Learn what is a Ball Linear Way

Balls are used in the slider of the ball line rail of the CNC machining center, which has a small contact area and a small bearing capacity. The long-term use or long-term heavy-cut balls are easy to wear. Once it becomes an elliptical sphere, it basically cannot be finished. Need to get the rails replaced. But the ball is more accurate, if you buy it to process small parts of the mobile phone, the ball is better. At the same time, the ball linear rail moves faster and the processing efficiency is higher, but the gap is not particularly large.
