The gravure electronic engraving machine is a modern equipment for making intaglio. It is made up of high technology of electronics, optics and machinery. It uses the principle of electrons and optics to make plates through mechanical and other physical methods. Mesh images are used to directly sculpt the meshes corresponding to the originals on the plate cylinder through automatic electronic scanning, tone control and engraving systems. The engraving systems of modern gravure electronic engraving machines include mechanical (diamond engraving), laser (CO2 laser) and electron beam engraving. The three types of electronic engraving machines do not have much difference in front-end processing, and they are only different from the engraving actuators. The most widely used on the market today are mechanical electronic engraving machines and laser engraving machines.

The main parameters

First, the size of the choice

The customer should select the model of the engraving machine that suits his needs and the size of the power according to the business needs and funding conditions. The small size of the general engraving machine is 600mm × 600mm and 600mm × 900mm, the feed width is 700mm. Engraving double-color board is the basic application of small-format engraving machine, and it is very acceptable. The price of a smaller engraving machine is similar to that of a smaller engraving machine. However, when engraving a two-color plate, it is necessary to cut the plate. This is cumbersome and unnecessary waste. Large-format engraving machines have 1200mm × 1200mm, 200mm × 1500mm, 1500mm × 2400mm, and 2400mm × 3000mm. The feed width of engraving machines for the above models exceeds 1350mm, and the sizes of organic glass and PVC plates on the market are 1300mm × 2400mm, so these models are suitable for customers who require large format engraving machines.

Second, the spindle motor

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 usually fall into two categories: precision machining spindles and high-power cutting spindles.

1. The characteristics of fine processing spindles are low noise, high rotation speed and height, suitable for processing particularly fine workpieces such as seals, nameplates, and badges. This type of motor is usually a high-speed variable-frequency motor with low power, generally below 250W. The disadvantage is that the ability to cut off thick materials is poor, and thicker materials cannot be cut off.

2. High-power cut-off spindle, mainly used for cutting, high-power engraving, characterized by high power, strong cutting ability, especially suitable for cutting Yu, three-dimensional characters, of course, can also make badges, nameplates, seals and so on. Such high-power spindles can be generally classified into brushless high-speed AC motors and brushed AC motors according to the characteristics of the motor. The main differences are:

A, brushless frequency conversion motor speed, transmission range of 7000 ~ 60000 rev / min, while the general brush AC motor maximum speed does not exceed 24,000 rev / min;

B. Brushless frequency conversion motor has high rotation accuracy, small wear, low noise, and much lower noise than brushed AC motor;

C. The brushless frequency conversion motor has good stalling characteristics. Because there is a special current limiting circuit on the inverter, short-time blocking will not burn the motor, and the brushed AC will smoke soon when it is overloaded or locked down. Burned, and not repairable;

D. Brushless frequency conversion motor adopts frequency conversion control technology. It is a professional grade product with long service life. The manufacturer provides 1 year free replacement. Afterwards, the motor can be maintained by replacing the high speed bearing. The motor or motor carbon brushes have to be replaced after approximately 300 hours of service, so the brushed AC motor is usually not warranted for one day.

Third, the choice of control methods and speed

Control methods can now be divided into three types:

A. All the computing work is done by computer control. The computer is in working condition when the engraving machine is working. It is impossible to do other typesetting work. This may cause the misuse of the computer to cause waste.

B. The use of single-chip control, this controller can work in the engraving machine at the same time typesetting, but can not shut down the computer, which in fact is equivalent to saving one computer, and reduces the computer's misuse caused by waste.

C, using USB port to transfer data, the system has more than 32M of memory capacity. As long as you save the file, you can immediately leave the computer completely, turn off the computer, or perform other types of layout. This way greatly improves the efficiency of the engraving machine.

Four, guide rail

The large-format engraving machine must use a wide imported square guide rail, which has a load capacity and accuracy retention capacity that is more than 30 times that of the round guide rail, ensuring the high quality and high speed of the engraving machine.

V. Accuracy

Small size machine engraving 1mm Chinese characters, or large-format engraving machine carved 1.5mm small words, under the magnifying glass should see very clear.
