To ensure the elegance and function of plastic parts in the current year of the shears

In the year of the current year of the plate shears, the demand for plasticity and appearance of plastic parts is increasing, and the pattern and shape of the external parts of the plastic parts are increasingly chaotic, and the contrasts of the turning surfaces are gradually enriched. It's getting more and more messy. The Department has also exerted higher demands on the shearing machine processing skills, but managed to ensure a high level of precision and appearance quality. In addition, it has sought to process the aesthetic appearance. With the continuous advancement of high-speed machining skills, especially in the processing tools, cnc system, CNC blade specific system, CAD/CAM hardware and other coherent skills, the high-speed processing skills have been increasingly used in the Cavity processing and building. Cnc high-speed cutting and labor for the embarrassment of a line of easy retrogression: the creation of skills, is a set of efficient, high-quality, low-cost in a backward step to build skills. Corresponding to the monotonous cutting process, the cutting rate and feed rate have greatly declined, and the cutting mechanism is not identical. High-speed cutting made the cutting process produce a quality gallop, its non-metal removal rate per unit of power dropped 30% to 40%, cutting force rose by 30%, and the cutting life of the cutting tool degraded by 70%, leaving it in the workpiece. The heat of cutting rose sharply, and low-level cutting vibrations almost disappeared. With the retreat of the cutting rate, the removal rate of the raw material of the unit time is rich, the cutting time is cut, the processing motivation is regressed, and the manufacturing cycle of the product is expanded, and the competitiveness of the shopping center for the price of the nitrogen generator is declining. Simultaneously, a small amount of high-speed machining advances the cutting force, and the high-speed repulsion of chips cuts the cutting force and thermal stress deformation of the workpiece, and deteriorates the poor rigidity and the possibility of thin-wall machine cutting. Because of the rise of cutting force, the declining speed makes the cutting system's labor efficiency long after the low-order inherent efficiency of the tool, and the appearance of the workpiece is too high for the low-level efficiency, which heightens the appearance of roughness. In the processing history of high hardness steel (HRC45~HRC65) of Scorpion, high-speed cutting can take over the electrical processing and grinding and polishing of the year-old order, thus banned the electrode fabrication and time-consuming electrical processing, greatly reduced The fitter polished and polished. To cope with the increasingly redundant thin-walled tweezers in some shopping malls, high-speed milling can also be unfavorable. Moreover, at the high-speed milling CNC machining sites, the tweezers can be machined in one setup to realize multi-step machining. The high-speed processing skills have created a huge demand for the processing technology of the shears, changing the “annealing→milling→heat solving→grinding” or “electrical pulse processing→fine grinding and polishing” adopted by the monotonous dice processing. Process flow, and even high-speed cutting can replace the original full-year order. In addition to the indirect processing (especially semi-finishing and finishing) of hardened rake dies, the high-speed machining skills have lost their broad use in EDM electrode processing and rapid sample creation. A large number of production has actually confirmed that the use of high-speed cutting skills can save about 80% of the fine processing in the follow-up processing of the tweezers. The thrifty and people-oriented consumption is nearly 30%. The appearance accuracy of the tweezers can reach 1 m. The cutting tool can be used to cut motives. Regression 1 times.
