1. How To Choose A Right CNC Router? Some customers want to buy a CNC router machine, but they don’t know where to buy a CNC router, what parameters should be pay attention to, how to adjust whether the performance of the CNC router machine is good or bad, and what brand of CNC machine is good. The first thing that must be corrected is that we can't say which brand of CNC is good, but only which brand of CNC is more suitable for you. The application, performance and price of different brands of CNC routers are different. The higher the general configuration of the CNC machine, the higher the performance, the higher the engraving requirements that can be achieved, and the wider the field of application. If you must ask which brand of CNC is good, I suggest you choose a brand with high visibility and good reputation, like STYLE CNC Router, relatively speaking, the service is guaranteed and the quality is guaranteed. Having said that, as long as the configuration can meet your engraving requirements, there is no need to purchase a higher configuration, more expensive CNC router, that is, to choose one that meets your requirements and is suitable for your CNC. Five points to choose mechanical CNC router:
2. First, selection of format size. Customers should choose the CNC model and its power suitable for their own needs according to the business needs and financial situation. Generally, small-format CNC routers have 600mm × 600mm and 600mm × 900mm, and the feed width is 700mm. Engraving two-color plate is the most basic application of small format CNC router, and its acceptance is very good. The price of a smaller CNC router is similar to it, but cutting the board when engraving the two-color board is more troublesome and causes unnecessary waste. The large-format CNC routers are 1200mm × 1200mm, 200mm × 1500mm, 1500mm × 2400mm, 2400mm × 3000mm. The engraving width of the CNC routers of the above models are more than 1350mm. The sizes of plexiglass and PVC plates on the market are 1300mm × 2400mm, so these models are more suitable for customers who need large-format CNC routers. Second, the spindle motor. The spindle motor is an important component of the computer CNC router, and its performance has a crucial influence on the performance of the computer CNC router. Machining spindles are usually divided into two categories: precision machining spindles and high-power cutting spindles. 1. The characteristics of the precision machining spindle are low noise, high speed, and height, which are suitable for processing particularly delicate workpieces, such as seals, nameplates, badges, gifts, etc. This type of motor is usually a high-speed variable-frequency motor with low power, generally below 250W. The disadvantage is that the ability to cut thick materials is poor, and it is not suitable to cut thick materials. 2. The high-power cutting spindle is mainly used for cutting and high-power engraving. It is characterized by large power and strong cutting ability. It is especially suitable for cutting Yu and three-dimensional characters. Of course, it can also make badges, nameplates, seals, etc. Such high-power spindles can be generally divided into brushless frequency high-speed AC motors and brushed AC motors according to the characteristics of the motor. The main differences are: A. The speed of the brushless variable frequency motor is high, and the speed range is 70060000 rpm, while the maximum speed of the brushed AC motor generally does not exceed 24000 rpm B. The brushless frequency conversion motor has high rotation accuracy, low wear and low noise, and the operating noise is much lower than the brushed AC motor; C. The brushless variable frequency motor has good stall blocking characteristics. Due to the special current limiting circuit on the inverter, the short-term stalling will not burn the motor, and the brushed AC machine will quickly smoke when it is overloaded or stalled Burned out and cannot be repaired; D. Brushless frequency conversion motor adopts frequency conversion control technology for speed regulation. It is a professional-grade product with a long life. The manufacturer provides 1 year free replacement. In the future, the motor can be maintained by replacing the high-speed bearing. The life of the motor or motor carbon brush must be replaced in about 300 hours, so the carbon brush AC motor is usually not guaranteed for one day. Third, choice of control method and speed. The control methods can now be divided into three types: A. All the calculation work is controlled by the computer. When the CNC router is working, the computer is in the working state, and other typesetting work cannot be carried out. This may cause the wrong operation of the computer and cause waste products. B. Using the control of the single chip microcomputer, this controller can perform typesetting while the CNC router is working, but it cannot turn off the computer. This is actually equivalent to saving 7 computers, and reduces the waste caused by the misuse of the computer. C. The USB port is used to transfer data. The system has a memory capacity of more than 32M. As long as the file is saved, you can immediately disconnect from the computer, shut down the computer, or perform other typesetting. This way greatly improves the working efficiency of the CNC router.
