High-Purity Alumina Ceramic Grinding Plate yePrecision Lapping
St.Cera'sndiro yekukuya yeceramicInogadzirwa kubva pa99.8% high-purity alumina (Al₂O₃) yekushandisa pakukwesha nekukwesha nemazvo. Kugona kwedu kukwesha nemazvo kunoita kuti 0.003mm isatsvedzerere, 0.002mm iite seyakafanana, uye 0.002mm iite seyakafanana, uye 0.1 inenge yave pamusoro peplate. Plate iyi ine simba rekudzivirira kupfeka zvakanaka (Vickers 16 GPa), flexural strength (361 MPa), uye thermal stability inosvika 800°C. Inowanikwa muchimiro chedenderedzwa kusvika 600mm dhayamita uye rectangular plates inosvika 1500mm kureba. Nzvimbo dzine grooved (groove wide 0.5–2.0mm) dzinowanikwa kuti dzigoverwe mu lapping process. Plate yega yega inoongororwa ne laser interferometer uye inopihwa mushumo wekuyera nemazvo.
