Power Shrink Chuck
similar JIS B 6339 · BT50 with face contact
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 speed, higher feed and larger cutting depth
- Shorter processing times
- Quieter running, therefore better surface quality and protection of tools, spindles and machines
- Higher machining accuracy
- With threaded holes in order to balance with balancing screws
- Cool Jet bores that can be sealed included
- Cooling with Cool Flash for an extra charge
The oversize and ZG200 versions with slim tips are especially versatile to use.
- 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
