一前言利用齿轮滚床铣制正齿轮及螺旋齿轮,与用万能卧式铣床铣切,方法上有基本差别。用万能卧式铣床铣齿,铣切过程为间歇的,系铣切一齿後,再铣切次一齿(或初铣一齿後再初铣次一齿),当中需经过齿轮坯分度手续,此手续系利用分度头(Index head)为之。而利用齿轮滚床铣齿,铣切手续 An introduction to milling spur gears and helical gears with a gear-rolling machine, and milling with a universal horizontal milling machine, there are fundamental differences in methods. With the universal horizontal milling machine, the milling process is intermittent. After one tooth is milled, the second tooth is milled (or the first tooth is milled after the first tooth is milled). For procedures, this procedure uses the Index head. The use of gear roller milling, milling process
