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...

Problems solved by technology

[0003] Existing ultra-precision machining methods based on advanced numerical control technology, especially single-point diamond cutting technology, have been widely used in non-rotational symmetric surface processing, but currently for non-rotational symmetric optical surfaces with a height difference of several millimeters, the existing The stroke of the fast tool servo device is not enough, the frequency response of the slow tool servo is low, the processing cycle is long, the accuracy is affected by the environment, and the milling efficiency of the flying knife is low and it is not suitable for the processing of certain surface shapes. Therefore, it is necessary to study a large stroke , High-response, high-precision tool servo system to solve the processing of this type of non-rotational symmetrical surface
