1. The eccentric spoil of the eccentric axis abroad is large. When cutting large materials to cutting small materials, it is either to change the knife pad or the blade, and sometimes the conversion angle needs to be changed.
2. The racks of foreign cutting machines are steel plate welding structures. The processing accuracy and roughness of the components are excellent, especially the heat treatment process is strong, so that the cutter exceeds the domestic machines in terms of overload, fatigue failure, and wear.
3. The design of the blade of the domestic cutting machine is unreasonable, the single bolt is fixed, and the thickness of the blade is thin enough. The thickness of 40 and 50 blade is 17mm. Comprehensive performance and other comprehensive performances are better than domestic.
4. The number of domestic cutting machines is small per minute. The domestic domestic is generally 28 to 31 times, and foreign countries will be 15-20 times higher, up to 30 times, and the work efficiency is higher.
5. Foreign models generally adopt a semi -open structure. Gear and bearings are lubricated with oil. The crankshaft axis trail, connecting rod tiles, punching blade, and rotor are manually lubricated by hand. There are three types of full, semi -open and semi -closed, and the lubrication method has two types: concentrated oil lubrication and splash lubrication.
6. The appearance quality of the domestic cutting machine and the performance of the whole machine are not satisfactory. Foreign manufacturers are generally large -scale production. They are willing to invest in technical equipment. The level of automation production is high, forming a complete quality assurance processing system. In particular, the quality of the appearance is excellent. The outer cover is one -time stamping and forming. The paint is sprayed by the paint. The color is scientific and reasonable. Although some domestic manufacturers have a long history of production, none of them have formed a scale. In addition, the equipment is aging, the processing process is hard -working and experienced, and the production process has been consistent for decades. Therefore, the appearance quality is rough and poor.
