Diamond Segments of Wall Saw
About diamond
segments
Diamond segment are
the functional parts of a metal-bonded diamond tool. The
metal-bonded diamond tool can be a metal-bonded diamond blade, a
diamond grinding cup wheel, a diamond core drill bit, a diamond
gang saw blade, etc. The diamonds of a metal-bonded diamond tool
are all in the tool's diamond segments to play their role of
cutting or grinding.
Structure
Diamond segments consist of small-size diamonds and metal bond
materials. The metal bond materials may include the powders of
Cu, Sn, Fe, Ag, Co, Ni, WC, Mo, graphite, etc. The diamonds are
mixed with the bond materials, and the mixture is loaded into
molds. After hot pressing or cold pressing, sintering, and arc
grinding, diamond segments are formed. The metal bond has two
basic functions: One is bonding the diamonds to the body of the
tool; the other is wearing along with the diamonds' wearing to
let the new sharp diamonds be exposed properly.
Generally, a diamond segment has a working layer and a
transition layer. The working layer contains diamond grains for
cutting or grinding, while the transition layer has no diamonds.
It just consists of bond materials, and is used to connect the
working layer to the body of the diamond tool. The transition
layer is necessary for diamond segments used on laser-welded
diamond tools. The compositions of the two layers should not be
very different. Otherwise, the junction of them will tend to
break because of the uneven heat and forces received by the two
layers when the diamond tool is in use.
The diamond segments used on large diamond circular saw blades
or diamond gang saws for cutting stones can be layered and have
some non-working layers separating the working layers. The
working layers contain the common materials of diamond segments,
including diamonds and metal bonding materials, while the
non-working layers are usually made of metal powders. This
design can increase the sharpness of the diamond segment, and
lower its production cost.
Forms
Diamond segments may come in various forms on diamond tools.
For a diamond blade, diamond segments are just the "teeth" of
the blade. The form of the segments is an important factor which
influences the performance of the blade, for example, the
blade's cutting efficiency and the ratio of the diamonds'
non-normal failure.
The form of diamond blades' diamond segments may be convex,
layered sandwich concave, L-shaped, step-shaped, segmented,
side-slotted, etc. There are mainly two purposes to make these
forms: one is to increase the blade's capabilities of containing
and discharging sawdust, and improve the cooling and lubricating
conditions. The other is to reduce the friction between the
segments and the material being cut as well as the sawdust,
improve the blade's cutting capability, and thus save energy and
improve the blade's performance.
The diamond segments of diamond grinding cup wheels also have
many different forms to fit different grinding applications.
Use
The features of the diamond segments on a diamond tool should
match the nature of the material to be cut. If the material is
hard, the bond of the diamond segments should be softer. Because
diamonds are apt to become blunt when cutting hard material. The
softer bond can be worn down with the blunt diamonds faster, and
then make new diamonds beneath be more easily exposed to
participate in cutting. If the material is relatively softer,
the bond should be harder. For in this case diamonds can last
longer. The harder bond wears slower, so that it can hold the
diamonds also longer. This can make better use of the diamonds
and prolong the diamond tool's service life.
The grit (size), hardness and concentration of the diamonds in
the diamond segments should also be considered. For example,
when the material to be cut is soft, the diamonds' size can be
big, hardness can be medium, and concentration should be a
little bit higher. This combination can get good cutting
efficiency, and at the same time prolong the blade's life. When
the material is hard, the diamonds' size should be small,
hardness should be high, and concentration can be a little bit
lower.
