英国 Sterling 枪钻公司最近研制出一种叫做 speedbit 的深孔钻削装置,其主要特点是可以装在普通机床上,不需要专用枪钻机床就能进行深孔钻削。枪钻是一种成熟的精密深孔加工方法,它具有高效率、高精度(包括孔径、圆度和直线性等精度)和光洁度好等优点。但是,枪钻加工一般要 Sterling Gun Drilling recently developed a deep-hole drilling device called speedbit, the main feature is that it can be installed on a common machine tool, do not need a dedicated gun drilling machine can be deep-hole drilling. Gun Drill is a sophisticated precision deep-hole machining method with high efficiency, high accuracy (including accuracy of aperture, roundness and linearity) and good finish. However, gun drilling is generally required
