Pre-Coat Filter

Pre-coat Filter
The Pre-Coat Filter is a high-accuracy coolant filtration system for high-accuracy machining processes.


A fine filtration film is formed on the front surface of the specially-shaped filtration material using a filtration additive, allowing the machine to perform high-precision coolant filtration.
Additive that has been dirtied through filtration is detached from the filtration material by air using a backwash process, and is discharged after desiccation.
This process maintains reliable filtration functionality at all times.



  • Metal precision grinding (Water-based and oil-based)
  • Wire-electrical discharge oil (Shaping, wire-cutting)
  • Non-magnetism coolant (Aluminum, carbon, carbide)
  • Barrel polishing coolant and other
