Rolling machine - Atsuenki

Japanese: 圧延機 - あつえんき

A machine that processes metal or precious metal sheets into sheet material by sandwiching them between a roll and a flat plate, or between two rolls, and passing them through the rotation of the rolls to flatten and roll them. Rolling mills for processing steel appeared by the 18th century. The use of roll machines for rolling soft metals such as gold, silver, and lead dates back even further to Leonardo da Vinci. Many of today's rolling mills are mass-produced continuous production machines such as strip mills, and large blooming mills, in which the process from raw material to finished product is automatically controlled. Depending on the number of rolls, rolling mills are divided into 2-4 stage types with 2-4 rolls, and multi-stage types with more than 4 rolls, and there are also planetary types in which many small diameter rolls are arranged around a large diameter roll.

金属，貴金属の板をロールと平板の間，またはロール同士の間に挟み，ロールの回転により通過させて展伸・圧延を行い板材に加工する機械。鉄鋼加工用の圧延機は18世紀までに出現。金・銀・鉛など軟質金属圧延のロール機使用はさらにレオナルド・ダ・ビンチにさかのぼる。今日の圧延機は，ストリップミルのような大量連続生産機，大型の分塊圧延機など，素材から製品までの工程が自動制御されるものが多い。圧延機はロールの本数により２〜４本の２〜４段式，それ以上の多段式に分け，また多数の小径ロールを大径ロールのまわりに配置した遊星式などもある。
