1. When choosing the type of CNC machine tool, you should first determine the technical requirements and process specifications of the products that the company needs to process, and determine the type of CNC machine tool according to the needs of the process flow and rhythm of the production line. There are many types of CNC machine tools. Only the correct type can be selected. Only then can the CNC machine tool play its best role and achieve the best performance-price ratio.
2. When choosing a CNC equipment manufacturer, the scale, size and technical strength of the manufacturer are closely related to the ability of the CNC equipment’s performance to operate properly. Unreasonable selection of manufacturers will lead to many inherent defects and unreasonable aspects of the equipment, which cannot be understood at all by consulting the equipment instruction manual or examining equipment samples. Sellers and manufacturers always choose the different advantages of the equipment to present. customers. The key point to pay attention to is that CNC companies in Taiwan establish themselves very quickly and close very quickly. Sometimes it even happens that the equipment has been closed and there are still promoters selling it. If you do not pay attention to these problems, the machine tool will fail when receiving delivery and during the warranty period. The manufacturer went bankrupt, and after the equipment was operating normally, it broke down and could not be repaired. The manufacturer was unable to honor the one-year warranty period. At the same time, such a factory must have incomplete original data and maintenance data for various equipment, and it will be difficult for users to repair them themselves. Therefore, when choosing a manufacturing company, try to choose a well-known manufacturer.
3. Choose equipment from well-known brands and well-known brands. Among the many CNC equipment manufacturers in Taiwan, many CNC equipment manufacturers with certain strength have their own famous products. For example, a single specification of CNC lathes produced by a certain factory is a high-quality product that has won the title of famous brand. The performance of other lathes cannot be compared with that of CNC lathes of this specification. However, in order to increase their market share and competitiveness and achieve higher profits, some manufacturers and promoters take advantage of the weakness of mainland enterprises that do not fully understand the production situation of Taiwan’s CNC equipment to promote types of CNC machines they never produced. to the mainland procurement companies, in this way, the mainland procurement companies originally needed a certain business. Famous brands of CNC machines are actually purchased as counterfeit products, that is, CNC equipment of different specifications from the same manufacturer. Such CNC machine tools often produce many design defects, resulting in lost equipment investment for mainland users. Many unnecessary and insurmountable gaps occur. when it comes to production. This is one of the main reasons why many purchased equipment cannot be used properly and remains unused.
4. Choose the system used by the CNC equipment. So-called system selection usually involves choosing a system from a relatively well-known brand, but this is not the key. The key lies in the CNC equipment factory’s ability to grow and expand. apply the system itself. Since many systems now have quite comprehensive functions, manufacturers set certain prices for various system functions (except common functions). This means that the purchasing company does not fully understand the functions of the system and does not request them when purchasing. Equipment. If the requirements for various system functions are met, the manufacturer will only provide commonly used general functions. When missing functions are found upon delivery, the manufacturer will submit a request to the manufacturer. , the manufacturer will have to pay extra to purchase it due to intellectual property rights. Some manufacturers have not developed this function themselves and will refuse to provide the function based on the contract content, which will cause users to fully play the game. The superiority and efficiency of CNC machine tools have great limits when selecting a system, system application and function development capabilities of CNC equipment enterprises. When negotiating, users should fully put forward their requirements for system functions, so that the equipment can fully operate. At the same time, they can also get multi-functional CNC equipment without spending a penny more if the company purchased Taiwanese machine tools. , this will certainly be the case. When adding a function, the price will be increased and the function will be offered as a friendly gesture at the end of the negotiation, but remember that this function should have been included when purchasing the machine tool. .
5. Various original data and necessary maintenance data of the equipment. Before reaching a final agreement, the supplier must provide various original data and maintenance data for CNC equipment. By studying and understanding this data, you can have some understanding of the manufacturer’s production capacity and design capabilities. work, it will cause a lot of unnecessary trouble once the equipment is put into production. Since the random data of Taiwanese CNC manufacturers is affected by the manufacturer’s design capabilities, it is generally not very complete. Some companies are relatively comprehensive, but they will not provide relatively complete equipment and maintenance information to mainland purchasing companies. Therefore, before purchasing equipment, we must fully understand all the information about the equipment. Generally, the information included in CNC equipment is:
1) User Instruction Manual;
2) Programming instruction manual;
3) Exploded view of the mechanical structure;
4) Powerful electrical diagram and detailed arrangement diagram;
5) Schematic diagram of weak current structure and detailed arrangement diagram;
6) Hydraulic schematic diagram and detailed hydraulic distribution diagram;
7) Schematic diagram of the cooling system and detailed distribution connection diagram;
8) Schematic diagram and detailed distribution layout diagram of the lubrication system;
9) Schematic diagram of the spindle cooling system and detailed diagram of the connection layout;
10) PC diagram of the equipment;
11) Equipment system user manual and maintenance manual;
12) Various parameter setting methods and spindle parameter setting methods, as well as parameter uses;
13) Equipment debugging methods (including mechanical and electrical);
14) Layout drawings of various sensors, detailed lists of electrical components and detailed lists of various consumable parts;
15) Solutions to common faults;
16) Instructions, user manuals and detailed electrical machine information for various purchased parts.
