There are many large and small companies in the market for machinery used in production, and the quality of the equipment sold by these manufacturers is uneven. When we buy a woodworking engraving machine, we have to choose the woodworking engraving machine according to what conditions. What is the quality of the woodworking engraving machine? If the manufacturer has to bargain for which parts must guarantee quality, which parts can be considered for price reduction. Next, follow the CNC network Xiaobian to understand what to pay attention to when buying woodworking engraving machine. Check the conditions of the woodworking engraving machine.
First, look at the size of the engraving machine. Customers should choose the model and power of their engraving machine according to their own needs. The popular small-format engraving machine has 600mm×600mm and 600mm×900mm, and the feed width is 700mm. The engraving two-color board is the most basic application of the small-format engraving machine, and the reception is very good. The cost of a smaller engraving machine is similar to that of a similar one, but it is more complicated and more unnecessary to sculpt when engraving a 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. The size of the plexiglass and PVC board in the current market is 1300mm. × 2400mm, so these models are suitable for customers who require large-format engraving machines.
Second, we must pay attention to the spindle motor of the engraving machine. The spindle motor is the primary component of the computer engraving machine, and its function has a crucial influence on the function of the computer engraving machine. There are two types of machining spindles in the world: precision machining spindles and high power cutting spindles.
1. The characteristics of the fine machining spindle are low noise, high speed and height. It is suitable for processing extraordinary fine workpieces such as seals, nameplates and badge gifts. This kind of motor is a high-speed variable frequency motor in the world, and the power is small, generally below 250W. The defect is that the material that cuts the thick material is poorer and does not cut the thicker material. Flange ball valve 2, high-power cutting spindle, mainly used for cutting, high-power engraving, characterized by high power, strong cutting ability, extraordinary suitable for cutting the universe, three-dimensional characters, of course, can also create badges, nameplates, seals and so on.
Such high-power spindles can be divided into brushless high-speed AC motors and brushed AC motors according to the characteristics of the motor. The main difference is:
A. The speed of the brushless inverter motor is high, the shifting limit is 70060000 rpm, and the maximum speed of the popular brushed AC motor does not exceed 24000 rpm:
B. Brushless variable frequency motor has high precision, low wear and low noise, and the noise is much lower than that of brushed AC motor; C, brushless inverter motor has good blocking characteristics, because of the special current limiting circuit on the inverter, short-term work The stalling will not destroy the motor, and the brushed AC machine will quickly destroy the smoke when it is overloaded or blocked, and it will not be repaired; D. The brushless inverter motor adopts the frequency conversion control technology to adjust the speed, which is a professional grade product. The service life is long, the manufacturer supplies one year free replacement, and the motor can be maintained by changing the high-speed bearing in the future. However, the brushed AC motor has to change the motor or motor carbon brush due to the use of the electricity life of about 300 hours, so the carbon brush The AC motor is not guaranteed for one day in the world.
Third, the engraving machine control methods and speed selection: control methods can be divided into three types:
A. All computer computing duties are completed by computer control. When the engraving machine is obligated, the computer is in a compulsory shape, and it is impossible to carry out other typesetting obligations. How can it be a misuse of the computer to constitute a waste product.
B. The use of single-chip microcomputer control, this controller can also be typeset in the engraving machine, but can not block the computer, which is theoretically equivalent to saving 7 computers, and adding waste from the computer's misoperation.
C, using the USB port to transfer data, the system has a memory capacity of more than 32M. Just keep the files in a safe place, you can completely separate the computer, block the computer or make other typesetting. This method has greatly improved the efficiency of the engraving machine. Fourth, we must pay attention to its guide rails. The large-format engraving machine must use a widened imported square guide rail. Its load capacity and precision are more than 30 times that of the circular guide rail, which guarantees the high quality and high speed of the engraving machine. Fifth, think about the accuracy of the engraving machine, small-format machine engraving 1mm Chinese characters, or large-format engraving machine engraving 1.5mm small characters, you must see very clearly under the extended mirror.
