Diamond tools - DIXI Polytool

Diamond tools
summary
1 - Introduction on the different cutting materials called Diamonds
2 - Industries and market niches :
• Jewelry
• Watch industry
• Medical industry
• Optic industry
• Automotive industry, engines
3 - Our new stock of polycrystalline diamond tools
Diamond types and definitions
► PCD : Polycrystalline synthetic diamond
► CVD : Polycrystalline synthetic diamond
► ND :
Monocrystalline natural diamond
► MDC : Monocrystalline synthetic diamond
PCD – POLYCRYSTALLINE SYNTHETIC DIAMOND
! Diamond powder sintered under high pressure
and high temperature on a tungsten carbide basis.
! Diamond grains are linked together with a cobalt
matrix
! The percentage of diamond can vary between 8595% in volume
High pressure
PCD Crystal + metal matrix
CARBIDE
High
temperature
ADVANTAGES OF PCD TOOLS
! “Low cost” diamond tools
! Suitable for the machining of non ferrous materials as aluminium, graphite,
platinum, Green Ceramics, CFRK and GFRK"
! Uniform properties in all directions (Polycrystalline structure)
! Long tool life " reduced stand by time
! High cutting speeds " Increased productivity
! Rather easy to shape and regrind
ND – Monocrystalline natural diamond
! This is the one we find in nature
! These diamonds weren’t selected by the
jewellery, watch or optic industries for reasons of
purity or colour
MDC – MONOCRYSTALLINE SYNTHETIC DIAMOND
! This diamond is artificially recreated
! Generally characterized by its yellow colour
! Purer and more uniform than natural diamond
MDC and PCD Cutting edge
Monocrystalline diamond
or Natural diamond
Polycrystalline diamond
The cutting edge of diamond Monocrystallin is sharper than the one
made in polycrystalline diamond.
ADVANTAGES OF MONOCRYSTALLINE TOOLS
! The main purpose of MDC and ND is to obtain a shining or miror
surface which avoids as far as possible the manual polishing of the
workpiece.

Jewellery Industry
! Ring manufacturing
! Watch making industry
! Chain manufacturing
Jewellery Industry
There are four main manufacturers of machines in the ring industry:
! Benzinger (Germany)
! Aller Spanninga (Germany)
! Posalux (Switzerland)
! OMPAR (Italy)
Benzinger machine - Germany
An inside view into a GOring R2, a state of
the art turning machine for rings made by
Benzinger.
Benzinger machines
Examples of standard tools on Benzinger machines for ring manufacturing.
TL-19 for high finish
turning on outer or
peripheral diameter
FR-TK for turning the corner radius
Posalux Machine - Switzerland
The tools are mounted onto the older machine into
specific tool holders – which are also
manufactured by us.
Various turning tools
Next to the Posalux holder form, which is very popular in other machines, a combination of
the Posalux and standard turning tools are used.
