CNC turning
For CNC Turning it is an automated Production method for the production of rotationally symmetrical components. The process offers far-reaching advantages over conventional production on a rotary bench and is predominantly used in the metal processing industry.
CNC lathe is characterized by a high degree of automation and convinces above all by a high repeatability as well as the possibility to efficiently manufacture even complex rotationally symmetrical geometries. The range of applications of CNC lathes is diverse and ranges from the production of CNC lathes for the automotive industry and machine and plant construction to the production of small parts for medical technology and electrical engineering. Both small and medium series and large series can be manufactured economically by CNC machining.
What does CNC mean?
CNC stands for “Computerized Numerical Control” and refers to a control technology used in modern industrial machining centers for the automatic production of complex components. Usually, the development process for producing a CNC turning part begins with the computer-assisted construction of the workpiece by a CAD software.
Following the design, a CAM system from the CAD data can generate a CNC code by taking into account the relevant parameters such as the geometry of the tools used, the feed speeds and the rotational speeds. This CNC program code can then be used in a CNC lathe for the production of the component, wherein continuous support by personnel is not required. Modern machining centers are able to perform the entire manufacturing process automatically from fitting through tool change to monitoring and quality control. This high degree of automation results in a high economic efficiency for the company, especially in series production.

During the manufacturing process, the relevant setpoint specifications are continuously monitored by the lathe. These include, for example,:
- Position of tool (position)
- Speed of chipping
- Position of the tool spindle
- Speed of rotation of the tool spindle
- coolant supply
- Material supply/stang loader

Technical Basics of CNC Turning
Like conventional turning, CNC turning is also based on cutting machining of a rotating workpiece by a tool, the cutting edge. In a CNC machine, the workpiece is first clamped, rotated and then processed with different tools in a fixedly programmed sequence. Modern machining centers provide a variety of different tools such as indexable inserts, drills or thread cutters and can change them independently to produce the desired workpiece geometry.

In principle, a distinction is made between the internal and the external turning, wherein a CNC lathe can take over both lathes. In addition, depending on the feed direction, the rotary methods are subdivided into the transverse rotation and the longitudinal rotation.
Depending on the processing surface, further classifications are performed. For example, experts speak of
- Screwdrive
- Roller turning
- Round turning
- Form turning
- Turning
- Profile rotation
Since a large part of the applied energy is converted into heat during the cutting operation, a cooling system is required to ensure a stable temperature. CNC lathes frequently have modern cooling lubricant systems which feed the coolant under high pressure directly to the contact zone between cutting edge and chip. The quantity of the supplied coolant is also varied as a function of the processing intensity.
The range of applications of CNC turning is diverse and includes a wide range of rotationally symmetrical components used in a wide variety of industries. These include:
- Axles
- bolts
- Waves
- Flanges
- Discs
- Rings
- Mothers

Advantages of CNC turning
CNC turning has proven itself in the metal and plastic processing industry and convinces with a number of advantages. These include:
- Productivity:
Due to the high degree of automation, productivity can be achieved primarily in series production
significantly increase compared to conventional turning. - Reproducibility:
CNC turning allows the company to produce high numbers of pieces with the same quality. - Attrition
The computer-assisted control of the tools makes wear less than conventional turning. - Plantability:
Unlike manual turning, the manufacturing times during CNC turning can be precisely predicted. - Complexity:
Modern CNC machining centers are able to produce components with highly complex geometries. - Preparation systems:
Modern CNC lathes can be connected to each other, to coordinate production processes and further increase productivity.
