Long-stroke high-frequency-response quick cutter servo device

Abstract

The invention discloses a long-stroke high-frequency-response quick cutter servo device, which comprises a driving component and a cutter saddle moving component. The driving component is mounted on a mounting component, the cutter saddle moving component is connected with the driving component and consists of a floatation guide track supported by a floatation support component, one end of the floatation guide track is connected with the driving component, and the other end of the floatation guide track is connected with a cutter saddle provided with a cutter. The long-stroke high-frequency-response quick cutter servo device has the advantages of high processing precision, long stroke, high speed of the cutter, high acceleration and the like.

Description

technical field [0001] The invention mainly relates to the field of ultra-precision processing mechanical equipment, in particular to a fast tool servo device. Background technique [0002] Ultra-precision machining is a processing method that has reached or has reached the highest dimensional accuracy in a certain period. At present, the precision of ultra-precision machining has ranged from micron to sub-micron or even nanometer level. It is widely used in optical systems, electronic information, automobiles, household appliances and weaponry, etc. field. Ultra-precision machining equipment must have extremely high motion accuracy. The straightness of the guide rail must reach the sub-micron level within the full stroke range (hundreds of millimeters), the rotation accuracy of the spindle should reach tens of nanometers, and the resolution of linear motion should be below the nanometer level. With the development of modern optical technology, non-rotational symmetric surf...
