Cylindrical grinding - Endo Kensaku

Japanese: 円筒研削 - えんとうけんさく

...In addition to these characteristics, the abrasive grains themselves are very hard and the cutting depth is very small, so even high-hardness materials that cannot be machined by turning can be quickly finished with high precision and quality.
[Working method]
Grinding processes can be broadly classified into cylindrical grinding, surface grinding, internal grinding, centerless grinding, and others based on the method used. Cylindrical grinding is a method in which a cylindrical workpiece is ground by rotating it in contact with a cylindrical grinding wheel while moving it axially. …

From [Machine Tools]

...In this case, the machining style in which the milling cutter is replaced with a grinding wheel is called surface grinding. e is a machining style in which the tool, the grinding wheel, performs a rotary cutting motion and the workpiece performs a rotary and linear feed motion, called cylindrical grinding, and is used for precision machining. In grinding the inner surface of a hole (internal grinding), the grinding wheel often performs a rotary cutting motion and a linear feed motion, and the workpiece often performs a rotary feed motion. ...

Japanese:

…この特性とあわせて，砥粒自体が非常に硬く，また切込量が微少であるため，旋削で加工できないような高硬度材料でも迅速に高精度，高品質に仕上加工をすることができる。
［作業方式］
　研削加工をその作業方式で分類すると，円筒研削，平面研削，内面研削，心なし研削とその他に大別される。円筒研削は，円筒形工作物を円筒形といしと接触回転させながら軸方向に移動させて工作物の外周面を研削する方法である。…

【工作機械】より

…この場合，フライスをといし車に置き換えた加工様式が平面研削加工である。eは，工具であるといし車に回転切削運動，工作物に回転および直線送り運動を行わせる加工様式で，円筒研削加工と呼ばれ，精密な加工をするのに用いられる。穴の内面の研削加工(内面研削加工)では，といし車が回転切削運動と直線送り運動，工作物が回転送り運動をすることが多い。…
