YH2M8432C/13B-9L/8432E/8436B/18B High precision vertical double-side surface lapping machine
Main Function:
It is used for the lapping/polishing of double surfaces of metal parts, such as valve plate, rigid seal ring, oil pump blade, as well as laminated non-metal parts of hard & brittle materials like silicon, germanium, quartz, glass, ceramic, sapphire, gallium arsenide, ferrite, lithium niobate, etc.
Typical Applications
This equipment is mainly used for lapping and polishing both sides of the parallel surface of thin metal and hardbrittle nonmetal parts, such as silicon, sapphire crystal, ceramic, optical glass, quartz crystal and other semiconductor materials.
