Machine Coolant Filtering Successes

The shop is West Coast Saws in Tacoma WA. at 2725 S. Ash St and it is owned by Brian Wallinger. 

 They grind saws and tools within one - one thousandth of an inch and have a computerized video inspection system that examines and records the exact shape and location of each saw tooth.  The grinder rep estimates that they get about twice the service life between rebuilds compared to some other shops because of the excellent maintenance.   They have a dedicated one -micron filter system operating constantly on each machine. 

Refer to our  Filtration Index for more articles on how filtering can inmrove the quality of your work and cut costs.
