The water used in a waterjet cutting system serves two distinct and different purposes, the cutting process and hydraulics cooling. Poor water quality, as measured by the volume of suspended solids, reduces component life and increases the system’s maintenance requirements, both unnecessary and avoidable costs. By taking some simple steps to implement an optimized filter replacement practice you can maintain the high water quality you have achieved and increase the tool’s performance and operational life. Let’s explore the best practices for making this happen.
