FG-7 / -15

The FG series is a stand-alone flute grinding solution.
Oil cooled direct drive Fanuc servo spindle motor with programmable speed from 0-12/15.000 RPM’s. The nominal power is 7kW with 10kW peak performance for model FG-7 and 15kW with 19kW peak performance for model FG-15. For tools with diameters over 20mm we will soon offer our FG-35 with 35kW motor, which is currently under development.

The machine is equipped with a 6 axis Fanuc control with option for (on the smaller FG-7), a 7th axis for table tilt, where the tap chamfer can be ground by using a straight 1A1 wheel.  Menu driven, user friendly software with clear screen icons and instructions makes operator trai-ning easy. The flute profile can be entered by DXF file or through screen menus with 2D flute simulation software. 3D simulation is available for complex flute geometry, based on a standard SolidWorks software platform, with menu driven parametric data input.

The machine will grind straight, right and left hand helix, with grinding wheels from 50 to 220mm diameter. With 2 wheels mounted on the flange, gun point can be ground with discrete profiles for flute and spiral point.  The built in 2 axis diamond roll dresser has full flexibility to dress multiple different wheel profiles – and dressing can be com-pleted during the automatic robot loading cycle, improving greatly on floor to floor cycle time. The Fanuc robot with dual head gripper, completes the loading cycle in less than 6 seconds. Standard round collets can be used due to the pre-locating devise securing perfect alignment between square and flute. 3D printed coolant spouts simplify the set-up greatly and directs the oil accurately saving pump capacity and energy. To complete the array of features for tap flute grinding, the FG machines all feature a program-mable sliding tailstock with the option to grind with center or bushing support.
