What is the damage to the advertising engraving machine spindle?
1. The quality problem of the engraving machine spindle.
That is to say, the quality of the spindle itself is not enough to cause damage to the bearing. The bearing of poor quality is used, and the life is shortened when the spindle of the engraving machine is running at a high speed, and it is easy to be easily damaged.
2. The engraving spindle cooling system has no effect.
The water circulating system of the engraving machine has a water circulation system. If the long-term water circulation is not good, or the water circulation is forgotten, the heat rise effect will occur when the time is long, resulting in increased friction and damage to the bearing.
3. It is related to the specific operation of the engraving machine.
Some spindles start to engrave when they have not reached the speed, which is easy to cause damage to the bearings. Some customers have different resistances of engraving materials when engraving, and do not adjust the speed in time, and finally damage the engraving machine spindle.
4. The water-cooled spindle is not well protected against freezing.
It is important to pay attention to this in the winter. It is not uncommon for water to freeze in the cold winter, and the spindle of the engraving machine will be frostbitten.
What should I pay attention to when the advertising engraving machine spindle is damaged? The spindle is protected against freezing; the water circulation cooling device is regularly checked.
Advertising engraving machine spindle safety precautions?
The bearings must be cleaned before installation because the bearings are protected from rust and rust-preventing oil between the raceways and the rolling elements before leaving the factory. Therefore, it must be cleaned with clean gasoline and kerosene, and then coated with a clean high-quality or high-speed high-temperature lubricant. However, some fully enclosed bearings and spindle bearings coated with lubricated rust-proof grease do not require cleaning. The effect of cleanliness on bearing life and vibration noise is very large.
1. Special positioning of high-speed and high-precision spindle bearings: In some special cases, when the shaft shoulder and rounded corner dimensions cannot be determined according to the installation dimensions listed in this catalog, transition gaskets can be used as axial supports.
2, high-speed, high-precision spindle bearing spring retaining ring positioning: bearing is not subject to axial load, high speed, short wheelbase and difficult to machine the thread on the journal, the flexibility of the section can be used Positioning of the retaining ring. This method is convenient for loading and unloading, has a small position and is simple to manufacture.
3, high-speed, high-precision spindle bearing thrust washer positioning: in the shorter journal, the shaft is difficult to machine into a thread, the spindle bearing speed is higher, the axial load is larger, the gasket can be positioned, that is, The washer is positioned with more than two screws on the end face of the shaft and is screwed with a retaining washer or wire to prevent loosening.
When the inner ring is mounted on a high-speed, high-precision spindle bearing, the bearing is generally fixed to the bearing on one side, and the other side is fixed by a nut, a retaining washer or a spring retaining ring. The dimensions of the shoulder and axial fixed parts and the inner ring of the bearing can be determined according to the mounting dimensions of the various types of bearings listed in the bearing size table.
