DN Solutions’ (formerly Doosan Machine Tools) BVM 5700 is the latest member of its family of vertical machining centers (VMCs). The company says the BVM 5700 is a massive machine, weighing 17,000 lbs with a structure built for cutting performance and accuracy.

With its bridge-type construction and single-direction moving table, the company says it enables customers to 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 is said to shine in production prototype environments.

To optimize precision and productivity in a VMC, the company combined a bridge frame structure — delivering more stiffness, along with better accuracy and speed, and minimized thermal expansion — with a 15,000- rpm, built-in spindle that is powered by a 50-hp motor which outputs 158 ft/lbs of torque. This is said to enable high feed rates when machining aluminum, or heavy cuts in tool or mold steel.

Among the standard features offered is 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.
