SyM640A，double surface lapping machine，also named polishing machine, is widely used on polishing process of two sides in machinery, electronic industry and others. Used for product degree of parallelism, flatness, dimensional tolerance controled whithin 0.003mm. surface roughness under Ra0.2um. Especially for high precision, fragile thin part, can working excellent quality in producing.
At present, this series models, have been widely used in silicon, germanium, crystal, glass, ceramics, sapphire, gallium arsenide, ferrite, such as lithium niobate non-metallic sheet body, and the valve plate, valve plate, a friction plate, rigid seal, piston rings and other metal parts
Processing, and achieved excellent results.
