CNC pin-point gate machining process and device and product

Abstract

The invention relates to a CNC pin-point gate machining process. The process comprises the following steps of lathing and tapping a mold to obtain a rough gate hole close to a target size; lathing and finely trimming the rough gate hole to the target size to obtain a finely trimmed gate hole; lathing the bottom of the finely trimmed gate hole to form a bottom concave surface; and lathing the formed bottom concave surface, and forming a taper hole. By applying the technology, only CNC machining needs to be carried out, time consumption is 45 H, the cost is about 600 RMB, multiple procedures are omitted, one-stop production is achieved, the production period is short, the cost is low, online detection is easy to achieve, the quality control difficulty is low, the abnormal risk is low, the glossiness is high, polishing is not needed, and the machining efficiency of a nucleic acid disc mold is greatly improved.

Description

Technical field [0001] The present invention relates to the field of nucleic acid disk mold processing, and more particularly to a CNC processing fine water proof process, apparatus and article. Background technique [0002] At present, for a nucleic acid disk mold with a 96-cavity of 0.4 mm fine water port, it is often used because of a conventional CNC processing method, which is usually used, and the specific steps are required: electrode design - electrode processing - sparks Four steps of machining - polishing processing, where the electrode design is 1.5H, the cost is about 500RMB; the electrode processing is 30 h, the cost is about 3600RMB; the spark machine processing is 36 hours, the cost is about 280RMB; polishing processing and processing time 20h, Cost 2400RMB; total production is 87.5 hours, total production costs 9380RMB; more process, long manufacturing cycle, high cost cost, high quality control, high processing risk. Inventive content [0003] The technical prob...

Problems solved by technology

[0002] At present, when processing the nucleic acid disk mold with 96 cavities and 0.4mm fine nozzles, because the conventional CNC processing method cannot be used for processing, the EDM method is usually used. The specific steps require: electrode design-electrode processing-spark Machining-polishing four steps, of which: electrode design takes 1.5H and costs about 500RMB; electrode processing takes 30H and costs about 3600RMB; spark machining takes 36H and costs about 2880RMB; polishing takes 20H, The cost is about 2400RMB; the total production time is 87.5H, and the total production cost is 9380RMB; there are many processes, long manufacturing cycle, high cost, difficult quality control, and high processing risk
