Pulling Broaching
Pulling broaching is a type of broaching that involves a cylindrical or prismatic shape being pulled through a machine to create a finished shape. Pulling broaching has been used since the late 19th century, when the first broaching machines were made. It has since become a widely used manufacturing process, due to its speed and ability to produce intricate shapes with great accuracy.
The process of pulling broaching starts with the workpiece, which can be made from any material including steel, iron, copper, aluminum, and brass. The workpiece is held between two pulling broaches that are used to pull the material through the broaching machine. As the material is pulled through, a series of cutting teeth in the broach cut the material into the desired shape.
Pulling broaching is used to create a variety of shapes including splines, internal gears, worms, and keyways. The process is extremely accurate and allows for tight tolerances to be achieved. As the material is pulled through the machine, the cutting teeth in the broaches cut the material in a continuous, linear movement. This ensures a smooth finish with no interruption.
The advantages of pulling broaching include increased speed, precision, and accuracy when compared to manual broaching. Pulling broaching machines are also very reliable and require little maintenance, making them a great option for high-volume production. Overall, the pulling broaching process is very efficient and cost effective, making it one of the most popular methods for creating important components.
Pulling broaching is used in many different industries, such as automotive, aerospace, medical, and energy. The incredibly precise and accurate shapes that can be achieved using pulling broaching make it a popular choice for many manufacturers. Pulling broaching machines are currently available in a variety of sizes and designs, to accommodate different needs.
Overall, pulling broaching is an incredibly versatile and efficient manufacturing process that can be used to create a variety of shapes. Not only is it relatively fast and accurate, it also requires little maintenance, making it an ideal choice for many manufacturers. It is a great way to create precision components in a cost-effective and efficient manner.
