数控外榫槽卧式侧拉床

涡轮盘和叶片榫槽拉床

Turbine disk and blade broaching machine

涡轮盘是航天工业和能源工业采用拉削技术zui主要的产品。涡轮盘的直径大小不一，盘中有放射状分布的榫槽。此榫槽的加工精度、表面粗糙度都要求非常高，加工材料都是高温合金，非常难以加工。因此，采用拉削是非常适应且较为经济的—种方法。拉削涡轮盘可根据被加工零件的实际情况采用大小不同的卧式拉床，采用分刀多级加工，我们也可采用拉削加工中心，具备自动拉削功能（备配刀具库）。

另外，我们也生产立式的拉削汽轮机叶片的拉床，叶片的拉削是一种非常典型的拉削过程，由于品种繁多，且表面粗糙度要求也高，我们生产各类立式、卧式低速拉床加工不同品种叶片。同时，更换夹具后，也可拉削涡轮盘榫槽。

侧卧拉床特点：

采用电气、机械驱动，平衡性更好，刀具寿命更长，粗糙度更好，行程大，主溜板上可一次装夹总长为4000mm的拉刀，并可同时装夹三排拉刀；工位数可根据需要增加；夹具可根据需要更换，便于拉削不同的品种。

Turbine disc and blade are main products adopts broaching in space

industry and energy industry The turbine disc has different size and there are radial mortise in disc. It is very hard to processing as mortise usually made by high-temperature alloy and requires high accuracy and good  surface  roughness. Thus, broaching is suitable and economical different horizontal.  

broaching machine is available for different parts. We can also choose broaching machining center that realizes auto broaching(With tool magazine).

Besides, we also produce vertical broaching machine for blade of steam turbine. Broaching of blade is a typical broaching. It has various kinds and requires good surface roughness, so we produce many models of vertical and horizontal broaching machine for different blades. At meantime, it can also broaching mortise of turbine disc after changing jigs.

Features of horizontal side broaching machine: It adopts electric and mechanical drive which with good balance. longer cutter life and better roughness. With long stroke. the main sliding plate can installed on broach of 4000mm and fix three rows broaches once. Fixture can change according to the requirements， for broaching different work piece.
