How diamond
tools are made?
Besides using bond materials,
there are also many other methods to fix the diamond grains onto the
tools. The methods include electroplating, CVD
(Chemical Vapor Deposition), sintering micro-size diamonds in high
temperature and high pressure to form PCD, and combining some layers
of PCDs with a layer of cemented carbide liner to form PDC.
Diamond segments are usually a sintered segment
with diamond grit mixed into a metal powder, which is blended to get
just the right alloy that
will wear according to the use of the finished diamond tool. For
metal-bonded diamond tools, the bond is one of the prime factors when
selecting which tool to use for cutting or grinding a specific material,
depending on how hard, or abrasive, the material is. The
bond used is what dictates the rate at which the metallic powders wear
down and expose new diamond crystals at the surface to maintain what
would be considered a abrasive surface.
Different bond strengths are achieved but the metallic
powders chosen (alloy mix) and how much heat and pressure are applied
to the sintered segment.
Hard bonds are best for soft materials and soft bonds
for hard materials. This may seem counterintuitive,
but it is because particles of the material being cut or polished provide
the wear medium the wears away the bond to expose the diamond grit. Diamond
grit is usually not worn out but simply lost when the bond releases
them. The more particles the more wear. |
Our factories in china are run by old personal friends.
I have stayed in many of there homes. As a guest and I believe I need
to do this to have a good relationship with them and over the years there
has built up a good business friendship.
Miss Zhu she runs a sintering pant to cast diamond tools for CNC machines.
They have layths and other milling machinery to alter and make any metal
object.
Mr chou has a large machinery company he make many items for europe
and america.
Tony makes internation diamond tools (blades) he is bassed very close
to the chineese goverments diamond processing pllant in northern china.
I import them and distribute them here in UK & europe most tools are
free delivery in the EU
