Cutting Swarf Adhering to Tools
In the process of cutting or polishing resin parts, swarf generated is charged with static electricity due to the friction with the tool. The swarf adheres to the tool, and if processing is continued, it may scratch or soil the worked surface or cause edge chipping.
Conventional countermeasures
Air blow
- Cannot eliminate static electricity, actually increases the charge.
- Cannot remove foreign particles completely.
Countermeasures with static eliminators (ionizers)
Ionized pulsed air blows off foreign particles.
It reduces disposal costs and saves takt time.
Improvements and Effects
Words from the worksite
Reduced disposal cost due to foreign particles and reduced work time
Disposal cost due to foreign particles: $500/month x 12 months = $6,000/year
Reduced work time: 60 seconds before countermeasures, 45 seconds after countermeasures
In addition, there are other invisible benefits of improved levels of trust.
