Bridge-Type VMC is Built for Cutting Performance, Accuracy

DN Solutions (formerly Doosan Machine Tools) introduces and demonstrates the BVM 5700, the latest member of its family of vertical machining centers (VMCs), at IMTS 2022 booth ##338900. The BVM 5700 is a massive machine, the company says, weighing 17,000 lbs with a structure built for cutting performance and accuracy. With its bridge-type construction, and single-direction moving table, DN Solutions notes that customers can handle heavier parts and cut with increased rigidity. Its design and sheer mass also reportedly provide excellent dampening characteristics that offer high-quality 3D machining surface finishes where precision surface finish is demanded. The BVM 5700 shines in production prototype environments.

To optimize precision and productivity in a VMC, DN Solutions combined a bridge frame structure — delivering more stiffness, along with better accuracy and speed, and minimized thermal expansion — with a 15,000 r/min built-in spindle that is powered by a 50 hp motor that outputs 158 ft/lbs of torque, according to Jim Shiner, vice president of sales and marketing at DN Solutions America. This enables high feed rates when machining aluminum, or heavy cuts in tool or mold steel.

The company’s goal for the BVM 5700 was to give end-users everything they needed right out of the box. Among the standard features offered are AICC II with Smooth Surface Package, which is said to benefit anyone doing high-speed machining or contouring applications. There’s also a Machine Condition Selection Function with a spectrum of accuracy or speed for dialing in the ideal setup. The Smart Thermal Control actively compensates for temperature fluctuations through a series of sensors placed throughout the machine. Also standard is a Fanuc 0i Plus controller with a 15" touchscreen and iHMI.
