ECONOMICAL SOLUTION FOR HIGH PRODUCTIVITY FLUTE GRINDING

Precision Flute Grinding

ITM’s UFGG is a high production flute grinding machine with a heavy welded and stress-relieved base, grinding spiral and straight flute, fast helix, or gun-nose in one clamping. The workhead (A axis), rotary table (U axis), cross slide (X axis),
longitudinal slide (Y axis) and vertical supported column (Z axis) are CNC controlled. The X, Y and Z axes have an incremental movement of 0.00004in with a rapid traverse rate up to 98.4in/min. The resolution of the A, and U axes is 0.001°. The inprocess dresser uses 2 CNC axes, vertical slide (V axis) and horizontal slide (W axis).

With 7 CNC controlled axes plus a 2 axes CNC loader or 6 axes Fanuc™ robot loader, setup time is usually 25 minutes or less, making this machine economical for both large and small production runs. Due to the rigidity of the machine, along with programming capability, standard resinoid, plated CBN, dress-able CBN or diamond coated wheels can be utilized. When the correct grinding wheels are used, the machine can be operated with wheel speed up to 262ft/s.

HOW IT WORKS

The tool blanks are loaded either manually or with the optional automatic loader and held in collet and tailstock center for grinding. The U axis then rotates to the desired helix angle and the grinding cycle begins. The grinding process uses X, Y and Z axes interpolation while rotating the A axis workhead to generate desired spiral fluting geometry. For straight flutes, the U axis remains in the “zero” position and the A axis is used for indexing. When the fluting is completed, the dressing cycle begins, re-truing the wheels for the next part if necessary. The frequency of the dressing cycle can be selected. Dressing is only possible for standard and CBN wheels. This machine can be set-up to grind straight flutes, straight flutes and gunnose, or spiral flutes in one clamping. Using the Fanuc™ robot loader, it is possible to run the machine unattended as long as good grinding technology is used, allowing for long periods of production without operator involvement.
