MSCTN/ISO-A Collet Holders

The MSCTN collet holders began as classic closing equipment for CNC lathes.

They are made from a block of steel, galvanized and tempered at 60 HRC. They are totally adjusted to ensure maximum duration, precision and balancing.

The MSCTN collet holders are made with IS0-A (DIN 55026) and FLANGE attachments (AF).
The opening and closing of the CLAMPS and of the expandable collets on the MSCTN chuck takes place via hydraulic or pneumatic cylinders later applied to the lathe shaft.

The following types of collets may be installed on the MSCTN chuck:

  • the "impact" type with a simple BA cone or double with a BD type cone, multidiameter with BAS type sectors;
  • BE traction type; PE and PET expandable type.

For milling bars, we recommend using BD type double cone collets; for "reinforcement" the use of simple BA cone type collets is recommended.

On request, different types of collets may be assembled using appropriate adapters; these may include "Schaublin (type F and W), "Hardinge", "Crawford" etc…
