parts like cones and tapered shafts, offering a high degree of accuracy. This operation is critical for components that need to fit into specific angular spaces.
Facing
Facing involves removing material from the end of a workpiece to produce a flat surface. It’s often the first step in CNC turning operations and is crucial for preparing the ends of a piece for further machining. This process is vital for achieving precise face flatness and perpendicularity to the axis of the workpiece.
Grooving
Grooving in CNC turning is the process of cutting a groove into the surface of a workpiece. It’s commonly used for O-ring grooves, oil grooves, or where a specific recess is needed. The precision of CNC turning allows for exact groove dimensions, essential for parts requiring specific fits.
Parting
Parting, also known as cutoff, is the operation of cutting a workpiece through its diameter to separate it into two parts. This technique is used to create discrete components from a longer workpiece. It’s a critical step in the production of multiple parts from a single piece of material.
