Which one is harder, brass or copper?       Copper has good electrical conductivity, thermal conductivity and ductility. It is widely used in cables and electrical and electronic components. Because of its low melting point, it is easy to remelt and re-smelt. It is also a relatively environmentally friendly material. Among them, brass and red copper are widely used. Many companies do not know which brass or red copper has high hardness, which leads to errors in the production. The following technicians will introduce to you which hardness of brass parts or red copper is high?   brass     What is copper?     Purple copper is named for its purple-red color. It is a relatively pure copper. It is not necessarily pure copper. Generally, it can be approximated as pure copper. It has good electrical conductivity and plasticity, but its strength and hardness are worse.     What is brass?    Brass is an alloy composed of coppe...

The configuration method of the spindle bearing of the CNC machining machine tool   Generally, the spindle components of medium and small CNC machining machine tools mostly use rolling bearings (bearing) as the spindle support. At present, there are mainly the following three deployment methods:   1. The front support adopts double row short cylindrical rollers   Bearing and 60. In the numerical control processing, the control system issues instructions to make the tool perform various motions that meet the requirements, and the shape and size of the workpiece are expressed in the form of numbers and letters, and the processing required by the manufacturing technology . It generally refers to the process of processing parts on CNC machine tools. In order to improve the degree of production automation, shorten the programming time and reduce the cost of CNC machining, a series of advanced CNC machining technologies have been developed and used in the aerospace ...

Selection of Surface Machining Methods for Inner Hole of CNC Lathe Machined Parts   There are many methods for surface processing of inner holes of CNC lathes. Commonly used are drilling, reaming, reaming, boring, turning, grinding, drawing, grinding, honing, and rolling holes.   Applicable method for inner hole machining of CNC lathe machined parts:   1. Drilling: Drilling holes in the solid part of the workpiece with a drill is called drilling. CNC cutting is a process method for parts processing on CNC machine tools. The process regulations of CNC machine tool processing and traditional machine tool processing are generally the same, but significant changes have also taken place. A machining method that uses digital information to control the displacement of parts and tools. It is an effective way to solve the problems of variable parts, small batches, complex shapes, and high precision, and to achieve high-efficiency and automated processing. The drilli...

What is 3d printing rapid prototyping technology     3D printing technology   A technique for layer-by-layer printing. By connecting a computer with a 3D printer, the drawn drawings can be printed out as a means of model. Today, this technology is used in many fields, and people use it to make clothing, architectural models, cars, chocolate desserts, and more.   The advantages of 3d printing technology     3D printing is very different from traditional production through molds. The biggest advantage of 3D printing is that it can be produced without machining or any molds.   Generate parts of any shape directly from computer graphics data, thereby greatly shortening product development cycles, increasing productivity and reducing production costs. At the same time, 3D printing can also print some shapes that cannot be produced by traditional production technologies. At the same time, 3D printing technology can also simplify the entire...

Spring Design Attention And Roll Forming Method The coiling characteristics and methods of springs are divided into cold coiling method and hot coiling method. Cold winding method: When the diameter of the spring wire is less than 8mm, the cold winding method is adopted. High-quality carbon spring steel wire is usually first cold drawn and then heat treated. After winding, it is generally not quenched, but only tempered at low temperature to eliminate the internal stress during winding. Hot-rolling method: Springs with larger diameter (>8mm) spring wire should use hot-rolling method. Hot rolled springs must be quenched and tempered at medium temperature. The Design Process Of Various Springs ·          Installation space: When designing a  compression spring , it is necessary to have a clear understanding of the space required for the installation of the spring, in order to effectively grasp the basic manufacturing conditions of the ...

What are the metal product processing technologies of precision sheet metal processing manufacturers   Precision sheet metal processing manufacturers CNC bending machines, etc. to produce sheet metal products. Can go directly from drawing to product paperless production. It is suitable for flexible production of small batches and multiple varieties. The sheet metal bracket is very powerful, and many sheet metal part features need more tedious operation steps to be realized under the modeling module. Three aspects of punch automation in sheet metal automation processing are briefly discussed.   Casting: Refers to the metalcasting being heated and melted and then poured into the model. It is suitable for processing parts with complex appearance.   Casting classification of sheet metal processing plants   Sand casting : The cost is low, the batch size is small, and complex shapes can be processed, but it may require a lot of post-processing steps. I...
