2、 What are the advantages of the ball three wire rail of the CNC gantry milling machine
The slider of the ball track of the CNC gantry milling machine uses round balls, which have small contact area and bearing capacity. The balls are easy to wear after long-term use or long-term re cutting. Once they become oval balls, they can't be finished. They must be replaced. But the precision of the ball is higher. If you buy it to process small parts of mobile phones or glass carvings, the ball is better. At the same time, the ball track moves faster and the machining efficiency is higher, but the gap is not particularly large
There are many advantages in the structure of the ball three wire rail of the CNC gantry milling machine. This is the mainstream wire rail structure of the CNC gantry milling machine at present. The proportion of hard rail machines in the market is still relatively small. The CNC gantry milling machine with ball three wire rail structure has the following advantages.
1. Fast displacement and high machining efficiency
2. Better machining accuracy of ball track
3. Better machining finish of ball track
The wire rail is a rolling friction, point or line contact, with small contact surface and small friction. It is mainly used in high-speed machining and mold industry. For machining with small cutting volume and fast tool walking, in a word, roller track is very fast. At present, high-speed CNC gantry milling machines and high-speed drilling and tapping centers all use the structure of ball track. If you need CNC gantry milling machines, please contact us.
