This is the RHT4 adjustable wire EDM fixture, specifically designed for slow wireEDM (WEDM). Compatible with EROWA/3R systems, its core advantages are"precise adjustability, efficient clamping, and stable durability,"making it an ideal tooling for high-precision wire EDM machining of precisionmolds, electronic components, medical devices, and other applications.
Product Core Parameters and Structure
1.Key Specifications
Model:RHT4 Adjustable WEDM Chuck
Adjustment Range: Bidirectional adjustment for X/Y axes, adjustment stroke ±5mm (largerstroke customizable)
Clamping Range: Adapts to workpieces/electrodes ranging from 0 to 50mm in size,compatible with EROWA ITS 25/50 standard interface
Main Material: Japan Chromium Steel, quenched and tempered, hardness HRC 57~60
Core Accuracy: Repeat positioning accuracy ≤0.002mm, adjustment resolution ≤0.001mm
2.Core Structure
Front Clamping End: Compatible with EROWA standard quick-change interface, allowingfor rapid clamping of electrodes/workpieces, featuring a self-centering lockingstructure for secure clamping without offset.
Middle Adjustment Module: Bidirectional precision lead screw adjustment for X/Y axes,enabling micron-level fine-tuning and correction of machining position withoutdisassembly.
Base:High-strength, lightweight, hollow design, providing high rigidity and reducedweight. Pre-drilled mounting holes at the bottom allow for direct mounting tothe wire EDM machine's worktable.
Locking Mechanism: Side-mounted locking screws provide one-click locking afteradjustment, ensuring no positional drift during machining.
Core Advantages:
1.Micron-level Adjustability, Precise Error Correction: Adjustable in both X andY directions with a resolution ≤0.001mm, allowing for online correction ofworkpiece/electrode positional deviations and preventing scrap due to clampingerrors.
Fine-tuningcan be completed without disassembling the workpiece, significantly reducingre-clamping time, making it particularly suitable for high-precision wire EDMmachining of complex cavities and irregular holes.
2.Efficient Clamping, Compatible with Standardized Systems: Front-end compatiblewith EROWA ITS 25/50 standard interface, enabling "offline pre-adjustment+ on-machine quick change," reducing clamping time to within 30 seconds.
The base can be directly fixed to the wire EDM machine tool, or it can be equippedwith a zero-point positioner to achieve zero-point transfer across equipment(EDM→WEDM→CNC).
3.High rigidity and stability ensure machining quality. The high-strength moldsteel body is precision ground, resulting in high rigidity and resistance todeformation, ensuring vibration-free and displacement-free operation duringhigh-current wire EDM.
The hollow design balances lightweight design with rigidity, reducing machine toolload while facilitating coolant flow and chip removal.
4.Durable and easy to maintain, suitable for harsh environments. The fullyenclosed adjustment mechanism is waterproof, chip-proof, andcorrosion-resistant, adapting to the humid and chip-prone environment of wireEDM machines.
Themirror-polished surface is not prone to slag adhesion, requiring only dailycleaning and rust prevention maintenance, with a normal service life of 8-10years.
