Note for use of motorized spindle
Motorized spindle is the basic guarantee of fine carving machining, its production accuracy is extremely high, such as the cone accuracy of the rotor end within 0.003mm. Because of its high accuracy, it has become the most vulnerable link in the use of fine carving machine! However, this does not mean that the service life of the fine carving machine spindle is low, in fact, as long as the operator strictly in accordance with the requirements of operation, the fine carving machine spindle or more durable. What should be paid attention to when using the fine carving machine? The following xiaobian take you to have a look:
1. The operator of fine carving machine must take up the post after strict training. Operators without training are strictly forbidden to use fine carving machine.
2. Open positive pressure seal must be ensured under the following conditions: during the operation of the motorized spindle, during the process of cutting fluid spraying, during the process of cleaning the machine tool or the motorized spindle, ensure that the gas connection pipeline is firmly connected and no leakage is allowed.
3. Before starting up and using, first ensure that the cooling circulation system of the motorized spindle works normally, and then turn on the motorized spindle. It is strictly forbidden to use the motorized spindle without cooling.
4. When using the cooling machine to forcibly refrigerate the motorized spindle, it must follow the operating instructions of the motorized spindle cooling machine.
5, spindle cooling use specific coolant, coolant must be clean, to timely supplement coolant, to ensure that the spindle cooling machine normal work, cooling line to keep open, so that the spindle can be normal cooling.
6, the use of precision carving machine must use a stable voltage power supply and uninterrupted power supply, in order to ensure the reliability of the work.
7, start work every day, the spindle should be in accordance with the principle of running from low speed to high speed, gradually rising speed preheating, when the spindle reached the required speed and no load running stable, stable temperature before processing. In this way, better machining accuracy can be guaranteed.
8. If the machine is shut down for more than two days, it must carry out no-load run-in for the motorized spindle according to the run-in steps of the motorized spindle from low speed to high speed, and can only be used after the run-in is passed.
9, in accordance with the principle of yifeng CNC technical service personnel with the knife to milling processing, in the planning of the knife road to ensure that the spindle force reasonable must avoid vertical knife, strictly prohibit the spindle overload work, to ensure the normal service life of the spindle.
10, strictly prohibit the use of knife blade wear tool processing, tool wear still continue to use, will increase the spindle axial force, resulting in bearing damage, but also affect the accuracy and effect of engraving.
