Woodworking engraving machine processing path optimization and setting method

?? During the use of woodworking engraving machine, we often need to optimize the engraving path, so that we can achieve better engraving effect slowly. The following is a simple sharing of engraving settings.

?? In the engraving software, the user can edit and modify the generated 2D path. When editing, first select the path graphic we need to edit, and then click “Engraving Path Edit” under “Path Calculation”, the toolbar of the engraving path editing will appear, and the path to be edited will be selected. Can be used), edit and modify.

The first item of the toolbar is to define the starting point, and the starting point of the engraving can be arbitrarily specified in the engraving path; the second item is the reverse order, that is, the selected path is changed to the opposite direction; the third item is disconnected, utilizing This function can increase the position of the ribs arbitrarily; the fourth item is sorting, which can sort the selected paths in order; the last item is saved, but we must not forget to save after we modify it. After the woodworking engraving machine, you should first simulate the preview to avoid errors.

?? How to set the engraving start position of the engraving machine, the starting position is mostly set in the lower left corner or the center, manually move the knife to the required starting point to set the program path of the CNC engraving machine.

?? First set the starting point, you can define any point in the engraving path of the CNC engraving machine as the starting point of the engraving path to change the position of the falling point during machining. We can adjust the starting position according to the requirements of the machining process. The second is to set the path reversal, and change the engraving path of the selected CNC engraving machine to the opposite direction, so that the machining direction is consistent with the texture of the processed material. Make the processing effect more perfect. Once again, design the arc fit. For tool paths and machining calculations, the results obtained using the arc curve are better than the short fold lines. It can significantly reduce toolpaths, save machining time, and make the machined curve smoother.

Finally, the ribs are set: the ribs are set to avoid the damage or processing error of the machined parts caused by the movement of the object before the end of the machining, and the workpieces are not completely disconnected. Manually separate them after the end. We can make the material reinforcement in the position where there is no processing requirement.

How to repair the woodworking machine motor How to do the engraving machine motor is broken

It is quite common for woodworking engraving machines to have component damage in production equipment with very high workload. However, even in the case of component damage, the first thing we need to do is to determine the damage, and then try to repair it by ourselves. It is normal for the motor to be in disrepair for the power source of the whole engraving machine. Today, Xiaobian brings you a solution if the engraving machine motor appears. Next, follow the CNC network Xiaobian to learn how to repair the woodworking machine motor, how to do the engraving machine motor is broken!
1. Engraving machine removes front and rear end caps, front and rear nuts.
2. Push out the spindle and rear bearing housing, linear bearing and other accessories from the front end of the shaft.
3. Research the bearing washers before and after.
1. The front and rear bearings of the electric spindle are connected in series with DT.
2. According to the direction of the axial force of the bearing, support the inner sleeve and press the sleeve downwards with your hand. (The size of the force is almost the same as the preload of the spring to the bearing). Adjust the gap of the washer. There are two ways. First, replace the upper and lower positions of the bearing and the bearing, and secondly, the height of the grinding washer. The grinding washer is grounded by 8 characters, and the position of the washer is rotated to ensure that the parallel difference of the washer is within 2 um. The inner and outer washers are adjusted by adjusting the gap of the washer. Even if the force is even, the preload of the two sets of bearings is even.
3. If the matched bearing is used, the difference between the inner and outer washers is less than 2um, the parallel difference of the washer is within 2um, and the bearing is matched by the V-shaped mark on the outer diameter.
4. The pre-tightening spring will cause fatigue and reduce the elastic force for a long time; the preload of the bearing is reduced, which affects the accuracy and life of the electric spindle. At this time, the new spring of the same specification should be replaced.
5. If the gasket is not suitable for the research, if the load of one set of bearings is small and the load of the other set is too large, the bearing will be unevenly loaded and will generate heat, which will seriously affect the service life. When the inner and outer washers are under the same force, then two sets The bearing is subjected to a uniform preload load.
4. Clean the bearing, the casing slope down (or the inner sleeve slope upwards) to rotate and clean (in clean gasoline), the bearing should be cleaned more than twice, pay attention to cleaning the bearing, the bearing up and down position can not be misplaced.
5. Before loading the bearing, the bearing and the inner hole of the shaft shell and the main shaft are first lubricated with oil (special lubricating oil for electric spindle). One is convenient for installation, and the other is to ensure the lubrication of the initial bearing of the electric spindle.
6. Clean other parts on the shaft. The bearings should be dried naturally after cleaning. Do not blow dry with high pressure gas.
7. First install the rear end bearing, the nut is tightened, the spring is fixed on the bearing seat with butter, and the spring gland cannot be misplaced.
8. Assemble the front end bearing and fix the front end cover to pre-press the bearing outer casing. (The special bearing sleeve should be used for assembling the bearing. The sleeve is machined with nylon rod. The shape is as follows: D is smaller than the outer diameter of the bearing, d is larger than the inner diameter of the bearing).
9. Tighten the front nut, install the front and rear end caps, and pay attention to the position of the air intake hole when installing the rear end cover. The sealing ring of the air inlet hole, the water inlet hole and the water outlet hole should be intact and placed in the correct position.
10. After the front and rear bearings are installed, push the spindle forward from the rear end of the electric spindle, and the linear bearings are pushed into position at the same time.
11. After the motorized spindle is installed, check if the spindle is installed in place (use the wrench to push the spindle forward, the spindle will move forward, and the hand will bounce back immediately.

