Milling Processes - Geometric Contours and Surfaces with Maximum Efficiency  

Milling processes are highly productive machining processes to produce specific geometric contours on components using geometrically defined cutting edges with rotating tools. In addition to simpler contours, we can also produce highly complex, multi-dimensional geometries on our machining and milling centers, and manufacture them economically and with high precision.

Orthogonal Turning-Milling

Here you can see the technology Orthogonal Turning-Milling

Orthogonal turn-milling is an efficient combination of turning and milling processes to produce unbalanced and eccentric shapes and workpieces at high cutting speeds and metal removal rates. In this process, the rotational axes of the milling cutter and workpiece are perpendicular to each other. The high-speed process allows main times to be reduced and the surface finish of the workpieces to be machined to be shortened.  

Milling-Axis Parallel

Here you can see the technology Milling Axis Parallel

Milling-axis parallel is a dry milling process for efficient and resource-saving machining of centric and eccentric bearing seats, cam forms, key, and counterweight surfaces. In this process, a rotating side milling cutter is set against a rotating workpiece in an axis-parallel manner. Due to the high number of teeth of the tools, an extraordinary metal removal rate is achieved with this process. The technology is used on our specialized horizontal milling centers, which are ideal for this process due to their high stability and very good damping properties. In addition, our in-house technology interface "Cam & Crank Shaft Milling aUI" allows for the creation of machining programs automatically without extensive prior knowledge in NC programming.

Hard Milling

Here you can see the technology Hard Milling

Hard milling is a dry milling process for efficient and resource-saving machining of already hardened workpieces, such as crankshafts from the truck, construction machinery, and agricultural machinery sectors. This can be implemented both in the external cylindrical process and in the orthogonal turn-milling process. With this technology, costly pre- and finish-grinding processes is substituted or reduced to a minimum, resulting in significantly more economical production.

5-Axis Milling

Here you can see the technology 5-Axis Milling

5-axis milling is an extremely complex milling process for producing complicated contours and free-form surfaces by means of interpolating linear and rotary axes. The process requires highly dynamic axis movements and high torques. It can be mapped on our specific 5-axis milling centers as well as on our horizontal turning/milling machining centers.

Deburring

Here you can see the technology Deburring

Deburring involves the removal of mechanical, function-impairing burrs, edges, splinters, and fraying from workpieces and elements using special deburring tools. On our machines, deburring is performed as part of the respective machining process and, depending on the workpiece requirements, can be performed as a forward or backward process, as well as complex machining of 5-axis contours. This saves time-consuming, downstream machining steps, and reliably prevents possible damage or functional impairment in the end product.
