1, CNC system
Domestic machining center CNC system market share is basically held by imported brands. High-end machine system is almost forbidden to the German Siemens 840D, mid-range is Japan Fanuc (Fanuc) and Japan Mitsubishi's world, the low-end by the Taiwan Bao Yuan, Taiwan's new generation, the domestic Kayenti, the domestic Huazhong, the domestic number of systems such as the division of a small share of the market.
Choice of method: five-axis vertical plus system is recommended to use Siemens 840D or Fanuc 31i, not the old gold mean, in the world of five-axis domestic and the world's advanced level of the gap is more than 10 years, such as Huazhong and the number of five-axis used to teach the number of can be capable of; high-speed, high-precision machining three-axis, four-axis vertical plus, Fanuc 18i and Mitsubishi M700 to fight a difficult distinction ; general application of three-axis vertical plus, Fanuc 0i and Mitsubishi M70 is a pair of happy enemies: Fanuc 0i MD-A suitable for mold processing, Fanuc 0i MD-B suitable for product processing, Fanuc 0i Mate-MD is an economical system, Mitsubishi M70-A for mold machine, Mitsubishi M70-B for product machine, generally believe that Fanuc's control is more Simple stability is higher, the same grade Mitsubishi more powerful; in the requirements of the occasion is not high as well as budgetary constraints, the domestic CNC system can also be a great show of force, in all fairness, in recent years, the rapid development of domestic machining centers system, is their progress to force the price of foreign brands of CNC systems to plummet; Taiwan's Bao Yuan and the new generation, the main application of the engraving and milling machine industry, in the stand plus a certain number of applications.
As for the functional differences between the various CNC systems, not in a few words can be clear, later open a topic to speak.
2, electrical system
Liga electrical system, the United States of America's GE, France's Schneider, Japan's Omron occupies the mainstream position, low-end models, there is no lack of domestic Chint, the shadow of the domestic Delisi. With the maturity of spindle servo technology and price reduction, inverter due to the inability to solve the problem of rigid tapping, has gradually withdrawn from the field of Liga.
Selection method: the match between the electrical components is very critical, the electrical performance of the degree of cooperation, adaptability, determines the stability of the electrical system. Not all components using the same brand can solve the compatibility problem, compatibility needs precision calculation, experience and technical accumulation.
3, lubrication system
Good lubrication is necessary to ensure the smooth movement of the machine. Where there is contact between the moving parts need to have lubrication to protect, no machine tool lubrication system, the life of the machine tool and precision will be greatly affected. Careful observation of the oil lubrication system of the machine tool is a must before purchasing Riga.
Selection method: screw bearing housing, nut housing, guideway, ball screw these parts must have oil circuit to reach, while considering whether the oil circuit layout is reasonable, maintenance and replacement is convenient. Oil circuit wiring confusion, oil pipe and other pipelines mixed, interference, the main moving parts lack of lubrication of the machine tool can not be purchased. Cooking to put oil, machine tool use the same need for oil.
4, bed (including guide rails)
With the success of Taiwan's machining centers optical machine mode, as spring up countless optical machine factory, mainly concentrated in Yunnan, Fujian, Shandong, Zhejiang and other places. Yunnan's Taizheng, Kun number, Fujian's Longsheng, Weino, Dehao, Shandong's Gordon, Haida, Ke Sheng, Zhejiang's Matt, Wu Dao, Jiangnan, etc., is more typical of the optical machine factory, to name a few, the industry is more recognized Taizheng's optical machine reliability rate is higher. Manufacturing their own bed machining center manufacturers have been a handful of Nantong Science and Technology, Changzhou Xinrui (formerly Jiangsu Doling), Suzhou New Wave, Zigong Changzheng, Qinghai a machine, Ningbo Haitian, Hsinchang Rifa, etc., is only a few of the surviving factories, Taiwan's Dongtai, Taichung, Liwei, Fuyu, Friends of the Jia, Aiguo Ma, and so on, but also their own manufacturing beds.
Selection method: mold machine with hard rail, product machine with line rail, this is the industry recognized selection method. High-end machine from the Swiss Mikron, Germany Demagi, the United States, Harting, Japan, Japan, Mazak and other brands in the selection; mid-range machine can be considered South Korea's Hyundai, Taiwan machine tools, Hsinchang Rifa, Nantong Science and Technology, Changzhou Xinrui and other domestic first-tier brands; low-end machine is the world of the light machine gangs, the domestic famous Shen machine, cloud machine, Baoji, all in the ranks of the light machine gangs, which is reasonably configured, affordable, and service! On which one to choose, the cheapest machine tools can not have the best price-performance ratio, the largest machine tool sales is not necessarily the best machine tool, which you and I should understand.
