MAD/T  Semi-automatic self-centering power chuck. Draw rod clamping and manual indexing

FEATURES:

Chucks series MAD are self-centering.

In version MADT jaws clamping is automatic trough a draw rod and a rear cylinder, in version MADV jaws clamping is manual thanks to an operating key.

Chucks MADT and MADV have booth manual indexing system.

In MADT and MADV power chucks manufacture and design we have applied the experience and the technology matured in particular in indexing power chuck design.

The originality of these indexing self-centering power chucks comes to the constant improvements tecnomors done since the early 1960’s after the first chuck prototype realisation.

The main MAD power chucks features are:

1.1 - made in special high resistance hardened and cementing 60HRC steel UNI18NiCrMo5, to maintain a high degree of precision, reliability and quality.

1.2 - jaws slides execution with gib allows good sliding surface finish with possibility to recover clearances consequent to wear.

1.3 - indexing movement simple and reliable: a conical shutter guarantees the mechanical indexing. Indexing precision ±1’30” .

1.4 - shaft guide system with two lines of big filled cylindrical pre-loaded radial rollers and with an axially strong ball bearing.

1.5 - seals against contamination by coolant, chips and dust.

1.6 - constant and long lasting precision.

1.7 - easy installation to the machine.

1.8 - standard with 4 indexing 90° + 1 indexing 45°.

On request special indexing positions available (8x45°, 6x60°).

1.9 - MADT specifications :

      - self-centering clamping.

      - big clamping capacity.

      - versions with long jaw for workpieces that need a big radius of revolution.

      - quick and easy installation to the machine, it is request only the connection to the hydraulic cylinder on the lathe.

1.10 - MADT benefits:

      - manufacturing of different pieces and also of small series.

      - workpieces with big radius of revolution and flanges with big diameter.

      - could be apply in the same machine with a conventional 3 jaws power chuck thanks to the quick retooling increasing unit flexibility and productivity.

      - the indexing device allowing a quick change between the multiple working axes.

      - good tools accessibility thanks to the chuck shape.

2.1 - a special tecnomors device with titled plane transmits the clamping force to the jaws.

2.2 - Chuck is supplied without driving cylinder. See the specific chapter to check  cylinder and chuck size.
