Characteristics and classification of spindle motor for wood engraving machine

 As the centerpiece of the carpenter carving machine, the spindle motor is the accessory. The spindle motor is the main component of the computer engraving machine, and its function has a major influence on the function of the computer engraving machine. The machining spindles are divided into two categories: fine machining spindles and high power cutting spindles.

1. The precision machining spindle features low noise, high speed and high precision. It is suitable for processing special precision workpieces such as stamps, nameplates and badges. This type of motor is a high-speed variable frequency motor with low power, usually below 250W. The defect is that the ability to cut thick data is poor, and it is not appropriate to cut thicker data.

2, high-power cutting spindle, the first is used for cutting, high-power carving, characterized by high power, cutting ability, special suitable for cutting words, three-dimensional characters, of course, can also make badges, nameplates, seals and so on. 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 difference is: A, the brushless inverter motor has a high speed, and the shifting limit is 700-60,000 rpm. The ordinary brushed AC motor Highest speed does not exceed 24000 rev / min: B, brushless inverter motor has high torsion precision, low wear, low noise, its noise is much lower than brushed AC motor; C, brushless inverter motor stall characteristics Well, because there is an extraordinary current limiting circuit on the inverter, the short-duration of the stall 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, no The brush frequency conversion motor adopts the frequency conversion control skill speed regulation, is a professional grade product, has a long service life, and the manufacturer supplies one year free replacement. In the future, the motor can be maintained by changing the high speed bearing, and the brushed AC motor has a service life of about 300. The motor or motor carbon brush has to be changed in an hour, so the carbon brush AC motor is not guaranteed for one day.

The importance of accuracy to woodworking engraving machines

Our company is a professional engraving machine manufacturer, engaged in woodworking engraving machine, advertising engraving machine, stone engraving machine, laser engraving machine, cylindrical engraving machine, CNC engraving machine and other numerical control equipment research and development, production, sales, maintenance services as one of the scientific research and manufacturing enterprises . Let's talk to you about the important reference accuracy when purchasing woodworking engraving machines.
      When choosing a woodworking engraving machine, try to choose a tool with high strength, sharp and smooth front rake surface, and try to use up-cut milling during finishing. The second is to pay attention to the correctness of the knife when you are on the knife. And guarantee the chuck,

The nut is clean and must be free of dust.
      What is important about the engraving machine engraving when it comes to explaining the woodworking engraving machine? If the accuracy of the engraving machine tool is not high enough, it is easy to cause the condition of the broken knife and scrap. This situation is generally caused by the inconsistent center of the rotation center of the engraving machine and the center of the engraving machine tool during the machining process. When the spindle of the engraving machine is running at high speed, if the spindle of the engraving machine and the tool are not inconsistent, it will not only affect the machining accuracy but also affect the machining effect.
