技術簡介

完成阻尼間隙調整單元；利用加速規與振動計量測主軸振動量，以建立在相同供油壓力與流量之下，不同阻尼間隙之主軸振動量，轉速30,000rpm時，阻尼油壓力=24.5kgf/cm2，流量=2.05Liter/min之狀況下，無阻尼間隙時之主軸振動量=0.96mm/s，阻尼間隙=0.5mm時之主軸振動量=0.56mm/s。主軸振動量降低至無阻尼主軸振動量百分比=(0.56/0.96)x100％=58.3％

Abstract

The damping gap adjustment unit has been completed. Using accelerometers and vibration meters to measure spindle vibration, spindle vibration levels were established under the same oil pressure and flow rate conditions for different damping gaps. At a spindle speed of 30,000 rpm, with damping oil pressure at 24.5 kgf/cm² and flow rate at 2.05 liters/min, the spindle vibration level without a damping gap was 0.96 mm/s, while the spindle vibration level with a damping gap of 0.5 mm was 0.56 mm/s. The spindle vibration level reduced to a percentage of the undamped spindle vibration level is calculated as: (0.56/0.96) × 100％ = 58.3％.
