holding the work. 译文:牛头刨床的刀具和挡板位于骨枕。切削片在 前进冲程的过程中被剥落。“T”型的可调节工作台 - 工件槽,台钳,和其他用于固定工件的夹具。
The shaper has a rocker arm(摇臂) which drives the ram, and a mechanism for regulating the length of the stroke(冲程) The ram supports the tool head. The head carries the down-feed (向下进刀) mechanism and will swivel from side to side to permit the cutting of angles. This is generally hand feed, but some shapers are equipped with a power down-feed in addition to the regular hand down-feed.
with one end, while the other end of the arbor rotates in the bearing mounted on the arbor yoke(刀杆座). 译文:铣刀安装于刀杆上,通过垫片或者套筒进行定 位。刀杆的一端固定于主轴上,刀杆的另一端则安装 于刀杆座上的回转轴承上。

牛头刨床
金属切削加工设备,利用住复运动的刀具切割已固定在 机床工作平台上的工件〔一般用来加工较小工件)。机床 的刀架似牛头,故名。滑枕带着刨刀,作直线住复运动 的刨床,因滑枕前端的刀架形似牛头而得名。牛头刨床 主要用于单件小批生产中刨削中小型工件上的平面、成 形面和沟槽。 牛头刨床的主运动为电动机→变速机构→ 摇杆机构→滑枕往复运动;牛头刨床的进给运动为电动 机→变速机构→棘轮进给机构→工作台横向进给运动。
磨床
磨床使用磨粒进行切削,磨粒粘接在一起形成 不同形状不同尺寸的砂轮和砂带用于切削。磨 削可以带来高质量的工件表面。另外,工件的 尺寸精度在磨削过程中以0.00025的精度得到提 高。使用不同种类的磨床可以加工工件的内外 表面。相同的加工方法--使用不同形式的研磨 介质诸如粘接剂,粉状颗粒和磨粒--还包括研
