Automatic turning machines for metalworking
How automatic turning machines work
An automatic turning machines is a high-precision machine that is indispensable in the modern manufacturing industry. These automated machine tools are designed to machine complex parts with high precision and efficiency. By combining speed, precision and automation, automatic turning machines are revolutionizing manufacturing processes by increasing productivity and reducing manufacturing costs.
At the heart of an automatic turning machines is its computerized numerical control (CNC) system, which precisely controls the movements of the tool and the workpiece. Users can enter detailed programming instructions that control the entire machining process from material feed to final cut. This CNC technology enables the automatic turning machines to produce complex shapes and designs with exceptional accuracy.
The functional sequence of an automatic turning machines begins with the component geometry-specific programming of the NC program. This is where the operator defines the exact parameters, such as the turning speed, the direction of movement of the tool and the cutting depth. Once the NC program has been transferred to the machine's CNC control system, the raw material is clamped in the machine (chuck, chuck parts) or fed as bar stock through the main spindle. The automatic lathe then activates the cutting tool (cutting precision tool), which moves along predefined paths to remove chips and thus shape the workpiece to the desired form.
Turning machine or automatic turning machine?
The main difference between an automatic turning machine and a turning machine lies in the automation and complexity of the machining processes. A traditional turning machine is operated manually and is ideal for simple turning work and smaller series. In contrast, an automatic turning machine offers fully automated processes that enable complex and precise machining.
Cam-controlled automatic turning machines are characterized by mechanical control by means of cams, which enable precise machining without computer support and are particularly advantageous for smaller series production.
CNC automatic turning machines are equipped with advanced computer controls that allow high-precision production of complex parts with minimal human intervention. This makes them ideal for mass production and demanding manufacturing tasks.
The choice between an automatic turning machine and a turning machine therefore depends on the required precision, complexity of the parts and production volume.
Areas of application for automatic turning machines
Thanks to advanced software and precise hardware, automatic turning machines can machine a wide range of materials, including metal, plastic, and wood. They are used in numerous industries such as automotive, aerospace, mechanical engineering and medical technology. Their ability to produce complex parts quickly and with consistent quality makes them an indispensable part of modern manufacturing technology.
Types of automatic turning machines
There are different types of automatic turning machines in industrial manufacturing, each with specific advantages for certain requirements.
Fixed head automatic turning machine
A fixed head automatic turning machine is optimized for the fast and precise machining of short and compact workpieces. These machine tools are ideal for the production of parts with small length to diameter ratios, such as screws, nuts, and complex geometries used in the automotive, electronics and medical industries. The ability to quickly switch between different machining operations makes them particularly valuable for mass production and for companies that require a flexible manufacturing solution for a wide range of products.
Sliding head automatic turning machine
A sliding headstock automatic turning machine specializing in the precision production of long and slender workpieces is revolutionizing metalworking with its efficient and precise operation. At the heart of this machine is the ability to guide and support the workpiece during the turning process, enabling the production of workpieces of great length in relation to diameter. Unlike conventional turning machines, where the workpiece is clamped in a fixed position, with sliding headstock automatic turning machines the material moves through the machine while the cutting tools make precise cuts. This minimizes vibrations and improves the surface quality. An automatic turning machine with bar feeder is often used, where the raw material is fed in bar form through the main spindle and clamped. Sliding headstock automatic turning machines are ideal for complex parts such as medical instruments, electronic components and automotive parts.
CNC multi-spindle turning machine
With several spindles that can carry out different machining operations simultaneously on a workpiece that is passed on in cycles, this machine tool is perfect for the fast production of complex parts in large quantities. The CNC multi-spindle turning machinemulti-spindle turning machine is primarily used in industries where the focus is on precision and short throughput times. Simultaneous machining significantly increases efficiency by minimizing the total machining time for each part. Multi-spindle turning machines are therefore ideal for companies that require high-volume production of precision parts with strict tolerances and high quality standards. A 6-spindle automatic turning machine is often sought after.
Advantages of automatic turning machines
Automatic turning machines offer significant advantages over other methods in metalworking. Their high-precision CNC technology enables the production of complex shapes with exceptional accuracy and repeatability, which is difficult to achieve manually. Compared to conventional machining methods, automatic turning machines increase efficiency and productivity through fast production cycles and minimal set-up times. They are able to operate 24/7, which shortens lead times and increases production capacity. Their versatility allows them to machine different materials, making them a cost-effective solution for a wide range of industries, including automotive, aerospace and medical.
Control of automatic turning machines
The programming and control of an automatic turning machine, especially a CNC-controlled one, is carried out using specially developed software that allows detailed instructions and machining parameters such as cutting speed, speed and feed rate as well as the tool path to be entered in order to create the desired component geometry. The operator programs the machine by entering the code or by using graphical user interfaces (CAM systems, post-processor) that simplify the creation of complex programs. These digital programs then precisely control the movements of the tool and the workpiece to produce high-precision parts. State-of-the-art technologies also make it possible to monitor and adjust machining processes in real time, which increases the efficiency and quality of production.

Choosing the right automatic turning machine
Several key features and specifications are decisive when purchasing an automatic turning machine:
- The maximum turning length and the turning diameter determine the size of the workpieces that can be machined.
- The maximum bar passage diameter defines the maximum size of the manufactured components.
- The spindle speed and power influence the machining speed and precision.
- The number of tool stations defines the versatility of the machine for different machining operations.
- Equally important is the CNC control for intuitive programming and control.
- Pay attention to the robustness and build quality for longevity. Compatibility with existing tools and systems in the manufacturing process.
- Finally, service and support from the manufacturer should be considered in the decision-making process.
