At present, most domestic crankshaft production lines are composed of ordinary machine tools and special machine tools, and the production efficiency and automation degree are relatively low. Roughing equipment mostly uses multi-tool lathes to turn crankshaft spindle and crank neck, the quality stability of the process is poor, easy to produce large internal stress, difficult to achieve a reasonable processing allowance. General finishing by MQ8260 crankshaft grinding machine coarse grinding - semi-fine grinding - fine grinding - polishing, usually by manual operation, processing quality is not stable.
With the arrival of the globalization of trade, the manufacturers have realized the seriousness of the situation, have carried out technological transformation, and strive to enhance the competitiveness of enterprises, and the progress is very fast. These equipment and technology are basically imported.
