What main shaft high speed changes is transitional

The graph is shown 1 times in be the machinery that each JIMTOF exhibited in the past, the metabolic circumstance of the top rotate speed of main shaft. To eleventh till the machine that top rotate speed exceeds 10000r/min has hardly. Arrive dozenth later, below the premise that also is the progress in machine tool technology, main shaft high speed is changed begin to show. After going to the 14th especially. Fast main shaft also can produce the freeboard that exceeds 10000r/min, the high speed of main shaft changed technical development to get be accelerationed in the round. The relevant technology domain that will realize main shaft high speed to change now is shown at the graph 2.

In these domains, as indispensible to scroll bearing technology, can the example of adduce has: Press beforehand adjust technology, axes cooling technology, inside raceway is lubricant technology, oily drop (oil gas) lubricant technology is waited a moment. But, the 19th JIMTOF with highest cry is changed to go up in high speed, exhibiting major machinery is in 10000r/min - 25000r/min, stay in 15000r/min likely. Additional, fat is lubricant had advantage still fails to make tall evaluation kill, in some respects, present high speed changes the side of a technology that the technology is the high speed machining that the graph shows 3 times only, that is to say, realizing main shaft high speed to rotate just is a requirement.
