Cnc Engraving Machine

Engraving is a combination of drilling and milling in terms of processing principle, and the engraving machine has multiple data input modes as needed. There are two types of computer engraving machines: laser engraving and mechanical engraving, both of which have high power and low power. Because the application range of engraving machines is very wide, it is necessary to understand the most suitable application range of various engraving machines. Low power is only suitable for two-color boards, building models, small signs, three-dimensional crafts, etc., while carving jade, metal, etc., the power is more than 1500W. The high-power engraving machine can be used as a small-power engraving cnc machine. It is most suitable for large-scale cutting, embossing and carving.

In the numerical control machine tool, the electric spindle usually adopts the frequency conversion speed regulation method. There are mainly three control modes: ordinary variable frequency drive and control, vector control drive and direct torque control.

Ordinary frequency conversion is scalar drive and control, and its drive control characteristic is constant torque drive, and the output power is proportional to the speed. The dynamic performance of ordinary frequency conversion control is not ideal, the control performance is not good at low speed, the output power is not stable enough, and it does not have the C-axis function. However, it is cheap and simple in structure, and is generally used for grinders and ordinary high-speed milling machines.

The vector control technology imitates the control of a DC motor, oriented by the rotor magnetic field, and realizes the drive and control by the method of vector transformation, which has good dynamic performance. The vector control drive has a large torque value when it is just started. In addition, the electric spindle itself has a simple structure and small inertia, so the starting acceleration is large, and the allowable limit speed can be reached instantaneously after starting. This kind of drive has two kinds of open loop and closed loop. The latter can realize position and speed feedback, not only has better dynamic performance, but also can realize C-axis function; while the former has poor dynamic performance and does not have C-axis function. , But the price is cheaper.

Direct torque control is another new type of high-performance AC speed control technology developed after vector control technology. Its control idea is novel, the system structure is simple and clear, and it is more suitable for the drive of high-speed electric spindles and can satisfy high-speed electric spindles. The dynamic and static characteristics of high speed, wide speed range, high speed and instant stop have become a hot technology in the field of AC drive.

Scope of application:

  • Granite, marble, bluestone, sandstone and other stone carvings
  • Hard stone such as granite can be carved in layers to 5mm
  • Marble, bluestone, etc. can be carved up to 5mm at a time


1. Stepper driver + stepper motor

The stepping system is currently the most used drive system on the market. The most popular is the three-phase hybrid stepping motor, which accounts for more than 90% of the market share. The reason is that the price is low and it is equipped with a high-segment drive. The effect is good. But the defects are also more obvious, such as: resonance, noise, increase in speed, decrease in torque, prone to losing steps after working for a long time, and excessive temperature rise of the motor.

2. Hybrid servo drive + motor

The use of hybrid servo has not been popular in China. There are many reasons for this. There are not many foreign manufacturers of hybrid servo, and the price has no great advantage compared with AC servo. It can only be used in some special industries. Improvements include: improving high-speed performance, reducing heat generation, and reducing resonance.

3. AC servo drive + AC servo motor

The use of AC servo in engraving machines is still relatively small. The main reason is that the price is relatively high. In addition, the application of AC servo has certain requirements for the structure of the machine tool, electrical appliances, control systems, and transmission systems. It is the same as the barrel principle, the shortest The board determines the amount of water in the barrel, so AC servos are generally used in high-end models. The AC servo has: fast response, large torque, high speed, high precision, low heat generation, continuous long-time work, complete alarm system, etc. Disadvantages: Different equipment needs different servo parameters, and the adjustment parameters require high-level technical engineers.

Purpose and application

Paper cutting, greeting cards and other paper craft cutting and marble, granite, glass, crystal and other decorative materials engraving and marking.

The working principle of laser embroidery is to use the high-intensity laser emitted by the laser to control its movement trajectory by the advanced galvanometer, and to carve and perforate various fabrics to create a fashionable and trend-leading effect. It is essentially different from the effect embroidered by an embroidery machine.

