摇臂钻床和立式钻床的发展远景可分成两个阶段:1.在三、五年内即可达到的远景;2.距目前较远的远景。 1三、五年内可实现的远景 众所周知,机床的结构是随着工具的改进而改变的。当硬质合金出现后,机床结构也就相应的起了新的变化来满足新的需要,要求钻床具有更高的切削速度、刚 Radial drilling machines and vertical drilling machine development prospects can be divided into two phases: 1. In three to five years to achieve the long-term perspective; 2. Far from the current perspective. 1 Three, the long-term vision that can be realized in five years As we all know, the structure of the machine is changed with the improvement of tools. When the cemented carbide appeared, the machine structure also correspondingly took on new changes to meet the new needs, requiring a higher cutting speed drilling machine, just
