喷吸钻是一种较先进的高效刀具,比一般麻花钻、扁钻效率高2～4倍,且加工精度高、光洁度好、孔的直线性好。但是,一般结构的喷吸钻,刀杆内外管结构复杂、装卸不方便;内管选料及“月牙槽”的加工都较困难;由于钻头本身结构的限制,内管孔径不可能很大。因此,排屑不利,对断屑的要求特别严格,断屑台稍有损坏就有切屑卡死的危险。为了克服上述缺点,我们经反复试验,不断完善,成功地将喷吸钻的内外管结构,改为单管结构,
Spray suction drill is a more advanced and efficient tool, than the average twist drill, flat diamond high efficiency 2 to 4 times, and high precision, good finish, good linearity of the hole. However, the general structure of the jet suction drill, the structure of the cutter inside and outside the tube complex, inconvenient loading and unloading; inner tube material selection and “crescent groove” processing more difficult; due to the structure of the drill bit itself, the inner tube aperture can not be large. Therefore, adverse chip removal, the requirements of the chip breaking is particularly strict, chip breaker slightly damaged there is the risk of chip stuck. In order to overcome the above shortcomings, after repeated tests and continuous improvement, we succeeded in changing the internal and external pipe structure of the spray suction drill into a single pipe structure,