  • First of all, from the visual point of view of the pattern, the embroidery machine affixes threads of different colors to the surface of the clothing fabric, and combines the color blocks into a pattern; while “laser embroidery” is processed according to the background color of the clothing fabric , Through the layering method of the laser control system, “embroider” on the fabric of the same color, the transitional colors with different shades and layers of the fabric background color are “embroidered”. This kind of natural transitional color system contained in the fabric background color cannot be deployed by any designer. It has a unique, natural and simple style.
  • Secondly, in terms of form of expression, the embroidery machine cannot continuously express single-line fine and large-format patterns due to its working characteristics; while “laser embroidery” is because of its slender beam, high-speed movement, and high-speed movement. Continuous engraving, so it is complementary to the embroidery machine. The laser cutout graphic women’s clothing that has just been popular this summer has a special effect by using laser drilling to directly form the graphic. Although the unit price of processing has increased to ten to twenty yuan, the supply is still in short supply. Fashionable products must be innovative in order to become popular. At present, this technology is also applied to the denim processing industry to produce images, flower shapes, cat whiskers and other effects on denim clothing. With the advantages of high efficiency, energy saving, and pollution-free, laser bleaching is believed to gradually replace denim in the near future. This process of sandblasting.

The technical method of using laser engraving machine for wooden materials

1. Logs (unprocessed wood)

Wood is by far the most commonly used laser processing material and is easy to engrave and cut. Light-colored woods like birch, cherry or maple are easily vaporized by laser, so they are more suitable for engraving. Each kind of wood sign production has its own characteristics, and some are denser, such as hardwood, which requires greater laser power when engraving or cutting. It is recommended to study the carving characteristics before carving unfamiliar wood.

2. Plywood

Carving on plywood is actually not much different from carving on wood, but there is one thing to note, the depth of the carving should not be too deep. The edge of the cut plywood will be as black as wood. The key is to see which kind of wood the plywood is made of.

Wood Carving

Generally speaking, the engraving on wood is usually a negative engraving, and the depth of the laser marking machine is generally deeper. The power is generally set higher, if it encounters harder wood, the color of the engraved graphics may become darker. If you want to make the color lighter, you can increase the engraving speed and try engraving several times. Some wood will produce some oily smoke attached to the surface of the wood when carving. If the wood has been painted with a damp cloth, it can be carefully wiped off. If it is not painted, it may not be wiped clean, causing the surface of the finished product to be stained.

Wood Cutting

The laser engraving machine generally does not cut wood deeply. The maximum cutting depth depends on the wood material and laser power. If you want to cut very thick wood, you can slow down the cutting speed, but it may cause the wood to burn. In the specific operation, you can try to use large-size lenses, and use the method of repeated cutting.


After wood carving cnc machine, there will generally be a feeling of being burnt. It has a primitive artistic beauty that matches the wood background color. The depth of its color mainly depends on the laser power and the carving speed. But some woods are usually softer, and you can’t change their color anyway (such as birch). For the coloring of the finished product, acrylic pigments can be used.

How To Buying CNC Engraving Machine

Clarify the nature of work

Don’t think that buying a single engraving machine can do all the work. Manufacturers divide engraving machines into various specifications and models in order to deal with various processing tasks. For example, if you buy a mold-level engraving machine to engrave two-color plates, or buy a large engraving machine to engrave seals, this will cause huge waste, and you will not get good results. Similarly, if you buy an advertising-grade engraving machine to make a mold, it may not be competent at all. Therefore, before you purchase the machine, you must fully explain to the sales staff the content of the work to be done in the book, including the size of the workpiece, the material of the material, the thickness of the material, the weight, the final engraving effect and requirements, etc.

Choose the right model

For the first purchase of a small advertising sign shop, which mainly produces three-dimensional light signs, crystal characters, two-color plates, and breast badges, advertising-grade ones should be purchased. However, the machine configuration should be further refined. If the main two-color board is made, the floating cutter head must be equipped, because it can ensure the same lettering depth when engraving on the large-format two-color board; but it is mainly used for sawing plexiglass crystal letters Yes, a high-power spindle above 800W should be selected. Otherwise, long-term heavy work with a low-power and high-precision spindle will accelerate bearing wear and loss of accuracy. Generally speaking, the engraving machine format is less than 600mm, which is not suitable for engraving two-color boards and other fine work, but more suitable for sawing characters and making some large plaques; the engraving machine with a format of about 600mm is a general-purpose engraving machine, which can be used as Fine work such as two-color board can also be used for rough work such as sawing.
For cylindrical or other special-shaped workpieces that need to be processed, some fixtures or rotating coordinate axes need to be installed, which requires a high Z-axis column and a large space between the table and the tool head, so a special machine can be used. If it is a seal shop that specializes in engraving seals, you can first equip a seal engraving machine: laser engraving machine is the best for engraving leather seals and atomic seals, while seals for engraving bronze, jade, and horns, use 6070, a combination of the two , Then all kinds of materials take all.

