The Role and Importance of Coolant (Metal Processing in Machine Tools)
In machine tools used for processing, the coolant (cutting fluid) used during metal processing is indispensable. By cooling while lubricating the area between the object being processed and the cutting tool, coolant stabilizes processing, improves quality, and greatly contributes to suppressing tool wear and extending its lifespan.
Contact Risks in Coolant Environments and Solutions through Wireless Technology
On the other hand, due to its moisture-containing properties, coolant acts as a risk factor for mechanisms with electrical contacts. For example, in an ATC (Auto Tool Changer), the adhesion or intrusion of coolant can cause short circuits or contact failures, potentially leading to a decrease in equipment reliability.
One effective solution to these issues is wireless technology. By utilizing wireless power supply technology to eliminate the contacts themselves, there is a major advantage in achieving stable operation even in a coolant environment.
Challenges of Waterproof Structures in Conventional Products
However, in our conventional products, although protective methods such as filling resin cases with epoxy have been adopted, it is difficult to completely prevent coolant intrusion over long-term use. This has led to issues such as failures and performance degradation due to water seeping inside.
*The following shows the state of degradation after corrosion.
