Maximising productivity with Grob 5-axis machining centres
In the machining industry, the ability to produce complex parts with high accuracy in the shortest possible time is a decisive factor for success. 5-axis machining has established itself as a fundamental technology for achieving these goals.
Unlike traditional 3-axis machining, this technique allows the cutting tool to move along three linear axes (X, Y, Z) and two additional rotary axes, making it possible to approach a part from multiple angles in a single set-up. The result is a significant reduction in set-up times, greater accuracy and the ability to produce geometries that were previously out of reach.
Ferrotall offers the industry a complete range of 5-axis machining centres from the prestigious GROB brand, specifically designed to boost workshop productivity. These machines are a high-performance solution for companies looking to optimise their processes and expand their manufacturing capabilities, enabling more agile and efficient production.
GROB machining centres offer direct benefits in a workshop's day-to-day operations. Their design is geared towards high productivity and optimised cycles, which translates into greater profitability. They provide great operational flexibility and excellent visibility of the working area, improving process control.
Despite their large capacity, they have a compact design that optimises floor space and a sustainable approach to construction and operation. In addition, their design ensures optimised access to the machining area, making the operator's work easier.
Unique technology that drives productivity
The superiority of GROB machining centres is based on a unique machine concept, with engineering innovations that translate directly into better performance.
- Maximum stability: the architecture of the three linear axes is configured to minimise the distance between the guideways and the tool tip. This short lever gives the system outstanding stability, allowing machining operations at higher speeds with first-class dimensional accuracy and surface finish.
- Tunnel concept: this feature, patented by GROB, makes it possible to machine 100% of the working area for any part size, even when using very long tools. The design ensures that no travel is lost and that there is no interference or risk of collision, maximising the machine's real capacity.
- Wide swivel range: the combination of three linear axes and two rotary axes allows not only complete 5-sided machining but also simultaneous 5-axis interpolation. With an extraordinary swivel range of 230 degrees in the A axis and 360 degrees in the B axis, these machines offer superior versatility for tackling the most complex geometries with unrivalled efficiency.
Featured models in the GROB range
The GROB range offers solutions for different production needs. Two clear examples are the G150 and the G750.
The Grob G150 is a compact machining centre ideal for parts that require maximum accuracy. Its technical specifications include X/Y/Z travels of 450/670/665 mm and rapid traverses of 50/40/60 m/min. With an interference diameter of 580 mm, a chip-to-chip tool change time of just 2.6 seconds and a positioning accuracy of 0.006 mm, this model is a high-capacity solution for producing technically demanding parts.
For larger parts, the Grob G750 demonstrates the range's capability for large-volume work. It offers X/Y/Z travels of 1,000/1,100/1,170 mm and rapid traverses of 60/50/75 m/min. Its interference diameter reaches 1,280 mm and, like its smaller sibling, it maintains a positioning accuracy of 0.006 mm, with a tool change time of 3.4 seconds. These specifications make it ideal for large, heavy components where accuracy cannot be compromised.
Applications in highly demanding industries
The versatility and high performance of GROB machining centres make them suitable for the most demanding industrial sectors, including aerospace, automotive, medical, renewable energy, mould and die, and engineering and contract manufacturing services in general.
