MZG Hydraulic Tool Holder System
MZG Tool Machine Company offer a comprehensive and authoritative overview of the Hydraulic Tool Holder system. This technology represents a significant advancement in precision tool clamping, engineered specifically for applications where ultimate accuracy, superior surface finish, and vibration-free machining are non-negotiable.
Superior Vibration Damping
Internal hydraulic fluid acts as a shock absorber, absorbing micro-vibrations for remarkably stable cutting action and superior surface finishes that often eliminate secondary polishing operations.
Unparalleled Precision and Concentricity
Hydraulic system provides 360-degree uniform pressure with guaranteed runout of ≤3µm, ensuring exceptional centering accuracy and near-perfect concentricity for superior dimensional accuracy.
High-Speed Machining Capability
Precision balanced to G2.5 grade for stable operation up to 25,000 RPM, enabling high-speed finishing strategies while maintaining exceptional surface quality and process stability.
System Performance Analysis
The performance of Hydraulic Tool Holders is defined by a unique combination of high precision, exceptional vibration damping, and operational simplicity. The core performance feature is its inherent ability to dampen vibrations through a sealed hydraulic fluid reservoir that acts as a highly effective shock absorber, absorbing high-frequency micro-vibrations generated during machining.
Our HM hydraulic series guarantees a runout of ≤3 micrometers (µm) through 360-degree uniform hydraulic pressure that centers the tool shank with near-perfect concentricity. Unlike mechanical collet systems, the hydraulic system self-centers the tool every time, ensuring consistent ultra-low runout critical for finishing and precision applications.
All models are dynamically balanced to G2.5 grade for speeds up to 25,000 RPM. This superior balance minimizes centrifugal forces and harmonic resonance at high rotational speeds, making them perfectly suited for high-speed finishing strategies that reduce cycle times while enhancing surface quality.
The hydraulic system provides consistent and reliable clamping force with simple hex wrench actuation, ensuring the same clamping pressure is applied with every tool change, eliminating operator variability and providing excellent process security for high-value machining operations.
