Product description, features and application domain information
The Cylinder head of gasoline engine is usually made of aluminum.The cylinder head is a component of the combustion chamber, and the shape of the combustion chamber has a great influence on the work of the engine.The combustion chamber of a gasoline engine is mainly on the cylinder head, while the combustion chamber of a diesel engine is mainly on the pit at the top of the piston.At the same time, if the valve center deviates too much from the valve seat ring center during engine operation, the engine power will decrease and fuel consumption will increase, but also accelerate the wear of valve and pipe hole.Therefore, the machining accuracy of valve seat ring and ducthole, especially the working cone of valve seat ring, sets a strict tolerance limit on the pulsation of ducthole.The machining accuracy of valve seat ring and pipe hole of engine cylinder head is generally required to be: the coaxiality tolerance of gasoline engine is required to be (0.015 ~ 0.025) mm;The diesel engine is only (0.01 ~ 0.015) mm, the conical runout is (0.03 ~ 0.05) mm, the hole accuracy level requirements are generally H7.

Computer digital control machine tool is a kind of automatic machine tool with program control system.The control system can logically process and decode programs with control codes or other symbolic instructions so that the machine can move and process parts.English abbreviation CNC, is the abbreviation of the English Numerical Control, also known as CNC machine tools, CNC lathes, Hong Kong and guangdong pearl river delta area known as computer gongs.CNC lathes are mainly used for large - scale machining of parts, including the machining of round, boring, turning plane and so on.Can write the program, suitable for mass production, the automation of the production process is higher.
We have professional testing personnel to use a variety of equipment to control the quality of products
HB is generally used when materials are soft, such as nonferrous metals, steel before heat treatment or after annealing.Brinell hardness (HB) is a test load of a certain size, a certain diameter of hardened steel ball or hard alloy ball is pressed into the surface of the metal under test, and kept for a specified time, then unloading, measuring the diameter of indentation on the surface under test.Brinell hardness is the quotient of the load divided by the surface area of the indentation.The hardened steel balls of a certain size are pressed into the surface of the material under a certain load and kept for a period of time. After unloading, the ratio of the load to the indentation area is brinell hardness value (HB).
We have a strong professional technical team and r & d strength, as well as a variety of certificates.
