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.

Advertising engraving machine tool selection factor?

1. Material factors (PVC and plexiglass)

For the cutting of PVC or plexiglass with a thickness of 5mm or less, a single-edged thread milling cutter is used. This tool has good chip removal effect and sharp edge, but the strength is poor, so it is used to cut soft PVC material. When cutting plexiglass of 10mm or more thickness, use a double-edged thread milling cutter.

2, material thickness factors

Choose tools with different blade lengths for materials of different thicknesses. Now the thickness of the material on the market is relatively fixed. For the market demand, the company has provided the cutter with the corresponding blade length. The blade lengths are: 22mm, 17mm, 12mm, 7mm, 4mm and so on. The choice of the tool should follow the principle that the blade length of the machining tool is slightly longer than the material by about 2 mm.

3, the size of the text factor

For different sizes of text, we choose the tool diameter is different, the optional knife has a diameter of Ф4mm, Ф3.175mm, Ф1.5mm, etc., under the premise that the inner R angle can meet the requirements, try to use the larger diameter tool .

4, tool loading

When the tool is loaded, the distance from the tip to the chuck is as short as possible. Under the premise that the blade is exposed, the excess part does not exceed 2 mm. If the tool is loaded longer, the cutting speed must be reduced.

When using a new tool, the cutting speed is cut at 50% of the normal speed, that is, 0.3 m/min. After the operation is smooth, it is gradually adjusted to the normal speed, that is, 0.6 m/min.

Teach you a few strokes to easily deal with the failure of the advertising engraving machine

First check the engraving machine spindle motor. If the motor is hot, look at the pump work for any abnormalities, and then look at the water inside the fuselage is not lower than the liquid level. If it is true, it will be the right medicine.

Then if the speed of the motor is slow or does not turn at all, we have to check the line. We must check the motor line and cable separately to see if there is a short circuit or no power. If this is the case, we must rebuild the circuit. , return to normal operation.

There is also the motor running in the opposite direction, it is necessary to check whether there is any problem with the motor line and whether the uvw port of the output data is exchanged. If the port position is wrong, it should be adjusted in time.

Finally, the motor of the advertising engraving machine has a strange sound. At this time, it depends on whether the motor is overloaded. If it is because of the load, stop the machine in time, and wait for the machine to rest for a while.

What should I pay attention to when using a stone engraving machine?

 There are many factors in the speed of engraving. The first thing that can't be set is the configuration of the machine itself, the power of the finishing. There is also the skillful mastery of the technology, the choice of the tool, the material of the stone, etc.
    With the wide application of stone engraving machines, more and more customers who are just beginning to understand the CNC stone engraving machine often ask: "How about the speed of engraving, how long does it take to engrave a square?"
    There are many factors in the speed of engraving. The first thing that can't be set is the configuration of the machine itself, the power of the finishing. There is also the skillful mastery of the technology, the choice of the tool, the material of the stone, etc.
    1. Theoretical basis: The training work must start from the theoretical training work, and the operators must conduct practical operation training under the condition that the theoretical assessment is passed. If the theoretical training is not passed, it is absolutely impossible to conduct operational training.
    2, the use of stone engraving machine tools: After the theoretical training, the tool training must be carried out. Operators must be aware of common tools, engraving motor speeds, travel speeds, precautions, etc. Operators must be familiar with the application of the tool.
    3, the scope of application of stone: operators must be familiar with the application range of various materials, familiar with different materials, different thicknesses, different finished products and so on. Familiar with different engraving methods for different materials.
    4. Operation of various software of stone engraving machine: After the above training, software training can be carried out. Software training is mainly concentrated in the field of user applications; software requirements are: various types of software layout, various operations, path generation, and the ability to quickly find path errors.
    1. The continuous running time is less than 10 hours per day to ensure the cleaning of the cooling water and the normal operation of the pump. The water spindle motor must not be dehydrated, and the cooling water should be replaced regularly to prevent the water temperature from being too high. In winter, if the working environment temperature is too low, the water in the water tank can be replaced with antifreeze.
    Second, each time the machine is used, it is necessary to pay attention to cleaning. It is necessary to clean the dust on the platform and the transmission system, and regularly and weekly (weekly) lubricate the transmission system (X, Y, Z three axes). (Note: X, Y, Z three-axis polished rods are maintained with engine oil; screw parts are added with high-speed butter; in winter, if the working environment is fully automatic, the temperature of the computer engraving machine is too low, and the lead rods, polished rods (square rails or circular guides) should be Flush and clean with gasoline, then add the oil, otherwise the resistance of the machine transmission will be too large and the machine will be misaligned.)
    Third, protect the electrical appliances
    The inspection is to cut off the power supply. After the monitor has no display and the main circuit power indicator is off, the computer wood engraving machine can be carried out.

