The new circular segment mill
Efficient 3D line-by-line scanning of surfaces and contours

The G-Mold 55 CS four-fluted solid carbide circular segment end mill truly shines in finishing, semi-finishing, and 3D contouring of surfaces and contours on 5-axis machines. As a high-performance solid carbide tool for modern machining, this milling cutter is particularly effective in demanding applications in mold making. Compared to ball-end mills, which are typically used for machining complex geometries, the segmented milling cutter offers up to 10 times larger line increments.

In practice, when finishing large, uniform surfaces and contours on 5-axis machines, users often rely on inefficient ball-end mills—and in doing so, miss out on significant cost-saving opportunities: Compared to ball-end mills, circular segment cutters have a larger contact area with the workpiece. The significantly larger radius allows for a greater path spacing during line-by-line machining, enabling line jumps up to 10 times larger. As a result, depending on the requirements, users can machine up to 80% faster or achieve surface finishes 10 times better.

Smoother operation, better surfaces, 1.5 times the service life

The solid carbide end mill is used for hard and tough materials in ISO groups P, M, S, and H up to 55 HRC. Upon request, Gühring also offers a version of the solid carbide tool with the proven Carbo+ coating for machining aluminum. Its uneven cutting edge pitch ensures exceptionally smooth operation, while the HiPIMS coating provides optimal protection against wear. Compared to competitors, the Gühring tool stands out for its smoother operation, better surface finishes, and 1.5 times the tool life.

The milling cutter’s primary application is the cost-effective machining of complex free-form surfaces, contours, and large surface areas. Thanks to the large radius of the circular-segment tool, the required line spacing can be significantly increased, which considerably reduces machining times.

Gühring provides the entire process

In particular, complex CAM programming often poses a challenge in practice, leading users to continue relying on inefficient ball-end mills despite significant potential for cost savings. Yet modern circular segment end mills offer considerable advantages for machining, finishing, and cost-effective semi-finishing of complex components. As a manufacturer, Gühring brings together all the expertise related to the use of circular segment cutters under one roof and personally supports its customers from process design all the way to the finished workpiece. Upon request, Gühring provides assistance with CAM programming and the selection of the correct process parameters for machining and the use of the appropriate tools. As a result, users benefit from an optimally coordinated process chain, shorter machining times, and optimal results tailored to their specific needs.
