There are many models of fine carving machines currently on the market, and the quality and price of the products are also uneven. Therefore, the following aspects should be compared when purchasing:
1. Accuracy of precision engraving machine
Small size machine engraving 1mm Chinese characters, large-format engraving machine carved 1.5mm small words, under the magnifying glass should be seen very clearly;
2, pay attention to its guide
Large-format engraving machine must use widened imported square rails, its load capacity and precision retention capability is more than 30 times that of round rails, ensuring the high quality and high speed of the engraving machine;
3, pay attention to the engraving machine spindle motor
The spindle motor is an important component of the computer precision engraving machine. Its performance has a crucial influence on the performance of the computer-engraving machine. The processing spindle is usually divided into two types: precision machining spindle and high-power spindle cutting.
1) The spindle of fine processing is characterized by low noise and high rotation speed, and is suitable for processing particularly fine workpieces such as stamps, nameplates, and badge gifts. This type of motor is usually a high-speed variable-frequency motor, and its power is relatively low, generally below 250 W. The disadvantage is that the ability to cut off thick materials is poor, and thicker materials cannot be cut off.
2) High-power cut-off spindle, mainly used for cutting, high-power engraving, characterized by high power, strong cutting ability, especially suitable for cutting, three-dimensional characters, etc. Of course, badges, nameplates and seals can also be produced. Such high-power spindles can be generally classified into brushless high-speed AC motors and brushed AC motors according to the characteristics of the motor. The main differences are:
a) Brushless variable frequency motor with high speed, transmission range of 70060000 rev / min, and the general brush AC motor maximum speed does not exceed 24,000 rev / min;
b) The brushless frequency conversion motor has high rotation accuracy, low wear, low noise, and much lower noise than the brushed AC motor;
c) The brushless frequency conversion motor has good stall blocking characteristics. Due to the special current limiting circuit on the inverter, short-time blocking will not burn the motor, and the brushed AC will smoke soon when overloaded or blocked. Burned, and not repairable;
d) Brushless frequency conversion motor adopts frequency conversion control technology, is a professional grade product, long life, manufacturers provide 1 year free replacement, in the future can also be replaced by high-speed bearings to maintain the motor, and brush AC motor due to the use of electricity The motor or motor carbon brushes have to be replaced after approximately 300 hours of service, so carbon brush AC motors are usually not warranted for one day.
4, see the size of the engraving machine format. The client should select the model and power size that suits his machine, based on the business needs and funding conditions.
When purchasing a precision engraving machine, it is necessary to carefully select a lot of comparisons. Before the purchase, you can try to sculpt and you will be able to purchase the engraving machine that you are satisfied with.
