As you know, hard materials such as stainless steel is not easy to be cut with ordinary saw blade, and it is common to use HSS saw blade for cutting. At the same time, there is high requirement on cutting fluid and its cooling ways. Here are a few cutting fluids introduced to you and you can choose the right ones according to your different conditions.

Firstly, mineral oils such as engine oil and spindle oil. Such oils have good performance of unctuosity, however, its cooling effect and permeability is very poor, because of such feature, it is suitable for outer round finish turning.

Secondly, vegetable oil such as soya-bean oil and rapeseed oil. Because of its good performance of unctuosity, it is better to used on screw thread, reaming, tapping and other working procedures.

Thirdly, emulsified liquid. As you know, emulsified liquid not only has good performance of cooling function and cleaning effect, but also has good lubrication function. Therefore it can be used on stainless steel rough turning. Meanwhile, during cutting process, you can use it to cool cutting temperature and it is better to use high pressure cooling way and atomizing cooling way.
