TOOLING SYSTEMS INTRODUCTION BALANCSN Balanceable Collet Chucks Balancing Elements 4. Run a test with the assembled collet chuck on the balancing machine. Read the results for the unbalance angle orientation and the gr x mm unbalance value. 5. Loosen the 3 locking screws on the angle reference ring and align the two balancing rings with the measured unbalance value. Rotate both balancing rings to the unbalance angle on the angle reference ring (or to the laser mark on balancing machines with a laser indicator). Tighten the locking screws. 6. Run a second test with the assembled collet chuck and read the results. Note: The reading should be within tolerance or very close. If the necessary balance on the machine has been achieved, the tool is ready for operation. If the balance is out of tolerance, one of the following procedures should be performed: Peak Point u = M 9,545.G N U = Residual unbalance (g x mm) M = Tool mass (kg) G = Balance grade N = RPM U < 1 g x mm Value examples M = 1 kg G = G2.5 N = 15,000 RPM U = 1kg 9,545.2.5 15,000 =1.59 g x mm Please note: The values on the balancing rings are indicated in metric values. Therefore all guidance examples for balancing are in the metric system. ISCAR can commit only on unbalance values larger than 1grxmm BALANCIN Collet Chuck & Top Nut Operating Instructions The following procedure should be adjusted according to the specific type of balancing machine being used. Loosen the 3 locking screws on the angle reference ring (blue). Align the two balancing rings (gold-colored) to the ‘0' position on the angle reference ring. After the rings are all aligned, tighten the 3 locking screws. Insert the collet chuck into the spindle and tighten it using the pull stud. Insert the cutting tool into the collet chuck, adjust to desired projection and clamp it. Enter the required parameters on the balancing machine: balancing grade (G..), RPM, etc. First Option IF unbalance is within 0-3 gr x mm and within ± 20° from original angle, THEN increase the original value of gr x mm on the balancing rings according to the reading on the machine, without changing the original angle position. Second Option IF unbalance is within 0-3 gr x mm at an angle of approximately 180° from original angle, THEN decrease the original value of gr x mm on the balancing rings according to the reading on the machine without changing the original angle position. Third Option IF unbalance is less than 1 gr x mm at an angle between 20° to 90° from the original angle, THEN rotate both balancing rings approximately 5° towards the indicated direction. Fourth Option On some balancing machines it is possible to adjust the unbalance by rotating the peak point marked on the balancing rings to the required angular position. 836 ISCAR
