由于高效自动机床上采用了快换设施以后,就能经济合理地用于较小批量的生产中,因而许多较小批量生产领域的生产状况正在得到改变。这种快换设施甚至在通常仅适用于连续工作的自动线中已得到应用。 勘尼和泰勒卡——麦温公司制造了一条包括自动线和组合机床在内的生产线。这条线用来加工13种不同型号的重型汽车后桥壳体;该自动线用于快速更换生产各类工件,采用了大量的快换装置。当负荷率为70％时,其产量为每小时12件。各种后桥壳体的长度是不同的,从5呎到5呎1C时,而它们的重量均在200磅以上。至于孔的分布、孔径以
Since efficient automatic machine tools are used in quicker conversion facilities, they can be used economically and economically for smaller batches and production is being changed in many smaller batches. This quick change facility has even been used in automatic lines which are usually only suitable for continuous operation. Gannet & Taylor-Maxwell manufactures a production line that includes automatic line and combined machine tools. This line is used to machine thirteen different types of heavy duty rear axle housings; this automatic line is used for quick changeover of all types of workpieces, using a large number of quick changers. When the load factor is 70%, the output is 12 pieces per hour. The lengths of the various rear axle housings vary from 5 feet to 5 feet 1C, all of which weigh over 200 pounds. As for the distribution of holes, aperture to
