In modern industrial production, intelligent mechanical processing technology continues to develop, providing efficient and precise solutions for product manufacturing in various fields. Among them, sheet metal tapping, as an important processing technology, has a wide range of applications in stage lighting equipment, automotive mechanical parts, filtration equipment and parts.
Technical points of sheet metal tapping
1. Material selection
Different sheet metal materials have different hardness and toughness, so when performing tapping operations, it is necessary to select appropriate taps and cutting parameters. Marking keywords: sheet metal tapping, material selection, tap matching
For sheet metal materials with lower hardness, such as aluminum alloy, galvanized steel plate, etc., ordinary high-speed steel taps can be selected. For sheet metal materials with higher hardness, such as stainless steel plate, titanium alloy plate, etc., carbide taps need to be selected to improve the efficiency and quality of tapping.
2. Tap selection
The selection of taps directly affects the quality and efficiency of tapping. When selecting taps, factors such as thread specifications, materials, and precision need to be considered.
First, select the appropriate tap according to the thread specifications to be processed. Secondly, the appropriate tap material should be selected according to the characteristics of the sheet metal material. For example, for materials with high viscosity such as stainless steel, taps with coatings should be selected to reduce cutting resistance and wear. In addition, for threaded holes with high precision requirements, taps with higher precision grades should be selected.
3. Cutting parameter setting
Reasonable cutting parameter setting is the key to ensuring the quality of sheet metal tapping. Cutting parameters include cutting speed, feed rate, cutting depth, etc.
The cutting speed should be adjusted according to factors such as the material and diameter of the tap, the hardness of the sheet metal material, etc. Generally speaking, the cutting speed of high-speed steel taps is lower, and the cutting speed of carbide taps is higher. The feed rate should be selected according to the thread specification and the diameter of the tap. Excessive feed rate will cause the tap to break, and too small feed rate will reduce the tapping efficiency. The cutting depth should be controlled according to the thickness and thread specification of the sheet metal material. Generally, it should not be too large to avoid damaging the tap and the sheet metal material.
4. Cooling and lubrication
In the process of sheet metal tapping, cooling and lubrication are very important. Good cooling and lubrication can reduce cutting temperature, reduce tap wear, and improve tapping quality and efficiency.
Cutting fluid or lubricating oil can be used for cooling and lubrication. Cutting fluid can effectively reduce cutting temperature and reduce tool wear, while also cleaning the cutting area and preventing chip accumulation. Lubricating oil can reduce cutting resistance and increase the life of the tap. When selecting cooling lubricants, they should be selected according to the characteristics of sheet metal materials and the requirements of tapping process.
5. Operating skills
Correct operating skills are also an important factor in ensuring the quality of sheet metal tapping. When performing tapping operations, the tap should be kept perpendicular to the sheet metal material to avoid tilting.
At the same time, apply pressure evenly to avoid excessive force that causes the tap to break. During the tapping process, the tap should be withdrawn frequently and the chips should be cleaned to prevent the chips from clogging the threaded hole. In addition, for deeper threaded holes, the segmented tapping method can be used to reduce the load on the tap and improve the tapping quality.
Application of intelligent machining in sheet metal tapping
With the continuous advancement of science and technology, intelligent machining technology has also been widely used in sheet metal tapping. Intelligent tapping machines can realize automated tapping operations and improve production efficiency and quality.

At the same time, the intelligent tapping machine can also realize multi-axis linkage to complete the tapping operation of sheet metal parts with complex shapes.
Precision control
Intelligent machining technology can realize high-precision sheet metal tapping operations. Through sensors and feedback control systems, parameters such as cutting force and torque in the tapping process can be monitored in real time, and cutting parameters can be adjusted to ensure tapping accuracy. In addition, the intelligent tapping machine can also use advanced tool compensation technology to improve the dimensional accuracy and surface quality of threaded holes.
Data management
The intelligent machining system can collect and manage data during the tapping process to provide a basis for the optimization of the production process. Keyword annotation: intelligent machining, sheet metal tapping, data management

As an important machining process, sheet metal tapping is widely used in stage lighting equipment, automotive mechanical parts, filtration equipment and parts. When performing sheet metal tapping operations, it is necessary to pay attention to technical points such as material selection, tap selection, cutting parameter setting, cooling lubrication and operating skills. At the same time, the application of intelligent machining technology has also brought higher efficiency and quality to sheet metal tapping. With the continuous advancement of science and technology, it is believed that sheet metal tapping technology will play an important role in more fields.
