LEO 120A 2T

LEO 120A 2T
LEO 120A 2T

LEO 120A 2T has been very successful for medium production of diameter up to 60 mm. 

It has two independent heads :

Head A - has expansion spindles and the working stops leaving some 1/100 mm from the final measure ;

Head B - using a specific sleeve, permits the calibration with only one operation on the work piece.  Hence very good for very short cycle time, high tolerances and finishing requirements.

The Expansion Mandrel A can have speed selection for 

220~430 rpm360~730 rpm, 520~1060 rpm, 700~1500 rpm.
The Calibration Mandrel B have only one speed which is pre-selected in accordance with the end user needs for its work pieces.


LEO 120AI 2T

LEO 120AI 2T is able to have constant and independent rotation speed selection for both Mandrel A and B by an Electronic Variation System.

This characteristic makes it very versatile and adaptable for any types of work with different diameter, achieving very high precision for the bore.
