How to choose a CNC cutting machine
- Choose the type of engraving machine according to the material you are engraving. 2. Choose the size of the engraving machine according to the size of the material to be processed. 3. Choose the structure of the engraving machine according to the weight of the material to be processed. 4. Choose the accuracy required to be processed. Choose the transmission mode of the engraving machine. Classification of engraving machines: The general categories are divided into advertising engraving machines, woodworking engraving machines, stone engraving machines, and laser engraving machines. Choose the structure, type, and transmission method of the machine you need based on the above four perspectives. Engraving machine transmission mode: Currently, engraving machines are divided into three transmission modes, screw drive, rack drive and synchronous belt drive. Advantages and Disadvantages of Screw Machine: Screw transmission is the transmission method when engraving machines originated. It has high precision, slow running speed, high environmental requirements, and relatively short service life. The Y-axis single screw is not easy to be too long (the model cannot be too long). Large), it is easy to shake when running at high speed. If the installation accuracy is not high, the Y-axis screw may be broken when running for a long time. If the accuracy is too high, a Y-axis double screw structure can be used to meet the requirements. The general processing speed is about 7 meters. (Mainly suitable for advertising, wood products, small handicrafts, and lighter stones. Any carving material can be processed according to different tools)
Advantages and Disadvantages of Rack Machine: Rack machine is an upgraded version of screw machine. It is a newly developed model because screw machine cannot meet the requirements of high-speed processing. It is fast and does not have harsh environmental requirements.
It has a relatively long service life and lower precision than a screw machine. The Y-axis and X-axis of a rack machine are driven by a rack and pinion, and the Z-axis is generally driven by a screw. The accuracy requirements are mainly determined by the meshing accuracy of the guide rail and the rack and gear. The size and length of the machine can be large enough and it is easy to maintain. It is generally equipped with a manual oiling system. It is recommended that the processing speed can reach about 15 meters. (Mainly suitable for processing woodworking products, cutting paint-free doors, cabinet doors, solid wood doors, screens and other panels, hollow reliefs can also be processed for advertising, stone, marble and other materials, depending on the tool selection)
Synchronous belt drive: Synchronous belt drive is mainly used in laser engraving machines and plasma cutting. It has the characteristics of light weight, high precision, easy maintenance, and easy to relax over time, affecting processing accuracy. (Laser machines are mainly used in the advertising industry, handicraft engraving, cloth, leather, glass, stone, crystal and other non-metallic materials for shadow engraving and line engraving. They can also be used for processing on a few metal materials. The price range is related to the power of the laser tube) Introduction to drive system: (Jinan Pinmai CNC) At present, the drive system of engraving machines is mainly divided into two categories: stepper system and private server system. The stepper system occupies a major position. This is because it is economical and affordable and can meet the requirements of general customers. Stepper system The system is a semi-closed loop system. The accuracy is calculated based on the step angle. The private server system is completely in the closed loop mode and has a measurement feedback system, so the accuracy is relatively high. Customers with large power, stable operation and higher requirements can choose machines with private server drive systems (the price is slightly higher). expensive). At present, there is also a semi-private server system on the market, which is an improved version of the stepper system. Please pay attention to this when choosing a machine. Jinan Dimai CNC
