EVOLUTION LINE

The Evolution line of Parlec by Gerardi angle head has been designed from a

technical base derived from 40 years experience of solving thousands of pro-

duction problems, finding optimum solutions and always guaranteeing the
highest product quality. Over 30 standard angle head types are now offered,

designed, built and distributed in more than 50 countries the worldwide by

Gerardi S.p.A., and available with a range of options to complete their applica-
tion and performance potentials.

Technical features
1. Minimum thermal expansion and high corrosion resistant treated steel body

2. Modularity: main shaft with interchangeable Drive Taper (Double contact) allows an EVOLUTION
angle head to be used on other machining centers with different spindle types and sizes. It is
also possible to exchange the anti-rotation (arrester) sub-assembly and the input drive taper
with no effect on rigidity or accuracy.

3. All spindles are supported by pairs of preloaded angular contact ball bearings with ABEC
7/9 precision and long life lubrication.

4. Made with Gleason ground spiral bevel gears for optimization in torque availability.

5. More than 42 angle head types available.
6 Among the new range of angle head types the Slim series has reduced weights and over nd
overall dimensions with a minimum diameter of 35 mm.

7. Up to 150 psi (10 bar) coolant through the pin (Incl.) in the standard heads. Options include
feeding coolantat 150 psi (10 bar) though the cutter spindle or at up to 1000 psi (70 bar) through
the machine.

8. Designed for superior heat dissipation and for sustained periods of high speed operations.

9. 100% compatibility with heads installed during the last 40 years
(same anti-rotation/arrester pin and stop block dimensions).

10. Parlec by Gerardi Evolution angle heads have been designed and are manufactured in Italy. They
are covered by 1 year warranty.
