• Quick comparison: Rapidly determine the surface roughness grade of workpieces through visual and tactile inspection.
• Multi-process coverage: Typically includes various machining surfaces such as turning, milling, planing, grinding, and boring.
• High-precision replication: Utilizing electroforming or precision engraving techniques to accurately replicate standard roughness values.
• Wear-resistant material: Typically made of nickel or high-quality steel, it is sturdy, durable, and resistant to deformation.
• Field Practicality: No need for complex electronic equipment, suitable for use in workshops and production lines.
• Easy to operate: Simply swipe with a fingernail or touch probe to compare the sample block with the workpiece.
• Compliant with standards: Strictly manufactured in accordance with international or national standards such as ISO and GB/T.
• Rust-proof design: The surface is treated with excellent anti-rust and corrosion resistance properties.
