What are the main factors in the performance of the engraving machine?




Engraving machine is a kind of modern machinery and equipment widely used in advertising, woodworking decoration, stone, metal carving and other industries, bringing great convenience to the entrepreneurs' development. What factors determine the performance of the engraving machine?


It is mainly determined by the engraving speed, engraving intensity and spot size:


First, the engraving speed refers to the speed at which the laser head moves, usually expressed in IPS (inches per second), which results in high production efficiency. Speed ​​is also used to control the depth of the cut. For a particular laser intensity, the slower the speed, the greater the depth of the cut or engraving. You can adjust the speed with the engraver panel or with your computer's print driver. In the range of 1% to 100%, the adjustment range is 1%.


Second, the engraving strength refers to the intensity of the laser light incident on the surface of the material. For a particular engraving speed, the greater the intensity, the greater the depth of the cut or engraving. You can adjust the intensity with the engraver panel or with your computer's print driver. In the range of 1% to 100%, the adjustment range is 1%. The greater the intensity, the greater the speed. The depth of the cut is also deeper.

 

Third, the size of the beam of the engraving machine can be adjusted by using lenses with different focal lengths. Small spot lenses are used for high resolution engraving. Large spot lenses are used for lower resolution engraving, but for vector cutting, it is the best choice. The standard configuration for the new device is a 2.0 inch lens. Its spot size is in the middle and is suitable for all kinds of occasions.

Summary of the reasons for the broken machine in the engraving machine




First, the engraving materials and tools must match
Different carving materials are required for different engraving materials. For example, carving a stone with a knife that engraves wood, the carving material is too hard, but the tool is too soft, and the knife is strange! Therefore, you must express your use to the customer service before purchasing the tool. If there is any difference in the processing materials during the production process, please change the tool in time.


Second, the speed and depth of the engraving machine should be suitable
When processing hard materials, be sure to slow down, layer engraving, and lower the knife layer by layer, so as to avoid the tool from being unable to withstand the break.


Third, the tool is installed correctly, in place
Many customers do not fully understand the installation of the tool. When the tool is not installed, the engraving machine is started to work. If the tool is not vertical, it is easy to cause the knife to break.


Fourth, check the tool holder is clean
If the tool jaw is not clean, the tool will not be installed properly, and the tool installation will be inaccurate and not vertical. Especially woodworking engraving machines are more prone to such situations.


Fifth, the working conditions must be guaranteed
When the engraving machine is working, there should be no source around it. The power supply used by the engraving machine should keep the voltage stable. Good working conditions are the guarantee of effective work!

Carpenter engraving machine linear guide (square rail) strengths and defects



Any product has its own advantages and defects, today we will talk about the excellent defects of the linear guide of carpenter engraving machine. Carpenter engraving machine linear guides are as follows:
High positioning accuracy: application

Any product has its own advantages and defects, today we will talk about the excellent defects of the linear guide of carpenter engraving machine.
Carpenter engraving machine linear guides are as follows:


1. High positioning accuracy: When using linear slides as linear guides, because the friction method of linear slides is rolling friction, not only the friction coefficient drops to 1/50 of the sliding assist, but also the distance of the dynamic friction to the net friction changes. Very small. Therefore, when the bed is in operation, there is no slippage, and the positioning accuracy of the um level can be reached.

2. Low wear and tear can maintain accuracy for a long time: the traditional sliding guide, inevitably due to the oil film countercurrent effect, the channel movement accuracy is poor, and the sliding of the working track contact surface is insufficient due to insufficient sliding at the movement moment, which seriously affects the accuracy. The wear of the rolling guide is very small. Therefore, the Taiwan machine can maintain accuracy for a long time.

3. Use high-speed motion and drastically reduce the driving horsepower required for the machine: Because the friction of the linear slide is very small, the bed can be moved with less power, especially in the bed. When reciprocating, it is possible to significantly reduce the power loss of the machine. And because of the small heat generated by friction, it can be applied to high speed operation.

4. It can accept the load in the up, down, left and right direction: Because the special structure of the linear slide is designed, the load in the upper left and the right direction can be accepted together, and the lateral load that is acceptable in the direction of the parallel contact surface is not light. It is easy to form a machine with poor precision.

5. Assembling is simple and interchangeable: only need to mill or grind the mounting surface of the slide rail on the bed, and follow the proposition to slide the slide rail and the slider to the machine with a specific torque. Reproduce the alarm density during processing. The linear slides are interchangeable, so you can get the precision from the replacement slider or the slide rail or even the linear slide group.

Carpenter engraving machine linear guide defects are as follows:

1. Static friction is larger than the coefficient of the compass, and it is easy to crawl at low speed (1-60mmmin).

2. When using for a long time, if the machine tool is slightly deformed, the working speed will be lowered, which directly affects the production capacity.

