- High-endization: The penetration rate of ceramic-bonded CBN grinding wheels in the high-end market has increased from 12.4% in 2020 to 28.6% in 2025, becoming a rigid demand in the aerospace field.
Key Notes on Translation
1. Industry-specific Terms: "砂轮片" is uniformly translated as "grinding wheels" (the standard term in the abrasives industry); "CBN" (Cubic Boron Nitride) retains the international abbreviation for professional recognition.
2. Standards & Regulations: "GB/T 2485-2016" and "ISO 12413" keep their original codes; "REACH" (Registration, Evaluation, Authorization and Restriction of Chemicals) is supplemented with its full name for clarity.
3. Data Units: "亿元" is converted to "RMB billion" (1 亿元 = RMB 0.1 billion) to align with international data expression habits; "Ra0.2μm" retains the original surface roughness notation (common in engineering).
