DUOWHEEL
Two grinding wheels in one!
Available for the new WAC QUATTRO & CENTRO machines
DUOWHEEL enables deep and peripheral grinding
With DUOWHEEL, you can have two different grinding wheels
in one tool, which means the following is possible:
CNC shape dressing of ceramic wheels using point
crushing possible
The two wheels do not need to be dressed together
Both wheels can be replaced independently
Refitting option available for new machines
(after technical clarification)
With the additional peripheral grinding wheel you have
the following:
A linear contact between the workpiece and grinding wheel
Lower grinding forces
Better cutting quality
Additional geometry options
Two grinding wheels in one
Pre-grinding and finishing grinding are possible in
one clamping operation

Grain size (FEPA)
The grain size of the diamond- and CBN grinding grain used is adapted to the task
as well as to the required surface finish quality.
Grain type / cutting material
Depending on the task at hand, we use different grain types made of diamond and CBN.
The two types differ in terms of their characteristic properties (splintery, block-shaped, free-cutting, etc.).
diamond
CBN
Bond
We use the following bonding systems for grinding the tool inserts:
Synthetic resin bonding, multi-layer
Metal bonding, multi-layer
Ceramic bonding, multi-layer
Concentration
For multi-layer bonds (R,M,V), a grinding agent concentration is selected that permits
the longest possible tool lifespan and results in the required surface finish quality.
