The gravure electronic engraving machine is a modern equipment for making gravure. It is composed of high-tech technologies in electronics, optics and machinery. It uses electronic and optical principles to make plates through mechanical methods such as mechanical printing. With the mesh picture, through the fully automatic electronic scanning, tone control and engraving system, the mesh corresponding to the original is directly engraved on the plate cylinder. The engraving system of modern gravure electronic engraving machine includes mechanical (diamond engraving), laser (carbon dioxide laser) and electron beam engraving. These three ways of electronic engraving machine, the front-end processing is not much different, only the engraving actuator is different. At present, mechanical electronic engraving machines and laser engraving machines are mostly used in the market.
The main parameters
1. Selection of format size
Customers should choose the engraving machine model and its power suitable for their own needs according to the business needs and financial situation. Generally, small-format engraving machines have 600mm × 600mm and 600mm × 900mm, and the feed width is 700mm. Engraving two-color plate is the most basic application of small format engraving machine, and its acceptance is very good. The price of a smaller engraving machine is similar to it, but cutting the board when engraving the two-color board is more troublesome and causes unnecessary waste. Large-format engraving machines are 1200mm × 1200mm, 200mm × 1500mm, 1500mm × 2400mm, 2400mm × 3000mm, the engraving machine feed width of the above models are more than 1350mm, the size of the organic glass and PVC board on the market are now 1300mm × 2400mm, so these models are more suitable for customers who need 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 are usually divided into two categories: precision machining spindles and high-power cutting spindles.
1. The characteristics of the precision machining spindle are low noise, high speed, and height, which are suitable for processing particularly delicate workpieces, such as seals, nameplates, badges, gifts, etc. 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 thick materials is poor, and it is not suitable to cut thick materials.
2. The high-power cutting spindle is mainly used for cutting and high-power engraving. It is characterized by large power and strong cutting ability. It is especially suitable for cutting Yu and three-dimensional characters. Of course, it can also make badges, nameplates, seals, etc. Such high-power spindles can be generally divided into brushless frequency high-speed AC motors and brushed AC motors according to the characteristics of the motor. The main differences are:
A. The speed of the brushless inverter motor is high, and the speed range is 7000 ~ 60000 rpm, while the maximum speed of the brushed AC motor is generally not more than 24000 rpm;
B. The brushless frequency conversion motor has high rotation accuracy, low wear and low noise, and the operating noise is much lower than the brushed AC motor;
C. The brushless variable frequency motor has good stall blocking characteristics. Due to the specific current limiting circuit on the inverter, the short-term stalling will not burn the motor, and the brushed AC machine will quickly smoke when it is overloaded or stalled. Burned and irreparable;
D. Brushless frequency conversion motor adopts frequency conversion control technology for speed regulation. It is a professional-grade product and has a long life. The manufacturer provides 1 year free replacement. In the future, the motor can also be maintained by replacing the high-speed bearing. The life of the motor or motor carbon brush must be replaced in about 300 hours, so the carbon brush AC motor is usually not guaranteed for one day.
3. Selection of control mode and speed
The control methods can now be divided into three types:
A. All the calculation work is controlled by the computer. When the engraving machine is working, the computer is in the working state, and other typesetting work cannot be carried out. This may cause the wrong operation of the computer and cause waste.
B. It is controlled by single chip microcomputer. This controller can perform typesetting while the engraving machine is working, but it cannot turn off the computer. This is actually equivalent to saving a computer and reducing the waste caused by the computer's misoperation.
C. The USB port is used to transfer data. The system has a memory capacity of more than 32M. As long as the file is saved, you can immediately disconnect from the computer, shut down the computer, or perform other typesetting. This way greatly improves the working efficiency of the engraving machine.
Four, guide rail
Large-format engraving machines must use widened imported square guide rails, whose load capacity and precision retention capacity are more than 30 times that of round guide rails, ensuring high-quality and high-speed engraving machines.
V. Precision
Small format machine engraving 1mm Chinese characters, or large format engraving machine engraving 1.5mm small characters, should be very clear under the magnifying glass.
