To achieve these goals, the utility model is achieved through the following technical solutions: a kind of miniature accurate two-wire processing line cutting off machine, mainly by wire drive device (1), workbench (2), planker (3) and lathe bed (4) are formed, wherein: the silk cartridge (11) of wire drive device (1) is fixed on the stand (15), stand (15) is connected with lathe bed (4), silk cartridge (11) is connected with leading screw (12) with drive (117) by gear train (113), leading screw (12) is spirally connected with connector (121), connector (121) is used bolting with guide frame (13), silk cartridge (11) intersects running with (2) 90 ° of workbench, molybdenum filament (132) is by tight silk wheel (141) and four closed solderless wrapped connections of guide wheel, molybdenum filament (132) is by shelves silk positioners (16) and guide wheel (131) location, wire drive device (1) is affixed with workbench (2), and workbench (2) is arranged on lathe bed (4) with planker (3) and goes up the overall of composition lathe.

Owing to adopted technique scheme, the utlity model has following advantage and effect:

1, the utility model one cutting silk can be processed two workpiece simultaneously, has improved operating efficiency;

2, machined surface of the present utility model is preceding, makes silk simple, is easy to change silk, need not wear silk, and the tight silk device of the tension force that is adopted is simple in structure, and reliable operation is different from the structure of the easy fracture of wire of sliding weight of steelyard formula that fast wire adopts;

3, the shelves silk positioning device structure novelty of the utility model employing, reliable operation;

4, the utility model is simple and compact for structure, and volume is little, and cost is low, can carry out Precision Machining, and its processing stepping can reach (1～0.1) μ.The utility model working service is repaired simple and easy.
