The FGseries 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 training 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 wheelprofiles - and dressing can be completed 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 programmable sliding tailstock with the option to grind with center or bushing support.
