What is the similarity and difference between CNC engraving and milling machine and CNC engraving machine?

     

       The engraving and milling machine is a kind of CNC machine tool. It is a CNC machine tool that corresponds to a traditional engraving machine. They believe that the engraving and milling machine is a CNC milling machine for small tools, high-power, high-speed spindle motors. The advantage of the engraving machine is engraving. If the hardness of the machined material is relatively large, it will be difficult. The appearance of the engraving and milling machine can be said to fill the gap between the two. The engraving and milling machine can be engraved and milled. It is a high-efficiency, high-precision CNC machine tool. Sharp is an outstanding generation of engraving and milling machines and CNC engraving machines.




      Small CNC engraving machine: suitable for small high-speed spindle machining tools, the torque is relatively small, focusing on the engraving function, such as wood (wood processing, especially wood carving machine) board and two-color board, the hardness of the acrylic board is not high, the workpiece is not suitable Strong cutting. At present, most of the products of the engraving machine on the market are mainly processed crafts, and the cost is low. Due to its low precision, it is not suitable for mold development, but there are exceptions, such as wafer engraving machines.




      Maybe someone will have this problem. Is the engraving machine an engraving machine?

      The insiders told the author that people intuitively feel that the small format is an engraving machine, and the large format is an engraving machine, an engraving machine, or a router, or simply a large engraving machine. In fact, they are two different machines, but they work roughly the same way. They are driven by three axes of x, y and z and are controlled by an electronic controller.




      In addition, from the purpose of use, the engraving machine is mainly used for plate engraving, such as: woodworking engraving machine, engraving machine, aluminum plate engraving machine, four-axis, five-axis engraving machine engraving machine, engraving machine, relief engraving machine, CNC wood engraving machine, Engraving machines, tombstones, etc. It is widely used in two-color plates or acrylic engraving. The depth of engraving knives is about 1mm~3mm. The logos and signs used are more common. From the mechanical structure point of view, the spindle head of the engraving machine is equipped with a spring pressure nose, which is used to flatten the thin plate below 3 mm during the engraving process. At the same time, since the engraving axis is connected to the larger diameter motor through the belt, the speed is larger and the engraved workpiece is smoother. Due to the long tool used in the engraving machine, it is only suitable for high-speed engraving processes with low cutting ability.




     If the engraving machine is used for three-dimensional engraving, although the reduction is large, a large number of knives, 200mm wide material can be completed at one time. In addition, the engraving and milling machine has the flexibility to select the tool diameter and length specifications, slowly drying with a fine knife, and working with a thick shank. .


     Because the design of the engraving and milling machine is mainly focused on heavy loads, large steel frames and large Z-axis strokes. Therefore, it can not only make the technology of the small engraving machine, but also cut the high speed and feed rate of the plate, which can reach 20mm ~ 30mm at a time, which is a process that the engraving machine can't do. In this sense, engraving machines and milling machines can be finely engraved, and cutting, engraving and milling can be done.


     With its technical advantages and reasonable price, the engraving and milling machine has become an important machine tool for consumer electronics parts manufacturing, small precision mold manufacturing, hardware products, furniture manufacturing and other industries. In addition, CNC engraving machines have also been used in the fields of high-power LED aluminum substrates, craft gifts, metal electrodes, and metal eye frame processing.

Advertising word laser cutting machine precision and advantages?

1, advertising word laser cutting machine accuracy: different brand models of advertising word laser cutting machine accuracy is different. Specifically, you can consult the manufacturer.

2, advertising word laser cutting machine advantages:

(1) High cutting precision: High-precision laser cutting technology is adopted to cut the surface of the material and at the same time, a pure auxiliary gas can reflect the perfect cutting effect.

(2) Non-contact processing: The laser cutting machine can accurately cut the curve pattern on acrylic, two-color board and other materials. Since the laser cutting machine is non-contact processing, it does not crush the material, and the incision is smooth, and there is no need for secondary rework.

(3) High flexibility: The laser cutting machine has high flexibility and can process some complex graphics, which not only reduces the difficulty of processing products, but also improves the diversity of products. For advertising companies, laser cutting machines can not only increase the added value of products, but also reduce processing costs and increase additional profits.

The high-quality laser cutting machine can produce beautiful advertising word signs, with high precision of cutting words, one-time cutting, and no secondary processing. Cutting stainless steel characters can be used to make fine characters; in addition to cutting stainless steel plates, laser cutting machines can cut metal materials such as aluminum plates, and precision laser cutting machines can cut non-metallic materials and cut fine.

What are the specific steps for using the advertising engraving machine?

1. Double-click to open the engraving software and set the layout according to the material size in millimeters.

2. Edit the file in the space area of ​​the page.

3. After making the file, place it in the position of the material to be processed to generate the desired processing path.

