What aspects should be taken into consideration when selecting products for engraving machine manufacturers

At present, there are many types and numbers of engraving machines sold on the market, and the quality and price of products are also uneven. Therefore, engraving machine manufacturers should compare the following aspects when purchasing:

1. The Accuracy of the Engraving Machine

1 mm Chinese characters are carved on the small format machine, and 1.5 mm small characters are carved on the large format Lixin fine engraving machine, which should be seen clearly under the magnifying glass;

2. Look at the size of the engraving machine. Customers should select the model and power of the engraving machine suitable for them according to the business needs and financial conditions.

3. Pay attention to its guide rail

The large format precision engraving machine must adopt the widened imported square guide rail. Its load capacity and accuracy retention capacity are more than 30 times of the guide rail of the Yuanlixin precision engraving machine, ensuring the high quality and high speed of the precision engraving machine;

4. Pay attention to the spindle motor of the precision engraving machine

Spindle motor is an important component of the computer engraving machine, and its performance has a crucial impact on the performance of the computer engraving machine. The processing spindles are usually divided into two categories: precision processing spindles and high-power cutoff spindles.

1) The fine machining spindle is characterized by low noise and high speed, which is suitable for processing particularly fine workpieces, such as seals, nameplates and badges. This kind of motor is usually a high-speed variable-frequency motor with low power, generally below 250W. Its disadvantage is that the ability to cut thick materials is poor, which is not suitable for cutting thick materials;

2) The high-power cutting spindle is mainly used for cutting and high-power engraving. It is characterized by high power and strong cutting ability, especially suitable for cutting characters, three-dimensional characters, etc. Of course, it can also be used to make badges, nameplates, seals, etc. According to the characteristics of the motor, such high-power spindle can be generally divided into brushless high-speed AC motor and brush AC motor. The main differences are:

a) Brushless variable frequency motor has high rotation accuracy, low wear and noise, and the operating noise of Lixin fine carving machine is much lower than that of the brush AC motor;

b) Brushless variable frequency motor adopts variable frequency control technology for speed regulation. It is a professional product with a long service life. The manufacturer of the engraving machine provides a one-year free replacement package. In the future, the motor can also be maintained by replacing the high-speed bearing. As the service life of the brush AC motor is about 300 hours, the motor or the motor carbon brush must be replaced. Therefore, the carbon brush AC motor is usually not guaranteed for one day.

C) The speed of brushless variable frequency motor is high, and the speed range is 70060000 rpm, while the maximum speed of general brush AC motor does not exceed 24000 rpm;

d) The brushless inverter motor has a good locked rotor characteristic. Due to the special current limiting circuit on the inverter, a short time of blocked Lixin fine carving machine will not burn the motor, while the brush AC machine will soon smoke and burn when it runs under overload or locked rotor, and it cannot be repaired;

When purchasing an engraving machine, you need to carefully choose and compare more. Before purchasing, you can try to carve to buy a satisfactory engraving machine.
