Suitable for machining on parallel lathes, for grinding machines and mechanical dividing tables for lathes, milling machines and drills.

It is made of tempered steel and adjusted with a light alloy incorporated cylinder, mounted on bearings.

It can be applied on any machine tool with rotary motion and in particular finds its widest use on parallel lathes, revolvers and grinders.
It is used on milling bars and reinforcement.

On this spindle you can mount:

• Single cone pliers BA (DIN 6343).

Hydraulic power supply

Closing the MSTN chuck takes place through pneumatic action.

Secondary turning includes mechanical parts made by secondary machining, useful on one-off parts, small production runs and non-serial production.

Bar turning, on the contrast, works for the mass production of components. Turning from bar takes advantage of bar feeders, on which the bar feeders are collets.

By replacing appropriate adapters, this chuck mounts different collets:

• Simple BA type cone (type DIN 6343)
• BD type double cone
• Multidiameter with BAS type sectors
• BE type traction (also with cup)
• PE-PET expandable type

The MSDTN chucks are made from a block of steel, galvanized and tempered at 60 HRC. Bellegrandi collet chucks are totally adjusted to ensure maximum duration, machining precision and balancing.

This model of chucks are made with flange (AF) adapters and assembled on various types of flanges with attachments ISO-A (DIN 55026), D1 CAMLOCK (DIN 55029).

Hydraulic power supply

The hydraulic spindle power supply enables the opening and closing of the collets and expandable collets on the MITN chuck. Opening and closing of the expandable collets takes place through hydraulic power on the chuck nose of the lathe shaft.

For milling bars, we recommend using BD double cone collets.

MSDTN chucks are made in two versions:

• MSDTN / 1C with 1 impulse chamber – max. pression 30bar
• MSDTN / 2C with 2 impulse chambers – max. pression 20 bar

Secondary turning includes mechanical parts made by secondary machining, useful on one-off parts, small production runs and non-serial production.

Bar turning, on the contrast, works for the mass production of components. Turning from bar takes advantage of bar feeders, on which the bar feeders are collets.

Equipped with high holding force, it can mount a simple BA type cone (DIN 6343 type) and multidiameter with BAS sectors.
The MITN chucks are made from a block of steel, galvanized and tempered at 60 HRC. Bellegrandi collet chucks are totally adjusted to ensure maximum duration, machining precision and balancing.
This type of lathe chuck can work while the motor is operating, allowing part replacement without stopping the machine.
It has high closing force with quick locking of the parts.

The MITN chucks are made with flange attachment (AF) and can be assembled with various types of flange: ISO-A (DIN 55026), D1 CAMLOCK (DIN 55029) attachments.

Hydraulic power supply

The hydraulic spindle power supply enables the opening and closing of the collets and expandable collets on the MITN chuck. It takes place through an hydraulic control center (not provided) with 50-60 microns filter on pump aspiration and 10 microns on the discharge filter.

Bellegrandi collet chucks are totally adjusted to ensure maximum duration, machining precision and balancing.

Opening and closing of the collet in the MSCTNR/AF spindle is done by hydraulic or pneumatic cylinder applied at the rear of the lathe shaft.

The collets that can be installed on this chuck are:

• Simple BA type cone

Using appropriate adapters:

• PE expandable type collets
• PET expandable type collets

The MSCTNR spindle is equipped with the PART EXPULSION GROUP, when the lathe does not have it.

On request, the chuck may be supplied without the PART EXPULSION GROUP.

The MSCTNR collet holding chuck was made to allow the maximum approach to the tool holding turret group.
