Buy CNC engraving and milling machine to pay attention to what

1) system: the most commonly used hair grid, Bao Yuan, new generation, and fine carving system. Fagor and Jingdiao system is better, mainly reflected in the finish and speed above. Bao Yuan and the new generation of 10A system is also good, it can be said that these two systems with more people than the hair of the grid, Bao Yuan and the new generation of the system after so many years of market testing enough to prove that it is a very good system, stability, processing results can reach the customer's requirements. Fag's main embodiment of the processing speed of complex surfaces, his corner processing speed is quite fast, Fag's shortcomings are slow after-sales, maintenance costs are high, general mold processing is not necessary to consider, such as filament molds too much to use the Fag's system to bend around, you can improve efficiency. New generation of service is the best of these systems.

Choose a system to be considered a master of the habit of use, the master has an inertia of thinking first which system, which system is good to use.

2) fuselage: this is more critical, the fuselage of the good and bad directly determines the effect of engraving and milling machine processing and accuracy of the good and bad. Carving and milling machine is not like a computer gong, can not use the thinking of the computer gong to do the carving and milling machine, so, Taiwan is the machining center bed in the market to do more hot, but the carving and milling machine bed not many people use, not his material is not good, the material can be said to be absolutely OK, but that is the concept of the wrong, the carving and milling machine to do the base of the solid, but the head must be light, so that the solid base can effectively Prevent the carving and milling machine high-speed processing brought about by the vibration of the light head servo motor can be controlled at will, you can gong out a very beautiful effect. The bed of the Taiwan positive is too heavy head, gong up jumping sound, really miserable, let a person is very uncomfortable, the effect is naturally not good. Castings in addition to the material to be good, there is a most important point is that all have contact with the surface must be precision shoveling, grinding with a grinder out of the stability of the absolute lack of artificial shoveling stability. Grinding machine grinding is face to face, while manual spade is point to point contact. To spade the place including the screw holder, column, column base, wire rail. Although some manufacturers also have shoveling, but in order to save time shoveling will also be jerry-building, such as guide rail must be shoveling the whole article together with the flower to be good, some only shoveling the two ends, I went to Jiangmen to do a milling machine factory has seen, they shoveling is the two ends of a shovel in the middle of the sanding machine with a hit, it's over, the whole rail two on the finish, and the master of the manufacturer's factory for the sake of the figure of efficiency, and at the same time, in order to meet the factory's one-tenth of the requirements, on the Speculation, directly with the screws to adjust, the screws tighten a little, that loose a little, so that the assembly process, although the factory can reach a trace, but with a little will change, this is a lot of engraving and milling machine is not durable one of the most important reasons, a lot of manufacturers to blow their own how much more than a small number of, then I ask you, your amount of how to ensure the accuracy of the assembly, some manufacturers say that they are how fast and how quickly to install a machine to show their own technology, how, then I ask you, how to install a machine? How, then I ask you, loaded fast how to ensure the stability of the machine. Screws are loose, talk about rigidity and where the stability. A light machine if the serious shoveling flowers to do if you want to 5-7 days. Doing a good job or these few, carved, Kejian, Lima, body assembly are real, not for precision and precision, must ensure the durability of precision.　These are strictly in accordance with the requirements of all shoveling surface accuracy of 1 silk to do, there are times when shoveling is not smooth, a machine shoveling on a two or three days is normal. However, only such a process, high requirements to ensure the quality of the machine.

3) Screw: good Japanese THK, Switzerland Schneiberger SCHNEEBERGER, Taiwan on the silver HIWIN or silver PMI with a good. Domestic workmanship is very rough without gloss, there are many surface scratch pattern, and Taiwan looks shiny, the surface of the line rail is very flat, and with a steel stamp on the silver or Yintai logo.

4) Bearings: Japan NSK, Germany FAG. Japan NSK fakes are too much, a little afraid, y afraid of a hit. Of course, to NSK authorized agents to rest assured.

5) to the knife instrument: Japan's Metro, absolutely good, to the knife precision 1U, stability, oil are doing a good job, good things to cherish, with the Metro to the knife instrument, to the knife to the end of the lid to cover immediately. Kejian, Lima, Jia Tie's are all Metro's. The self-developed ones of Jingdiao are also good. Fine engraving of self-developed equally good.

