PROPERTIES                               VELCUT ST  53                                                 

This is medium viscosity dark brown oil containing active sulphur, chlorine and oiliness additives. It is suitable for all machining operations on high tensile steel and for less severe operations on stainless and heat resistant alloys. It is also recommended for gear hobbing, thread cutting machines etc

3.    Mist   suppression   would   especially   benefit   older   machining   operation             where   mist collection   equipment   doesnt   exists   and   or   cannot                                           be   effectively   retrofitted.

2.         Reducing   oil   mist   deposition   would   improve   housekeeping   and   fire safety in the plant   and   associated   ventilation equipment.

1.    Reducing the   mist   loading   to   collectors   would   extend   filter   life                                                     and   reduce maintenance costs.

Our VELCUT ST - 53 grades   are   superior   in   all   respects       and   this   technology   could   complement   engineering   control   measures   as:

We have developed cutting oil which has antimist properties and also mist suppressing   character in straight oil grades and proved to be successful in plant study.

machinery and air ventilation work. It may also deposit on pools on plant roofs via   general ventilation duckwork exhausts.  Negative effect of oil mist includes poor air quality on workers breathing zone, housekeeping / safety issues, fire propagation upon   introduction of a spark, and environmental concern if oil on the roof is carried                     down stormwater drains.  Current health and safety regulations giving the maximum   permissible concentration is being scrutinized.

A fluid is   typically   sprayed   onto   cutting   tool   surfaces   during   the   machining    of   metal automotive   components.    The   cutting   fluid   greatly   enhances                  the   machining   process   and   allows   the    mass   production   of   components                 that   meet   engineering   quality   requirements.    Unfortunately,   the   spraying              and   the   high   speed   cutting   action   often   atomize   the   fluid   into    very           small   droplets,   creating   a   persistent, and fog - like mist in the plant. The generation   of even small amounts of mist can become a serious concern because of the nearly   continuous, high production machining activity. Oil mist can remain in the suspended   for many hours and will eventually settle over large areas of   the plant on floors,
