Jlypt’s Surface Finish Chart: An In-Depth Look
Below is a detailed table showcasing Jlypt’s surface finish chart, which categorizes finishes based on their Ra (Arithmetic Mean Deviation) values and textures.
| Finish Code | Ra (μm) | Texture Description | Common Applications | CNC Processes |
|---|---|---|---|---|
| JF-1 | >12.5 | Very coarse, directional | Agricultural tools | Rough milling |
| JF-2 | 3.2 – 6.3 | Coarse, uniform | Construction equipment | Turning |
| JF-3 | 0.8 – 1.6 | Fine, slightly textured | Automotive parts | Grinding |
| JF-4 | 0.2 – 0.4 | Smooth, semi-mirror | Electronics casings | Polishing |
| JF-5 | <0.2 | Mirror-like, defect-free | Medical instruments | Superfinishing |
Real-World Case Studies
Case Study 1: Aerospace Components
Material: Titanium Alloy
Surface Finish Requirement: JF-5 (Ra < 0.2μm)
Challenge: Aerospace components require an exceptionally smooth surface to ensure airtight seals and minimize friction.
Jlypt Solution: We employed a combination of precision grinding and diamond polishing to achieve the desired mirror-like finish. The final surface was verified using a white light interferometer to ensure compliance with JF-5 standards.
Outcome: The components exhibited exceptional performance, meeting the rigorous standards of the aerospace industry.
Case Study 2: Precision Medical Instruments
Material: Stainless Steel
Surface Finish Requirement: JF-4 (Ra 0.2 – 0.4μm)
Challenge: Medical instruments need a smooth surface to facilitate easy cleaning and reduce the risk of infection.
Jlypt Solution: We used electrochemical polishing to achieve the JF-4 finish. This process removed all burrs and imperfections, leaving a uniform, semi-mirror surface.
Outcome: The instruments met the highest standards of cleanliness and functionality, ensuring patient safety.
Case Study 3: High-End Automotive Trim
Material: Aluminum Alloy
Surface Finish Requirement: JF-3 (Ra 0.8 – 1.6μm)
Challenge: Automotive trim pieces need a fine texture that enhances aesthetics while maintaining durability.
Jlypt Solution: We utilized vibratory finishing with ceramic media to create a uniform, fine texture that met the JF-3 standards. The process also removed any machining marks, leaving a smooth, appealing surface.
Outcome: The automotive trim pieces added a touch of luxury to the vehicles, enhancing their overall appeal.
