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 an improved construction and a specially coated smooth locknut combines high rigidity with vibration damping and noise reduction. This protects the machine, spindle, and tool. The High Precision Collet Chuck is particularly suitable for micro and fine machining (e.g., in medical technology and the watch industry).
High Precision Collet Chuck, DIN 69893-5, HSK-E25
- 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 < 1 gmm
