Description

1. Technical field [0001] The invention belongs to special processing technology, in particular to a precision fine abrasive water jet energy storage type pulse micro-feeding system used in precision fine abrasive water jet processing equipment. 2. Background of the invention [0002] Abrasive water jet processing is a new type of special energy beam processing technology produced in the 1980s. Due to its advantages of small processing force, small thermal impact on materials, and a wide range of machinable materials, it has developed rapidly in the past 20 years. , is increasingly widely used in practical engineering. In recent years, abrasive water jet processing technology has developed from rough processing such as cutting to surface polishing, micro-etching, micro-hole processing and other micro-precision processing. [0003] In abrasive water jet processing, the mixing of water jet and abrasive is generally divided into two ways: pre-mixing and post-mixing. The pre-m...
