Abstract

The invention relates to an ultra-precise lathe which comprises a supporting device (1) and a lathe body (2) arranged on the supporting device (1). A pair of lathe body guide rails (21) is arranged onthe lathe body (2), and a tailstock support (3) is fixed to the left end of the lathe body (2) and provided with a headstock (5); a first tailstock sliding block (4) arranged on the guide rails (21)is movably fixed to the right end of the lathe body (2), and a second tailstock sliding block (7) is slidably arranged on the first tailstock sliding block (4); a tailstock (8) is arranged at the topof the second tailstock sliding block (7), and a roller mold (6) is arranged between the tailstock (8) and the headstock (5); and a cross-shaped sliding table (11) is further slidably connected abovethe guide rails (21) and between the tailstock support (3) and the first tailstock sliding block (4), and a static pressure rotary table (10) is arranged on the cross-shaped sliding table (11) and provided with a knife rest (9). The ultra-precise lathe is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to an ultra-precision lathe. Background technique [0002] Ultra-precision machining technology is an advanced manufacturing technology developed in the 1960s. The machining accuracy of parts depends on the accuracy of ultra-precision machine tools. Ultra-precision machining technology comprehensively utilizes cutting-edge scientific and technological achievements in the fields of measurement, servo control, optics, environmental control, sensing, and hydraulic pressure. [0003] One of the more important difficulties in the ultra-precision machining of large-scale microstructure roller molds is that due to the long processing time and large workpiece size, the roller mold is extremely sensitive to thermal errors of internal heat sources and external heat sources. Usually, the processing time of the micro-structured roller mold takes tens of hours or even hundreds of hours. During this process, the heating of the motor spindle, t...
