What is CNC Turning? The Ultimate Guide

Although CNC precision machining (computer numerical control) is a blanket term covering several types of automation-routers, EDM, plasma, etc . -CNC turning and CNC milling are the two most popular COMPUTER NUMERICAL CONTROL machines. Both engineering processes are essential, and, it’s safe to say, they could handle most of the work in a typical machine shop.

As a rule of thumb, think of the CNC lathe for round parts and the milling machine for all the flat function at the risk of oversimplifying the two CNC machining services. As with all other rules, there are exceptions, and some of the capabilities overlap, but it’s a good starting point.


As mentioned earlier, CNC turning services is actually a manufacturing process where a fixed cutting tool feeds into a metal bar held in a rotating chuck, removing material to produce the desired shape and size of the part. These trimming tools are mounted on a device turret and programmed to move to the pub to begin the engineering procedure. The raw materials used in turning operations is typically a circular club, but it could also be additional shapes.

On some CNC turning centers, a bar feeder moves the bar stock as each turned component is completed, while others have live tooling. This versatile feature allows for milling or adding radial or axial holes without eliminating the workpiece from the COMPUTER NUMERICAL CONTROL lathe.

Some CNC turning centers possess a single spindle, while others possess two spindles, a main and sub-spindle. The component can become partially machined on the main spindle and moved to the sub-spindle intended for extra procedures.

CNC lathes can become relatively straightforward, while others are highly complex to manage the the majority of complicated function. A high price tag will always accompany the latter, and programming them can end up being a time-consuming challenge.

These types of large CNC turning centers are impractical for smaller shops and hobbyists. Fortunately, there are options for the “ little guys ” with all the features they will need to stay competitive and productive.

What are the Fundamental Differences Between CNC Turning and COMPUTER NUMERICAL CONTROL Milling?

CNC turning machines have a rotating chuck or face plate where the workpiece is usually fastened. A set slicing device techniques into the revolving metallic piece, eliminating materials and creating a circular element. In contrast, CNC milling involves a workpiece secured to a movable table. In this case, the reducing gadget rotates and movements into the steel piece, getting rid of components and creating a flat surface.

COMPUTER NUMERICAL CONTROL turning and CNC milling also have many things in common. For example , they will both deal in geometries, tolerances, surface area finish, and CNC controls. Specific software regulates the motions of the CNC mill and CNC lathe, and, as a result, they each require highly trained and skilled workers at some stage in the machining procedure.

However, this article focuses on the COMPUTER NUMERICAL CONTROL lathe equipment, a remarkable machine application that has changed the dynamics of high-production and high-volume turning functions. With that in mind, here’s a detailed look at the CNC turning center, how it works, and the advantages this can offer to get almost any machine store.

Why Choose CNC Turning Services?

Purchasing a CNC horizontal turning middle sets up a machine store pertaining to previously unavailable opportunities. For instance, you could take upon rapid prototyping function and cut lead times to a fraction of what they were once. You could start competing on production runs meant for round precision machined parts and taper turning. Every operation imaginable, including threading, grooving, and knurling, will end up being completed efficiently on a COMPUTER NUMERICAL CONTROL turning equipment.

Although it takes a experienced worker to program and set up a CNC lathe, operating one is relatively simple. Companies can assign an entry-level employee to change parts while their skilled (and more extremely paid) employees are engaged in tasks commensurate with their talents.

In addition to the X-axis, Y-axis, and Z-axis on the primary three-axis COMPUTER NUMERICAL CONTROL turning middle, a few models feature up to 9-axis features. Considering the employee shortage in the creation industry, one competent programmer can now instruct a CNC lathe to do numerous procedures without getting rid of the portion. Machine shops could even turn to robotics to tend the machine.

What Parts Can You Produce about CNC Turning Machines?

As you may see, CNC turning methods create cylindrical parts such as shafts, pipes, spheres, cones, and parts with inner and outer diameters. Nevertheless, these versatile devices can also work, bore, knurl, drill, and tap with live tooling. And with the support of a headstock and tailstock, you can make long shafts that are accurate and have got an excellent surface area complete.

The versatility of the CNC lathe machine makes it an ideal fit designed for industries such as aerospace, automotive, medical, electronics, and the military, producing a range of products, from huge airplane engine parts to tiny surgical instruments.

Nevertheless, the majority of businesses are not involved in this level of production.

What if I Don’t Need the Sophistication of a Multi-Axis CNC Turning Center?

Most companies, self-employed machinists, and enthusiasts perform not need live tooling or the ability to exercise radial openings. They are looking for a durable COMPUTER NUMERICAL CONTROL lathe that allows them to consider on previously impossible projects. They want the accuracy and repeatability of a CNC lathe, and they require to eliminate the mess of coolant splashing from a manual lathe.

CNC Masters manufactures two CNC lathes, the 1340 and 1440 versions. The two devices allow businesses to keep job in-house that they had been formerly outsourcing to their competitors. They can expand their particular business to include creation operates, prototyping, and various various other COMPUTER NUMERICAL CONTROL machining solutions.

Each equipment tool enables a machine shop to switch to manual features when it makes more sense for a short run while maintaining the advanced CNC features for those high-production and difficult jobs.
