Engraving machine classification: general categories are divided into advertising engraving machine, woodworking engraving machine, stone engraving machine, laser engraving machine. According to the above four points of view, you need to choose the structure, type, and transmission mode of the machine.
Engraving machine transmission mode: At present, the engraving machine is divided into three transmission modes, screw drive, rack drive and synchronous belt drive. Advantages and disadvantages of screw machine: Screw drive is the transmission mode when the engraving machine originates. It has high precision, slow running speed, high environmental requirements and relatively short service life. Y-axis single screw is not too long (model can't be too Large), it is easy to shake when running at high speed. If the installation accuracy is not high, the Y-axis screw will be cut off for a long time. If the accuracy is too high, the Y-axis double-screw structure can meet the requirements, and the general processing speed is about 7 meters. (Mainly applicable to advertising, wood products, small crafts, lighter stone can process any engraving material according to different tools)
Advantages and disadvantages of the rack machine: The rack machine is an upgraded version of the screw machine. The newly developed machine can not meet the requirements of high speed machining. The speed is fast and the environmental requirements are not harsh.
The relative service life is long and the precision is lower than that of the screw machine. The Y-axis of the rack machine Y-axis is the rack-and-pinion drive, and the Z-axis is generally the screw drive. The accuracy requirement is mainly determined by the meshing accuracy of the guide rail and the rack and pinion. The machine can be large enough in length and easy to maintain. It is usually equipped with a manual oil filling system. It is recommended that the processing speed be up to 15 meters. (Mainly applicable to the processing of woodworking products, paint-free doors, cabinet doors, solid wood doors, screens and other sheet cutting, hollow reliefs can also be processed advertising, stone, marble and other materials according to the tool selection)
Synchronous belt drive: Synchronous belt drive is mainly used for laser engraving machine and plasma cutting. It has the characteristics of light weight, high precision, good maintenance, long time and easy to relax and affect machining accuracy. (Laser machine is mainly used in advertising industry, handicraft carving, cloth, leather, glass, stone, crystal and other non-metallic materials such as shadow carving line carving, etc. It can also be processed on a few metal materials, the price range is related to the power of the laser tube) Introduction to driving system: At present, the engraving machine drive system is mainly divided into two major categories: stepping system and private service system. The stepping system occupies a dominant position. The reason is that the economy can meet the requirements of general customers. The stepping system belongs to the semi-closed loop system. Calculated by the step angle, the private service system is completely in the closed loop mode. Therefore, the measurement feedback system has high precision, and the power is large, the operation is stable, and the demand is high. The customer can select the machine of the private service drive system (the price is slightly expensive). At present, there is also a semi-private service system on the market, which is an improved version of the stepping system. Please pay attention when selecting the machine. (Sub-national and import) Control system: At present, Weihong, DSP operating system and mach3 are the main parts, and Taiwan Baoyuan and the new generation control system are imported.
