Expanding sleeve mandrel KEM-AS-A6

for turning applicationsfor internal turningmodular

Overview
The KEM-AS-A6 is an expanding ID mandrel designed for accurate internal workpiece gripping on lathes. It features a pull-back design for dual-contact rigidity and a common flange for modular interchangeability.

Key features

• Pull-back dual-contact design draws the workpiece against a part locator for increased rigidity.
• Modular flange configuration ensures interchangeability with compatible back bodies.
• Specify standard or flush sleeves at time of order.

• F: 14.5 mm
• G: 22.1 mm (G flushed: 25.4 mm)

Technical parameters

• Spindle mount: A2-6
• Mandrel gripping range: 12.4 mm - 22.4 mm
• Sleeve gripping range: 0.5 mm
• Maximum pull force: 7 kN
• Maximum gripping force: 12.5 kN
• Maximum drawnut threaded diameter: M75 x 2

How to order

• 1. Choose the mandrel model based on the diameter(s) you plan to grip — mandrels are identified by gripping range.
• 2. Select the part number matching your lathe spindle mount — each ID system includes a drawtube connector that can be customised to your drawtube.
• 3. Order the appropriate sleeve(s) and part locators separately; specify standard or flush sleeves when ordering.

Included and design notes

• Each mandrel includes an expanding rod, expanding rod adapter and mounting hardware.
• All expanding sleeves are bonded to seal against coolant and chip penetration.
• Double-angle design provides parallel sleeve expansion for full-length workpiece contact and positive release.
• Sleeves collapse 0.1 mm below nominal ground diameter to ease part loading/unloading.
