The compact design with small footprint combined with its high
rigidity, make the CG the perfect machine to work in the most
exigent industrial and production environments. A robust and
reliable machine, the capacity to hold a grinding wheel of up to
760 mm in diameter, make this model the most attractive to
those customers making high production series.
The machine has as well flexibility to adequate more than one
wheel, with the possibility to work with both internal and external
grinding spindles.
In order to fit to the customers requirements, an automatic
loading system can be easily incorporated, in the way of different
technologies like robot, external or integrated gantry and custom
made manipulation systems.
For customers requiring the grinding of bigger parts, the PG
model offers a production solution that can accommodate
parts of up to 2000 mm length and wheels of max. 910 mm in

The LG range has been developed for high precision component
grinding, such as cutting tools, hydraulic components and
automotive parts. The machine’s natural granite base and the
linear motor driven slides provide the high accuracy and thermal
stability required for these high demanding applications. These
specifications also allow the grinding of non-round components.
The use of water cooled electric-spindle makes possible the
combination of conventional and high speed grinding. This
produces a maximum peripheral wheel speed of 140 m/s
and covers the range necessary for grinding with conventional
abrasive (60 m/s) or superabrasives (up to 140 m/s) with
maximum torque.
In addition the machine is versatile and flexible with the direct
driven B axis and the use of multiple wheels.
Requirements of completely automated manufacturing
processes are fullfilled with incorporation of customised
automatic loading systems developed by DANOBAT, e.g.
integrated gantry or robot solutions.

The DANTIP machines are for precision grinding, deburring and
measuring fully assembled variations of jet engine turbine rotor
blade tips.
The DANTIP grinds the blade tips of the rotor while they are
being rotated at high speed, thereby presenting the blades to
the grinding wheel under the appropriate operating conditions.
This feature ensures the highest degree of accuracy that can be
obtained with current technologies.
It has been shown that diametric tolerances can be held to
0.025 mm. This achievement is regarded as very important,
since the clearance between the rotor blade tips and the outer
housing has a critical bearing on the engine’s performance.
