These machines are characterized by huge working areas, extremely high dynamics and milling capacity, as well excellent surface finishing. Customers value Zimmermann as a partner with high system solution competence. In addition to the actual milling machines, software, smart milling technology, additional tools, disposal technology and individually adapted project management complete the portfolio.

The moving masses are extremely low so that especially large workpieces can be machined. Five-sided, five axes machining enables even highly complex shapes to be milled from the material in a short time. Light alloys, plastics and composite materials can be machined as well as steel and cast iron. The machine design reduces vibration to a minimum, meaning that maximum dimensional accuracy and surface quality as well as maximum milling capacities can be achieved. 

Moreover, a modular design had to be possible. Our HPLS (High Performance Linear System) rack and pinion system convinced the developer team in all respects:  Use of our RP high-performance planetary gearbox with its high torsional and tilting rigidity enables very high system rigidity over the complete axis length. This enables very high speeds, acceleration and accuracy to be achieved on the X, Y and Z linear axes during precision HSC (High Speed Cutting) machining. Our high-performance RP050S planetary gearbox in the Z-axis is able to absorb the entire forces. Consequently, hydraulic weight compensation can be dispensed with. This reduces the number of components and the assembly and control requirements.

Through the use of racks, very large axis lengths can be achieved – this would not be possible using ball screws. The machine enables working areas of up to 40,000 millimeters in the X-axis, 6,000 millimeters in the Y-axis and 3,000 millimeters in the Z-axis. Movement guidance with rack and pinion drive is smooth and powerful in all linear axes. Surface finish and precision meet the highest standards. The volumetric precision, for example, can reach 55 µ. Moreover, our system operates significantly more energy efficiently than alternative solutions with linear motors.