3. Fourth, guide rail. Large-format CNC routers must use widened imported square guide rails, whose load capacity and precision retention capacity are more than 30 times that of round guide rails, ensuring high- quality and high-speed CNC routers. Fifth, precision. Small format machine engraving 1mm Chinese characters, or large format CNC router engraving 1.5mm small characters, should be very clear under the magnifying glass. Purchase guide for mechanical CNC router. 1. Clarify the nature of work. Don't think that buying one CNC router can do all the work. The manufacturers divide the CNC routers into various specifications and models in order to deal with various processing tasks. For example, if you buy a mold CNC router to engrave the two-color plate, or buy a large CNC router to engrave the seal, this will cause a huge waste and will not achieve good results. Similarly, if you buy an advertising-grade CNC router to make molds, you may not be competent at all. So before you buy the machine, you must fully explain to the sales staff what you need to do, including the size of the workpiece, the material material, the thickness and weight of the material, the final engraving effect and requirements, and so on. 2. Choose the right model. For the first time, the small advertising signboard shop purchases the machine, mainly for the production of three-dimensional character lights, crystal characters, double-color plates, badges, etc., it should be purchased at the advertising level, but it should be further refined in the configuration of the machine, such as mainly making double-color plates , It must be equipped with a floating cutter head, because it can ensure that the lettering is consistent when engraving on the large-format two-color board, but it is mainly used to saw plexiglass crystal words, it is necessary to choose a high-power spindle above 800W. Otherwise, long-term heavy work with a low-power and high-precision spindle will accelerate bearing wear and lose accuracy. Generally speaking, the CNC router format is larger than 600mm, and it is not suitable for engraving two- color plates and other delicate work, and it is suitable for sawing and making some large flat cards. The CNC router with a width of about 600mm is a general-purpose CNC router, which can be used for fine work such as double-color plates and rough work for sawing. For the processing of cylindrical surfaces or other special-shaped workpieces, due to the need to install some jigs or rotating coordinate axes, this will show the height of the Z-axis column, and the space between the table and the cutter head is large, so a special machine can be used. If the seal shop specializes in engraving seals, it can be equipped with a seal CNC router first. The laser CNC router for engraving leather stamps and atomic seals is the best, while the stamps for materials such as bronze stamps, jade stamps, and horns are 6090. If the two are combined, all kinds of materials are common. 3. Trial carving before purchase. Before purchasing a CNC router, in order to ensure the return of your investment, you should let the sales staff or you do it yourself, and try to carve the most common work you do. Simultaneously calculate the ergonomics, observe the effect, fully test the performance of the machine, and really know what you want. 4. Sign a contract. After deciding to purchase, the first thing to do is to sign a contract with the seller. The contract should indicate the purchased model, configuration, price, delivery time and delivery method,
4. training method, warranty terms, and payment methods. After the contract is signed, usually a certain deposit (except those in stock) should be paid according to the contract. 5. Delivery and training. After the CNC router arrives, the technicians usually come to the door for unpacking and inspection. After the power is turned on, you should carefully check whether the appearance is damaged and whether it is damaged by impact during transportation. If it is intact, then check the random accessories of the machine configuration according to the contract manual. The technician installs the machine (including hardware installation, removal of fixing parts, placement of the machine. Connect the power supply Use various cables. Software installation, configuration of computer, installation of optional carving software). After the installation is complete, engrave the machine with the test chart file provided by the manufacturer. If the engraving test is completed correctly, the delivery inspection is completed. According to the contract, the user should pay the balance. The customer's operator requires a technical secondary school degree or above and a proficient computer operation foundation. It is best to have experience in the operation of a cutting plotter. It is much easier for users of the Roland plotter to learn the Roland CNC router. In the training process, you should master the selection of different engraving speeds and the use of different tools for different materials. This aspect often requires the accumulation of experience and good mastery, which is good for extending the life of the machine and the tool. 6. Problems that may arise during use and after-sales service guarantee. I. Use environment. The CNC router is a high-tech mechatronics device, which has certain requirements on the working environment. A. Avoid equipment that seriously affects the signal transmission of the CNC router, such as strong electricity and strong magnetism. Such as: welding machine, launch tower, etc. B. Use three-core power supply to ensure good grounding of the CNC router and reduce interference. C. Voltage requirements are stable, to avoid large fluctuations, it is best to use a voltage regulator. D. The machine can not work for a long time in the environment of strong acid and alkali. II. Care and maintenance. The CNC router is mostly used for processing business, and the powder and dust generated by processing are more. During use, pay attention to keeping clean and lubricated parts such as screw rods and polished rods, and clean up the dust and oil to the transmission parts in time; the operator should clean and lubricate in time. III. Software usage problems. The CNC router has many engraving software available. Such as: Casmate-pro, Caxa, Mastercam, Artcam, Smartcam, Type3, etc., in order to meet your engraving requirements, please select the correct operating software. IV. Processing issues. A. The rationality of the processing technology. In addition to the CNC router to ensure the processing accuracy, reasonable processing technology is also very important. In order to ensure the accuracy of the processing, please pay attention to the rationality of the processing technology. B. Tool use. Because the manufacturing process and precision of the tool itself affect the machining accuracy. Therefore, please select a tool suitable for machining during machining. C. Operator.
5. The proficiency and sense of responsibility of the operator also have a great influence on the machining accuracy. D. Machine wear. The wear of the CNC router is inevitable during use. With the use of time, the wear of the machine will reduce the accuracy of the machine.
