Where do lathes and millers get tired?

Threading is the most tiring job for lathes, because it will be tiring for the waist and neck to always maintain the same posture. After get off work, you should move your waist and neck and massage your knees and feet to avoid joint diseases. The main thing is to transport the materials for your own use. The main source of dirt is lubricating oil and sludge, but if you pay attention to cleaning and maintaining your own equipment, it won't be a big problem. There will be some dust when sharpening the knife, so it is best to wear a mask. After sharpening the knife, blow it with compressed air or dust it clean before taking off the mask.
