Die stocks are tools used in metalworking and machining to hold round or hexagonal dies securely in place. Dies are cutting tools used to create threads on the exterior of a cylindrical workpiece. They are an essential part of the threading process, which involves cutting helical grooves onto the surface of the workpiece to form a screw thread.
Die stocks serve several purposes:
Holding dies in place: Die stocks have a split design with an adjustable screw or handle that allows the dies to be held firmly in position. The dies are inserted into the die stock's slots and tightened securely, ensuring they remain in place during the threading process.
Applying pressure: The adjustable screw or handle on the die stock allows the user to apply the necessary pressure while turning the dies onto the workpiece. This pressure is vital for creating clean and accurate threads.
Guiding the threading process: Die stocks help guide the dies in a straight and even path along the workpiece, ensuring that the threads are cut at the correct pitch and depth. This helps maintain the precision and quality of the threaded finish.
Compatibility: Die stocks are designed to accommodate various sizes of dies, making them versatile tools for creating threads on different workpiece diameters.
Hand threading: Die stocks are commonly used for hand threading applications, where the operator manually turns the dies to cut threads on the workpiece. They are especially useful for smaller-scale threading tasks or when power threading is not feasible.
It's important to note that there are different types of die stocks for specific types of dies, such as round dies for external threads or hexagonal dies for cutting internal threads. Additionally, there are also different designs and sizes of die stocks to accommodate various threading requirements. Proper use of die stocks and dies is essential to achieve accurate and consistent threads on metalwork pieces.