(1) The 2D path is two-dimensional engraving. Generally, the engraving depth of the two-dimensional engraving is fixed, that is, according to the engraving depth of the design, the milling process is performed from the surface of the object, and finally the ideal effect of the design is achieved. The specific operation is as follows: point 2D pop-up two-dimensional engraving mode dialog box, select "intaglio" in the "engraving depth" to set the depth to be processed, and select the tool compensation. The engraving method selects “horizontal milling bottom” to select the knife through the tool magazine, and the secondary machining method selects the hook edge, and also selects the same knife through the tool magazine. Select counterclockwise, and select the automatic check error and automatic decomposition self-intersection ring, point to complete the path creation, then the computer automatically calculates the path, which is the green part. (Note: If there is no required tool, fill in the corresponding parameters in the "Tool parameters" column, click "Add tool" - "OK". This will add a tool).

(2) 3D path is three-dimensional engraving, three-dimensional engraving, which means that the system automatically changes the depth of engraving according to different graphics and tools, ensuring that the engraved surface is consistent with the design object. Commonly known as the "three-dimensional clear angle" function. The specific operation is as follows: point 3D pops up the 3D engraving mode dialog box, and selects the depth of the "inscription" in the "engraving depth". Remove the checkmark in front of the "rough knife milling". In 3D finishing, the tool is selected by the tool magazine, and most of the centering tools are selected. Select counterclockwise, and select the automatic check error and automatic decomposition self-intersecting ring, and click to confirm the completion path creation.

(3) The word cutting path actually refers to cutting the object to be processed from the engraving material by using a milling cutter. The usual processing methods are processing on the inside and outside contours. The “outer profile” is cut along the outside of the designed graphic. The cut part is the designed figure. The "inner contour" is cut along the inside of the designed pattern. The part left is the graphic designed. When the inner and outer contours are being cut, the Wentai system automatically sorts them and counterclockwise and clockwise directions. “Original line output” means that the design graphic is output as it is, and single line words and graphics must be output as they are.

Operation mode: Select the contour according to the need, use the outer contour when cutting the word, use the inner contour when hollowing out, or use any contour when using the center sharp knife when 3D inverted. The depth of engraving is generally 0 when cutting, the knife is on the table top; when it is inverted, set the depth according to the need, the knife is on the material. Select tool compensation. Use the same hour hand when making the panel and the bottom plate.

4. After checking the correct path, click the “Save engraving path” pop-up window. When the “lifting knife distance” is cut, the material thickness is increased by 7~9. In the “output only selected part”, check the number and click “Output file”. Find", select the Chunlan disk location to be saved after popping up the dialog box, select "G-codefiles(*.nc)" after "Save Type", enter the file name after "File Name", and click "Save" to return to the window. , click "Confirm".

5. Open the "Engraving Machine Control System", click "Open and Load" under the "File" menu to find the saved file name in the pop-up box, and click "Open".

6. Click “Simulation” and right click in the blue area. Select “Adjust to Window Size” and you will see the opened content and check if it is the desired one.

Note: Make a mark at the position of the workpiece origin when starting machining.

Things to pay attention to when purchasing an engraving machine

1. The first thing to mention is the strength of the engraving machine.

So what affects the strength of the engraving machine? Of course, the motor power is gone. In general, the tool can be clamped to 12.7 when the power is above 3KW.

As everyone knows, the engraving machine has the power of size and power. Small power engraving machines generally only engrave small signs, three-dimensional crafts, two-color boards, and so on. The high-power engraving machine is different, and there are many things that can be engraved. There are two types of high-power engraving machines, namely large-format engraving machines and medium-sized engraving machines. Large-format engraving machines generally refer to webs of more than one meter; medium-sized engraving machines can be used for fine processing and organic signage.

2. The second is the speed of the engraving machine.

The speed of the engraving machine is actually a problem of processing efficiency. Under the premise of strong engraving machine, we hope to complete the production task as soon as possible. At this time, we must consider the service life of the equipment. The speed of our engraving head motor is adjustable from a few thousand to 30,000 revolutions per minute. If the speed is not adjustable or the speed adjustable range is small, it means that the application range of this engraving machine is very limited. Because the rotational speed requirements for engraving of different materials are different.

3. The third is the precision of the engraving machine.

Whether it is carving or cutting, it is necessary to achieve long-term work and a good position, and the engraving surface should be smooth and not rough.

4. Finally, the function of the engraving machine should be complete.

Let's see if the engraving machine has functions such as vacuum adsorption, vacuuming, offline, and energy saving.

The so-called vacuum adsorption refers to the work of fixing the plate on the table. Ordinary engraving machines use platens to fix the plates, which may cause the plates to be underutilized.

The so-called vacuuming means that the engraving machine has a full-time vacuuming function, which can vacuum the dust during the processing and keep the work shop clean and tidy.

