Ceramics UK 2019 presentation

1. Closing the gap between
lapping and polishing

2. “The importance of advanced materials for
lightweighting, strengthening and improving
performance in sectors such as aerospace,
automotive, electronics and energy cannot be
underestimated and all this will be showcased at this
event.”

3. What does it need to improve perfromance ?
COOPERATION PERSONALIZATION

4. Creating together
something new and better
Microdiamant combines both

5. High performance vs. high quality OR
High performance combined with high qality ?
- equipment
- training
- FAT
- SAT
- documentation
- labour costs related to production time
- energy costs
- consumption of consumables
- waste of material
Continous costs
One time costs
will make the
difference
Optimize the total cost of process (TCP)

15. Core technology portfolio
Polycrystalline
(DP)
Natural Diamond
(NAT)
Nanocluster
(XP)
Monocrystalline
(MSY)
Polycrystalline diamond is
recommended for all lapping,
polishing or brightening
operations
on hard and soft surfaces.
The self-sharpening grain
structure
continuously refines polishing
throughout its cycle,
from removal to polished.
Monocrystalline diamond-
specific
cleavage planes make it
suitable for
operations upstream of your
operations,
specifically for cutting or
lapping.
The sharp, edged forms of
Natural Diamond are ideal for
making the surface of
your diamond tools effective.
The fineness of the Nano-
diamond
is sought for the coating of
functional surfaces or for the
improvement of sliding
properties.
Surface Modified
(SMP)
SMP SmartMicron diamond
powder is made of modified
synthetic diamo. The micro-
structured, rough particle
surface maximizes the
material removal rate due to
the numerous contact points
provided between diamond
particles and the work piece.

28. The importance of the production process
• Narrow particle size distribution
• Regular blocky particle shape
• No oversize
• High purity
• Lot-to-lot consistency
• High resolution measurement equipment
• Guaranteed agglomerate free (GAF)
• Stabilized liquid
• Product quality is manufactured in production process,
involving total quality control from incoming inspection,
in-process inspection and final inspection!

29. Make use of Microdiamants expertise
• Improved TCP
• High production efficency because of
quick change over
• Indipendency of machine type and
brand
• High flatness and excellent surface
finishes
• Reduce wast of material by quick
machine set up
• Modular production system allows
highest flexibility to your needs
