The production and processing of end mills
The production and processing of end mills is a complex and precise craft that involves multiple steps and technologies.
The manufacturing of end mills typically begins with the selection of appropriate materials, such as high-speed steel (HSS) or hard alloys. Blanking refers to the process of cutting raw materials to the required size according to design specifications, and this step is crucial for subsequent processing.
For end mills made of high-speed steel material, forging is a key step that helps achieve a uniform microstructure and enhance the mechanical properties of the material. End mills after forging usually require annealing treatment to relieve internal stresses, reduce hardness, and prepare for subsequent machining and heat treatment. The forged and heat-treated end mill blanks will undergo mechanical processing, such as turning and drilling, to achieve more precise dimensions and shapes. Grinding is an essential step in the manufacturing of end mills, ensuring that the tools have precise geometric shapes and sharp cutting edges. For hard alloy end mills, precision grinding is typically carried out using CNC tool grinders.
To enhance the performance of end mills, such as wear resistance and anti-adhesion, special coatings are often applied to the blades, such as physical or chemical vapor deposition (PVD or CVD). For end mills that rotate at high speeds, dynamic balancing is key to ensuring their stable operation. Dynamic balancing adjustments can reduce vibration, improve machining accuracy, and extend the tool's lifespan.
In the final stage of end mill production and processing, the tools are subjected to quality inspections to ensure they meet design and performance requirements. Qualified end mills are then individually packaged and prepared for shipment according to costumers' requirements.
The above steps summarize the production and processing process of "DouRuy" end mills from raw materials to finished products. Each step requires precise control and professional techniques to ensure that the performance and quality of the end mills meet the high standards of industrial applications.
