有一较低精度（10级）,较小模数（m_n=1）,少齿（z=5）,大螺旋角（β=83°）齿轮,在普通万能卧铁上附加设计—铣头、工件夹持在车头（装于工作台）后不用分度,可多刀一次铁削成形,现介绍如下: 1.铣头及附加装置 （1）刀具传动。为简化刀架制造与有利于安装调试,可把铣头设计成组合式（见图）,把两块铸铁挂脚紧固在卧铣横梁的燕尾导轨上。长方形刀架夹持在两挂脚之间,用螺栓固定。在铣床主轴锥孔中接出一传动轴,轴头上装一锥齿轮（最好用螺旋锥齿轮）与刀具轴
There is a lower accuracy (10 levels), a smaller modulus (m_n = 1), fewer teeth (z = 5), large helix angle (β = 83 °) Workpiece clamping in the front (mounted on the table) without indexing, multi-knife can be an iron shaper forming, are described as follows: 1. Milling head and additional devices (1) tool drive. In order to simplify the manufacture of the tool holder and facilitate the installation and adjustment, the milling head can be designed as a combination (see picture), and the two cast iron hanging legs are fastened on the dovetail guide rail of the horizontal milling beam. Rectangular knife holder clamped between two hanging legs, bolted. Cone hole in the milling spindle connected to a drive shaft, the shaft head mounted a bevel gear (preferably spiral bevel gear) and the tool axis
