Crank the engine of development of processing technology trends
After entering the 21st century, the engine crankshaft manufacture process, tools in all aspects. Leadership for nearly half a century of many knives cutting process and manual process, due to the low and the poor flexible machining precision, is gradually from the stage of history. High-speed, high pound processing technology and equipment quickly into the automobile and automobile parts manufacturing, high pound processing technology in the crankshaft production process in a degree of application, and will be the inevitable developing trend.
The crankshaft processing technology and equipment status
At present, the domestic older crankshaft production by ordinary machine and the most special machine, production efficiency and automation is relatively low. Balancing device generally adopted the crankshaft lathe cutting knife shaft neck and neck connecting shaft, working procedure quality stability, easy to produce large processing stress, difficult to achieve reasonable . Widely used as ordinary precision MQ8260 crankshaft grinding machine for the coarse grinding and fine grinding, polishing, grinding, usually by artificial operation, the processing quality instability, dimension tolerance.
One of the main characteristics of old line is mon, processing equipment, ductile iron crankshaft assembly
