This model is an updated version of our 5-BVK which was introduced in the early 1990's. The head now has a state of the art Yaskawa vector drive.  It features a rigid C-frame with a larger quill than our turret style mills, and gives a longer quill stroke. The table / saddle construction is like a machining center in that the X axis ballscrew is mounted in the saddle. The saddle is 38" long, giving excellent support to the 43" long table. Furthermore, this style allows a much more rigid mounting of the Y axis ballscrew nut.  This reduces table / saddle chatter significantly compared to a Bridgeport style table / saddle. The trade off is that handwheels cannot be mounted.  For that reasone we strongly recommend the optional MPG ( often called an electronic handwheel) This can be seen hanging on the right hand side of the operator's console.  It gives electronic manual feeds on each axis down to 1/10 thou.

We do have a version of this machine, called a 5-BGLS which has a standard Bridgeport style table / saddle and has handwheels on X and Y for those situations where handwheels are needed.

The vector drive head gives full programmed spindle speed control to the CNC which allows tapping with a standard floating tapping head.

We can fit this head on this machine with a power drawbar that will enable use of standard CNC Cat-V-40 or BT-40 tooling such as that offered by Command
