1、 Anti rust coating process of construction machinery Anti rust coating process of construction machinery can generally be divided into pre coating, surface treatment process and anti rust, primer and primer coating process. 1: Surface treatment of steel shot and steel sand Surface treatment is one of the important processes of antirust coating. The quality of anti rust coating of construction machinery depends to a large extent on the way of surface treatment. The coating life is restricted by three factors: the surface treatment accounts for 60%, the coating construction accounts for 25%, and the coating quality accounts for 15%,…

FDM (fused deposition molding) technology is one of the most common 3D printing technologies, but it can be used not only for desktop level equipment, but also for industrial level equipment. As the inventor of this technology, Stratasys has shared some technical dry goods for the application of FDM 3D printing technology in industry. Now let's learn how to use industrial grade FDM 3D printing technology to print parts with variable density. Moreover, if the operation mode is proper, FDM technology can also greatly save time and cost. How to operate it best? See below: Step 1: Introduction The unique…

CNC lathe is an automatic machine tool with high precision and efficiency, which can process complex workpieces such as linear cylinder, oblique cylinder and arc. In order to ensure the working accuracy of the lathe and extend its service life, it is necessary to carry out reasonable maintenance. The common methods for maintenance and repair of CNC machine tools are: oil pouring lubrication, oil splashing lubrication, oil rope guide lubrication, marble oil cup lubrication, grease cup lubrication, oil pump oil delivery lubrication. The parts in the spindle box are lubricated by oil pump circularly or splash lubrication. The lubricating oil…

Injection molding machine is one of the plastic machines commonly used in plastic processing. The structure of plastic machinery injection molding machine is usually composed of injection system, mold closing system, hydraulic transmission system, electrical control system, lubrication system, heating and cooling system, safety monitoring system, etc. Injection system Function of injection system The injection system is one of the most important components of the injection molding machine, which generally has three main forms: plunger type, screw type and screw pre plastic plunger injection type. At present, screw type is most widely used. Its function is that in a cycle…

The numerical control electric discharge machining is to use the moving fine metal wire as the tool electrode, pass the pulse current between the metal wire and the workpiece, and use the electric corrosion of the pulse discharge to cut the workpiece. This kind of processing has the characteristics of high precision of parts, suitable for the processing of plane complex shape parts, flexible application, short processing cycle and material saving. Next, we will specifically introduce the characteristics of CNC WEDM. At present, in the research and development of new products, a large number of CNC wire cutting technology are…

How to repair the refrigerator when it breaks down? A refrigerator is a mechanical device that uses a compressor to change the pressure of refrigerant gas to achieve low-temperature refrigeration. It is useful in many equipment, such as central air conditioning. Generally, the refrigerator uses the tubular heat exchanger to complete the material heat exchange. When the carbon steel tubesheet is used as the cooler, the welds between the tubesheet and the tubular often have corrosion leakage. The leakage into the cooling water system will cause material waste and environmental pollution, and even affect the safety production of the enterprise…

NC machining technology is derived from conventional machining technology, which is an organic combination of conventional machining technology, computer numerical control technology, computer aided design and auxiliary manufacturing technology. With the continuous development of technology, more and more parts need to be precision machined in modern manufacturing industry, and the requirements for machining accuracy and surface complexity of workpieces are becoming higher and higher. Therefore, NC machining has been widely concerned, but in terms of cost saving, NC machining is still higher than traditional machining. Next, we will specifically introduce the difference between CNC machining and traditional machining technology. 1.…

In machining, the cutting tool is the basic process equipment for cutting. It is in direct contact with the parts to be processed. Different cutting tools can process different part structures and parts surfaces, which plays a vital role in machining. It can be called "industrial teeth". As a consumable, the tool itself has a certain life. Different materials and different specifications have different life; For mass production, tool consumption also occupies an important part in the processing cost. Therefore, improving tool life, controlling tool consumption, reducing processing cost and improving production efficiency are the common problems faced by manufacturing…
