Efficient Solutions for Industrial Needs
CNC lathe CLS – Series
Precise and efficient CNC milling machine suitable for versatile machining. Robust construction and FANUC control system ensure high-quality results.
CLS20 Beveled Spindle Milling Machine
DMTG CLS20 is a modern and efficient CNC milling machine designed specifically for precision metalworking. The machine’s structural foundation is its robust cast iron frame, implemented using a 45-degree bevel design. This bevelled frame makes the machine extremely rigid and stable, which is crucial for minimizing vibrations during machining. At the same time, the structure ensures that chips and coolant generated during machining easily remove from the working area, improving operational reliability and keeping the machine cleaner.
The machine’s movements are based on high-quality linear guides and directly coupled servo motors. This technical implementation ensures that the tool movements are not only fast but also extremely accurate. In practice, this means excellent repeatability, allowing each manufactured part to be identical in size to within thousandths of a millimeter. Fast positioning movements significantly reduce the waste time between machining operations, making production efficient.
In terms of performance, the CLS20 is a highly versatile tool for machining various parts. It is excellent for both machining long, axially-shaped parts and larger, disc-shaped parts. The machine’s spindle’s high rotational speed and powerful motor allow for both light finishing and heavy-duty roughing. Furthermore, the machine’s through-spindle bore allows for the use of shank loading devices, further automating production.
Ease of use and modern technology meet in the machine’s control system. Leading control units such as Fanuc or Siemens make programming and controlling the machine straightforward. The clear color LCD screen and easy connections for data transfer ensure that the machine is quickly ready for use and that program transfers are effortless.
Overall, the DMTG CLS20 is a robust and reliable workhorse that combines high speed and top-class accuracy. It is an excellent choice for machine shops that need a durable and easy-to-use milling machine for daily production, whether it’s for single-part manufacturing or larger series.

Efficient Tool Carousel
In the CLS20 model, there is a fast hydraulic carousel that can accommodate eight or twelve tools at a time. Automatic and extremely precise tool changing takes place in less than half a second, minimizing unproductive times in production and enabling versatile machining operations with a single setup.
Hydraulic Press
The machine is equipped with a hydraulic press with a diameter of either 8 or 10 inches, which ensures a secure and precise clamping of the workpiece. Powerful pressing force allows for heavy cuts safely, and the porous structure of the press allows for efficient rod feeding into continuous production.
Robust and Precise Spindle Cartridge
The machine’s hydraulic spindle cartridge is essential for machining long parts, as it provides the necessary support to prevent vibration. It features a robust MT4 cone and a 130 mm stroke length, which enables optimal support and accurate results in demanding turning operations.
