Cnc Turning

 What is the Cnc Turning?

Cnc Turning, lathe machining is a part of mechanical machining. Lathe machining mainly uses a turning tool to turn a rotating workpiece. Drills, reamers, reamers, taps, dies and knurling tools can also be used on the lathe for corresponding machining. Lathes are mainly used for machining shafts, discs, sleeves and other workpieces with rotating surfaces, and are the most widely used type of machine tool machining in machinery manufacturing and repair factories.


  • 1. It is easy to ensure the position accuracy of each machining surface of the workpiece;
  • 2. It is easy to ensure the verticality of the end face and the axis, which requires the verticality of the horizontal slide guide rail and the axis of rotation of the workpiece;
  • 3. Suitable for finishing of non-ferrous metal parts;
  • 4. The tool is simple, and the manufacturing, sharpening and installation of turning tools are more convenient.

What is the Turning Process?

TurningTurning is a valuable machining process that is used to shape the external surface of an object. Turning is achieved with the use of a specialized cutting tool and is typically used on materials such as:
  • Wood
  • Stone
  • Metal
  • Plastic
  • Composite materials
Turning is similar to the machining process called "boring” in which the cutting happens internally on the object. The cutting actions are so similar that turning and boring are usually grouped together into the same machining category.
The process of turning may be accomplished manually by passing a cutting tool such as a lathe across the surface of an object. Usually a machine will be used to turn the object while the cutting tool is applied to the surface. This results in uniform cuts of precise shapes and diameter. Turning often results in cylindrical shapes and the products can range in size from small to very large. Simple cutting edges are used to shape materials that can also be coned, curved or grooved.
Professional turning is achieved through the use of conventional turning machines or by using modern automated turning machines.

CNC Turning Companies

Turning services are generally available as part of a larger selection of machining services. These services will typically include full fabrication and welding services as well. The best machining companies will offer a comprehensive range of turning services available for materials from under one inch in diameter to nearly 300 inches.
The best machining companies will offer the latest technology and methods for CNC turning to produce exceptional quality components. These products should be of high tolerance with the company being able to meet requirements for unconventional shapes and sizes.
A large lathe inventory will allow machining companies to be able to accommodate mass production as well as any emergency requirements that arise. This may be accomplished through complementing a supply of CNC turning machines with conventional turning machines to provide additional production flexibility.
Discover the exceptional quality products that are possible with the help of experienced and highly skilled labour. Trust your CNC turning needs to a PTJ machining company today.
