Albrecht ER Micro-Chucks
- These unique one-piece toolholders provide extra reach and support for your drills and endmills when using driven tooling.
- Exceptional accuracy and rigidity for:
- More aggressive chip removal
- Faster cycle times
- Improved cutting tool life
- Integral ER body, super slim nose, and ultra-precision collets work in unison for optimized clearance and superior vibration dampening over shrink-fit holders.
- Cutting tool life significantly extended.
- Available in three popular ER configurations for compatibility with many brands of driven tools.
- Ultra-precision accuracy – 3 microns (0.00012″) at 2.5 x diameter.
- High-speed balanced to G2.5@40,000 rpm.
- Collets are available from stock in both inch and metric sizes with a choice of precise coolant delivery options:
- Standard – coolant is directed through the collet slots over the cutting tool
- Sealed – coolant is directed through the center of the cutting tool (for cutting tools that have central coolant ports)
- Simple axial tightening reduces setup time.
The Old Method
- Small diameter cutting tools flex under load
- Excessive vibration
- Less than optimal cycle times
The Albrecht Method
- Cutting tools supported over greater length
- Superior rigidity, accuracy, and dampening
- Faster cycle times
Simple, axial tightening of the collet keeps the tool on centerline and enables fast changeover.
Benefit from additional cutting tool support while maintaining excellent clearance in tight areas.
Integral ER body optimizes rigidity and vibration dampening.
