 Pacific/Hoe is an acknowledged
leader in the design, manufacture and maintenance of cutting tools for the forest products
industry. Our years of experience in saw manufacturing have led to the development of oa
full range of cutting tools specifically designed for all varieties of cutting conditions
and materials.
Our diamond and CBN wheels have
been carefully engineered to provide top maintenance for all saw tip categories.
Abrasive Types
The following types of abrasives are recommended for wood cutting tool applications
using carbide, stellite or hardened steel cutting faces:
SD - Standard
diamond; manufactured and introduced essentially to replace "D" diamond for
resinoid wheels to grind cemented carbides. SD is a friable, irregular shaped diamond
which provides good retention in resin bonds. Its advantages are that it is free cutting
and easy to use. For example: On low horsepower machines (3/4 HP or less). Grit sizes of
60 or finer.
ASD - Armored
(nickel coated); the coating enables the diamond to be more securely held in the resin
bond and also aids in grinding heat dissipation. Armored diamonds are not as free cutting
as the uncoated type (SD), and armored wheels are more difficult to true and dress. ASD
should be used in wet and dry grinding operations on carbide and carbide/steel where the
steel is 33% or less of the total. Grit sizes 60 to 400.
ASDC - Armored
(copper coated); The benefit over ASD is better heat dissipation, therefore it works best
in dry grinding 100% carbide. ASDC should not be used where steel/braze are contacted.
Grit sizes 60 to 400.
AMD - Armored
(nickel); Blockier shaped diamond that shows advantages where a lot of steel (33% or more)
is contacted along with the carbide. Grit sizes 100 to 400.
CBN - (Cubic
Boron Nitride) is a synthetic crystal that is formed under intense pressure and high heat.
the ctystals are very hard fallong between silicon carbide and diamond on a hardness
scale. Coated with metal, CBN is ideal for grinding stellite and other hardened tool
steels including the "M" and "T" series. Generally, steels with a
surface hardness of Rockwell 50C or above will show excellent results with this abrasive.
CBN withstands very high working temperatures and actually permits the reduction of
temperatures on the workpiece through higher cutting efficiency.
