目前,我国生产的牛头刨床,机动化程度较低,一般都没有自动抬刀机构。当精加工平面或切槽时,为了保证加工精度和获得较细的表面粗糙度,在刨刀进刀离开工件时,操作者必须用手提起刀夹,不仅劳动强度大,而且操作不安全,对使用多有不便。 At present, the shaper produced in China has a low degree of motorization and generally does not have an automatic knife carrying mechanism. When finishing the plane or grooving, in order to ensure the machining accuracy and obtain the fine surface roughness, the operator must lift the tool holder by hand when the sharpener feeds the workpiece, which is not only labor-intensive but also unsafe to operate. Use more inconvenience.
