Coarctation hole series multi-operation part process technique and special equipment thereof

Holes dense multi-step process and equipment parts, the process comprising feeding, cutting, and between upper loading and unloading means comprising a plurality of multi-station processing sequentially, which equipment comprises a machine base, at least having two stations displacement slide, displacement slide, fixed displacement sliding table jig, the feed slide, the power box, headstock, cutter aids, and the machine control system having a drive headstock the system and at least two spindles, each spindle having a shaft and an output corresponding to the displacement of the working phase of the slide, the spindle is provided with corresponding clamp locating means on the clip, is provided between the positioning of the workpiece in the clamping device can clamp bit string tightening device between the feed mechanism. Sequentially arranged processing multi-station processing unit, and the synchronization, the workpiece is machined by the order of individual processing units, and multiple simultaneous machining of a workpiece, which makes the processing time to get a high overlap, the process efficient use of resources, improve production efficiency.
