Cutting an aluminum sash generates swarf charged by the friction with the blade. Since the surface of an aluminum sash has been anodized, the electric charge of the swarf clinging to the sash does not dissipate. Consequently, the swarf adheres to the sash by the Coulomb force.
- It cannot eliminate static electricity, and increases the charge instead, causing secondary adhesion.
- The effect is insufficient.
Countermeasures with static eliminators (ionizers)
Effective dust removal measures can be taken to reduce complaints about delivered products.
Various costs can be reduced such as the cost for addressing complaints, cost for air gun operation, and cost for installing dust collectors more than are required. It is difficult to calculate the effect of just the static eliminator; however, significant costs can be reduced. Moreover, there is a great benefit in the improved level of trust in the manufacturing quality.
