Electric main shaft will be used extensively at numerical control machine tool

50 thousand increase to 3.

50 thousand (forecast at present can exceed 50 thousand) , the scale of main shaft of use report of numerical control machine tool also will by 6.

7% increase 40% the left and right sides. Predict 2005, numerical control machine tool goes to increase sharply 20000 with electric main shaft, occupy the 2/3 of quantity of total demand of electric main shaft about, replace the market position that grinds the main shaft that use phone, become the main force of market of electric main shaft. Meanwhile, the demand of the tall accurate bearing that place of main shaft of numerical control machine tool needs also will increase quickly. Use 4~5 on average to cover bearing computation by main shaft of machine tool of every numerical control, considering partial double main shaft or machine tool of much main shaft, by average every machine tool is deployed 1.

5 main shaft are calculated, to 2005 numerical control machine tool uses the demand of bearing of tall accurate main shaft to will increase 240 thousand, add maintenance to use bearing, quantity of total demand will achieve 480 thousand. Basis of association of industry of machine tool tool demand of machine tool of domestic numerical control, to each function component manufacturing dominant unit puts forward aggrandizement to expand a demand: The total output of unit of electric main shaft that electric main shaft asks to was used at numerical control machine tool 2005 achieves 3000 to cover, achieve 10000 to cover to 2010. According to estimation, by at present productivity grows rate, to 2005 our country can develop unit of 2000 main shaft that cover report only at most. If the country is sent politics appoint employ support of aggrandizement of national debt capital, to 2010 enlarge produces the likelihood to be covered to 6000, the others breach still needs to be solved through the entrance.
