Publish Time: 2025-03-18
Coated tungsten steel milling cutter, a highly respected tool in the field of mechanical processing, has become the preferred choice of many processing industries for its excellent performance and durability. It is made of hard tungsten steel alloy raw materials and combined with the exquisite craftsmanship of German Walter machine tools. Whether it is precision, toughness or wear resistance, it has reached an extremely high level.Advantages of hard tungsten steel alloy raw materialsHard tungsten steel alloy is one of the core materials of tungsten steel milling cutters. Its main components include metal carbides such as tungsten carbide (WC) and cobalt carbide (Co). These carbides are combined together by metal binders to form a structure with high hardness and excellent toughness. Hard tungsten steel alloy has the following significant advantages:High hardness: The hardness of hard tungsten steel is very high, close to diamond, and can easily cope with various high-strength and high-hardness material processing requirements.Wear resistance: Even in high temperature environments (such as 500℃ or even 1000℃), the hardness of hard tungsten steel remains very high. This allows it to maintain good cutting performance during long-term use.Heat resistance: Hard tungsten steel can still maintain its physical properties under high temperature conditions and is not easy to deform or damage, which provides a guarantee for high-speed processing.Corrosion resistance: Due to its stable chemical composition, hard tungsten steel has excellent corrosion resistance and can be used for a long time in a variety of complex environments.Precision manufacturing of Walter machine tools in GermanySince its establishment in 1919, Walter has been a leader in the global precision tool manufacturing field. Headquartered in Tübingen, Germany, Walter is not only famous for its innovative technology, but also has rich production experience and advanced manufacturing facilities. The coated tungsten steel milling cutters produced by Walter are widely used in various mechanical processing fields due to their high quality and excellent performance. The characteristics of Walter machine tools include:High precision: Walter machine tools strictly control every detail during the production process to ensure that the size and shape of each milling cutter are accurate.High rigidity: The machine tool structure is reasonably designed and can remain stable under high load, which is crucial to improving the service life and processing quality of the milling cutter.Advanced technology: Walter uses advanced coating technology and processing technology to make the surface of the milling cutter smoother and more wear-resistant, while extending its service life.Application and advantages of coating technologyCoating technology is a key step in improving the performance of tungsten steel milling cutters. The coating not only increases the wear resistance and toughness of the milling cutter, but also significantly improves its service life and processing efficiency. Common coating methods include chemical vapor deposition (CVD) and physical vapor deposition (PVD). For hard tungsten steel milling cutters, CVD coating is usually used. This method can be carried out under high temperature conditions (about 1000℃), making the coating more firmly bonded to the substrate and the effect more lasting.The main functions of the coating include:Improve wear resistance: The coating can greatly enhance the wear resistance of the tool, so that it remains sharp after long-term use and reduces the frequency of replacement.Improve toughness: High-quality coatings can increase the toughness of the milling cutter, reduce the risk of chipping and fracture, and improve the stability of the processing process.Reduce friction: The coating surface is smooth, which can effectively reduce friction during cutting and improve processing accuracy and surface quality.Smooth chip removal: The special coating treatment also makes it easier to remove chips, avoiding secondary cutting or tool damage caused by chip blockage.Unique design featuresCoated tungsten steel milling cutters are not only refined in material and manufacturing process, but also ingenious in design. The following are some unique design features of coated tungsten steel milling cutters:Ball head profile: Milling cutters with ball head design are suitable for processing complex curved surfaces, which can achieve higher precision and better surface quality.High R profile: The high R profile design helps to reduce vibration during processing, improve processing stability and tool life.Unique helix angle: Coated tungsten steel milling cutters are usually designed with a special helix angle, which not only improves cutting efficiency, but also makes chip removal smoother, thereby reducing heat accumulation and tool wear.Longer cutting edge: Compared with traditional milling cutters, coated tungsten steel milling cutters have longer cutting edges, which means that more material can be removed per cut, thereby improving processing efficiency.Optimized rigidity: By optimizing the tool structure and material ratio, coated tungsten steel milling cutters have better rigidity and can remain stable under high load conditions.Wide range of application scenariosDue to its excellent performance and diverse design features, coated tungsten steel milling cutters are widely used in the finishing and semi-finishing processes of various materials. Especially in the processing of mold steel, pre-hardened steel, 45 steel and ordinary steel before heat treatment (below 55HRC). Specific application scenarios include:Mold manufacturing: In the mold manufacturing process, coated tungsten steel milling cutters can achieve high-precision and high-surface quality processing to ensure that the size and appearance of the mold meet the design requirements.Mechanical parts: Used to process various high-precision mechanical parts, such as aerospace parts, automobile engine parts, etc., to ensure their dimensional accuracy and surface finish.General processing: Suitable for the processing of ordinary steel and pre-hardened steel, which can meet the needs of most industrial processing.Efficient production: Due to its high rigidity and optimized design, coated tungsten steel milling cutters can complete the removal of a large amount of material in a short time, which is suitable for mass production.Coated tungsten steel milling cutters have become an indispensable and important tool in the field of modern mechanical processing with their excellent performance and wide application prospects. Using hard tungsten steel alloy as raw material, combined with the precision manufacturing process and advanced coating technology of Walter machine tools in Germany, this milling cutter performs well in terms of accuracy, toughness, wear resistance and rigidity. Its unique design and optimized performance enable it to play an important role in the finishing and semi-finishing of various materials, especially in the processing of mold steel before heat treatment, pre-hardened steel, 45 steel and ordinary steel, showing unparalleled advantages. With the continuous advancement of technology and the expansion of application fields, coated tungsten steel milling cutters will surely play a more important role in the future mechanical processing field.
