Industry of Chinese machine tool came true to exceed high speed to develop continuously, arrive all the time 2011 first half of the year, demand still very exuberant, enterprise of great majority machine tool is in produce and sale in the excited condition of two flourishing. But from last year second half of the year begins, demand is added sign is clear hasten delay, sheet of new revise and enlarge is acuteness glide, economic benefits state tends gradually austere, profit margin drops continuously. Although the high speed first half of the year increases mat base, total production value of annual China machine tool industry was added last year fast still arrive by the nearly 39% fall after a rise of the beginning of the year 32.5% of year end; Implementation profit is added fast fall by the 57.5% drama of the beginning of the year 29.8% to year end. Visible, the phasic change of industry of Chinese machine tool is acuteness last year. Homebred machining center entered fast hair exhibition period, current machining center with its efficient with high accuracy, get rapidder and rapidder development, already made the product that numerical control machine tool develops the fastest, place to occupy a proportion is the largest kind in of all kinds product, also be a kind of equipment with manufacturing industry the widest application, already made consumptive main trend. Developed country of a few main economy is the first job that regards machine tool of development numerical control as development machining center more, its development matters to national economy construction and national defence safety directly. 2011, the entrance of industry of Chinese machine tool is 20.7 billion dollar, and exit is 7.3 billion dollar, adverse balance of trade of imports and exports is as high as 13.4 billion dollar. Visible, the demand of product of tool of Chinese machine tool is objective existence, it is enterprise of domestic machine tool cannot be satisfied adequately only just; If can accomplish imports and exports to be balanced basically, chinese machine tool industry can increase the sale of 13.4 billion dollar completely last year again.
The Krallmann group that Germany hopes to ascend dark of a person of extraordinary powers is made in die-casting tool and plastic technology domain is world-famous. Recently, the plant investment that independent tool of Xidenghaosen makes an enterprise be located in Sauer from Demaji introduced HSC20linear of machining center of 5 axes high speed. Of this equipment (standard) main shaft rotate speed can be achieved minutely 42000 turn. Meanwhile, krallmann still ordered PH10~100 of tray storage system, so that be in nightly and realize unmanned operation on the weekend. Outside can achieving unconventional precision with modular chamfer besides the rough sketch that treatment gives; The cupreous electrode appearance that production gives can achieve lens side effect almost. Divide this beyond, this equipment is returned can day and night keeps running continuously, because this can rise greatly,produce can. In view of with Demaji long-term and good, also be very successful collaboration at the same time, krallmann hesitates none almost the ground with respect to make choice of Demaji regards equipment as the supplier. Nevertheless, dust Er · Dr. Shi Baisi expresses company general manager and summer of rice of financial chief inspector: “Before investment introduces device of a new machine, people also can look the product that fastens the home and quoted price of course. Nevertheless, objective for, go soon, do not have any products and quote to be able to place on a par with the HSC20linear of automation. And the HSC20linear of automation also is one branch alone beautiful ” . The group is senior the Lainaer Kelaerman of leader and CTO, to HSC20linear whole of this one automation ties the configuration with compact interconnected system and simple operation, work especially open degree of the space, offerred affirmation.
The Nanjing that held recently agrees to believe technical appraisement of new product of accurate machine production company to be able to go up, experts express, function of machining center of vertical of high speed of milling machine of numerical control of 5 axes linkage, MMC740 stabilizes the VS655 that agrees to believe a company reliably, agree to pass appraisal. Appraisal is met on, agree to believe Li Jin of company general manager to introduce, come nearly 3 years, company and department of instrument of Tsinghua university nicety cooperate, the company threw millions yuan funds of new product research and development, the place of the main innovation of milling machine of numerical control of 5 axes linkage depends on VS655 use the left and right sides to swing the crucial technology of assembly of box of type main shaft, main shaft swings angle can from – 45 ° arrive 90 ° of ＋ , cooperate workbench circumgyrate, achieve 5 axes linkage, cutting space is large, tigidity is good, adjust convenient. Fit the part of complex curved surface such as impeller, lamina very much. Li Jin says, machining center of vertical of MMC740 high speed, main part is homebred change rate achieve 98 ％ , especially production success of main shaft of machine tool high speed and design of fast shuttle table reduced machine tool cost greatly, saved cost of very big brushstroke for the user, make machine tool more economy, practical, can older rate land creates value for the user, batch production produces per year a quantity to be covered in 200, predict this product sale is controlled in 40 million yuan. On the meeting, trade of Jiangsu province classics appoint, Nanjing city classics appoint, factory of machine tool of association of quality of city of university of industry of engineering courtyard of concerned chief of bureau of Nanjing city science and technology and Nanjing aerospace university, Nanjing, Nanjing, southeast university, Nanjing, Nanjing and national machine mass are supervised examine the appraisal of the composition such as the center, pass achievement appraisal, machining center of vertical of MMC740 high speed passes appraisal of new product put into production.
Heavy industry of 3 water chestnut rolled out large dragon door 5 machining center ” Plano-Machining MVR ” the ritzy type of series — inside column door wide be 4.25m ” Plano-Machining MVR 45 ” . Can machine Japanese Road Traffic Law to set upper limit (wide 3.5m) large metal component. Basically face the component such as liquid crystal, solar battery and the treatment that make coal tub component wait. Main shaft rotate speed is 6000rpm, fast feed speed is 18m/min. To achieve the lasting accuracy that runs for long and efficiency, through increasing column door and beam, raised the tigidity of whole machine tool. Additional, the slip orbit bizygomatic breadth that enlarging workbench while, orbit root number increased 4 from 2, the stability after ensuring workbench is increased thereby. The length of workbench is standard 6m. At this moment, but 35t of the biggest load. Workbench length can be 8m or 10m through choosing set, can part 30t of the biggest load and 25t. Match stock machine program to make software. This software has a program to assist a function, need to input a few information only can set a variety of treatment mode. In addition, undertake to can operating an area main maintenance works, in the operation the area configured a variety of device centrally, and to facilitate processing cuts bits, conveyer belt unit was provided in airframe interior, rose to be reached easily with the gender safeguard a gender.
Hill Qi campstool is overcome (Yamazaki MaZaK) development went drive source to introduce linear motor and direct drive (DD) 5 axle control of motor vertical machining center (MC) ” HYPER VARIAXIS 630 ” , exhibit on JIMTOF 2010. In synchronism on the workpiece cutting of 5 axle control, raised fast feed rate, shortened total handling time. In X (airframe is transverse) / Y (airframe takes deep way) / Z (airframe is perpendicular direction) linear motor all is used on the axis, rate of will fast feed rose 80m/ minute. And lever of silk of assorted use ball is mixed before normally motor fast feed speed is 40m/ minute, rate rose 2 times. Except raised fast feed rate through using DD motor besides, because tigidity is tall,return and without recoil, so treatment precision also can rise. Treatment object workpiece is mixed for the plane generate electricity the spare parts such as the use impeller such as equipment and car component. Can machine a diameter 730 × height (length) 500mm, the workpiece under weight 500kg. The price is 45.2 million yen (do not contain tax) . Already sold the European business that processes car component allegedly.