3. Equal motor uses the lower gauge to drive the motor nm to add a certain load.

4. The guide rail attachment surface is required to have high precision and large cost.
5. Appearance is easy to rust

Woodworking engraving machine milling cutter selection and cutting skills



The CNC Carpenter Carving Machine can be used for embossing, and can also be used for cutting, punching, engraving and so on. In different applications, the processing methods are different, such as different spindle speeds, different tools, etc. Jinan carpenter carving machine manufacturers use the carpenter carving machine to cut the board as an example.

    1. The use of carpenter carving machine is the first choice of the tool, according to the nature and requirements of the cutting target, from the two aspects of skills and economy, consider the selection of all milling cutters, welding all milling cutters, installing milling cutters and combination milling cutters.

    2. After selecting a good tool, the most important thing is to control the cutting speed and dosage. The cutting amount of the milling cutter 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 surface to be machined. The roughness of the workpiece to be cut depends largely on the feed per tooth of the milling cutter. The feed per tooth is too large, the machining appearance is too rough, the feed per tooth is too small, and the machining appearance will be burnt. The focus phenomenon, so the feed per tooth of the milling cutter must be appropriate.

    The above two points can be correctly achieved. By selecting the milling cutter and controlling the cutting amount, the workpiece can be well processed, and the roughness of the workpiece surface is reduced, and the accuracy of several dimensions and shape orientation is improved.

How to choose a good woodworking machine



Buying a woodworking engraving machine is a top priority

First, pay attention to the spindle motor of the engraving machine. The spindle motor is an important component of the computer engraving machine, and its performance has a crucial influence on the performance of the computer engraving machine. Machining spindles are generally divided into two categories: precision machining spindles and high power cutting spindles. Fourth, pay attention to its guide rails. The large-format engraving machine must use a widened imported square guide rail, which has more than 30 times the load capacity and precision retention capability of the circular guide rail, ensuring the high quality and high speed of the engraving machine.

1. The characteristics of the fine machining spindle are low noise, high speed and height, suitable for processing particularly fine workpieces such as stamps, nameplates, badges and so on. Such motors are usually high-speed variable frequency motors with low power, typically below 250W. The disadvantage is that the ability to cut thick materials is poor and does not cut off thicker materials.

2, high power cut off the spindle, mainly used for cutting, high power engraving, characterized by high power, strong cutting ability, especially suitable for cutting the universe, three-dimensional characters, of course, you can also make badges, nameplates, seals and so on. Such high-power spindles can be generally divided into brushless high-speed AC motors and brushed AC motors according to the characteristics of the motor. The main difference is: A, the brushless inverter motor has a high speed, and the shift range is 70060000 rpm, and generally there are The maximum speed of the brush AC motor does not exceed 24000 rpm: B. The brushless variable frequency motor has high rotation precision, low wear and low noise, and the noise is much lower than that of the brushed AC motor; C, the brushless inverter motor has good blocking characteristics, due to There is a special current limiting circuit on the inverter. The short-time blocking will not burn the motor, and the brushed AC will burn out quickly when it is overloaded or blocked, and it cannot be repaired. D. Brushless inverter motor It adopts frequency conversion control technology to adjust the speed. It is a professional-grade product with long service life. The manufacturer provides one-year free replacement. In the future, the motor can be maintained by replacing the high-speed bearing. The brushed AC motor has a life of about 300 hours. The motor or motor carbon brush has to be replaced, so the carbon brush AC motor is usually not guaranteed for one day.

Second, the selection of the control mode and speed of the engraving machine: the control mode can now be divided into three types:

1, using the control of the single-chip computer, this controller can be typeset while the engraving machine works, but can not turn off the computer, which is actually equivalent to saving 7 computers, and reducing the waste caused by the computer's misoperation.

2, using the USB port to transfer data, the system has a memory capacity of more than 32M. As long as you save the file, you can completely disconnect from the computer, turn off the computer, or perform other typesetting. This method greatly improves the working efficiency of the engraving machine.

3. All the calculation work is completed by computer control. When the engraving machine is working, the computer is in working state, and other typesetting work cannot be performed. This may cause the computer to malfunction and cause waste.

Third, look at the size of the engraving machine. The customer should select the model of the engraving machine and its power according to the needs of the business and the funding situation. Generally, the small-format engraving machine has 600mm×600mm and 600mm×900mm, and the feeding width is 700mm. The engraving two-color board is the most basic application of the small-format engraving machine, and the acceptance is very good. The price of the smaller engraving machine is similar to that of the engraving machine, but it is more troublesome and unnecessary waste when engraving the two-color board. The large-format engraving machine has 1200mm×1200mm, 200mm×1500mm, 1500mm×2400mm, 2400mm×3000mm. The engraving machine of the above models has a width of more than 1350mm. Now the size of plexiglass and PVC board on the market is 1300mm× 2400mm, so these models are suitable for customers who require large-format engraving machines.

Fourth, the accuracy of the engraving machine, small-format machine engraving 1mm Chinese characters, or large-format engraving machine engraving 1.5mm small characters, must be seen very clearly under the magnifying glass.