Finishing woodworking engraving machine tool wear, purchase method and extending service life

After the use of woodworking engraving machines, some customers reflect the wear of the tools during the use of the tool. Then how to reduce the tool wear of woodworking engraving machine and increase the service life of the tool. In addition to solving these problems, we also helped you to sort out the precautions for purchasing woodworking engraving machine tools.
 First, woodworking engraving machine tool wear
The main reasons that affect the tool wear of woodworking machine are as follows:
1, cutting amount: including spindle speed, feed rate, path spacing, knife depth and other parameters.
2, tool type tool data: select the appropriate tool for the machining depth and its angle, material
3. Direction of the cutter: The design of the engraving program must be related to the use of the cutter.
4, the knife way: according to the material must choose the appropriate knife direction.
5. Cutting fluid: The method of auxiliary engraving must be appropriate.
Second, woodworking engraving machine tool wear judgment
1, according to the movement state of the engraving machine in the process to determine the wear condition of the tool, such as processing parameters, cutting amount and other settings are reasonable, the engraving machine in the processing vibration is very large, and a "beep" sound, you can be sure The tool has reached a state of rapid wear and must be changed immediately.
2, woodworking engraving machine tool wear, the amount of wear, the most important and most direct way to distinguish is to "listen" sound, if the cutting sound is very "heavy" or issued a "screaming and harsh" sound, indicating the processing status of the tool If it is not normal, the machining can be stopped at this time. If the tool quality problem, the tool clamping problem, and the tool parameter problem are removed, it can be proved that the tool is worn out, so it is necessary to suspend the machining and change the tool.
Third, extend the life of woodworking machine tool
In the work of woodworking engraving machine, tool wear and broken knife are inevitable, how to extend the service life of the tool! Changsha Xinye CNC Equipment Manufacturing Co., Ltd. summarized the following points:
1. Choose the right tool: For the high hardness material, use the corresponding tool, otherwise it is easy to break the knife.
2, the maintenance of the tool: the processing must be properly kept in the tool, ready for the next use of the tool. When employees get off work, be sure to separate the tools and materials.
3. During the engraving process, the tool broken inside the material should be taken out in time, because when we re-engraving, it is not necessary for the engraving knife to hit the short knife and break again.
4. Engraving speed: When carving high hardness materials, do not cut the knife too fast.
Fourth, choose woodworking engraving machine tool precautions
1. Choose according to tool complexity, manufacturing and sharpening cost: the tool life of complex and high precision should be higher than that of single-edged tool. For multi-knife engraving machines, combination engraving machines and automatic machining tools with complicated tools, tool changes and tool adjustments, the tool life should be selected higher, especially for tool reliability.
2. When the productivity of a certain process in the workshop obviously limits the productivity of the whole workshop, the tool life of the process should be selected lower; when the total expenditure of the whole plant is shared in a certain process, the tool The life expectancy should also be chosen lower.
3. In the case of large-scale finishing, in order to ensure that at least one pass is completed and the tool is changed midway during cutting, the tool life should be determined according to the accuracy of the part and the surface roughness.
