Product processing parameters
Material: high-purity alumina ceramic (Al₂O₃≥99.7%)
Processing features: aircraft engine blade surface (φ100×18mm)
Key indicators: HV1760 hardness, Ra0.4μm surface roughness requirements
Industry processing pain points
A. Material property challenges
• Temperature resistance of 1600℃ but significant brittle fracture tendency (keywords: alumina ceramic edge collapse control)
• Traditional grinding produces sub-surface cracks of ＞50μm (keywords: hidden damage to ceramic parts)
B. Traditional process defects
Diamond grinding head single piece consumption cost ￥420 (keywords: ceramic processing tool cost)
Contour accuracy ±0.1mm is difficult to meet the standard (keywords: blade surface accuracy requirements)
Polishing process accounts for 60% of the working time (keywords: ceramic post-processing bottleneck)
MID SolutionsInnovative technology
Five-axis ultrasonic machining center: 0.003mm dynamic accuracy (keywords: ceramic special five-axis machine tool)
Supercritical CO₂ cooling: -78℃ low temperature to inhibit crack propagation (keywords: low temperature ceramic grinding technology)
Nano lubricant MQL system: cutting force reduced by 37% (keywords: ceramic processing micro-lubrication)
