The wood engraving machine is mainly used for the processing of wood, and make it more beautiful, at present, there are many kinds of woodworking engraving machines on the market, and the quality and price of the products are also uneven. It’s necessary to select carefully when purchasing. Here are five points for purchasing the wood engraving machines.
1.Look at the size of the engraving machine.
The customer should select the model of the engraving machine and its power according to the needs of the business and the funding situation. Generally, the small-format engraving machine has 600mm×600mm and 600mm×900mm, and the feeding width is 700mm. The engraving two-color board is the most basic application of the small-format engraving machine, and the acceptance is very good. The price of the smaller engraving machine is similar to that of the engraving machine, but it is more troublesome and unnecessary waste when engraving the 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 plexiglass and PVC board on the market is now 1300mm× 2400mm, these models are suitable for customers who require large-format engraving machines.
2.Pay attention to the spindle motor of the engraving machine.
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 generally divided into two categories: precision machining spindles and high power cutting spindles.
The good machining spindle is characterized by low noise, high speed and height, and is suitable for processing particularly fine work pieces such as stamps, nameplates, badges and so on. Such motors are usually high-speed variable frequency motors with low power, typically below 250W. The disadvantage is that the ability to cut thick materials is poor and does not cut off thicker materials.
High-power cutting spindle, mainly used for cutting, high-power engraving, characterized by high power, strong cutting ability, especially suitable for cutting the universe, three-dimensional characters, of course, you can also make badges, nameplates, seals and so on. Such high-power spindles can be generally divided into brushless high-speed AC motors and brushed AC motors according to the characteristics of the motor. The main difference is: A, the brushless inverter motor has a high speed, and the shift range is 70060000 rpm, and generally there are The maximum speed of brush AC motor does not exceed 24000 rev / min: B, brushless variable frequency motor has high rotation precision, low wear and low noise, and the noise is much lower than brushed AC motor; C, brushless inverter motor has good blocking characteristics, due to There is a special current limiting circuit on the inverter. The short-time blocking will not burn the motor, and the brushed AC will burn out quickly when it is overloaded or blocked, and it cannot be repaired. D. Brushless inverter motor It adopts frequency conversion control technology to adjust speed. It is a professional-grade product with long service life. The manufacturer provides one-year free replacement. In the future, the motor can be maintained by replacing high-speed bearings. The brushed AC motor has a life of about 300 hours. The motor or motor carbon brush has to be replaced, so the carbon brush AC motor is usually not guaranteed for one day.
3.the selection of the control mode and speed of the engraving machine: the control mode can now be divided into three types:
A.All the calculation work is completed by computer control. When the engraving machine is working, the computer is in working state, and other typesetting work cannot be performed. This may cause the computer to malfunction and cause waste.
B.Using the control of the single-chip microcomputer, this controller can perform typesetting while the engraving machine works, but can not turn off the computer, which is actually equivalent to saving 7 computers, and reducing the waste caused by the computer's misoperation.
C.Using the USB port to transfer data, the system has a memory capacity of more than 32M. As long as you save the file, you can completely disconnect from the computer, turn off the computer, or perform other typesetting. This method greatly improves the working efficiency of the engraving machine.
4.Pay attention to its guide rails.
The large-format engraving machine must use a widened imported square guide rail, and its load capacity and precision retention ability are more than 30 times that of the circular guide rail, which ensures the high quality and high speed of the engraving machine.
5.the accuracy of the engraving machine. The small-format machine engraves 1mm Chinese characters, or the large-format engraving machine engraves 1.5mm small characters, which must be seen very clearly under the magnifying glass.
