A Study on the Charactdristics of CNC Deep Hole Maching for Marine Part Materials with the Sintered Carbide Gun Drill

초경합금 Gun Drill에 의한 박용 부품 재료의 CNC 심공가공 특성에 관한 연구

The gundrill is capable of machining for having large length to diameter ratio in single pass. The techniques of gundrill and gun boring began developing in the late 18th century with the need for more accurate bores in rifle, cannon, machinery part and marine part etc. The main feature of the gun drilling provides a stabilizing cutting force resultant necessary for self guidance of the drill head. A study of the accuracy and surface finish of holes produced would reveal quite useful information regarding the process. The thesis deals with the experimental results obtained during gun drilling on marine part materials for different machining conditions.
