In the late 1980's, Hoff Engineering became the first successful American manufacturer of EDM filters. The variety of cutting situations in the field bedeviled the efforts of dozens of other filter companies attempting to enter the market. We engineered reliable pressure vessels and developed wire EDM filter media that provided the right balance of deionized water cleanliness and overall cost effectiveness. Eventually though competitors like Mann + Hummel and Dynamic Filtration also took on the application’s challenges.
Hoff Engineering provides reliable, lower cost, in-tank and quick-couple filters for Mitsubishi, FANUC, Sodick, Makino and Charmilles/Agie wire EDMs. In recent years, lower cost wire EDMs such as AccuteX and Chmer have entered the North American market. We manufacture and stock quick-couple filters for these machines, also.
There are the three inter-related performance parameters in wire EDM filtration.
- Service Life
- Filtration Efficiency
- Unit Price
Twenty-five years of continuous manufacture of wire EDM filters with constant product upgrades has helped Hoff Engineering to get this balance right.