The so-called offline means that the device does not need to be connected by a data cable and a computer.

Energy-saving means that after the end of the work of the engraving machine, the spindle of the equipment can be automatically turned off and not operated, which can save electricity.

Finally, the screw and the guide rails. Good quality screws and guides are prerequisites for accuracy.

How many knives does the advertising engraving machine have?

The advertising engraving machine has roughly four kinds of tools, namely a flat-bottomed sharp knife, a straight knife (column knife), a milling cutter, and a three-dimensional shaped knife.

How many kinds of knives are there for advertising engraving machines?

1, flat-bottomed knife:

W1: indicates the diameter of the tool holder. The common tool holder diameter is ∮3.175, ∮4, ∮6, root.

Set as needed.

W2: Indicates the width of the tool tip. It directly affects the engraving effect. It should be as accurate as possible when setting. You can take a high-precision ruler for general reference.

A: Half of the angle between the two sides of the tip portion. If it is a 30° tool, A is set to 15, and so on.

2, straight knife (column knife):

W1: The width of the front end of the cutting edge. The common width is 2MM, 1.5MM. Generally, it is slightly smaller when it is set. Because the front end is convenient for chip removal, the side edge is repaired, so the actual width is slightly smaller.

H1: The length of the cutting edge of the tool, the height of the material to be cut should be lower than the length of the blade. Generally, the H1 is set to about 5 mm.

3, milling cutter:

W1: the width of the front end of the tool, the diameter of the commonly used shank is ∮3.175, ∮4, ∮6; if the thickness of the cutting material is less than 10MM, when using ∮3.175 knives to cut the word to be deformed, sometimes using the shank diameter Change from ∮3.175 to a shank tool with a ∮2 or ∮1.5 at the front end.

H1: the length of the blade, the thickness of the cutting material should be lower than the length of the blade. Generally, H1 is divided into the following types according to the thickness of the material (2 mm more than the cutting material, which is convenient for chip removal).

4, three-dimensional shaped knife:

W1: The diameter of the big knife under the shank is randomly matched to 32mm; there is also a smaller one for cutting.

Cut small three-dimensional words.

A: Half of the angle between the two sides of the tip part. Because the 90° tool is randomly matched, A is set to 45 (similar to a flat-bottomed knife)

W2: The width of the tool tip. Because the specific path is calculated when the three-dimensional path is calculated, it has no meaning. Usually 0.1 or 0.2 is required.

How many knives are used in advertising engraving machines?

1. Flat-bottom sharp knife: use W2 or A small knife when carving small characters, use large knife as much as possible to increase the processing speed; the tool selection is subject to the narrowest stroke; if necessary, without affecting the font effect, available The node edits and modifies the strokes to facilitate the path of the oversized knife; the engraving badge is commonly used for 30° knives; if the word is too small, it can be replaced with a single line and then “cut” to calculate the path.

2, straight knife (column knife): Therefore, the kind of tool is mostly used for large-scale carving on the department card, so it is also called the department card knife, but the engraving effect is slightly inferior to the flat-bottom knife of the same width. The edge of the material it cuts is a straight edge, and the edge of the material cut by the flat-bottomed knife has a beveled edge. The degree of tilt depends on the angle of the tool. The angle is large and the edge slope is larger.

3. Milling cutter: It is not recommended to cut 10MM and below materials with 22mm cutter, which may lead to broken knife; when there is no 22mm cutter, it is necessary to cut 20MM material, and can temporarily use 17mm cutter to realize by layer cutting.

12mm: Cut 10MM and below materials

17mm: cut 15MM material

22mm: cut 20MM material (PVC is more than 3.175; acrylic is used ∮ 4)

4. Three-dimensional shaped cutter: Because this kind of cutter is different from our common ones, it uses a single alloy shank material to directly grind the various engraving tools required for the work, but it is welded under the shank of ∮6 through a special welding process. The cutter heads in various shapes are directly used for engraving of various special shapes, so they are also called big-headed knives.

What are the scopes of several types of knives for advertising engraving machines?

1, flat-bottomed knife:

Engravable materials: two-color board, PVC board, plexiglass, ABS board, etc.

Cuttable material: two-color board, ABS board.

2, straight knife (column knife):

Engravable materials: two-color board, PVC board, plexiglass, ABS board, etc.

Cuttable material: two-color board, ABS board.

3, milling cutter:

Engravable materials: PVC board, plexiglass, wood board, etc.

Cuttable materials: PVC board, plexiglass, wood board, etc.

4, three-dimensional shaped knife: three-dimensional clear angle words (using the "3D" function to calculate the path) and the back oblique edge of the crystal card.

What are the precautions for the advertising engraving machine?

