Power Shrink Chuck with Safe-Lock™
ASME B5.50 · CAT50

Shrink fit chuck suitable to all inductive shrink fit units.

The Power Shrink Chuck is the shrink fit chuck for highest machining capacity in high-speed manufacturing. The optimized design combines high rigidity with dampening vibrations, therefore giving more protection to machines, spindles and tools.

Increased machining capacity due to higher spindle speeds, higher feed rates and larger cutting depths
Shorter processing times
Quieter running, therefore better surface quality and protection of tools, spindles and machines
Higher machining accuracy
Coolant supply form ADB
With threaded holes in order to balance with balancing screws
Cool Jet coolant bores that can be sealed included
Cooling with Cool Flash for an extra charge
Safe-Lock™ pullout protection

The oversize and ZG200 versions with slim tips are especially versatile to use.

High rigidity
Slim at the tip
Dampen vibrations
Higher clamping forces
Equally suited to high-speed manufacturing and heavy milling
Universal usage, saves space in tool magazine

Technical data subjects to change without prior notice.

The most important features:

1. High runout accuracy (< 3 μm)
2. Low tendency towards vibrations by optimised outer geometry
3. Slim design at the top
4. Very rigid shank
5. Standard with Cool Jet (can be re-sealed)
6. Dirt groove in the clamping bore for safe clamping force
7. Safe-Lock™ (optional)

Safe-Lock™ pull out protection

Highly accurate clamping due to shrink fit technology
High torque due to form closed clamping
No loss of accuracy
No pull out and no spinning ot the tool
Groove on tool shank is directed so that the tool will be pulled into the chuck (depending on direction of rotation)