6) oil pump: Taiwan Hualeshi or Denmark Grundfos, this piece is seemingly less important place, but the oil pump is easy to bad pumping oil. Will also lead to downtime, everything will cause can not process the problem is a big problem. Good machine as a whole will use good parts, so there is this piece will not be ambiguous.

7) circuit breaker: Schneider or Merlin, the country before the domestic machining centers many manufacturers are using, and carving and milling machine with less, the cost is too high.

8) drive and motor: Japan's Yaskawa's good point, but also optional Sanyo, but the noise point. Yasukawa's now into the V system (i.e., 5 series), many manufacturers without technical strength said that the bad tune, V system relative to the 2 system is a fussy point of the body, the requirements of the body design is good, in order to play the advantages of the V system. At the same time, the V-series resident drive debugging also requires a high point, the drive is not well adjusted, the three-axis running, the commutation of the loud noise.

9) spindle: domestic spindle are about the same, this is a carving and milling machine is one of the biggest drawbacks, the domestic spindle maintenance rate is high, but the price is relatively cheap a lot of manual dismantling of the knife of the domestic in a few thousand dollars, more commonly used Star, Ronghua, Huadiao. Star's sales, Ronghua's expensive, solid workmanship. And Taiwan's spindle to be expensive tens of thousands of dollars. There are also brands with high-compatibility models with Taiwan's spindle, the price to 25 or so, such as the Ke 挻, Li Ma carving and milling machine. Li Ma's pneumatic spindle are standard with Taiwan's Pusen and Li Ma's own spindle brand LEADMA using imported ceramic ball bearings. Section 挻 higher-end useful Swiss BIG spindle, the price reached 400,000, fine engraving of the spindle of their own production. Select spindle depends on personal habits, economic strength, and use. If you want a tool magazine to choose pneumatic, choose pneumatic to buy a good point, the best not to buy the domestic, such as Star, China carving, Rong Yida spindle maintenance rate is too high, the spindle with a period of time the sound is too loud. General gongs, then, the choice of domestic manual is good, the biggest advantage is the maintenance is convenient, fast, low cost. For some people who just started a business to manual dismantling spindle is the first choice. In addition, the choice of spindle bearings also have to pay attention to, if the gong steel, speed can not be too high 15,000-18,000 on the line, the choice of steel ball bearings, more durable, open thick and powerful, Lima has a steel engraving and milling machine, the minimum processing speed of 2,000 rpm, you can open the flying cutter. This selection is the steel ball bearing. And more than 18000 rpm is not suitable for steel ball, too much heat, easy to burn off, bearings are easy to bad, on the 18000 rpm, you must choose ceramic bearings. Increase his durability.

10) Filter: This is also more likely to have problems with the link, it is recommended to use Taiwan SHAKO, or Taiwan ALLREAT, the latter is the former internal out to do, but are doing well. Fever level is SMC, generally only Japanese machine tools will use SMC pneumatic. SMC is the boss of the pneumatic components level of enterprises, of course, the price will make machine tool manufacturers look forward to. Note that there are installed pneumatic spindle engraving and milling machine to be sure to install filters, a long time easy to lead to water into the spindle caused by failure, domestic Utah to be installed, Taiwan's hydraulic removal of the knife, a little better. Gas is connected to the pressurized cylinder. Not directly to the spindle. But the air seal must also be filtered.

11) solenoid valve: Taiwan Adecco's good, but there are too many fakes, the difference is three times the difference in price. If it is in the roadside pneumatic store to buy, 80% is fake, must be to the designated agent, or branch to buy. You can check on the website of Airtac. Real and fake workmanship is not the same, the appearance may be almost the same, but there are differences in the internal air holes, the actual use of the difference is that the fake easy to break, the original less bad. Again, the SMC ones are very good.

12) Wire: Lysda, Golden Dragon Feather, Golden Huan Yu. We recommend Lysda's, which is generally reported to be thicker for the same specifications.

13) Also note that some manufacturers in order to save money, even a load switch are not willing to use, the load switch plays the role of the master switch. The price of a few hundred dollars or so. This is still to be equipped with a. Not only is the role of a switch, but also play a super-load automatic power-off function.

