Solid Carbide DrillThe design and manufacturing of the material usually includes the following steps: First, design according to the specific processing requirements and the hardness, toughness and other characteristics of the material to be processed. The design includes parameters such as drill shape, number of edges, edge angle, edge diameter, pitch, etc. Then select suitable cemented carbide materials according to design requirements and prepare them into blanks through powder metallurgy processes. The next processing process includes sintering, forming, precision grinding, etc. to ensure the accuracy and wear resistance of the drill bit. Finally, surface treatment is usually used to improve the wear resistance and thermal stability of the drill bit by coating and other methods.
In the next few years, with the development of the manufacturing industry, the design and manufacturing of cemented carbide drill bits will pay more attention to the application of digital intelligent technology to meet customized processing needs and improve processing efficiency. At the same time, with the continuous development of new materials and processes, cemented carbide bits will pay more attention to innovation to adapt to the processing and special processing needs of new materials.
In the design and manufacturing of integrated cemented carbide drills, technical parameters such as rake angle, negative rake angle, edge band, edge width, and angle will directly affect the use effect of the drill. Rake angle refers to the angle of entry of the cutting edge to the workpiece, which is usually determined based on the hardness and toughness of the processed material; negative rake angle is used to improve the strength and wear resistance of the cutting edge; edge band refers to the cutting edge on the cutting edge; edge width determines the cutting area during cutting; edge angle affects the shape of the chip and the size of the cutting force.
In the future, the design and manufacturing of cemented carbide drill bits will pay more attention to the application of digital intelligent technology to more accurately control these technical parameters to meet customized processing needs and improve processing efficiency. At the same time, the development of new materials and processes will also promote the continuous innovation of technical parameters of cemented carbide drill bits and adapt to the processing needs of new materials.
Solid Carbide DrillRake angle design: Rake angle is the angle between the top of the drill blade and the feed direction. Under normal circumstances, the larger the rake angle, the smaller the bit feed angle, which is easy to generate cutting force and heat, and the speed will also be reduced. Therefore, generallyTungsten steel drill bitThe rake angle is generally designed to be around 118 degrees to ensure cutting efficiency and drill life.Too small a rake angle increases the friction between the drill bit and the workpiece, which may lead to heat accumulation and premature wear of the drill bit. Appropriate increase in rake angle can improve cutting efficiency and cutting performance of the drill bit.
Solid Carbide DrillRelief angle design: Relief angle is the angle between the bottom of the drill blade and the feed direction. The back angle is generally between 8 degrees and 15 degrees. If the relief angle is too small, the drill bit may easily break; if the relief angle is too large, it will increase the frictional resistance of the drill bit, resulting in increased cutting force and reduced speed. Too small the back angle may make it difficult to discharge chips and increase the contact pressure between the drill bit and the workpiece. Too large the back angle may weaken the cutting edge of the drill bit.
Solid Carbide DrillEdge cutting angle: The edge cutting angle is generally between 25 degrees and 30 degrees. If the angle is too small, edge wear or edge fracture will easily occur; if the angle is too large, excessive vibration and heat will easily occur, and cutting efficiency and life will also be reduced.
Solid Carbide DrillBlade angle: The blade angle is the angle between the cutting surface of the blade and the axis of the drill bit. In general, the smaller the edge angle, the greater the cutting force, but the feed speed will also increase. Therefore, the edge angle is generally designed between 12 degrees and 15 degrees to achieve the best cutting effect and life.
Solid Carbide DrillMain effect of blade angledrill bitAbility to enter and exit. A larger rake angle reduces cutting resistance and makes it easier for the drill to enter and exit the material. Generally, the blade angle is between 10° and 20°.
Solid Carbide DrillThe blade is a spiral groove on the drill bit that is used to expel chips. The geometry, width and depth of the edge all affect cutting performance. The wider the blade belt, the larger the space for chip removal, but it will also increase the wear of the drill bit. The depth of the blade needs to match the diameter of the drill bit to ensure effective chip ejection.
Through the design of the above standards, the cutting efficiency and life of tungsten steel drill bits can be effectively improved, and the processing quality and work efficiency of workpieces can be improved.
