The cutting energy of the cutting machine has been developed from a single flame energy cutting to the current multi-energy cutting method; the CNC cutting machine control system has been developed from the simple function, complex programming and input methods, and the degree of automation to a perfect function. Intelligent, graphical, and networked control; drive systems from stepper drives, analog servo drives to today's all-digital servo drives. The laser cutting machine is the fastest, the cutting precision is the highest, and the cutting thickness is generally small. The plasma cutting machine also cuts quickly, and the cutting surface has a certain slope. The flame cutter is designed for carbon steel with a large thickness. First, the working principle of the cutting machine The cable is normal, the protection and grounding is good, the protection device is safe and effective, the saw blade is selected to meet the requirements, and the installation is correct. After starting, it should be operated at no load, check and confirm that the saw blade is running in the correct direction, the lifting mechanism is flexible, and there is no abnormality or abnormal noise during operation. The operator should press the workpiece tightly with both hands and feed evenly. When pushing the cutter, do not use excessive force. Do not wear gloves when handling. The thickness of the cut shall be in accordance with the factory regulations and shall not be cut thick. When the workpiece is sent 300mm away from the saw blade or when cutting small pieces, it should be fed with special tools, and should not be directly pushed by hand. When the workpiece has impact, jump and abnormal sound, stop the inspection immediately, and then continue the operation after troubleshooting. It is strictly forbidden to inspect and repair all parts during operation. Debris on the saw table and in the kerf of the component shall be removed in time by special tools and shall not be picked up or wiped by hand. After the operation, the body should be cleaned, the saw blade should be dried, the remaining water in the water tank should be drained, the cable should be taken back, and stored in a dry and ventilated place. For cutting of mild steel, stainless steel, aluminum and other non-ferrous metals Second, the application of cutting machine Special-purpose CNC cutting equipment, contact and non-contact non-metal special CNC cutting equipment will also have a large space for development, and the entire CNC cutting machine market will continue to expand. Improve the production efficiency and cutting quality of CNC cutting machine, reduce the production and use cost, improve the automation level and system stability of the whole machine, and improve the system function to become the direction of its technology development. It is suitable for cutting the cylindrical orthogonal, oblique, eccentric and other phase-in-line holes, square holes and elliptical holes on various pipes, and can cut the phase line intersecting it at the end of the pipe. This type of equipment is widely used in the production of metal structural parts, power equipment, boiler industry, petroleum, chemical and other industrial sectors. Third, the characteristics of the cutting machine Under the premise of satisfying the cutting precision, we can talk about the speed. Because the cutting platform is short, it is difficult to judge whether it reaches the highest speed with the eyes. We can use the software simulation function of the servo drive of the cutting machine to check whether the motor speed is reached. highest. When testing the cutting speed, there is no need to cut the speed to increase the acceleration and deceleration. Each axis can be tested separately or simultaneously. Do not equip the I/0 signal and the mechanical sensor. The unnecessary switches and indicators should be as small as possible. Once a certain device on the machine fails, it will affect the use of the cutting machine. There are also fewer lines for easy troubleshooting and replacement of components, and it is best to debug the status of each I/O signal on the screen. Maintenance costs are an important factor that must be considered when purchasing a machine. Foot of ningxia hong xingda incense Organic Apple fruit suborbicular, fruit surface color yellow green, most with orange chardonnay fruit surface, covered with bright red stripes, pulp yellow-white, succulent crisp, sweet, rich fragrance, quality first-class; The fruit has a sugar content of over 15%, more than 4% of the national average, and the flesh is tight and crisp and sweet, which is widely loved by consumers all over the world. There is a longer optimal consumption date than any other apple, not even refrigerated. It can be kept for 4 months at normal temperature. If refrigerated, Fuji can be kept for 5--7 months. Wild Apple,Juicy Apple Fruit,South Mountain Apple,Natural Sweet Fruit Ningxia hongxingda fruit industry , http://www.hxdfruit.com
Altitude: high altitude area light, clean air, environment close to original condition, no industrial pollution. With an average elevation of 1160-2900m, the central health center has a strong uv light, which produces the natural pollution-free apple, which conforms to the concept of a modern green diet.
Temperature: moderate temperature can avoid the chance of fruit tree encountering disease. The average temperature in ningxia is 8.4 degrees Celsius, which has an important influence on the growth, development, yield and quality of apple. The piedmont apple is thriving in such a good environment.
Humidity environment: moderate amount of rainfall provides necessary conditions for apple's growth. The annual rainfall in the central health region is 186 millimeters. The fruit is slow to grow and the fruit is hard and hard, which fully guarantees the fruit's sugar content and the relatively average size of apples.
Sunshine condition: apple is the fruit tree, the central health area of the whole year is nearly 3,800 hours, is beneficial to the Apple Fruit coloring. The piedmont apples are red and bright.
Temperature difference factors: ambassador apple nighttime respiration weak temperature gap between day and night, consume less organic matter, the accumulation of organic matter during the day more, that apple store down a large number of glucose sugar candy, etc have better taste. The average diurnal temperature difference between apple and apple is 14 degrees centigrade, and the larger diurnal temperature difference ensures the sweet and delicious characteristics of the apple.
Other factors: frost can make apple blossom and fruit, which can cause frozen flower jelly, which is bad for apple's production. The piedmont apple has been kept at least 167 days without frost for the whole year, which minimizes the influence of apple on yield and quality.
