端铣刀(发明证书4856252)是一种在铣床上使用的先进切削工具。铣刀刀体5是一个圆盘,在圆盘的下平面上做出有侧向垂直槽的开口孔,而在中央部位装有调整螺栓,在其开口孔内布置回转变距导筒6,每个回转变距导简内都装有作成截圆锥体形状的切削元件1,截圆锥体用带保持套4的专用滚针轴承3定中心。为了防止切削元件尾部的轴向位移,装有用螺母8固定的向心推力轴承7。轴承2用压紧的螺纹衬套密封。回转变距导筒的尾部9用球形头通过凹形槽与可调螺纹环10相接触,而螺纹环自行定基准或者拧到中心调整螺栓13上。在铣刀体内有带侧边槽的开口孔,变距导筒轴H被配置和保持在开口孔内。铣刀用螺栓12固定在铣床主轴11的接盘上,动力键14能减轻加固
End Mill (Certificate of Invention 4856252) is an advanced cutting tool for use on milling machines. Milling cutter body 5 is a circular disc, made in the lower plane of the disc has a vertical hole vertical opening, and in the central part of the adjustment bolt, the opening hole in the variable pitch guide tube 6, Each rotary pitch change guide Jane is equipped with a frusto-conical cutting element 1, the truncated cone with a retaining sleeve 4 dedicated needle bearing 3 centering. In order to prevent the axial displacement of the rear end of the cutting element, equipped with a nut 8 fixed radial thrust bearing 7. Bearing 2 is sealed with a compression threaded bushing. The tail section 9 of the slewing range guide tube is brought into contact with the adjustable thread ring 10 by the spherical head through the concave groove and the thread ring is self-aligning or screwed onto the center adjusting bolt 13. In the milling cutter body, there is an opening hole with a side groove, and the variable guide shaft H is arranged and held in the opening hole. Milling cutter with bolts 12 is fixed on the milling spindle 11, the power key 14 can reduce the reinforcement
