Power Shrink Chuck, similar JIS B 6339-2, BT50 with face contact

Quality pass

Chuck fine balanced G2.5 at 25.000 rpm

All functional surfaces fine machined

Taper tolerance AT3

Coolant supply form JD/JF

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.

Additional support on the flange surface for more rigidity
Increased machining capacity due to higher spindle speed, higher feed and larger cutting depth
Shorter processing times
Higher machining accuracy
Quieter running, therefore better surface quality and protection of tools, sindles and machines
With threaded holes in order to balance with balancing screws
Cool Jet bores that can be sealed included
High rigidity
Slim at the tip
Dampen vibrations
High clamping force
Equally suited to high-speed manufacturing and heavy milling
Universal usage, saves space in tool magazine

Scope of Delivery

With backup screw

HAIMER TIP

For RPM higher 8000 U/min we recommend the optional cooling system Cool Flash. (on request)

The most important features:

1. High runout accuracy (< 0.003 mm)
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)

Machining example Power Shrink Cuck

Milling - Ø: 16 mm; n = 13.000 1/min, Feed rate: vf = 5,2 m/min
Right: Power Shrink Chuck (Length: A = 160 mm, cutting depth: ap = 3,6 mm)
Left: Standard Shrink Chuck (Length: A = 160 mm; Cutting depth: ap = 1,8 mm)

Cool Jet (optional)

Optimized coolant bores, aimed at center
Coolant directly to the cutting edge
Extended tool life up to 100%
Higher reliability of cutting process
No more balls of chips on tool
Cool Jet starting from shank diameter 6 mm

Cool Flash (optional)

Optimized coolant bores with coolant outlet through slots
Coolant directly to the cutting edge
Extended tool life up to 100%
No more balls of chips on tool
Optimized runout accuracy! No additional unbalance! No disturbing clearance!
Cool Flash available for shank diameter 6 - 25 mm