The following also try to recommend a few self-professed good machine tools, 600 machines as an example:

1. Beijing Jingdiao: price 20-45 million or so. The most successful domestic carving and milling manufacturers, with independent research and development of the control system and programming software, its processing relief, small knife road with unparalleled superiority. Widely used in the eye area, relief, jewelry, electrode processing. Its advantages of processing speed, processing workpiece beautiful, after-sales service in place. At present, Jingdiao has offices all over the country, Jingdiao is the only domestic machinery manufacturers without salesmen, but also the only one of the basic all cash transactions manufacturers, it should be said that is also the most sold a carving machine manufacturers, such an enterprise prospect is unlimited, the current price of 600 machines in the 290,000 or so. If there can be less than 200,000 machine 600 machine, I believe more people will choose Beijing Jingdiao. Now Jingdiao launched a new 600 machine with 15 tool magazines, automatic chip removal, the price of 46 million, the appearance of this machine has not changed much, with automatic chip removal, increased to 4KW spindle, can be gong to move the steel material. Independent of the price of things can compete with foreign brands, really bottom line huh. According to reason, to do so the scale of many enterprises are seeking to go public, but Jingdiao is not listed, have seen such a sentence, in China, money-making enterprises do not go public, do not make money to squeeze through the head want to go public. Listed after the circle of money away. From this point of view, Jingdiao is still a very socially responsible enterprise. Enterprises are really down to earth to do things. For the national manufacturing industry to contribute their strength.

2. Positioning of high-end, high configuration, general processing can not afford to buy, the machine sold to the factory more. Also do a small number of 100,000 or so machine (this type of machine with a domestic system). The machine's workmanship is good, in the customer has seen a 500 carving and milling machine, spindle is probably only a few hundred watts, mainly used to do the watch, the price is also sold to 195,000, ask the customer to use the situation, with a few years of stability is good, and occasionally there are some small problems, the phone inside the problem can be solved.

3. force horse carving and milling machine: price in 165,000 -23 million between the reason why the recommended force horse carving and milling machine, and not his fame, recommended force horse carving and milling machine reason indeed because of his workmanship is good, I've been to a lot of force horse carving and milling machine customers to its evaluation is very high, customers reflect the force horse carving and milling machine material is very willing to pay the capital, with the parts are Real goods, stability is good, the gong is also bright, after-sales service tracking fast. I looked at his machine as a whole, 600 machine weight in 3.2 tons performance in the middle of the road, but the design is quite reasonable, casting base to do quite solid, column width. Other details of the treatment is also quite in place. In the oil in place, wiring is quite standardized, neat. Finish relative to the Beijing Precision Carving to be a little worse, but for the carving and milling machine on the market is definitely good. Castings of all contact surfaces are shoveled flowers, force horse machine is made by the Taiwan force DEMA in the mainland, the Taiwanese do the quality concept than the mainlanders do have to be strong. LiDeMa machine 600 minimum configuration 165,000, high configuration Taiwan original high-speed spindle about 230,000 yuan. Power horse carving and milling machine did not do anything to promote, most of them are customers between word of mouth, visibility is not as good as the above a few. But cost-effective is the best.

4. Jia Tie Gaoke: price at 15-19 million. Good iron machine current market price of about 165,000, on time after payment can also get the corresponding rebate. Good iron machine market share is relatively large, many processing stores with good iron engraving and milling machine, engraving and milling machine may be too competitive, the money is not as good as before, good iron engraving and milling machine did not pay so much attention to the good iron is currently focusing on the higher profits of the high-lighting machine and PCB drilling machine, specifically how you can go to understand.

Said so much, I believe we have a certain understanding of the milling machine. If you want to summarize, simply put, so a few of the most important.

One, the accessories should be good. Including machine tools and key accessories

Two, the body should be good. Including the structural design of the body, casting materials, body parts materials, casting aging treatment, body assembly. The design of the body determines the grade and life of the machine tool. Good machine tools are not on the body up and down the hard work, in order to maintain such a long life.

Three, the system should be good. At present, you can choose between Fagor, Xindai, Baoyuan, of course, these are not the best, but the current domestic market utilization in terms of these kinds of is relatively good.

Four, the service should be good. Good service, good attitude, including pre-sales, sales, after-sales and after the warranty period.

Other brands: Hong Jinshun, Jingyi, light sinks, Jinfuli, Gao Cheng, Feihe, Tiangong, Sikai, Yiming, Guangcheng and so on too much. Want to buy a machine friends can press what I said earlier to choose, you can buy a good machine tool. Do not necessarily have to pick the most expensive, or pick up the cheapest, depending on your own needs, if you do hand plate or Bakelite and so on I think it is good to buy wide carving
