機床鑄件熱處理過程：

床身類鑄件產品作為一種大型鑄件必須要經過熱處理才能提高本身的使用性能，改善鑄鐵鑄件的內在質量。金屬熱處理是機械制造中的重要工藝之一，與其它加工工藝相比，熱處理一般不改變工件的形狀和整體的化學成分，而是通過改變工件內部的顯微組織，或改變工件表面的化學成分，賦予或改善工件的使用性能。其特點是改善工件的內在質量。

As the large castins, lathe bed castings must be subjected to heat treatment in order to improve the performance itself, and  improve the intrinsic quality of iron castings. Usually the heat treatment does not change the overall shape and chemical composition of the workpiece, but by changing the microstructure within the workpiece, or to alter the chemical composition of the workpiece surface to improve the performance of the work piece. Its characteristic is to improve the intrinsic quality of the workpiece.
