Engraving machine of the time has come, in the only imports a few years ago, laser engraver, regardless of size are more than 100,000, and the recent rapid development of home automation technology, there are already dozens of manufacturers of laser engraver, intense price competition has been achieved industry acceptable price, the majority of the industry have expressed concern about the need to look up laser engraver. So, how to buy a laser engraving machine suitable then?

 

     In the advertising field, laser engraving machine can do it?

     Carved specifically for engraving flat panels such as two-color plane carving material, can produce all kinds of badges, hang tags, nameplates, etc., cutting material of all types of characters, graphics, and the production of various models.

     3D engraving flat finish except the function of laser engraving machine, but also can be engraved with the depth of control objects, such as with a touch of 3D convex or concave three-dimensional character graphics. Can be made plexiglass, PVC foam board, copper, aluminum, stainless steel plaque, such as advanced materials, but also the production of embossed, carved, such as color crafts.

     Everyone of these are probably more familiar with, but the working principle of laser engraver as well as the structure is not very clear

     First, one type of spindle is belt transmission by DC spindle motor, speed can be achieved 25000RPH, but because of the use of brush, Life expectancy at approximately 300 hours, you must replace the brush motor or motors, such motors are characterized by large torque However, the accuracy of such motors are generally not very satisfactory. The other is the use of variable frequency brushless motors, speed can be achieved 60000RPM, without replacement of carbon brushes. Using variable frequency control technology, is a major product class. At present, the use of laser engraver Roth is such a spindle. At present, some manufacturers have widely used in woodworking or planing machine to do grinding head spindle, speed up to 25000RPM, because of the use of brush was replaced every 300 hours or electric brush, and engraving precision is not high, mainly used for rough carving . The major class is the use of high-precision high-power Frequency Spindle, speed 7000-60000RPM, Roth Roth is currently used in laser engraver is this motor.

     Two, two-color plate floating head sculpture, often seemingly simple but in fact it is not easy to do. Mind the general user requirements are a high-precision manufacturers with a platform, some manufacturers simply add a piece of the platform on thick plexiglass plate, a knife at the top of a plane milling. But still can not solve the problem, apart from the platform because there is error, the board itself has a two-color errors, color plate affixed to put together on the platform there is also the double-sided adhesive thickness, and other factors, makes carving out the depth of the sign is still different. Segment floating color plates are carved weapon at the small and medium-sized foreign engraving machine are standard. As the name suggests is a floating head on carving plane, must be in the range of plus or minus up. At the direction of Z-axis spindle is on the slide up and down, when focusing on the use of floating head floating in the head and adjust the distance between tip can be in large print on uneven sculpture, and to maintain consistent depth engraving. Lot of domestic engraving machine that their engraving machine with floating floating Segment Segment but only some - a simple nose knife used to hold objects to be processed, the role really would not serve any purpose, or else is the motor too not be re-floating, or surface scratches. If it is not enough electrical power light on the formation of such a problem. Roth Machinery Co., Ltd. After the development of computer research, has finally solved the problem with high-power motor, and the floating part of the rotor motor is, so starting with engraved badges to RT4500, there is no question of varying depth. At present, the country has applied for design patents.
