A different angle, a different harvest
One thousand people have one thousand Hamlett in their eyes. The same things are different in nature because of their different perspectives and views. Of course, the thing itself is, of course, the situation of the audience.
Mining of thin coal seam coal mining industry is recognized as the "chicken ribs", without allowing technical support and equipment is in good condition under the safety in many mining this is only wangyangxingtan.
Thin coal seam mining is difficult and low input and output, which makes developers very helpless, but can only be shelved, but this is not the best measure. There is a hidden danger in the thin thin coal seam. But more than 85% of the mining areas in China have thin coal seams, and the estimated amount of mining can reach about 6000000000 tons. As a result, the "chicken ribs" have become the reality that we have to face, but it is hard for no special mining equipment, so the actual progress is not smooth.
Bottleneck of research and development
The difficulty of mining technology for thin coal seam is mainly due to the lack of special equipment in this field, so the market demand and development space are attractive. So the 31 reload set up the determination to make the world-class thin coal seam coal mine equipment.
Comprehensive domestic coal seam status and customer demand, comparative analysis, and constantly improve the design ideas. Finally, the company has developed the first 400B series shearer's formal downline for the mechanized coal mining equipment that is suitable for the extremely thin coal seam.
In 2014, 400B won the identity of thin coal seam customers with the perfect and stable mining performance. The high adaptability and reliability of the 31 reassembly 400B series shearers is the pioneering work of thin seam fully mechanized mining, especially in the bottom part of the shearer, and there is no failure in the production of the whole working face for 8 months.
Compared with similar products at home and abroad, 400B series shearers have advantages of lower and shorter fuselage, larger cutting density on front cutting head, and higher automation and intelligence. At the same time, the 400B series shearer also cites the structure of automatic supporting slipper device to further improve the adaptability and anti vibration capability of the equipment.
But before its product line, Shenyang 31 reloading in the fully mechanized production workshop also encountered many difficulties. For example, the deep cavity / deep hole processing of the casting shell is one of them.
It will save half the time
According to the process of the previous 31 heavy motor rocker shell rough boring holes often need more than three times to complete, while the operator needs to manually adjust the rough boring holder of more than two times, and then use the face milling cutter hole bottom. With the increase of the axial extension of the spindle, the tool has large vibration, low machining efficiency and long processing time. When the vibration is serious, it will be more likely to damage the tool and even damage the machine tool.
When the 31 zone reflects this issue to the tool partner iscar, application engineer iscar for the first time arrived at the scene processing, in the full analysis and research of the processing problems, make quick response to the feedback to the Dalian Department of technology. The expert technical department to optimize the rapid iscar processing solutions to customers.
The advantage is not only reduce the plunge milling tool / knife body damage frequency, and with a knife at the same time to complete the roughing milling insert Hexi bottom cut step. A substantial increase in tool life at the same time, the solution provides effective iscar, saves processing time 50%.
The right choice
In fact, this is only a case in the process of successful cooperation between the two sides. In early 2009, with the help of 31 complete reinstall the processing problem of electric control box shell and the rear supporting part of roadheader, iscar began working with the 31 reload.
Then with the boring cutter, reamer, iscar face milling, milling cutter, milling cutter square shoulder different products in 31 heavy mark, combined with its excellent performance and good service for customer service, after becoming a high quality strategic partner 31 ISCA group has laid a good foundation for cooperation.
In addition, the excellent performance by the Shenyang 31 heavy use of iscar on roadheader, step by step in scraper conveyor, hydraulic support, shearer full use of iscar.
At the same time, it also set off a storm in the 31 Israel tool group, Shanghai 31 machine and 31 science and technology, Beijing 31 machine and 31 Changsha electric, Sany, Loudi ZTE hydraulic, are increasingly using iscar company's products, DR shallow hole drilling, gun drilling, chameleon drill the spiral blade, tool, King iscar knives and other products, more and more customers are familiar with. Iscar gradually by using the original coal machine parts manufacturing, machine tool manufacturing expanded to parts, engineering machinery, hydraulic cylinder etc..
Iscar engineers several times together with Shenyang 31 reloading process conducted process improvement and optimization of cutting parameters of cutting tools and processing time, and improve the adjustment process, the high-end CNC tool to give full play to the role of the customer to obtain higher yields.
Start with the cooperation process ISCA minister Lv Yan 31, reinstall the process to say: "31 heavy use of iscar, is our most correct choice, not only brought us high productivity, high quality products, but also brought the spirit of innovation of world without end."
