Lubricant– Coolant

Coolants, like water and some water soluble oils, reduce heat

resulting in longer product life and greater cut. In the case of

most o ils o rt allow l ubricants,surface r oughness c an b er educed.

The higher viscosity lubricants produce lower surface roughness,

i.e., grease produces a finer surface finish than oil. In automatic

or semi-automatic operations, it is desirable to use lubricants

or coolants whenever possible.

Product Hardness (Density)

™

wheels are available in a number of densities or hardnesses.

Generally, the softer products, 2, 3, 4, and 5 density, are used

for decorative finishing. They will conform more readily to

surface contours along with generating a more uniform finish.

The harder products, 6, 7, 8, and 9 density, are to be used for

the more difficult blending, cleaning and deburring operations.

Generally, low speeds are desired for generating very uniform

and for use on composite or other soft material applications.

High speeds are recommended when it is desired to remove

or blend surface imperfections. This high speed will result in

faster cut along with finer finishes.
