Properties of Brass H62:<\/span><\/h2>\n

H62 brass represents ordinary brass with an average copper content of 62%, ordinary brass is based on the addition of other elements of copper alloy be called special brass and it is still represented by \u201cH\u201d, followed by the chemical symbol and average composition f other added elements. Such as H62 where the copper content is 60.5%~63.5%, and the remaining content is zinc. HA59-3-2 indicates that its copper content is 57%~60%, aluminum content is about 2.5%~3.5%, nickel content is 2%~3%, and the remaining content is zinc. There are three kinds of brass that are divided into ordinary brass, special brass, and cast brass. Cast brass begins with ZCu followed by the symbol of other elements and their average content.<\/span><\/p>\n

Ordinary brass has good mechanical properties, it has good plasticity in the cold state, and better plasticity in the hot state. Has good machinability, easy brazing, welding, and corrosion resistance, but it is easy to produce cracks. In addition, the price is cheap and widely used in a common brass variety.H62 brass is much harder at room temperature in \u03b2 phase than in a phase, so it can be used for parts that bear large loads.\u201ca+\u201d two-phase brass can be hot machining above 600\u2103.Microstructure of a+\u03b2 two-phase brass: a is a bright white solid solution and \u03b2 is a CuZn-based ordered solid solution.<\/span><\/p>\n

It can make all kinds of tensile and bending manufacturing stress parts, such as pins, rivets, washers, nuts, ducts, barometer springs, screen mesh, radiator parts, etc.<\/span><\/p>\n

Tipo de herramienta<\/strong>:\u00a035\u00b0round turning tool,2MM cut-off tool,\u22057.1 drill bit,\u22058 boring tools,\u22058 inside threading tools,\u22055.5 drill bit,1\/4-32 screw tap,\u22058 milling cutter,\u22051.5 drill bit,\u22051.5 milling cutter<\/span><\/p>\n

According to the drawing analysis the copper valve parts haven\u2019t special precision requirements in the shape and position tolerance. Therefore, we choose the direction of the 5\/8 thread of the parts as the priority for machining, because there is a requirement of R0.5 Angle in this direction. In order to fillet R0.5 Angle and the cylindrical inclined plane and end face processed surface connection relationship is more perfect.<\/span><\/p>\n

Use a 35\u00b0round turning tool machining parts shape, then use \u2205a 7.1 drill bit, \u2205and 8 boring tools to machine \u22057.1 and 5\/8 x18 thread bottom hole.<\/span><\/p>\n

\"\"\"\"<\/p>\n

Use \u22058 inside threading tools to machine 5\/x18 thread, then use \u22051.5 drill bit,\u22051.5 milling cutter to machine hole of \u22051.5\u00d73.5 size, then use \u22055.5 drill bit,1\/4-32 tap screw and \u22058 milling cutter to machining \u22059.5 and 1\/4-32 thread, then cut off the parts use 2mm cut off tool.<\/span><\/p>\n

\"\"\"\"<\/p>\n

It is necessary to custom clamp before processing at both ends, the male thread 5\/8\u00d718 length is 11mm. As the following picture shows:<\/span><\/p>\n

The reason is that the surface is the inclined plane of these parts and there is no clamping condition. So it only can be assembled with a 5\/8\u00d718 internal thread which has been machined with the 5\/8\u00d718 external thread of the fixture. Then processing of the remaining part<\/a>, not only ensure the repeated positioning error of the parts but also improved the processing efficiency.<\/span><\/p>\n

Use a 35\u00b0round turning tool to machine a total length of 59mm, then use \u22057.1 drill bit and \u22058 boring tools to machine 1\/2\u00d720 thread. Finally, make surface treatment of chrome plated.<\/span><\/p>\n
