Rotary Joints For The Spindle Central Outlet CNC Machining Centers

If a CNC machining center is equipped with the spindle central outlet, then the rotary joint is a necessary spare part, without it, the CNC machining center can not work.

Now let's introduce the spindle central outlet first:

The spindle central outlet is an important component of the machining center, mainly used to cool and lubricate the cutting area during cutting, reduce tool temperature and wear, reduce adhesion and clamping phenomena on the machining surface, and improve machining quality and accuracy.

Advantages of spindle central outlet:

1. Eliminate the trouble of iron chips entangled with the tool and workpiece during metal processing, avoid iron chips entangled with parts and tools, and make cutting smoother;

2. Increase feed speed and cutting speed, increase cutting amount, and tap more productivity in production;

3. Reduce tool wear. In particular, the risk of tool breakage is greatly reduced. Reduce the local temperature generated by high temperature during processing and extend tool life;

4. Reduce the frequency of tool replacement, reduce the amount of tool used, reduce production costs, and increase the profit margin of products and parts;

5. The quality accuracy and universal interchangeability and stability of parts are greatly improved, reducing the generation of downgraded and scrapped parts;

6. Improve the surface finish of parts, the finish and roughness are more excellent and beautiful, improve the quality of parts, and improve the market competitiveness of products.

When machining deep hole materials, the spindle temperature will rise during the high-speed rotation of the machining center to complete the cutting process. As the speed increases, the temperature rises more obviously. The traditional cooling method is to pour cooling oil onto the workpiece surface. The cutting fluid can only take away the heat from the workpiece surface and the heat from the tool surface. It cannot cool down the workpiece, tool and spindle in the deep hole. In the worst case, it will cause the tool to break and the workpiece to be scrapped. In the worst case, it will cause serious thermal deformation of the spindle, seriously affecting the rotation accuracy of the spindle, and thus affecting the machining accuracy of the machining center.

The machining center is equipped with a high-precision spindle center water outlet device, and the corresponding spindle mechanical structure performance requirements are relatively high. Therefore, the spindle center water outlet device of the machining center mainly solves the problem that the traditional cooling method of the machining center cannot cool down the workpiece, tool and spindle in the deep hole.

Under what circumstances is it necessary to equip the spindle central outlet?

1. When the workpiece is processed with a harder material or the tool wears quickly, cooling and lubrication are generally required to ensure cutting quality and tool life;

2. When the workpiece has a large hole diameter or a deep depth, it is generally considered to flush the spindle central outlet to ensure the smoothness and verticality of the hole wall;

3. When the machining center performs high-speed machining, the heat generated in the contact area between the tool and the workpiece will increase rapidly, and the spindle center needs to be cooled and lubricated to ensure machining efficiency and quality;

4. Iron chips or debris may be generated during the machining process. The spindle centeral outlet can remove these chips to avoid affecting the cutting surface.

Although the spindle central outlet is very important in the machining center, it should be noted that not all workpieces or machining processes require the spindle central outlet. Therefore, when using the machining center, it should be judged and selected according to the actual machining situation. At the same time, when using the spindle central outlet, it is also necessary to pay attention to the quality of the water and the control of the water pressure to maximize its effect.
