Engraving machine

The engraving industry introduction has the unique strengths and inherent weaknesses as other machine tools! If the CNC engraving object is selected correctly and the process is used properly, CNC engraving can become a profitable career! If the CNC is sculpted into the wrong line and is in a weak position, CNC engraving will be “difficult” and investors’ returns will be low. Because the characteristics of CNC engraving objects are complex patterns, peculiar shapes and fine finished products, while CNC engraving machines are mainly lightweight structures, this actually limits the working mode of CNC engraving: “Quick milling of small cutters”. In fact, this is also the reason. It is the "professional advantage" of CNC engraving. The reason is that CNC engraving is doing "the business that conventional large cutting tools cannot process!" Thanks to the unique professional advantages of CNC engraving, CNC engraving methods are applied more handily in the following industries: mold engraving industry and advertising engraving industry.

Engraving machine classification Computer engraving machine has two types of laser engraving and mechanical engraving, both of which have high power and low power. Because the scope of application of the engraving machine is very wide, it is necessary to understand the most suitable range of applications for various engraving machines: 1. Nameplates: low-power laser engraving machines (engraving machines), high-power or low-power computer engraving machines; Architectural model: large and small power computer engraving machine;

3, metal (mold, chapter, etc.) processing: large and small power computer engraving machine (high power for each cutting amount and save time); 4, crystal word production: high power laser engraving machine (50W above), large Power machinery engraving machine; 5, wood, organic glass, artificial stone and other signs production: high-power mechanical engraving machine;

6, display, exhibition model production: high-power, large-format mechanical engraving machine.

The application knowledge of engraving machines is well-known. Hand-carving is a kind of original craftsman-type work. It is an integrated activity of the "high intelligence and high-skilled" of the carver. Whether carving products can become treasures depends entirely on the understanding of the arts, the feeling of the material. Carving skills and tireless spirit. The development of the computer engraving machine has brought the carving art to a higher level and has gradually become a professional tool for the advertising industry. At present, "engraving" has become an art, a culture, a symbol of the spirit. Computer engraving machine is divided into two types of high power and low power. The low power is only suitable for two-color panels, architectural models, small signage, three-dimensional crafts and so on. Because the power is too small, it greatly affects the scope of its application. High-power engraving machines can do small power engraving machines. The most suitable for large-scale cutting, relief, sculpture.

Sculpting is mainly used in: advertising, crafts, mold, construction, printing and packaging, wood, decoration and so on.

Sculpture supplies are: Acrylic organic board, PVC board, Hibiscus board, two-color board, wood board, density board, marble, fire board, rubber board, glass and so on. Engraving electromechanical spindle motion control in CNC machine tools, electrospindle usually adopts frequency control method. At present, there are three kinds of control methods: ordinary variable frequency drive and control, vector control drive and control, and direct torque control. Ordinary frequency conversion is scalar drive and control, and the drive control characteristic is constant torque drive, and the output power is proportional to the rotation speed. The dynamic performance of common frequency conversion control is not ideal, the control performance is poor at low speed, the output power is not stable enough, and it does not have the function of C axis. But the price is cheap, the structure is simple, generally used for grinding machines and ordinary high-speed milling machines. The vector control technology imitates the control of the direct current motor, uses the rotor field orientation, uses the vector transformation method to realize the drive and control, and has good dynamic performance. The vector control driver has a large torque value when it is just started, and the electric spindle itself has a simple structure and small inertia, so the starting acceleration is large, and the allowable limit speed can be achieved instantaneously after starting. This kind of driver has two kinds of open loop and closed loop, the latter can realize position and speed feedback, not only has better dynamic performance, but also can achieve C axis function; while the former is slightly less dynamic performance, does not have C axis function , but the price is cheaper. Direct torque control is another new type of high-performance AC speed regulation technology developed after vector control technology. Its control concept is novel, the system structure is simple and clear, and it is more suitable for the drive of high-speed electric spindle, and can also satisfy the high-speed electric spindle. The requirements for dynamic characteristics and static characteristics of high-speed, wide-speed range, and high-speed instant quasi-stop have become a hot technology in the AC drive field.
