Tap is a commonly used thread machining tool, which is mainly used to open internal threads on metal workpieces. The correct use of the tap can improve the work efficiency, ensure the processing quality, and also extend the service life of the tool. Here I will explain the correct use of tap in detail.

First, select the appropriate tap Before using the tap, first of all, according to the workpiece material and thread specifications to select the appropriate tap. Generally speaking, taps can be divided into M, UNC, UNF and other different types according to thread specifications. At the same time, it is also necessary to choose the appropriate tap material according to the workpiece material, such as high-speed steel tap for soft metal, carbide tap for hard metal.

Before using the tap, it is necessary to ensure that the surface of the workpiece is smooth and there is no obvious depression or scratch. Then apply some cutting oil or lubricating oil to the position to be machined to reduce friction and prevent tool damage.

Third, the positioning and clamping of the workpiece to be processed is clamped on the work table, and the tool is used to draw a threaded center line on the surface of the workpiece. Then fix the tap on the tap wrench through the tap mounting hole to ensure that the tap is consistent with the threaded center line of the workpiece.

After determining the position of the thread, slowly rotate the tap with the tap wrench, so that the tap gradually cuts the metal along the center line of the thread. During the cutting process, the appropriate pressure should be maintained to avoid excessive force causing the tap to break. At the same time, be careful not to rotate too fast, so as not to damage the tap or the workpiece.

In the process of processing, the chips and metal chips on the tap should be cleaned regularly to maintain the cutting effect. Brush or compressed air can be used to blow away impurities on the surface to avoid affecting the quality of the next processing.

6, check the thread after the completion of processing, with a measuring tool or thread gauge to check whether the thread size is correct to ensure that the design requirements are met. If the thread quality is not up to standard, it can be reworked with thread repair tools to avoid wasting material and time.

The above is a detailed explanation of the correct use of the tap, hoping to help you better use the tap, improve work efficiency and ensure processing quality. Be sure to pay attention to safety during use to avoid accidents. If you have questions about the use of the tap, you can consult and learn from professionals. I wish you all success in your work!
