Overview of precision machinery parts processing technology
Precision machinery parts processing method includes repair size method, additional parts and parts of local law replace three kinds of law. Repair size method is to repair parts machined to size, such as cylinders, crankshaft and other repairs have size. If a certain repair parts processing size, the side associated with it was another part must be machined to the appropriate repair size, so that a certain gap between the two standard fittings. Additional parts method is to wear Face machining parts to be able to install additional liner size. Precision machinery parts processing generally used for larger surface wear parts, such as valve seats, gearbox bearing bore and the like. Local law is to replace the parts removed from the parts wear section, remove sized portion of a new product, and make it part and I remain part welded together, such as axle, replace worn spherical shift lever
However, the crankshaft roughing widely used CNC lathes, within CNC milling, CNC broaching machine and other advanced equipment for the main journal, connecting rod journal CNC Turning, Milling, cars - broaching to effectively reduce crankshaft machining Shenzhen Machinery deformation processing plants. The crankshaft finishing widely used CNC crankshaft grinder control its journal were fine grinding. Such grinding machine will be equipped with automatic grinding wheel balancing device, the center frame automatic tracking, automatic measurement, automatic compensation device, automatic grinding wheel dressing, and other functional requirements of the constant linear velocity, precision machinery parts processing to ensure stable grinding quality. Situation precision machinery parts processing high-precision equipment dependence on imports, is not expected to change in the short term.
