What is the cooling liquid for shaving double-wheel bevel gears?

The cooling liquid used for bevel gear shaving of double gears is emulsified cutting fluid and fully synthetic stainless steel cutting fluid, which can overcome the problem of insufficient cooling during high-speed cutting, improve machining quality and reduce tool wear. However, for the original hobbing and slotting machine tools, measures must be taken to prevent water from entering the rotating parts to avoid machine tool failure.
