MZG ADS Pull-Back Tool Holder System
MZG present a comprehensive and detailed introduction to the Pull-Back Tool Holder, also known as the ADS series. This advanced tool holding system is specifically engineered for a niche yet critical segment of manufacturing: ultra-high-speed and high-precision machining. Its unique clamping principle sets it apart from conventional collet systems, delivering superior performance where accuracy and surface finish are paramount.
Exceptional Concentricity and Runout Accuracy
Incredible runout accuracy consistently achieving ≤0.003mm through unique pull-back clamping mechanism that draws the collet backwards into precision-ground internal taper for perfect tool alignment.
Elite High-Speed Capability
Dynamically balanced to elite standard of G2.5 at up to 30,000 RPM, minimizing centrifugal forces and harmonic vibrations for remarkably stable cutting process and mirror-like surface finishes.
Enhanced System Rigidity and Stability
Pull-back action creates firm, positive lock on tool shank with enhanced rigidity. HSK-ADS models leverage dual-contact interface for simultaneous taper and face contact, dramatically increasing lateral stability.
System Performance Analysis
The performance of a Pull-Back Tool Holder is defined by its exceptional precision, high-speed stability, and the rigidity derived from its unique clamping design. The defining feature of the ADS system is its incredible runout accuracy, consistently achieving ≤0.003mm. This outstanding precision is a direct result of the "pull-back" clamping mechanism.
Instead of a nut pushing the collet forward into a taper, the ADS design actively draws the collet backwards into the holder's precision-ground internal taper. This action ensures the collet is perfectly and evenly seated every time, eliminating the minor inconsistencies that can occur in standard systems and resulting in near-perfect tool alignment.
To complement its precision, the ADS tool holder is dynamically balanced to an elite standard of G2.5 at up to 30,000 RPM. This high level of balance is essential for high-speed machining (HSM), as it minimizes centrifugal forces and harmonic vibrations, resulting in remarkably stable cutting process.
The pull-back action creates a firm, positive lock on the tool shank. The HSK-ADS models leverage the HSK dual-contact interface, providing simultaneous contact on both the taper and the face of the spindle, dramatically increasing rigidity against lateral forces for exceptional stability.
