The two parties jointly develop, design, and produce teams, advanced equipment, and continuously innovate and improve technical strength. They are committed to mutual cooperation, guided by technical services, and form a form of mutual reliance in the industrial chain to solve various processing problems for processing and manufacturing companies. Application Application In-depth into various industries (I) Mechanical manufacturing In the field of mechanical manufacturing, tungsten steel milling cutters are a powerful assistant to improve the processing accuracy and surface quality of parts. . Taking the manufacture of automobile engines as an example, various parts in the engine, such as crankshafts, cylinder blocks, cylinder heads, etc., have extremely high requirements for processing accuracy. The crankshaft journal requires precise dimensional accuracy and extremely low surface roughness to ensure the smooth operation of the engine. With its excellent hardness and wear resistance, tungsten steel milling cutters can maintain stable cutting performance during the processing process and accurately cut out the required dimensions and surface finish. When processing the complex cavity of the cylinder block, the multi-edge design and good chip removal performance of the tungsten steel milling cutter make the processing efficient and stable, which can meet the needs of mass production and provide strong support for the high-quality development of the automobile manufacturing industry.
(ii) Mold processing
The shapes of molds are often complex and diverse, and the requirements for processing accuracy and surface quality are extremely high. . Tungsten steel milling cutters can perfectly meet these demanding requirements in mold processing. In the processing of injection molds, it is often necessary to produce various complex cavities and cores to form various plastic products. Tungsten steel milling cutters can accurately process the fine structure and complex curved surfaces of the mold through high-speed milling, ensuring the molding accuracy and surface quality of plastic products. Its special grinding surface and coating design not only improves the cutting efficiency, but also further extends the service life of the tool and reduces the cost of mold processing. In the processing of die-casting molds, since the mold material is usually a high-strength alloy, it is difficult for ordinary tools to process effectively, while tungsten steel milling cutters can smoothly complete the processing tasks with their high hardness and wear resistance, ensuring the quality and precision of the mold.
(III) Electronic equipment manufacturing
The electronic equipment manufacturing industry has reached the micron or even nanometer level for the precision requirements of parts and components, and tungsten steel milling cutters play a vital role in this field . In the manufacturing process of smart phones, various electronic components on the motherboard, such as chips, resistors, capacitors, etc., need to be precisely processed and installed. Tungsten steel milling cutters can be used to process microstructures such as chip pins and circuit board micropores. Their high-precision cutting ability can ensure the dimensional accuracy and connection reliability of electronic components, thereby ensuring the stable performance of smart phones. In the manufacture of tablet computers, the frame of the display screen, internal structural parts, etc. are also inseparable from the precision processing of tungsten steel milling cutters. It can perform fine cutting on various metal and non-metallic materials to meet the requirements of the electronic equipment manufacturing industry for thin and high-performance products.
5. Selection strategy to avoid pitfalls
(I) Pay attention to materials and grades
The material and grade of tungsten steel milling cutters have a decisive influence on their performance. Generally, imported cemented carbide materials are often superior to domestic materials in quality and performance, and the price is relatively high, generally 2-3 times that of domestic materials. Different grades also have large differences in composition and performance, and the price will naturally be different. Take YT15 brand tungsten steel as an example. It contains 15% titanium carbide (TiC), has high hardness and wear resistance, and is suitable for processing tough materials such as steel; while YG8 brand tungsten steel contains a high cobalt content and has better toughness, which is more suitable for processing brittle materials such as cast iron and non-ferrous metals. When choosing a tungsten steel milling cutter, it is necessary to carefully select a milling cutter of suitable material and brand according to the specific processing materials and processing requirements to ensure the processing effect and tool life.
(II) Check the appearance details
The appearance details are an important basis for judging the quality of tungsten steel milling cutters. First, check whether the angle of the tool is accurate, which is directly related to the cutting performance and processing accuracy of the milling cutter. Milling cutters with inaccurate angles may have problems such as uneven cutting force and increased tool wear during the cutting process, affecting the processing quality. Surface brightness is also an important indicator. The surface of a high-quality tungsten steel milling cutter should be smooth and bright, without obvious defects and scratches. The laser printing should be clear and complete, and can accurately reflect the brand, model, specifications and other information of the tool. The front end of the milling cutter should be flat, and the teeth should be neat and uniform, without chipping, missing teeth, etc. The back angle blade should be uniform and consistent, without obvious differences. At the same time, carefully check whether the tool has defects such as burrs and cracks. These defects will seriously affect the strength and service life of the tool, and may cause the tool to break suddenly during use, causing safety accidents.
(III) Consider clamping and vibration factors
The clamping method and vibration of the end mill have an important impact on the processing process. At present, most end mills used in machining centers are clamped by spring clamps, and are in a cantilever state when used. During the milling process, sometimes the end mill may gradually extend from the tool holder or even fall off completely. This is usually because there is an oil film between the inner hole of the tool holder and the outer diameter of the end mill shank, resulting in insufficient clamping force. In order to avoid this situation, before clamping the end mill, the end mill shank and the inner hole of the tool holder should be cleaned with cleaning fluid, and then clamped after drying. When the diameter of the end mill is large, even if the shank and the tool holder are very clean, the tool may still fall off. At this time, a shank with a flattened notch and a corresponding side locking method should be selected to ensure that the tool is firmly clamped.
There is a small gap between the end mill and the tool holder, which may cause the tool to vibrate during the processing. Vibration will make the cutting amount of the circumferential edge of the end mill uneven, and the cutting and expansion amount will increase compared to the original value, affecting the processing accuracy and tool life. When the width of the machined groove is small, the tool can be vibrated purposefully to increase the cutting and expansion amount to obtain the required groove width, but the maximum amplitude of the end mill should be limited to less than 0.02mm, otherwise stable cutting cannot be performed. In normal processing, the smaller the vibration of the end mill, the better. When tool vibration occurs, consider reducing the cutting speed and feed speed. If there is still a large vibration after both have been reduced by 40%, consider reducing the cutting amount. If resonance occurs in the machining system, it may be caused by factors such as excessive cutting speed, low feed speed, insufficient rigidity of the tool system, insufficient clamping force of the workpiece, and workpiece shape or clamping method. At this time, measures such as adjusting the cutting amount, increasing the rigidity of the tool system, and increasing the feed speed should be taken to reduce the impact of vibration on machining.
