The era of woodworking engraving machines and stone engraving machines has arrived. Only a few years ago, imported engraving machines, regardless of size, were over 100,000. Recently, domestic automation technology has developed rapidly. At present, there are dozens of engraving machine manufacturers. The price competition has reached the price that the industry can accept. The vast number of operators have paid attention to the engraving machine. So, how to buy a suitable engraving machine?
What can an advertising engraving machine do in the advertising industry?
The plane engraving is specially designed for engraving two-color flat engraving materials. It can produce all kinds of badges, hanging tags, nameplates, etc., cutting characters, graphics, and various models of various materials.
In addition to the functions of the plane engraving machine, 3D engraving can also engrave objects with depth control, such as 3D convex or concave solid words with graphics. It can produce high-grade plaques of plexiglass, PVC foam board, copper, aluminum, stainless steel and other materials, as well as crafts such as embossing and color carving.
Everyone knows more about these possibilities, but it is not very clear about the working principle and construction of the engraving machine.
First, the woodworking engraving machine spindle is a kind of DC motor through the belt drive spindle, the speed can reach 25000RPH, but because of the use of brushes, the life expectancy is about 300 hours, you have to replace the motor or motor brush, the characteristics of this type of motor The torque is large, but the accuracy of such motors is generally not ideal. The other is the use of variable frequency brushless motors, the speed can reach 60,000 RPM, no need to replace the carbon brush. Using frequency control technology, it is a professional-grade product. There are also woodworking edger or point grinding heads that are widely used by some manufacturers. The speed can reach 25000RPM. Because the brush is used to replace the brush or motor every 300 hours, and the engraving precision is not high, it is mainly used for rough carving. . Professional grade is the use of high-precision high-power variable frequency speed control spindle, speed 7000-60000RPM.
Second, the floating knife head engraving the two-color board, often seems simple but actually not easy to do. The general user's idea is to require the manufacturer to provide a high-precision platform. Some manufacturers simply add a thick plexiglass plate to the platform and use a knife to mill a plane on it. However, it still can't solve the problem, because in addition to the error of the platform, the two-color board itself has errors. The double-sided glue that attaches the two-color board to the platform also has thickness, and other factors, so that the carved signs are still different in depth. . The floating cutter head is a weapon for engraving two-color plates, and small and medium-sized engraving machines in foreign countries are standard equipment. As the name implies, the floating cutter head is on the engraving plane and can float up and down within a certain range. The main shaft can slide up and down in the Z-axis direction. When using the floating cutter head, it pays attention to adjusting the distance between the floating cutter head and the cutting edge, and can engrave on a large uneven surface while maintaining the same engraving depth. Many domestic engraving machines say that their engraving machine has a floating cutter head, but some floating cutter heads are just a simple knife nose, which is used to press the object to be processed, which does not play a real role, otherwise the motor is too Do not float again, or scratch the machined surface. Otherwise, the motor is light and the power is not enough, which creates a problem.
