5-axis universal machining centers from GROB

G350T and G550T – Generation 2

The G350T, G550T and G750T 5­axis universal machining centers provide cus­tomers in the machining industry almost limitless options for milling and turning workpieces from various materials. Three linear and two rotary axes enable five­ sided machining with five-­axis simultaneous interpolation. With a swivel range of 225° on the A‘­- axis and 360° on the B‘-­axis, they provide optimum flexibility in terms of positioning. Their drive concept is based on two symmetrically located ball screws and weight compensation with the G550T/G750T in the Y‘­axis and dynamic,wear­free torque motors in the A’­ and B’-­axis. Further benefits include the optimum position of the operating point (TCP) for extremely high rigidity, the longest Z axis travel for this machine class and the fact that the maximum work piece size can be machined in the workspace with maximum tool length.

G1050 large-scale machining center

Delivers maximum versatility

The G800 has been known as a machine concept for specific customer requirements in the system machine sector since as far back as the GROB in-­house exhibition in 2015. The G1050 now introduces the concept as a standard GROB design for the universal machine market. With its innovative axis concept and ideal pallet size, the G1050 large-­scale machining concept provides customers in the universal machining sector with versatile applications across a wide range of industries. The 4­ or 5­axis modular system makes it ideal for adapting to specific customer requirements.

The palette size of 800 x 800 mm to 1,000 x 1,250 mm is particularly suited to machining large components such as engine parts and rear axle covers for utility vehicles – and even whole axle brack-ets. This means that components can be machined up to an interference diameter of 1,600 mm and a height of 1,500 mm. Steeply inclined chip conveyors in the machine work area are best for chip evacuation – even for dry machining. Precision­ timed
tool­-change alarm for tool weights up to 50 kg ensures excellent chip­-to­-chip times. Due to its generous guide-way distances, the machine delivers amazing rigidity, even with extra-­long tools up to 850 mm.

Plenty of equipment features for great flexibility

Customers can choose from a wide range of GROB motor spindles developed and manufactured in-­house – ensuring optimum process design and the right spindle for their specific requirements. GROB spindles have the shortest run­up times and are easy to access and maintain. They are suited to all common cooling lubricants, giving them universal usability – with excellent mechanical features and extreme durability. GROB large­-scale machining centers give customers the choice of the latest market ­leading CNC control systems, achieving better productivity. Set­up can occur simultaneously to the tool being machined thanks to the dual pallet-­change system. GROB also offers additional software options to suit customer specifications, meaning that the large­-scale machining center can be adapted to specific customer requirements.

The G1050 machine concept provides excellent process reliability, cost efficiency and durability. With the new pivoting milling head on the 5­axis version, the G1050 can switch from horizontal to vertical machining mode in seconds. This makes the G1050 ideal for universal machine manufacturing, the aircraft industry, mold­ making and power engineering in the universal machining sector, too.
