For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The
How Do Cnc Swiss Machines Work Save 0 What Is Swiss Machine –The full name of the walking CNC lathe, it can also be called the spindle box mobile CNC automatic lathe, the economical turning and milling compound machine tool or the slitting lathe. It belongs to precision machining equipment, which can complete compound machining such as turning, milling, drilling, boring, tapping, and engraving at one time. It is mainly used for batch machining of precision hardware and special-shaped shafts. This machine tool first originated in Germany and Switzerland. In the early stage, it was mainly used for precision machining of military equipment. With the continuous development and expansion of industrialization, due to the urgent needs of the market, it was gradually applied to the machining of civilian products; the development of similar machine tools in Japan and South Korea Earlier than China, it was mainly used in the military industry in the early days. After the war, it was gradually
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 compression spring, including the outer diam
Bolts and screws are a common connection fasteners, which mainly play a role in connection and fixation in various fields and equipment.A lot of people sometimes screw and bolt to the wrong, easy to confuse.China Hardware is going to share the differences between fastener bolts and screws today. I hope it will be helpful for you to use bolts and screws again in the future.
The difference between bolts and screws of fasteners:
1. Different definitions of bolts and screws for fasteners:
Bolt: A bolt is a cylindrical threaded fastener used in conjunction with a nut during service.It is mainly used for fastening and connecting two parts with through holes. This kind of connection form is called bolt connection.
The screw, also known as the screw, screw is the use of the object's beveled circular rotation and friction force of physics and mathematical principles, the gradual cycle of fastening tools.The setting screw is used to fix the relative position of the machine parts.The setting screw is screwed into the screw hole of the part to be fixed, and the end of the screw is pressed on the surface of another part, that is, the former part is fixed on the latter part.
2. Different shape and structure of fastener bolts and screws:
Bolt: A type of fastener consisting of a head and a screw (cylinder with external thread), usually having a hexagonal head and generally larger head.
Screw: a kind of fastener composed of head and screw parts. The head is mostly a word groove, a cross groove, and a lot of hexagons inside and outside, generally smaller.
3, fastener bolt and screw application is different:
Bolts: usually used in pairs with nuts, for through holes, easily replaced after damage.
Screw: usually do not need nuts, directly with two objects (general connector first to drill, tapping) used for blind holes, connecting parts are rarely disassembled.
4. Different tools are used for fastener bolts and screws:
Bolts generally use wrench tools.
Screw generally use subclass tools.
5. Different fastening between bolts and screws of fasteners:
Bolts are usually used in conjunction with nuts or screwed into the holes of processed bolts.
In addition to the two fastening methods of bolts, there are also self-tapping screws, which are directly screwed to the workpiece with soft material without processing the bolt hole. For example, the wood screw we say is this kind of screw.
6, fastener bolts and screws used in different occasions:
The use of bolts and screws is different, the precision of the bolt is not high, unless there is a requirement to cooperate with the general bolt disassembly is convenient, low processing accuracy, is not limited by the connection material, widely used, the bolt required to cooperate with, can withstand the transverse load;Screw is compact in structure, but cannot be removed frequently, and cannot withstand large forces.
