本文通过笔者在HTB—Ⅲ型三轴数控深孔钻床上,用国产BTA型深孔钻头与进口钻头的钻孔比较,提出国产深孔钻头的使用要求:同时指出钻头制造质量上存在的问题,可供使用和制造厂家借鉴。我国的深孔加工技术,越来越广泛地应用于机器制造业中,哈尔滨锅炉厂在加工二氧化碳汽提塔的管板时,同时使用了国产BTA型钻头与进口钻头,通过使用比较,认为国产钻头有其独到优点,只要使用得当,在钻头使用寿命上能赶上进口的BTA钻头。
This article through the author in the HTB-Ⅲ type three-axis CNC deep hole drilling machine, with the domestic BTA-type deep hole drill bits and drill bits compared to the proposed domestic deep-hole drill requirements: At the same time that the quality of bit manufacturing problems, Available for use and manufacturer reference. China’s deep-hole processing technology, more and more widely used in machine building industry, Harbin Boiler Factory in the processing carbon dioxide stripper tube plate, while using the domestic BTA-type drill bits and imported drill bits, through the use of comparison, that the domestic Drill bit has its own unique advantages, as long as the use of properly, in the life of the drill bit to catch up with imported BTA drill.
