As more and more mechanical equipment develops in the direction of high speed, high precision, high efficiency and high intelligence, the electric spindle has become one of the most suitable core functional components of high-performance numerical control machine. However, during the use of numerical control machine, the electro-spindle used high-speed rotary joints often fail, causing production to be suspended. The failure during the use of the electro-spindle rotary joint has seriously affected the production efficiency and should be paid attention to.

The electro-spindle rotary joint plays a very important role in the use of the electric spindle. Once a fault occurs, it will affect the operation of the entire CNC machine tool, thereby affecting the production quality and production efficiency. However, in the production process of many factories, the failure of the electro-spindle rotary joint will inevitably occur frequently.

Customers should pay attention to the following points when using the electro-spindle rotary joint, which can not only prolong the life and reduce the cost, but also reduce the trouble of product maintenance.

First of all, the correct selection is fundamental

It can only play its role if the correct model of the motorized spindle rotary joint is selected. Before using the electro-spindle rotary joint, the customer should confirm whether the application environment of the equipment exceeds the maximum allowable speed, maximum allowable pressure, and maximum allowable temperature of the specified model. If the limit of the rotary joint of the motorized spindle is exceeded, it will cause abnormal damage to the product. Dawei Ruisi Technology reminds the customer to check the range of the use parameters of the specified model before use, so as to avoid the situation that the working parameters do not meet the requirements.

Secondly, the beating of the shaft head is exquisite

The electro-spindle rotary joint is installed on the main shaft. Before installing the knife cylinder, test the deflection of the rotary joint. You can use a dial indicator to measure the tail of the joint, and the deflection within 0.05mm is normal. The runout requirement of the customer’s cooperation is within 0.005mm. Excessive runout of the spindle head will affect the stability of the rotary joint under high-speed operation. The follow-up sealing effect of the sealing surface will be affected, and the bearing will be worn at high speed.

Thirdly: plumbing connections are key

The supply hose and the leakage hose must not exert any additional force on the electro-spindle rotary joint itself. This requires that when the user uses the hose on site, the rigid hose cannot be directly connected to the swivel joint; a flexible hose should be used between the rigid supply pipe and the swivel joint, and the hose should not exceed the allowable bending radius. When the hose is excessively bent, the elbow can be used for transition. The leakage pipe should always face downwards. When installed vertically, the leakage hose should be at least 15 degrees downward. When installed horizontally, it should face the direction of 6 o’clock.

Dawei Ruisi Technology has always followed the pace of the market, always adhered to the concept of product quality and service, and continued to innovate and develop on the basis of introducing, digesting and absorbing foreign advanced technology. The design and production of the electro-spindle rotary joint are strictly controlled by technology.
