Cutting oil
detail
This product is made of refined mineral oil, sulfide ester oil, antioxidant and antirust agent. This product is suitable for high load, low speed metal cutting operations, such as gear shaping, gear hobbing, etc. Processes and small section operations, such as gear milling, thread cutting and other processes, mainly play the role of lubrication and cooling.

2、 Characteristics
1. This product has low viscosity, good cooling performance and washing performance;
2. When the friction surface is in boundary lubrication under high temperature and high pressure, the sulfur in the oil can react with the metal surface to form a thin layer of metal compound with low shear strength, so as to prevent metal sintering, keep the friction surface lubricated, and improve the surface finish of the machined surface.
3. High flash point, good viscosity temperature index, not easy to produce smoke.
3、 Precautions
1. In the process of storage and use, keep the oil clean, avoid water mixing, and do not mix with other oil in use.
2. Keep sedimentation and filtration equipment in good condition to filter out impurities at any time.
