The
best-all-round coolant for carbide tools is
Soluble
oil in plant
Kerosene
Turpentine
oil
Compressed
air
Soluble
oil in plant
Since
carbide have high value of hot hardness thus, for cooling tools like carbide
soluble oil inplant coolant is used.Soluble oil have high cooling capabilities
and good lubrication becauseof blending of oil and water.
Hence, the correct option is (A)
&Key Points:-
Soluble
oil provide a protective oil film on moving components of machine tools and
resistemulsificationof greases and slide way oils.
