Woodworking engraving machine overview
Mainly used for wood processing, making it more beautiful. There are many types of woodworking engraving machines, and there are many brands, which leads to uneven prices.
Five points to choose woodworking engraving machine
First, woodworking engraving machine woodworking engraving machine
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 generally divided into two categories: precision machining spindles and high power cutting spindles. 1. The characteristics of the fine machining spindle are low noise, high speed and high precision, which are suitable for processing particularly fine workpieces such as seals, nameplates and badge gifts. 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 is not suitable for cutting thicker materials. 2, high-power cutting spindle, mainly used for cutting, high-power carving, characterized by high power, strong cutting ability, especially suitable for cutting words, 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 700--60000 rpm. Generally, the maximum speed of the brush AC motor does not exceed 24,000 rpm: B. The brushless variable frequency motor has high rotation precision, low wear and low noise, and its noise is much lower than that of brushed AC motor; C, brushless inverter motor stalling characteristics Well, because 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, no The brush frequency conversion motor adopts the frequency conversion control technology to adjust the 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 the high speed bearing. The brushed AC motor has a life of about 300 due to the use of the motor. The motor or motor carbon brush has to be replaced in an hour, so the carbon brush AC motor is usually not guaranteed for one day.
three. Control method and speed selection
The control methods can now be divided into three types: A. All calculations are done by computer control.
B. Controlled by a single chip microcomputer. C, using the USB port to transfer data, the system has a memory capacity of more than 32M. .
Fourth, the guide rail
The large-format engraving machine must use a widened imported square guide rail, which has more than 30 times the load capacity and precision retention capability of the circular guide rail, ensuring the high quality and high speed of the engraving machine.
Five, precision
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.
Six, SAJ frequency converter in the woodworking engraving machine application main features
1. Low frequency torque and stable output 2. High performance vector control 3. Fast dynamic response of torque, high precision of steady speed 4. Fast deceleration and stop speed 5. Strong anti-interference ability
