Description

technical field [0001] The invention relates to the field of numerical control processing equipment, in particular to a three-axis numerical control deep hole drilling machine for processing multiple deep hole workpieces. Background technique [0002] Gun drilling, BTA drilling, jet suction drilling and other deep hole processing are special processing technologies. Through one continuous drilling, the processing accuracy and surface roughness that can only be achieved by drilling, expanding and reaming processes can be achieved. Due to the limitation of technical level and previous processing requirements, the existing deep hole processing machine tools are mostly transformed from conventional machine tools, including deep hole drilling and boring machines, deep hole grinding machines, deep hole honing machines and deep hole processing machine tools transformed from ordinary lathes, etc. . This type of machine tool realizes deep hole processing through the rotating motion ...

Problems solved by technology

This type of machine tool realizes deep hole processing through the rotating motion of the workpiece or the tool and the reciprocating motion of the tool. This processing method is more suitable for single deep hole processing. However, with the development of modern deep hole processing technology, various types, The proportion of large-scale and high-precision machining is increasing, especially the processing of large-scale multi-deep hole workpieces, which puts forward higher requirements for deep hole processing technology. How to ensure the consistency, accuracy and speed of multi-hole machining positioning, and How to improve processing efficiency and reduce production costs are technical problems that are difficult to overcome for existing deep hole processing machine tools
