Extrusion International 1-2025

37 Extrusion International 1/2025 simple rotation to the other shaft end, the spindle can use a second tool. The closed design with a protective cabin prevents chips from leaving the cabin. Thanks to two manu- ally opening doors, the operator has easy access to the workpiece. The operator also bene ts from simple han - dling via the integrated, swiveling control panel with a NUM controller. Dynamics and Agility swissplast was very satis ed with the rotary table sys - tem and needed machines for its continuous growth, HG GRIMME SysTech was able to deliver two more CNC machining centers in 2020. Both milling machines are designed for signi cantly larger and heavier parts. The G-S-E(24-13)/B in gantry design is conceived for work- pieces with external dimensions up to 2,400 x 1,300 x 600 mm (X/Y/Z), while the portal machine P-S-F(25-13) offers 100 mm more space in the X-axis with otherwise identical cubic dimensions. Their tables can be loaded with up to 800 kg. “We quickly realized,” says Ninyan Bieri, “that HG GRIMME SysTech is a reliable partner, very easy to reach, and quick to react. Moreover, like us, they are a family-owned company and correspondingly dynamic.” Martin Sombrowski, Sales Manager Europe at the Ba- varian company, agrees and cites an example: “Many appreciate that our service always responds very quickly to inquiries. We are also proud that many of our ma- chining centers are ready for operation and producing chips just two days after delivery.” COO Bieri also places great value on the agility and exibility of his group of companies: “We act and grow quickly. We live our motto ‘swissplast – easy to deal with.’ If necessary, we can also handle projects with thir- ty new tools in one go and in an incomparable time.” Highly Productive CNC Machining Centers He cites the focus on thermoforming, the young and very exible team, and the modern machinery as factors for success. Moreover, the thermoforming systems at the locations are usually available in dupli- cate, and the machining centers are highly productive. “Therefore, we can handle very urgent orders at two locations simultaneously if needed. Our employees go along with this and work wherever they are needed,” Bieri raves. Since 2020, the newly added CNC machining centers have also contributed to the rapid machining of parts. Like all systems from HG GRIMME SysTech, they score points with a particularly solid design that absorbs vi- brations to the greatest possible extent. The result is im- pressive, nds Sales Manager Sombrowski: “With this, we achieve high precision in milling and drilling with positioning accuracies of ± 0.045 mm. This leads to ex- cellent surface qualities.” In addition, the machines feature powerful high-fre- quency milling spindles with up to 15 kW of power in continuous operation (S6). These deliver speeds of up to 36,000 rpm on the portal machine. Dynamic accelera- tions and cutting speeds also ensure highly productive high-speed machining. Prepared for the Future The machining centers are also prepared for further growth at swissplast: Although they are currently in use as single-table machines in Gotha, there is the op- tion for the future to divide the working area and then produce even more productively in tandem operation. The machines can also be easily adapted to changing requirements. In addition to a wide range of accessories, numer- ous options are available for individual con guration. These include, among others, magazines for additional tools, measuring probes for breakage and length con- trol, workpiece measuring systems, special packages for dust-free CFRP machining, and an alternative Siemens control system. Ninyan Bieri’s conclusion on the machining centers from HG GRIMME SysTech: “We are satis ed with the quality of the machines and also with the price-perfor- mance ratio.” The Author F.
