The common methods of the carving machine are: synchronous belt drive, screw drive and rack drive. Here are some of the advantages of the three drive methods:
1) Advantages and disadvantages of the screw machine
Screw drive is the transmission mode when the carving machine originates. It features high precision, slow running speed, high environmental requirements, relatively short service life, and the Y-axis single screw should not be too long (the machine type can not be too large). It is easy to shake during operation. If the installation accuracy is not high, the Y-axis screw will be cut off for a long time. If high precision is required, the Y-axis double-screw structure can be used to meet the requirements. The general processing speed is about 7 meters. Mainly used for advertising, wood products, small crafts and lighter stone, etc., according to different tools can process any engraving material.
2) Advantages and disadvantages of the rack machine
The rack machine is an upgraded version of the screw machine. The newly developed model is unable to meet the requirements of high speed machining. The speed is fast, the environmental requirements are not harsh, the relative service life is long, and the precision is lower than 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 is mainly determined by the meshing accuracy of the guide rail and the rack and pinion. The size of the machine can be large enough and easy to maintain. It is usually equipped with a manual oil filling system. The recommended processing speed is up to 15 meters. Mainly used for woodworking products processing, paint-free doors, cabinet doors, solid wood doors, screens and other sheet metal cutting, hollow carving, relief, stone, marble and other materials, according to the choice of tools. Of course, many advertising industries now choose to use the rack machine for production and processing because the rack machine has sufficient accuracy and speed.
3) Timing 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 slack, and affects machining accuracy. The laser machine is mainly used in the advertising industry, handicraft carving, cloth, leather, glass, stone, crystal and other non-metallic materials such as shadow carving line carving, etc., can also be processed on a few metal materials, the price range is related to the power of the laser tube.