Trial carving before purchase

Before buying an engraving machine, in order to ensure your return on investment, you should let the salesperson or you do it yourself, and try to engrave the work you do most often. At the same time, calculate the work efficiency, observe the effect, fully test the machine performance, and truly know it.

Sign the contract

After deciding to purchase, the first thing to do is to sign a contract with the seller. The contract should specify the purchased model, configuration, price, delivery time and delivery method, training method, warranty clause and payment method.

After the contract is signed, a certain deposit should usually be paid according to the contract (except for those in stock).

After the delivery and training of the engraving machine arrives, a technician will usually come to the door to unpack the machine. After the power is turned on, carefully check whether the appearance is damaged and whether it is damaged by impact during transportation. If it is intact, check the random attachments for the machine configuration according to the contract and use the random manual. The machine is installed by technicians (including hardware installation, removal of fixtures, placement of the machine, various cables for connecting to the power supply, software installation, computer configuration, and installation of optional engraving software).

After installation, use the test pattern provided by the manufacturer to carry out the engraving test on the machine. If the engraving test is completed correctly, the delivery acceptance is complete.

Use and after-sales

1). Guarantee the use environment

The engraving machine is a high-tech mechatronics equipment, which has certain requirements for the working environment;
Avoid equipment that seriously affects the signal transmission of the engraving machine, such as strong electricity and strong magnetism. Such as: electric welding machine, launch tower, etc.
Use a three-core power supply to ensure good grounding and reduce interference.
The voltage is required to be stable to avoid large fluctuations, and it is best to use a voltage stabilizer.
The machine should not work for a long time in a strong acid or alkali environment.

2). Care and maintenance

Engraving machines are mostly used in processing business, and the processing produces more powder and dust. Pay attention to keep the screw rod, polished rod and other parts clean and lubricated during use, clean the dust and add oil to the transmission parts in time; the operator must clean and add oil in time, and it is strictly forbidden to remove and plug when the power is on.

3). Software use problems

The engraving machine has numerous softwares available. In order to meet your engraving requirements, please select the correct operating software.

4). Processing issues

1. The rationality of the processing technology

Besides relying on the engraving machine to ensure the processing accuracy, reasonable processing technology is also very important. In order to ensure the accuracy of processing, please pay attention to the rationality of the processing technology.

2. Tool use

Because the manufacturing process and precision of the tool itself affect the machining accuracy, please select a tool suitable for machining when machining.

3. Operators

The proficiency and sense of responsibility of the operators also have a huge impact on the machining accuracy.

4. Wear and tear of the machine

It is inevitable that the engraving machine wears during use. As time goes by, the machine wear will reduce the accuracy of the machine.

Working Principle

The computer engraving cnc machine is composed of three parts: computer, engraving machine controller and engraving machine host. Working principle: The design and layout are carried out through the special engraving software configured in the computer, and the information of the design and layout is automatically transmitted to the engraving machine controller by the computer, and then the controller converts the information into a stepping motor or The signal (pulse train) with power of the servo motor controls the host of the engraving machine to generate X, Y, Z three-axis engraving tool path base diameter. At the same time, the high-speed rotating engraving head on the engraving machine cuts the processing material fixed on the worktable of the host machine through the tool configured according to the processing material, and can engrave various flat or three-dimensional relief graphics and texts designed in the computer. , Realize the automation of carving.

Mechanical Principle

The engraving machine’s multiple data input modes are easy to use according to needs. It can be compatible with a variety of engraving software, and it can also be compatible with JD software in the ENG format of the engraving machine.

The arc optimization command of the engraving machine can automatically eliminate the speed chattering lines according to the characteristics of the workpiece. Traditional CNC control systems often have the following problems: the curve speed is slower than the straight line speed, the curve accuracy is worse than the straight line, the machine shakes very badly and the speed is slow when doing three-dimensional relief, and the accuracy is poor. The application of this control system completely solves this problem, which not only improves processing efficiency (processing time can be shortened by 30%-300%), but also eliminates speed chatter marks and improves processing quality.

The engraving machine adopts widened high-precision cylindrical linear guide rail, which has good stability and high precision. The processing stroke is greater than 160 mm, which is higher than other equipment. It is especially suitable for making blister molds and contracting semi-finished products processing, so that the work is not limited to PVC, acrylic and other processing like other engraving machines.

During the processing of the engraving machine, the processing depth can be dynamically adjusted. During the machining process, the machining speed and cutting speed can be dynamically adjusted. The engraving machine is completely designed by Carter’s embedded CNC controller, which can be used in harsh environments. The industrial standard bus structure design ensures the stability and reliability of the control system.
