What is a lathe?

ü     What is a lathe? (車床是什麼?) 

      Lathe, also known as rotary lathe, is an electric drive motor that rotates the spindle through belts and gears, and drives the workpiece on the spindle chuck to rotate. The lathe is then turned using a turning tool fixed on the tool holder.

      In 1797 the British Henry Mosley invented the lathe, which is usually used for machining cylindrical workpieces. The lathe is not only the earliest invention in the workbench, but it is also one of the most widely used machine tools in machining. It is called "the mother of machine tools."

      General lathe is equipped with all kinds of special tools, the main processing workpiece is a round bar, the cutting work has car face, inside and outside diameter, arc, taper, drilling, boring, eccentric, embossing, cutting, grooving, car screw.

1.  Lateral feed: The direction facing the lathe, the vertical bed rail or the center line of the main shaft is called horizontal (as across the river), so the turning of the turning tool in this direction is called horizontal feed.

2.  Longitudinal feed: facing the lathe, the direction of the parallel bed rail or the centerline of the spindle is called the longitudinal direction, so turning the lathe to do the turning work in this direction is called longitudinal feed.

     車床（Lathe），又稱鏇床，是由電力驅動馬達，經皮帶及齒輪等傳動系統使主軸轉動，帶動主軸夾頭上之工件旋轉，再利用固定於刀架上之車刀進行車削之工具機。

     1797年英國人亨利·莫茲利發明了車床，通常用在圓柱型態的工件加工。車床不但是工作母機中發明最早，且為機械加工中最廣泛使用之一種工具機，有「工具機之母」之稱。

     一般車床配備各種專用刀具，主要加工工件為圓型桿件，切削工作有車端面、內外直徑、圓弧、錐度、鑽孔、搪孔、偏心、壓花、切斷、切槽、車螺。

1.  橫向進刀：面對車床，垂直床軌或主軸中心線之方向，稱為橫向（如橫越河流一般），故車刀於此方向做車削工作，稱為橫向進刀。

2.  縱向進刀：面對車床，平行床軌或主軸中心線之方向，稱為縱向，故車刀順此方向做車削工作，稱為縱向進刀。
