MCD (Mono-Crystaline Diamond) and CVD (Chemical Vapor Deposition)
are free-cutting, fully synthetic diamond products. Contrary
to natural diamond, MCD and CVD exhibit excellent thermal
conductivity which facilitates heat dissipation and provides
consistent dressing performance and wear characteristics.
Serveral Blades are available to suit a variety of grinding
Dessau MCD Dressing Tools are primarily used for dressing
submicron crystal ceramic abrasives such as 81A, 83A, 85A,
93A, 5SG, etc. (a.k.a. ‘SG’). MCDs also provide
good results when dressing silicon carbides. MCD is not recommended
for dressing aluminum oxide wheels as these abrasives are
not aggressive enough to maintain the free-cutting ability
of MCD. Dessau CVD Dressing Tools are used for dressing conventional
Aluminum Oxide wheels.

Dessau Dressing Blades can be used for straight or profile
dressing, as illustrated below.
Cylindrical profile dressing applications:
MCD inserts can be arranged in parallel or at 45 degrees into the blade dressing blank.
On the basis of crystallography, it may be inferred that "parallel arrangement" is more
wear resistant and more effective when dealing with "hard" wheel bonds.
When dealing with "softer" wheel bonds, the 45 degree arrangement should lead to improved
self-sharpening of the MCD.
Use a blade with no more than three inserts, as more may lead
to profile distortion. Also, use parallel mounted inserts of a minimum cross-section of 0.6mm
such that the edges will hold during profiling.
