①HIWIN RGH55CA Linear Guideway For Electric Discharge Machines
The HIWIN RGH55CA Linear Guideway redefines precision motion control for electric discharge machining (EDM), where micron-level positioning accuracy and exceptional stability are critical for achieving flawless surface finishes and intricate geometries. Specifically engineered to thrive in the unique environment of spark erosion machining, this heavy-duty guideway system maintains unwavering precision despite the constant micro-vibrations and thermal fluctuations inherent to EDM processes. The RGH55CA's advanced roller technology ensures buttery-smooth axis movements during delicate electrode positioning, enabling the creation of complex cavities and fine details in hardened tool steels, carbides, and exotic alloys with sub-micron repeatability. Its corrosion-resistant construction withstands the dielectric fluid environment while specialized seals prevent contamination from EDM byproducts that could compromise long-term accuracy. The guideway's exceptional damping characteristics absorb high-frequency vibrations during fine-finishing passes, crucial for achieving mirror-like surface quality in mold cores, aerospace components, and medical implants. Thermal-stable design elements counteract the gradual heat buildup during prolonged machining sessions, maintaining consistent positioning accuracy through marathon EDM operations. Whether integrated into sinker EDM machines for intricate die production or wire EDM systems for precision cutting applications, the RGH55CA provides the foundation for achieving superior edge quality and dimensional precision in the most demanding electrical discharge machining applications. By combining the rigidity needed for heavy electrodes with the finesse required for micron-level spark control, this linear guideway helps EDM operators push the boundaries of what's possible in precision machining - delivering results that meet the exacting standards of tool and die making, aerospace component manufacturing, and high-precision industrial applications where conventional machining reaches its limits.
②Drawing of RGH55CA
③Model Number of RG Series
④Construction of RG Series
1.Rolling circulation system: Block, rail, end cap, Circulation path, rollers
2.Lubrication system: Grease nipple and piping joint
3.Dust protection system: End seal, bottom seal,bolt cap, double seals and scraper.
⑤Features of RG series
The new RG series from HIWIN features a roller as the rolling element instead of steel balls. The roller series offers super high rigidity and very high load capacities. The RG series is designed with a 45-degree angle of contact. Elastic deformation of the linear contact surface, during load, is greatly reduced thereby offering greater rigidity and higher load capacities in all 4 load directions.The RG series linear guideway offers high performance for high-precisionmanufacturing and achieving longer service life.
1. Optimal design
FEM analysis was performed to determine the optimal structure of the block and the rail. The unique design of the circulation path allows the RG series linear guideway to offer smoother linear motion.
2.Super high rigidity
The RG series is a type of linear guideway that uses rollers as the rolling elements. Rollers have a greater contact area thanballs so that the roller guideway features higher load capacityand greater rigidity. The figure shows the rigidity of a roller and a ball with equal volume.
3. Super high load capacity
With the four rows of rollers arranged at a contact angle of 45-degrees, the RG series linear guideway has equal load ratings in the radial, reverse radial and lateral directions.The RG series has a higher load capacity in a smaller size than conventional, ball-type linear guideways.
4. Operating life increased
Compare with the ball element, the contact pressure of rolling element is distributed on the line region. Therefore,stress concentration was reduced siginificantly and the RG series offers longer running life. The nominal life of RG seriescan be calculated by using Eq.
