What is metal turning?

Metal turning is a form of machining that involves removing unwanted material from a workpiece. The process requires a lathe with a cutting tool and a workpiece.
The workpiece is a piece of machined material attached to the chuck of the machine, rotating at high speed.

The cutter is usually a single-point cutting tool attached to the machine. The cutting tool is brought closer to the workpiece, thereby cutting away some of the material in the form of chips, until the desired shape is achieved.

Turning is used to produce rotating parts with features such as holes, gouges, threads, tapers and various degrees of diameter.
Turning can be used as a downstream process to refine parts produced by other processes.

CNC turning is an innovative and modern form of workpiece machining due to the computer aided process. This makes it possible to obtain a large number of the same final parts in a short time, distinguished by high quality.

What is CNC turning?

In general terms, CNC turning is a specialized manufacturing process that involves machining a given material. In this process, the workpiece material is held by a chuck and rotated around an axis. During this time, the cutting tool (knife) is pushed against the material in order to remove (cut) the superfluous part of the material and, as a result, obtain the desired shape. The key in CNC turning is to move the cutting tool along the material in such a way that the desired result is achieved.

The material being machined can be (and generally is) round, although square or hexagonal materials are also common. The length of material to be machined can vary and depends on the capabilities of the machine tool.

Each CNC lathe has its own set of computer-controlled tools. The more tools the machine has, the greater the number of options for machining the material.
Some CNC machines can stop the rotation of the workpiece at any time to perform additional functions such as:

  • drilling holes;
  • drilling slots;
  • surface milling.

The material turning services performed by our company include precision turning. A wide range of modern CNC lathes allows us to produce parts from a variety of materials. We offer a combination of knowledge and the latest technology, which allows us to obtain products with tight tolerances. This allows us to produce efficient products with high quality.

Milling vs CNC turning - similarities and differences

The milling and turning services we offer have some differences. Since these services are seemingly similar, and our customers sometimes confuse them, we present a description of both. What is the difference between machining: milling and turning?

CNC milling is done with a numerically controlled milling machine. It uses commands written in the form of a computer program. Each code entered into the program is responsible for a specific function performed by the machine. Once all the codes have been entered into the CNC program, the purpose of which is to machine the prepared material, it is not the material but the milling cutter that rotates. It rotates along its axis and cuts and shapes the material upon contact. The purpose of processing is to fit the material to the dimensions in accordance with the written computer program. A CNC milling machine can be controlled in two ways: by computer or manually.

  • Computer control allows the machine to make precise cuts required by the user.
  • Manual control allows the operator to control (slow down or speed up) the production process.

CNC turning is different from milling. It is also based on computer programs, but here a slightly different end product is created. In this process, the cutting tool is moved parallel to the work piece. However, in this case it is the material that is rotated at a set speed, while the cutting tool moves to create incisions of precise depths and diameters.
CNC turning can be used on the outside of the material to achieve a circular shape or on the inside to create a circular recess in the material. Due to the significant automation of the CNC turning process, it can be completed faster and more accurately than manual lathe turning.

Aluminium turning

Turning aluminum is not difficult, but when doing so, remember to rotate the material at high speed. A certain turning principle is to select the turning speed in relation to the hardness of the material. The harder the material, the slower the rotation speed. Since aluminum is a soft material, the rotation speed of the lathe should be very high. Depending on the lathe you are using, you may need to use maximum speed. Be aware that when turning a long piece of aluminum, you may experience problems with a wobbly tip. It should then be assumed that it is impossible to machine an object longer than three times its diameter accurately enough.

Copper turning

CNC copper machining is the specialised machining of copper components from customer-designed blanks, semi-finished copper products or rods. Unfortunately copper is a very difficult metal to machine, and its machining requires specialized knowledge of the process. To improve machinability, copper alloys are often used instead of pure copper, especially when complex work is to be done to order. For such machining the necessary knowledge and experience in copper machining is essential.

Plastic turning

The machining and turning of plastics requires experience and specific machining processes due to the tight tolerances. Components such as bearings, bushings, seals and guides must be manufactured with high precision. That is why in practice we process these parts with care, thanks to our experience in turning plastics.

Polyamide turning

Turning polyamide is a difficult process, just like turning plastics. It requires a lot of knowledge and experience, but years of work allowed us to gain it and deal with this processing.

Stainless steel turning

Practice shows that low carbon steel is softer and easier to machine than alloy steel. The machinability of a material depends on its hardness, so hardness is a very important characteristic to consider when calculating the feed rate. Stainless steel is an alloy steel and the alloying element is usually chromium. It forms an oxide on the surface, which increases the corrosion resistance of the material. Other types of alloying elements such as nickel and carbon are also used in the production of stainless steel. The alloying elements differ from one another. Stainless steels are therefore not only characterized by a high degree of hardening, but also by a low heat transfer coefficient.

Shaft turning

One of the typical technological operations performed on a machine tool is the turning of external cylindrical surfaces. For this activity lathes are used, which allow obtaining rotating solids. Thanks to the possibilities of modern CNC lathes, it is possible to carry out very precise metal processing, thanks to which it is possible to obtain, among others, shafts.
