In the working process of cnc vertical Machining Center V1165, the tool will produce high temperature and high heat when cutting the workpiece. In order to reduce the cutting temperature of the tool, the water outlet function of the spindle of the machining center usually uses cutting fluid to cool the tool. However, the high-speed rotation during cutting and the transpiration of the liquid can easily cause the cutting fluid water vapor to enter the spindle unit structure of the machining center and damage the bearings inside the spindle of the machining center. As a result, the service life of the spindle of the machining center is shortened. If it happens in the entire processing process, it will easily cause injury accidents.
Let's first understand the structural design of the spindle unit
1. Axle
2. Front end cover
3. Shaft seat
4. Electric bearings
5. The first lock nut 6. Through hole
7. Disc spring
8, 7012C bearing
9. Dust cover
10. The first arc toothed belt wheel
11. The second lock nut
12. The second arc toothed belt wheel
13. Nut
14. The third lock nut
15. Rear cover
16. Ejector
17, the first spacer
18. The second spacer
19, four-petal claw
20. Bolt
In order to prevent the problem of water ingress into the main shaft unit of the machining center, the two sections of the main shaft can adopt a variety of complex sealing structures. Regardless of whether the main shaft is stationary or the cutting motion, the cutting fluid can be effectively prevented from entering, thereby ensuring the inside of the main shaft. The service life of the parts. There is a drain hole on the front end cover of the spindle, and the drain hole should face down when installing horizontally. The front flange of the product is designed with an air curtain protection interface. When we use it, we will connect the compressed air after drying and filtering, which can effectively prevent the intrusion of water vapor or dust. When the air curtain is not used to protect the interface, please do not unscrew the screw.
