Power Shrink Chuck
DIN 69893-1 · HSK-A125
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 internal groove in the clamping bore
- With Cool Jet bores that can be sealed (Thread M4) and 6 bores
- Higher coolant flow rate due to optimized coolant bores
- Cooling with Cool Flash for an extra charge
The long versions (A = 160 and 200 mm) 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
