The knife balance is not just measured, not just measured, increased or remove weight. The selection of tools is essential. Short -weight and light tools are easy to balance to good accuracy, and large -scale heavy knives are more difficult and have a tendency to produce great vibration. You can also save time and cutting costs by choosing a handle that has been pre -balanced or prepared to the minimum imbalance.

Further you can reduce the number of balanced numbers through conventional maintenance and careful treatment. Any surface damage to the handle will affect balance and concentric. Why? The effects of the handle defects were amplified when the rotation speed climbed. If your instrument can be ignored at a time of 1000 rpm per minute, the speed increases 100 times when the speed is 100,000 rpm per minute, and the 20,000 -rpm is 400 times per minute.

The excellent concentricity is still more important under the high -speed spindle, because if the tool does not turn around on the center of the main axis, it becomes the primary factor of additional imbalance. But the impact of unbalanced knife handles is also obvious at a lower speed. Small imbalance can cause high force of the main shaft bearing of your machining center, and the continuous large radial force recovers the early failure and expensive machine tool maintenance costs of the bearing.

In addition, remember any adjustment (installation or removing knife components, tightening nuts or any subtle twisting or melting), it takes a certain degree of balance. Even if the measurement of the interference knife is only a few grams and a few millimeters, this unbalanced transformation into a vibration increase, causing the cutting tool to accelerate, deteriorate surface smoothness, and decline in parts of parts (such as the roundness or linear degree of the hole or the linear degree. Lost).
