CNC lathes for machining fittings
CNC lathes for machining complex contours without programming knowledge
Portable CNC lathes for the repair of permanently installed fittings have been around for a long time. However, only simple shapes are possible. If you want to machine complex shapes, you need a CNC control, which usually requires complex programming. EFCO has developed portable CNC lathes with convenient controls that can be easily operated by the user. This makes maintenance more flexible, cheaper and faster.
Transportable CNC lathes (TD CNC series)
The CNC lathes in the EFCO CNC series open up almost unlimited possibilities for turning surfaces. With our machines, we achieve a whole new level of quality in the machining of flanges and valve seats.
Thanks to the pre-programmed processing cycles, our CNC lathes from the TD CNC series are immediately ready for use and can be operated after just a short training session. Previous knowledge of CNC programming is not required. Of course, it is also possible to expand the program package with your own CNC programs.

CNC lathe for transportable flanges (TDF CNC series)
Our CNC lathes from the TDF CNC series are optimized for the turning of flanges due to their low overall height and large axial stroke. The robust design makes them ideal for axial grooving and groove machining.
CNC lathe for stationary valve machining (PDM series)
PDM machines are designed for the axial machining and facing of fitting housings (gate valves, valves, check valves), pumps and similar rotationally symmetrical components.
They have infinitely variable speed control and axial and radial feeds (Z and X axis) with infinitely variable control that make it possible to move both axes simultaneously at different speeds.
Stationary CNC lathes for fittings (SPM machining center)
The optimum solution for the complete machining of fittings, for general overhauls as well as for use in production! CNC lathes in the SPM series have precision tilting tables (±12°, accuracy ±10") and have been optimized for the efficient machining of fittings.
Thanks to the flexible design of the CNC lathes, they can also be used for other machining tasks.

What types of CNC lathes are there?
CNC lathes belong to the category of metal-cutting machine tools. They are mainly used for shaping metal (or other materials) through the turning process. A CNC lathe is a high-precision machine that is computerized and used for turning metal parts and other materials. CNC stands for "Computerized Numerical Control", which means that the movements of the machine are controlled by computer programs. This technology makes it possible to produce complex shapes and designs with high precision and efficiency.
CNC lathes differ in their configuration, size and functions. Depending on their design, they offer specific advantages and are ideally suited to certain machining tasks and workpiece types. The choice of the right machine depends on the specific requirements of the manufacturing process.

- Horizontal lathes are the most common type of CNC lathes. With this type of machine, the workpiece is clamped horizontally and turned. They can be used for a variety of turning tasks and are suitable for a wide range of applications.
- Vertical l athes or vertical lathes have a vertically aligned spindle. This configuration makes them ideal for turning large and heavy workpieces. The design facilitates the loading and unloading of the workpieces to be turned.
- Turn-mill centers combine turning and milling functions in a single machine. The machining of complex parts with different operations is possible with these systems without reclamping the workpiece. As a result, they offer a high degree of flexibility and productivity for all turning operations.
- Swiss-type lathes are referred to as sliding headstock automatic lathes. This type of CNC lathe is designed for the precision production of small parts. They are particularly suitable for turning long, slim workpieces.
- Multi-spindle automatic lathes are CNC lathes that have several spindles. This type of machine shortens the machining time enormously, as different turning operations can be carried out simultaneously on one workpiece. They are ideal for turning in mass production.
- The counter-spindle lathes have an additional spindle (counter spindle). It enables these CNC lathes to machine a workpiece from both ends simultaneously. This reduces the machining time during turning and improves precision.
What steps are involved in CNC turning?
When working with a CNC lathe, various steps must be taken into account. From planning and programming to the actual machining and subsequent inspection of the turned part. Working with a CNC lathe requires expertise in both programming and machine operation in order to efficiently produce high-precision parts. Here is an overview of typical CNC turning workflows:
- The process begins with the design of the part to be turned. This is usually done using computer-aided design (CAD) software, which is used to create a digital 3D model of the workpiece. This completes the design and CAD modeling.
- Once the design has been defined, the CAD model is imported into a CAM (computer-aided manufacturing) program. This is where the manufacturing process is planned by generating tool paths for turning. The CAM program determines which turning tools are used. It also programs the sequence of machining steps and specific parameters such as speed, feed rate and cutting depth.
- The data created in the CAM program is then converted into a CNC program that is used in the machine control. This can be G-code or another machine-specific format. G-code is a programming language that gives CNC lathes instructions for tool movements and other control information.
- Before machining can begin, the CNC lathe must be set up. This includes setting up the tools in the tool turret, clamping the raw material or workpiece in the clamping device and setting the reference points. This is a prerequisite for the machine to know exactly where the workpiece is located.
- As soon as the CNC machine has been programmed and set up, machining can begin. The CNC lathe follows the programmed instructions to turn the workpiece. Automation enables very accurate and consistent machining, even with complex shapes and patterns.
- After machining, the turned part is checked to ensure that it meets specifications. This can be done by manual measurements or with precision measuring equipment such as coordinate measuring machines.
- If necessary, additional steps such as grinding, polishing or coating are carried out after the initial CNC machining. The workpiece is thus completed or given a special finish.
What does a CNC lathe cost?
The cost of a CNC lathe can vary greatly. The acquisition costs depend on several factors such as size, precision, functionality, manufacturer and additional features such as driven tools, Y-axis, counter spindle or automatic workpiece loader. For companies looking to invest in a CNC lathe, it is not just the acquisition costs that are important. Rather, the operating and maintenance costs must also be taken into account. We have listed some general price ranges here:
- You can getentry-level models and compact machines for as little as €20,000 to €60,000. These CNC lathes are often suitable for small to medium-sized workpieces and for training purposes, hobby workshops or small batch production.
- CNC lathes in the medium price range cost between 60,000 and 150,000 euros. If medium to high quantities are to be turned, these machines offer greater precision and more functionalities.
- High-performance and multi-purpose CNC lathes are available for an investment of over 150,000 euros up to several million euros. For these costs, you get specialized or very large machines that are designed for demanding production tasks and offer functions. For example, they have simultaneous 5-axis machining for turning work in mass production. They are used where maximum precision and efficiency are required.
- In addition to the purchase costs of a CNC lathe, there are further expenses. In particular, there are costs for programming and design software (CAD/CAM) or costs for installing the CNC lathe and training personnel.
- Recurring costs for regular maintenance and potential repairs must always be taken into account. There are also regular costs for additional tools, clamping devices and other accessories.
