1. Clean the grinder with a brush after daily operation. It is strictly forbidden to blow the worktable or guide rail directly with an air gun to prevent iron chips from entering the guide rail and affecting the precision of the grinder. 2. It is strictly prohibited to use a fan to blow against the workbench during operation, so as to prevent dust and iron filings from rolling back into the guide rail, which will affect the accuracy and feel of the guide rail. 3. The guide rail oil of the grinder should be replaced and added in time. Generally,…

With the gradual rise of people's demand, 3D printing enterprises are making their products bigger and bigger, just like the development of mobile phone screens. 3D printing is not a strange word, especially in manufacturing and medical biology. However, with the gradual development of 3D printing, the original technology of 3D printer has not been further improved, especially the development of FDM technology. It can be said that there is basically no technical breakthrough. However, some enterprises are keen on one thing: big, bigger! With the slogan of Apple, why is it big. Big, just fine? As we all know,…

First of all, I want to give you an idea: not all models can be used for 3D printing. The various online game character models look beautiful, but many of them can't be used. Why? Because the purpose of designer modeling is not to be used for 3D printing, many places do not design according to the requirements of 3D printing models. 2. Optimized design with less support The pain of adding support and removing support is only known through personal experience, and after removing support, it will still leave a very ugly mark on the model, and the process…

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…

What are the surface treatment methods of aluminum alloy die castings? According to the quick screen editor, the commonly used technologies are: Aluminum phosphating, aluminum alkaline electrolytic polishing process, aluminum and aluminum alloy environmental protection chemical polishing, aluminum and its alloy electrochemical surface strengthening treatment, and YL112 aluminum alloy surface treatment process. The details are as follows: 1. Aluminum phosphating The accelerator, fluoride, Mn2 +, Ni2 +, Zn2 +, PO4 were studied in detail by means of SEM, XRD, potential time curve and film weight change; And Fe2 + on the phosphating process of aluminum. Research shows: Guanidine nitrate has…

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…
