HPEDM Launches 5axis Selfcentering Vise for Precision Machining

In modern manufacturing where extreme machining accuracy and efficiency are paramount, workpiece clamping stability and repeatable positioning directly determine final product quality. Traditional fixture solutions often struggle to meet the rigorous demands of five-axis simultaneous machining for complex curved surfaces and multi-angle positioning.

The HE-R06934.79 five-axis self-centering fixture features an innovative bidirectional self-centering mechanism. Through precision mechanical design, the fixture achieves automatic centering positioning in two directions, significantly simplifying the clamping process while ensuring highly consistent positioning accuracy with each operation.

The clamping range demonstrates remarkable flexibility: 0-79mm for forward clamping and 79-150mm for reverse clamping, accommodating a wide spectrum of workpiece sizes. This design not only enhances the fixture's versatility but also facilitates machining of complex-shaped components.

Engineered for maximum utility, the fixture incorporates interfaces compatible with both EROWA ITS and System 3R systems. Simple positioning plate installation enables seamless integration into existing automated production lines without requiring extensive equipment modifications.

Key application areas include:

• Five-axis/four-axis CNC machining centers: Provides stable workpiece support for both vertical and horizontal machining centers, meeting high-precision requirements for complex surface machining and multi-face milling.
• Precision grinding: Delivers essential stability for grinding operations demanding exceptional surface finish and dimensional accuracy.
• Electrical discharge machining (EDM): Ensures precise workpiece fixation critical for maintaining accurate machining paths during EDM processes.

The fixture measures 127mm in width, 153mm in length, and 75mm in height. Its most impressive technical achievement is a self-centering accuracy of 0.02-0.03mm - a leading specification in precision machining that maintains positioning errors within micron-level tolerances during repeated clamping operations.

This level of precision proves invaluable for industries requiring exceptional dimensional consistency and repeatable positioning, including aerospace, medical device manufacturing, and precision mold production.

Beyond precision improvements, the fixture reduces scrap rates caused by positioning errors while optimizing clamping processes to decrease changeover times. These combined benefits contribute to significant overall production cost reductions.