If a CNC manufacturing company can fully own the above correct information, it should be said that this company has quite mature design and process capabilities for each system interface, which can fully guarantee that the equipment is put in normal production and provide a strong guarantee for the normal use of the equipment.
After making the above selections, it enters the delivery phase. This step is very important for users, because users have entered the stage of actual contact with the equipment and can have a correct understanding of the accuracy and performance of the equipment. During the transfer process, some users did not know enough about the situation of CNC manufacturing enterprises due to insufficient preliminary preparations, and they were not clear about the after-sales service situation and whether the random information was complete and correct. At the same time, during the delivery process, the accuracy of the original machine tool data was not checked in detail, and the delivery note was signed after passing a series of accuracy tests. This will cause heavy irreparable losses to the user, because signing means that the user recognizes the equipment and terminates the entire purchase contract.
According to the CNC equipment made by Taiwan CNC equipment manufacturers that I have been in contact with in recent years, it is basically impossible to provide completely correct and complete technical information. Some companies can only provide drawings and information for part of the system. , and often the supplied systems Drawings and technical information do not match the machine tool itself, technical conditions and system drawings, so detailed checking must be carried out during the delivery time. Incomplete, non-compliant and missing information must be reported to the supplier. Do not sign the delivery note before receiving a clear response from the supplier. Pay. Pay attention to the correct method for requesting the missing information from the supplier, but this must be within the claim period when the contract is valid.
CNC equipment will encounter various faults during use, but every time a fault occurs, the CNC equipment will not be able to operate. If the technical data and maintenance data are incomplete or wrong data appears, misdirection will occur in the fault handling process. , causing the damaged or irreparable fault to expand. Random accessories must be fully inventoried according to the technical item and quantity requirements stipulated in the contract. If they are not complete, they cannot be signed at the same time; the supplier is required to complete them within the time limit stipulated in the contract. contract. Do not be under any illusions, do not be fooled by the supplier’s rhetoric and do not be moved by empty promises. Accordingly, the supplier will withdraw as soon as the legal limitation period has passed, and it will not do so again. be able to respond to all reasonable claims you have made. No matter how you approach it, the supplier will ignore you. Therefore, for the entire process of concluding the CNC equipment purchase contract, the buyer can only sign after the static and dynamic precision, accessories and other information of the CNC equipment have been fully and properly satisfied the buyer’s requirements. At the same time, it must be completed within the current limitation period provided for by contract law. If the contract limitation period is exceeded, no request for compensation may be made to the supplier. The user must therefore not give it up. weapon to legitimately defend their own interests.
The free maintenance and repair period for Taiwan CNC machine tools is one year after machine delivery. During this year, the provider will provide services to users completely and unconditionally. How to properly and reasonably use the warranty period is very important for users. Proper use of this year is very important for users. Normal use of CNC equipment is of great help. According to the practice of recent years, CNC. The frequency of equipment failure is closely related to service life. At the same time, the types of breakdowns are also different. Calculated based on equipment operating 16 hours per day, types of failures in the first year are usually caused by. the system itself, parts, component failures and unreasonable assembly of equipment. Failure of damaged parts and partial failure of equipment with congenital design defects. In other words, equipment defects with inherent design flaws will be exposed within the first year. The second and third years are the best periods to use CNC equipment. During this period, if the defects caused by human factors are generally eliminated. no defects. After three years, CNC equipment is in a period of natural wear and tear. The defects that occur are mainly those caused by easily damaged and consumable parts. At the same time, there will also be overall failures caused by the loss of some basic parts.
Based on the above estimation, it is better for users to allow the equipment to operate at full load during the warranty period, trying to expose all congenital defects of the equipment in a period of one year and let the manufacturer resolve them, so that the user can get a fundamentally excellent machine after the warranty period. For the equipment, during the warranty period, users must have their own trained CNC equipment maintenance personnel. When employees mature, in addition to special training before the equipment enters the factory, they also need to carry out actual operations. This one-year warranty period is the best step to become familiar with the equipment and how it actually works. of the equipment during the first year, the performance, component installation locations and operating conditions of the system, and become familiar with their interconnection relationships.
The company’s maintenance personnel must dare to deal with various faults that they have never encountered during this year. During this period, if the defect is resolved and experience has been accumulated, it does not matter if the defect is not handled well. manufacturer to repair it. Maintenance personnel trained by users themselves must actively cooperate, learn with an open mind, and absorb what they do not understand from the materials. Within a year, after several such processes, the CNC equipment maintenance personnel trained by the company will be able to shoulder the burden of ensuring the normal operation of CNC equipment in the future. Therefore, it is very important for users to know how to use the free warranty period correctly and reasonably. If you use it correctly, you can save a lot of money. On the contrary, large amounts of money must be spent to ensure the normal operation of CNC equipment. At the same time, because some Taiwanese CNC equipment companies do not have maintenance offices on the mainland, it will lead to long and high maintenance cycles. maintenance costs and cannot guarantee normal production.
In summary, various problems that may arise during the period of purchase, delivery and maintenance are explained in detail, necessary explanations are given for users to use their rights correctly and reasonably, and instructions for users to use Normally CNC equipment are more detailed data. preliminary preparation work. If these issues are not handled well, it will cause great losses to the country and users. It may even happen that the purchased CNC equipment cannot play a role in the production of the user’s products, rendering it idle.