Woodworking engraving machine milling cutter selection

1. Determine the main technical parameters of the milling cutter, such as tool outer diameter, machining thickness, and central aperture. In addition, the number of cutter teeth, the direction of rotation, the speed of rotation, the feed speed, the clamping method, and the material of the cutter are also specified.

2. Select the structural form of the milling cutter. According to the nature and requirements of the cutting object, the overall milling cutter, the welding integrated cutter, the assembly milling cutter and the combined milling cutter can be selected from the technical and economic aspects.

3. Select the direction of rotation of the milling cutter. The direction of rotation of the milling cutter is determined according to the direction of rotation of the machining spindle and the relative position of the cutter shaft and the feed workpiece. Whether it is an integral milling cutter or an assembly milling cutter, the inclination of the cutting edge relative to the radius of the milling cutter determines the rotation of the milling cutter. direction.

4. Select the cutting amount of the milling cutter. The cutting amount of the woodworking engraving machine includes the cutting speed of the milling cutter, the feed rate of the workpiece and the milling depth. The cutting speed of the milling cutter depends on the milling cutter speed and the radius of the milling cutter. The feed rate of the workpiece depends on the quality of the machined surface. The surface roughness of the workpiece to be cut depends largely on the feed per tooth of the milling cutter during the cutting process. The feed per tooth is too large, the machining surface is too rough, the feed per tooth is too small, and the machined surface will burn. The focus phenomenon, so the feed per tooth of the milling cutter must be appropriate.

The milling cutter is an important part of the woodworking engraving machine. It is a rotary cutter with one or more cutter teeth. During operation, each cutter can intermittently cut off the remaining amount of the workpiece. The quality of the milling cutter will directly affect the engraving effect of the woodworking engraving machine, so we should make more efforts in the selection of the milling cutter.

How to maintain the stone engraving machine in winter

 The weather is getting colder and colder and it has entered the winter. A lot of work in the winter requires special protection to work properly. Stone engraving machine is one of them, then how to maintain the stone engraving machine in winter! Today, Jinan Zhongke will introduce you how to carry out the maintenance of the stone engraving machine in winter.

  The stone engraving machine's unique water cooling system, while optimizing the performance of the stone engraving machine, is also bound to its own limitations. Generally, the temperature suitable for engraving is between 0 and 45 degrees. When the temperature is lower than 0 degrees Celsius, the tap water used for cooling will freeze, which will inevitably affect the use of the engraving machine. Moreover, the relative humidity of the stone engraving machine ranges from 30% to 75%. The environment that is too dry and too humid is not conducive to the optimal control of the engraving machine and the power system. The relatively dry environment in winter is also not conducive to the normal use of the engraving machine.
Therefore, in winter, attention should be paid to the warmth of the engraving machine. The residual water in the water pipe should be removed in time to avoid the water circulation after the next day's freezing; the pump should be taken out from the water tank or bucket in time to avoid freezing inside; Secondly, pay attention to the maintenance of dry humidity in the plant. If it is too dry, you can increase the number of mopping the floor and maintain the proper humidity of the plant. It is recommended that the machine not be placed outdoors during the winter, it is best to move the machine to the factory.
