Retero GmbH > Home > Services > 3D Milling with CNC / NC Milling

In 3D milling, workpieces can be machined in all three spatial directions X, Y and Z. Due to the dynamic movement of the three axes, both concave and convex contours can be milled. Two CNC vertical machining centers, an NC milling machine, conventional lathes, a surface grinding machine for fast and efficient production of fixtures and milled parts, as well as a great deal of know-how optimally complement our range of services.


CNC-controlled 3D milling machines get their commands from a computer programmed with all the relevant data. In this way, extremely precisely manufactured parts can be produced from various materials.

3D means three-dimensional, we machine the width, the height, and depth of a workpiece. Due to the high-precision computer control, we can also mill out reliefs. For example, if the computer of a 3D milling machine is fed with the exact data of a mountain profile, the milling machine can produce the complete surface structure of the mountain in miniature.


The smaller the part, the more precise the work. The smallish a part of a mechanical system is – e. g. components of a wristwatch – the more drastic is the effect of even the slightest deviations from the specified masses. In the construction of a house, deviations of a few millimeters do not have much effect on the quality of the building, but when it comes to precision engineering, even deviations of a few thousandths of a millimeter can have negative consequences.


Only precisely manufactured parts guarantee the best possible quality of complex mechanical workpieces. All individual parts must fit together perfectly; any deviation from the standard generates errors in micromachining. 3D milling in micromachining ensures the highest possible precision and thus provide the basis for best quality.
