OVERVIEW OF OTEC ELECTRO FINISHING |
|
|
|---|
|
Electro Finishing, a process where workpieces rotate through abrasive materials, ensuring a uniform finish. OTEC's Electro Finishing involves suspending special polymer particles in an ionically conductive liquid, delivering outstanding results on materials such as silver, brass, stainless steel, steel, cobalt chrome, & titanium. This process offers several advantages: it is ideal for delicate components, applies low mechanical stress on workpieces, prevents bending or breakage, maintains dimensional stability, allows for lightweight & delicate holder designs due to low forces, & minimises edge abrasion. Electro Finishing is particularly suitable for sensitive & soft materials, leaving no micro scratches & improving corrosion resistance. It ensures no impact on microstructures & provides a clean, neat surface. For workpieces with complex geometries, Electro Finishing reaches deeper areas, avoiding media jamming thanks to tiny spherical finishing particles or pure liquid, achieving roughness values as low as Ra 0.01µm. Benefiting various industries, OTEC Electro Finishing is invaluable for: - Jewellery & Watchmaking: Ensuring mirror finishes & precise detailing, OTEC Electro Finishing offers non-destructive, ultra-smooth polishing of metals such as gold & silver.
- Medical & Dental: Medical & dental implants & instruments require extremely smooth, clean surfaces to reduce infection risk & ensure biocompatibility. OTEC Electro Finishing provides delicate polishing without altering tolerances or sharp edges, crucial for intricate components.
- Aerospace: Aerospace components demand high precision & fatigue resistance. Consistent surface finishing on complex geometries like turbine blades & gear parts, enhancing aerodynamics & longevity can be provided with OTEC Electro Finishing.
- Automotive: High-performance automotive parts, especially for motorsports & electric vehicles, benefit from surface treatments that reduce friction & wear. OTEC Electro Finishing automates the repeatable polishing & deburring of gears, shafts, & injection-moulded parts, boosting efficiency & quality.
- Toolmaking: Tools must maintain sharp edges while minimizing micro cracks or rough spots that can lead to early wear & breakage. Electro Finishing smooths tool surfaces without dulling them, increasing lifespan & cutting performance.
- Additive Manufacturing (3D Printing): Printed parts, especially metal ones, often have rough or inconsistent surfaces that need processing. OTEC Electro Finishing excels at finishing internal channels & complex geometries that are otherwise hard to reach.
OTEC Electro Finishing machines achieve high-quality surface finishes, enhancing the performance & aesthetics of components across various industries. For more information on OTEC Electro Finishing machines, contact us today! |
