Multifunctional machine tool platform

The MT3 can perform grinding, milling, turning, drilling, and tapping operations on a workpiece in one setup. A vertical cylindrical grinder, supplementing Bourn & Koch’s VBG offerings, the MT3 comes standard with a 42" diameter T-slot worktable and precision grinding spindle with an HSK-50A connection. Machine spindles are interchangeable via the HBK-200 clamping system, allowing spindles to be matched to specific applications.

The machine is expandable from a vertical grinder to a one-and-done machine tool system, incorporating various spindles and tools into an optional cell that are automatically changed via Fanuc R-2000 robot and Bourn & Koch’s Alien Claw end-of-arm tooling, allowing for quick change of most tools and spindles. A spindle rack-and-disk-style tool changer incorporated in the cell manages the various tools and spindles.

The machine is programmed via a combination of Bourn & Koch’s grinding human machine interface (HMI) and Fanuc Manual Guide-i, employing a Fanuc 0i CNC control. A virtual Y-axis allows the machine to perform standard milling functions. The MT3 spindle features a Fanuc Beta-il 160M motor capable of producing 30kW from 2,000rpm to 10,000rpm, providing ample power and range for various grinding, milling, drilling, and tapping applications.
