Engine Spare Parts Breakthrough Progress

The engine is the vehicle's "heart", the automobile development and the engine progress has the direct relations, the engine mainly by 5 big key components, Engine Spare Parts including the cylinder body, the cylinder head, the crankshaft, the camshaft, the connecting rod and so on, therefore these core parts processing becomes the automobile engine manufacture key.

The cylinder body and the cylinder head are the core parts of the engine, and they are the items that almost all the engine manufacturers must choose. At present, Engine Spare Parts the main trend of machining development of cylinder body, cylinder head and other box parts is that the flexible production line, which is composed of CNC machine tool and machining center, replaces the rigid production line based on the combination machine gradually. Engine Spare Parts In order to meet the needs of mass production, a flexible manufacturing unit (FMC) and multiple machining centers (FMS) are developed to meet the needs of different varieties and batches of manufacturing. With the popularization of CNC control system and the development of new tool materials, the high-speed modular machining center has made breakthrough progress in the 90 's, and the flexible processing system composed of high-speed machining center has been widely used in actual production.

Cylinder body is the total bearing of all the parts, Engine Spare Parts and the common structure of cylinder body is an approximate hexahedral box-type structure, thin-walled, machining surface, hole system is more, is a typical box parts, the main processing has cylinder hole, main bearing hole, camshaft hole, etc., has lubricating oil road, cooling water road, installation screw hole and other holes, Engine Spare Parts there are many kinds of coupling, sealing with convex table and facet , their machining accuracy directly affects the assembly precision and working performance of the engine, meanwhile, in order to improve the body stiffness and strength, Engine Spare Parts there are many reinforcement.

Cylinder hole Processing: the use of coarse boring, half fine boring and precision boring, honing mode processing. The main bearing hole processing: The general use of roughing semicircle hole, and then with the camshaft hole combination finishing. Camshaft Hole Processing: general use of coarse boring, and then with the main bearing hole combination finishing. TAPPET Hole Processing: The general use of drilling, Engine Spare Parts expansion (boring) and reaming machining methods. The main oil channel hole processing: the traditional processing method uses the twist drill to carry on the grading feed way processing, its processing quality is poor, Engine Spare Parts the production efficiency is low, the current craft often uses the gun drill to carry on the processing.
