I use Jungner CNC tool and cutter grinders. Jungner makes a grinder that uses a Fanuc 160i mill control. The nice thng with this is they also gave me a c++ source for developing my own windows based macro interface. This give me a windows invironment to run all my specialty programs.
Jungner tool and cutter grinders can run many things other than steptools and endmills. I run staggered tooth mills and punches. Cylindrical grinding and I can mount a vise on the table to form grind rails. I even wrote a program to grind dogbone lathe inserts. A very versital machine using Fanuc controls with open source probe routines. They have a very powerfull AC spindle drive with up to 25HP motors that give full torque down to 1500 rpm.
And the multi-spindle machines are so great. Up to 6 spindles on 1 machine and up to 4 wheels per spindle.
Sandvik in Sweden uses Jungners for producing their HP drills with autoloaders and direct feedback from their inpection system to update for wheel wear. They also use a wheel probing system on the machine to measure wheels after dressing. (BTW Sandvik owns Walters)
