Deep hole drilling machine is a kind of special machine tool for deep hole processing with high precision, high efficiency and high automation. Depending on advanced hole processing technology (gun drill, BTA drill, spray suction drill, etc.), the processing accuracy and surface roughness can be achieved by one continuous drilling process, which generally requires drilling, expanding and reaming processes. Machining hole size accuracy: IT7-IT11; Machining hole deviation: <0.5-1/1000 (Machining hole depth); Machining hole surface finish: Ra0.2-6.3um. It can carry with truss or joint robot and automatical line.
