Venue: Sukhothai Hotel, Bangkok, thailand

Workshop Cost: US$1,198/Person


The class is intended for MWF producers and distributors, raw material manufacturers and distributors (base oils, additives, etc.), MWF technical service personnel, MWF users (machinists, plant engineers, fluid managers, etc.), equipment suppliers (filtration, water treatment,mist collectors, recycling, etc.) and lab testing equipment suppliers (biological dip slides, conductivity meters, water hardness and other wet chemical test kits, etc.).


This training course is intended for individuals who need an improved understanding of water-dilutable metalworking fluids (MWFs) and why they fail, including fluid formulators, engineers responsible for using, managing or specifying MWFs, tool manufacturers, and those supplying raw materials and additives for MWFs. 


You will learn about fluid problems and their causes, and ways to minimize the risk of failure. We will first review basic information on fluids, water quality, metallurgies, etc., as well as performance factors which are typically evaluated in the laboratory and their correlation with field performance. The last part of the seminar will discuss failure modes and causes and ways to mitigate risk.