1. When cleaning, use a gasoline or WD40 cleaning agent to clean the chuck and pressure cap.

2. Put the chuck into the pressure cap, otherwise the cutter is not easy to install. If the chuck is not clamped in the pressure cap, the chuck will be caught in the motor shaft when the knife is unloaded.

3. Before clamping, pay attention to whether the chuck matches the selected tool, otherwise the tool cannot be tightened.

4. When clamping the tool, the part of the tool that protrudes out of the chuck should not be too long, otherwise it will easily generate vibration during the machining process, which will affect the processing quality of the workpiece surface.

5. When changing the tool, it must ensure that the spindle speed is zero, that is, the tool can be dismantled when the spindle is stopped, otherwise serious personal injury accidents may occur.

6. If you use the presser foot to engrave, you must use a vacuum cleaner to clean the dust on the presser foot and the spindle, and then clamp the tool.

7. In the process of screwing up the cap upwards, be sure to press the cap on the positive rotor thread, first screw it in place with no effort.

8. When unloading the knife, use an air gun to clean the dust on the pressure cap and the rotor shaft before unloading the knife.

How can the advertising engraving machine be used without damaging the tool?

1. Whether the engraving machining allowance is reasonable, whether there is a stepped margin, so that there will be a change in the cutting force caused by the vibration during the machining, resulting in the broken knife, so it is necessary to increase the semi-finishing. The other is whether the amount of knife is too large.

2. Whether the power supply provided by the engraving machine is stable or not, the unstable power supply will also cause the engraving machine to break the knife.

3, check whether the priority mode of the advertising engraving machine is correct, it directly affects the starting speed of the machine tool, the higher the starting speed, the more likely it is to generate vibration, which will easily lead to broken knife

4. Whether there is dust on the engraving machine tool and the chuck, whether the upper knife is too strong. The chuck and nut are not intact. It is very important that the amount of tool sticking is large. It is often a problem here and it is not taken seriously.

5, the tool problem: mainly related to the hardness, strength, sharpness of the tool of the advertising engraving machine and the length of the special tool extension, the degree of smoothness of the tool rake face. This requires the user to select the correct tool for machining before machining.

6. Whether the materials processed by the advertising engraving machine have impurities and the hardness of the material is too large.

7. Whether the advertising engraving machine is flattened at the bottom of the machine, if it is not leveled, it may cause a broken knife. Whether the spindle motor speed is too low, the spindle motor speed is too low, the amount of knife per tooth per revolution becomes larger, so the cutting force becomes larger, which will cause the knife to be broken. Generally speaking, the spindle speed we use is still high. Some are good.

The wood engraving machine is not evenly carved, and the depth of the knife is shallow. What is the problem?

When the woodworking engraving machine is processed, in normal terms, the depth is based on the design of the map in advance. For example, the lower knife should be 0.5cm, and the actual engraving depth is 0.5. However, when there was a problem, it was found that there were some places where the 0.5 was 0.2, and some places even reached 1. This is a headache.

If you find a problem, if you want to solve the problem, you must first understand where the problem has occurred. Generally, the wood carving machine is unevenly carved, which is generally the following aspects:

1. The control card is loose or faulty

2. Step near motor failure

3. Driver failure or current breakdown is inconsistent with software settings

4.z axis motor line failure

5. Spindle motor failure

6. Inverter interference or data setting is incorrect

7. Static interference

8. Computer virus or system problem

Woodworking engraving machine has this kind of failure, the best solution is to check. Most of them are discharged according to the actual situation, and then checked one by one. Of course, the first problems with the driver, motor, inverter, etc., it is better to find a better solution.

Woodworking engraving machine hollow carving

      There are many techniques for traditional engraving, and hollowing out is one of them. The exterior looks like a complete pattern, but it is empty inside or inlaid with small hollow objects. Five thousand years ago, the late Neolithic pottery had an openwork hole, and the thin tire black pottery unearthed from Dawenkou in Shandong had a variety of hollow patterns on the handle. The various types of ceramic aromas from the Han Dynasty to the Wei and Jin Dynasties were all translucent; after the Song Dynasty, the hollow decoration was growing; when Qing Emperor Qianlong (1736-1795) burned into the hollow, turned the neck and hollowed out the bottle, so that the process reached peak. As well as the inner courtyard of the palace to the ordinary people's homes, the decorative carvings of some doors and windows used, the carvings of the screens, etc., the beautiful artistic reliefs, etc., were originally carved out by hand for a long time. Now using the CNC woodworking engraving machine, it can be engraved quickly, greatly improving the work efficiency. The main advantage of CNC woodworking engraving machine is the fully automated engraving and embossing, which is the hollow carving that people often say. Cnc CNC woodworking engraving machine can also be called CNC hollowing machine, or called cnc CNC engraving and milling machine. The woodworking engraving machine engraves a pattern or text that penetrates the object on the object.
