| 详细介绍： 立式内拉床
本机床用于拉削各种几何形状的通孔，生产效率高，适于成批生产及大量生产。
本机床采用液压传动，工作平稳，能无级调速，并有超负荷保险装置。机床的工作台为固定式，有护送刀装置，可作自动循环、半自动循环、分段循环（Ⅰ、Ⅱ）及调整等五种运动，能适应不同拉削形式的需要。
These machines are designed for broaching holes of various geometrical forms in mass and batch production with high efficiency.
The machines are driven by hydraulic power with smooth transmission and their speed can be adjusted steplessly. A safety device against overload is provided in its hydraulic system and a broach hand-ling mechanism is equipped on the machines with tables being fixed. Being able to be operated in five kinds of motions as automatic cycle, semi-automatic cycle, step-by-step cycles （Ⅰ、Ⅱ）and adjustment, the machines can even meet the requirements of various kinds of broaching.
