重特大型工件深孔加工BTA装置的研制

Development of BTA for processing deep holes of heavy super large parts

经研究与实际应用,将BTA深孔钻加工技术移植到落地镗床上加工非回转体工件上的深孔,取得了成功,彰显出镗床用BTA深孔装置加工非回转体工件上深孔的特色。

After researching and application, we make a success of technology migration from BTA deep hole machining to heavy and large non-rotational part deep holes machining on floor type boring machine, the main design is the feature of machining heavy and large non-rotational part deep hole with BTA equip- ment on boring machine.
