This is the D150 pneumatic reference chuck, specifically designed for the EROWA/3R system. Its core advantages include "extra-large diameter, pneumaticone-button locking, and ultra-high rigidity." It is a core tooling for thehigh-precision transfer of large, heavy-duty precision parts across equipmentand is widely compatible with five-axis machining centers, CNC grinders, CMMcoordinate measuring machines, and other applications.
Product Core Parameters and Structure
1.Key Specifications
Model:RHR1 D150 Pneumatic Chuck
Positioning Diameter: D150mm (standard ERWA/3R large-diameter interface), compatible withlarge pallets and fixtures
Drive Method: Pneumatic locking/unlocking, rapid automated response
Main Body Material: Japan Chromium Steel, quenched and tempered,hardness HRC 57~60
Core Accuracy: Repeat positioning accuracy ≤0.002mm, overall flatness ≤0.005mm
Installation Method: Bottom with mounting holes, can be directly fixed to the machine toolworktable or adapter plate
2.Core Structure Analysis
Top Clamping End: D150mm circular ITS interface, with 3 sets of high-precisionlocking jaws, achieving all-round fitting and locking of largepallets/fixtures.
Central Pneumatic Mechanism: Features a built-in high-rigidity cylinder, enablingone-button locking/unlocking via an air source interface (side air intake).Operation is easy and requires no manual force.
Base Panel: A square, high-strength base plate with multiple sets of universalmounting holes, allowing direct installation on standard machine toolworktables or use with other zero-point positioning bases.
Positioning Structure: Includes a built-in high-precision spring collet and positioningpin, achieving zero-clearance docking with the EROWA/3R D150 standard pallet,ensuring long-term high-precision operation.
Core Advantages:
1.D150 Extra-Large Diameter, Suitable for Large/Heavy Workpieces
The D150mm standard interface is perfectly compatible with EROWA/3R large electrodepallets and fixture plates.
Suitable for clamping precision parts/mold inserts with a diameter ≤150mm andconsiderable weight, solving the pain points of traditional fixtures such assmall clamping surface and insufficient stability.
2.Pneumatic One-Button Operation, High-Efficiency Automation
Purely pneumatically driven, locking/unlocking takes only 3 seconds, offering rapidresponse and eliminating manual locking deviations.
Especially suitable for automated production lines, robotic loading and unloading, andunmanned processing scenarios, significantly improving uptime.
Flexible manual/automatic switching adapts to different production mode requirements.
3.Micron-Level Positioning, Maximizing Processing Consistency
Repeatability≤0.002mm, flatness ≤0.005mm, ensuring 100% consistency in size and positionwhen switching between CNC, EDM, and CMM.
High-precision locking jaws and a closed structure guarantee no shifting or vibration duringhigh-speed cutting and heavy-load processing.
4.High Rigidity and Durability
The main body is made of HRC 52-58 high-strength mold steel, precision ground,offering high rigidity, resistance to deformation, and vibration.
The fully enclosed waterproof and chip-proof structure is suitable for harshcutting environments such as CNC, EDM, and grinding machines, and has a servicelife of 8-10 years.
