CNC drilling and milling applications News Summary: CNC drilling machines and CNC milling machine is an important equipment in the circuit board processing, the device is expensive, the choice of CNC machine tools, not only for the operation, process setup and maintenance, including for the production of quality products have a very important. Out of pure technical and operational aspects to consider as a process, the selection of indicators for CNC machine tools general from the following aspects: 1. The rigidity and stability of the machine table so that the machine has sufficient stability, many manufacturers have CNC drilling and CNC milling circuit board processing an important equipment to avoid rigid vibration, the device is expensive, selection of CNC machine tools, not only for the operation, the process setting and maintenance including important for the production of quality products has. As a craft out of pure consideration of the technical and operational aspects, the selection of indicators for CNC machine tools general from the following aspects: 1. Rigidity and stability of the machine table in order to make the machine has sufficient stability and rigidity to avoid vibration many vendors marble as the material of the bed, some Japanese manufacturers using steel to make the bed, the deformation of steel in different temperature than marble, unstable, manufacturers will be used in the software compensation to eliminate the deformation caused by the loss of precision. Most vendors are natural marble or artificial marble as a bed, we recommend using the equipment of the marble bed, marble maintenance usually use detergent and water to scrub, not with alcohol. Cawan later with a dry cloth, before they can complete evaporation of moisture such work. 2 two one for Rolling speed up to 80,000 rpm. Shaft speed and stability shaft, another air bearing speed up to 120,000 rpm. If the milling of Rolling its longitudinal bearer than air bearing drill chuck is procurement is the focus of the scope of the study, some of the drill chuck is not easy to replace and difficult to maintain, and some drill chuck wear quickly became consumables and replacement costs are expensive, some need daily maintenance of a waste of time. The shaft of the presser foot is another life and unreasonable design can also cause a lot of trouble, such as between the shaft and the presser foot seal resulting in cleaner procurement waste of money or the power of the central vacuum cleaner to be a great power caused waste, and is likely to produce the circuit board hole Paixie bad situation. 3. Countertops mobile precision and displacement Repeatability is the most important point of the selection, but also can not see through pictures or ordinary run only after the purchase has been certified by the test before the current equipment just factory can meet the design standard, the key is run after one to two years the accuracy is very stable, and the production machine in Europe do better in this regard. 4.X, Y, Z axis feed rate feed rate with the screw stepper motor, the speed of 25 meters per minute, while the new products have been used a servo motor, a high feed speed can productivity 20 % -40%, the speed of the Z-axis is influenced by the impact of the drill bit and the drilled material feed rate, not very big impact on production efficiency. 5. The countertops mobile and fixtures, countertops mobile hosts before many rail mainly also mobile bearer flotation as countertops, using the flotation countertops mobile flexible, and easy maintenance, procurement as the preferred. Fixed-line table plate of the device is generally air chuck, the chuck design an important impact on the future replacement of equipment, general requirements for easy to wear, due to one of the device there wear the most serious wear. Wear replacement and debugging simple, for machine positioning accuracy debug (do milling with template). There are many vendors provide automatic clamping device is best not to use if you do not have good equipment maintenance engineer, maintenance engineer requirements for automatic loading and unloading device high and the current circuit board drill sometimes more than one hour within general there is no need to choose. Maximum processing size of the largest processing size is needed to purchase most of the machine tools can meet your needs, in addition to some uniaxial or biaxial machine is used to sample or production test fixture. 7 operating system and control system now adopted in many machine common windows operating system interface is very friendly, and some also use the Chinese, it was easier to get started learning and operating stability of computer viruses but its shortcomings will be somewhat less and management more difficult, the industrial system or Unix systems, the advantages of the system is good stability, the fault is not easy, and easy to manage. The operator interface is in English, the operation started slower. Recommend the use of the latter from the perspective of technology and equipment maintenance. 8. Less machine tool of the tool management system some eight tools folder, most of CNC machine tools can be placed now hundreds of drills, some systems also automatically detects the broken drill diameter detection degree and radial beating system should pay attention to the items in the selection of the time is most CNC drill bed on the front end of the mesa, has a drawback in that the design embodiment, if the processing circuit board in the work due to fixing problems jump escaped easy to bash all drill, drill jig. Some drill on the machine above the fixture design, as part of the Swiss production machine will not have the problem, too high and too low of detection sensitivity of the machine is not good generally low point. 9 foot light system buy most of the measurement system of the CNC machine tools are used light feet as location and precision measurement feedback system, magnetic tape, using light foot system stability and high resolution, due to the light feet read head ruler no contact friction, so long-lived, but usually to keep the equipment clean to minimize dust pollution. 10. Dust collection systems, such as the company does not have a central vacuum system using common industrial cleaner power as a supporting pay attention to cleaner power, the best than the original design needs large 30% -50%, in the actual use of the process. due to filter clogging power will drop a lot, followed by the cleaner the powder bags have enough capacity, if the capacity is too small to make the workers often work stoppage to deal with dust to affect production efficiency. 11. Protection system encountered an unexpected protection system designed to prevent the occurrence of accidental injury and the device itself, such as raster protection infrared protection air switch on the device software and equipment, etc., such as infrared protection needs rational design some protection design maintenance is not very convenient. So you want to evaluate. Relatively recommend purchasing equipment manufactured in Europe, such as Switzerland and Germany, although the price may be slightly higher but the value for money of the production of machine tools than Japan, and future maintenance costs more reasonable and less problems, use a long time. As a personal point of view, a company history that can not be recognized by the people or countries, has been signed on a small contract commitments within the contract history and how to ensure it can be said?
