Grob Systems Unveils G550T Mill-Turn Machining Center for Advanced Five-Axis Power Skiving!

At Eastec 2025, Grob Systems showcased its G550T five-axis mill-turn machining center, an advanced piece of technology engineered for precision machining of complex parts, including those used in five-axis power skiving applications. The G550T is a game-changing solution, offering maximum stability and optimum maintainability for high-performance operations across various industries, particularly in power transmission components.

The G550T is equipped with an impressive range of features that cater to challenging tasks, including power skiving, which requires complex, high-precision cutting. The large swivel range of its axes—230 degrees in the A-axis and 360 degrees in the B-axis—ensures flexibility in positioning, allowing it to handle a wide array of machining tasks. Additionally, the machine’s horizontal spindle position enables a long Z-travel path and promotes optimum chip fall, reducing the likelihood of material buildup during operations.

One of the machine’s standout features is its axis arrangement, which minimizes the distance between the guides and the machining point (TCP), resulting in superior stability during part production. This layout not only enhances cutting precision but also improves overall machining accuracy, particularly in multi-axis applications.

Another major advantage of the G550T is its tunnel concept that enables large components to be swiveled and machined within the work area, even when using extremely long tools. This design eliminates potential collision issues that typically arise when working with large workpieces or extended tools, ensuring uninterrupted machining without compromising part integrity.

The three linear axes combined with the two rotary axes enable true five-sided machining and allow for five-axis simultaneous interpolation, providing flexibility to perform complex cuts in a single setup. These capabilities are especially beneficial for tasks like power skiving, which often requires a highly intricate cutting process.

Moreover, the G550T integrates Grob Traori turning, a unique technology that enhances cutting control, ensuring precise, high-quality cuts for a range of materials. This feature allows for stable turning and is particularly effective in producing high-precision components for industries such as aerospace, automotive, and tool manufacturing.

The G550T’s combination of five-axis machining flexibility, stable cutting dynamics, and the ability to handle large and intricate components makes it a leading choice for industries requiring precision power skiving and complex part production. Its efficient design ensures that manufacturers can improve their throughput without sacrificing accuracy or quality—essential for industries where both precision and efficiency are paramount.

As Grob Systems continues to push the boundaries of technology, the G550T mill-turn machining center exemplifies the company’s commitment to providing innovative solutions that drive productivity, performance, and reliability in the machining world. This machine will undoubtedly play a crucial role in enhancing production capabilities for manufacturers looking to stay at the cutting edge of advanced machining technologies.
