For clamping tools with cylindrical shank in HAIMER Power Collets and ER collets according to ISO 15488.
The High Precision Collet Chuck is the collet chuck for the highest machining capacity in high-speed manufacturing. The optimized design with better construction combines high rigidity with vibration dampening and noise-reducing features, giving more protection to machines, spindles and tools. The universal High Precision Collet Chuck is a unique high performance chuck that can also be used with standard collets.
Description
High Precision Collet Chuck, similar JIS B 6339-2, BT40 with face contact
Quality pass
Chuck Body fine balanced G2.5 30.000 rpm or U
All functional surfaces fine machined
More accurate than DIN
- Additional support on the flange surface for more rigidity
- High runout accuracy: 0.003 mm at 3 × D with HAIMER Power Collets
- Also suitable for standard collets ER according to ISO 15488 (Please note when use with standard ER collets the gage length A will vary.)
- High rigidity
- Smoother running thanks to vibration absorbing geometry, therefore better surface quality and protection of tools, spindles and machines
- Increased machining capacity due to higher spindle speeds, higher feed rates and larger cutting depths
- Shorter processing times, higher machining accuracy, high clamping force
- Equally suited to high-speed manufacturing and heavy milling
- With threaded holes in order to balance with balancing screws
- With a specially coated smooth locknut, balanced at < 1gmm
HAIMER TIP
For a constant and acurate cooling of te cutting tool we recommend Power Collets with Cool Jet.
