Ultra-precision machining is a machining process dedicated to the production of ultra-precise micro-parts and microfluidic chip moulds for applications in medicine, optics, semiconductors and precision engineering.
Product Description
Ultra-precision machining refers to the use of equipment and tools lower than the accuracy of the workpiece, through the process means and special process equipment, processing the required workpiece, applicable to single-piece, small batch production. Ultra-precision machining has very high accuracy and surface quality requirements, which is characterised by the back draft less than the size of the grain, cutting in the grain, and the traditional cutting mechanism is completely different. Ultra-precision machining is usually used to manufacture high-quality products in the fields of optical components, semiconductor chips, high-end medical devices and precision mechanical parts. Its processing difficulties lie in how to effectively control the formation of defects and improve processing accuracy, to achieve ultra-precision polishing methods mainly include small grinding head CNC polishing, airbag polishing, ion beam polishing, magnetorheological polishing, plasma polishing, jet polishing and so on. China's optical ultra-precision processing technology and equipment development level in astronomical telescope systems, strong laser devices and other fields to achieve independent control, but in the photolithography objective lens as a representative of the extreme precision optical components of ultra-precision machining and foreign advanced level there is a large gap.
