ã€China Aluminum Network】 1. Helical wire tapping: For tapping operations where the hole is not cut, the spiral wire tapping will exert its unique cutting effect, cutting high-grade thread quickly and smoothly for you, spiral wire tapping and general The difference in hand tapping is that the ordinary hand taps the groove of the tap into a straight line, and the spiral thread taps into a spiral type. When the spiral thread taps on the tapping, it can be easily turned by the upward rotation of the spiral groove. Iron scraps outside the hole, so as not to remain in the iron or plug in the groove, resulting in the broken cone broken edge cracking, it can increase the life of the wire tapping and cutting a higher precision thread, spiral wire tapping for high toughness Degree of material, not suitable for cast iron, etc. Materials that are finely chopped (N-SP/HC-SP/N+SP, S-SP) Carbide Stone Cutting Tips,Stone Cutting Tips,Ss10 Carbide Tips,Carbide Tips For Stone Cutting Zhuzhou Kerui Cemented Carbide Co., Ltd. , https://www.carbide-china.com
2. Tip wire tapping: For the tapping operation of the through hole being cut, the tip wire tapping will play its unique cutting effect quickly and smoothly for you to cut advanced thread. The tip tapping is mainly used for the thread of various through hole materials. In the cutting operation, the tip tap has the same linear groove as the general hand tap, but there is a specially designed spiral groove at the front end of the cutting part, so that the rotary push cutting is discharged from below the hole, because the tip tap With the function of this rotating discharge chip, in addition to maintaining the cleanliness of the groove to reduce the resistance during cutting, and can avoid the damage of the wire tapping due to cutting blockage, the tip wire tapping can be faster than the common hand tapping. The speed to cut high-precision threads (N-PO/HC-PO/N+PO, S-PO)
3. No iron squeezing wire tapping: No groove tapping is the use of plastic forming method, in the lower hole pressure grinding uplifting the material to form a thread, it will not produce swarf, and will not be damaged due to problems such as chip blocking Thread or wire tapping, grooveless wire tapping is more suitable for material processing with plasticity, for example, aluminum, red copper, zinc, flavonoids in low carbon steel, no groove wire attack two types, standard type N-RS (M6 or less ) (Tip), N-RZ (M8 or more) (Flat), N-RS, N-RZ are teeth according to ISO specifications. They have short teeth and are suitable for tapping in shallow holes. Four teeth in two teeth, the use of unthreaded tap, the need to meet the accuracy requirements and select the size of the hole in order to plastic extrusion high precision, high quality thread 4. Pipe special taps: cast iron pipe taps Specially designed, specifically for cast iron thread tapping, not only in the heat treatment of steel, the angle of the cutting angle, etc., but also has a unique design, and the surface is treated with IN to enhance its wear resistance. Attacks include PF, PS and PT. Each tapping feature:
1. Threaded part is suitable for design, which can reduce the burden of tapping when tapping and increase the life of wire tapping. 2. The high precision of the overall configuration and size of the screw wire tapping is more suitable for precision machining in high speed machining. 3. Screws Attacking Configuration Change (I2Type-I3Type)
two. Overall Performance Analysis 1. According to the actual cutting test results, the service life of the performance-improving type of screw tap is about 30% more than that of the standard product.
2. The elements of the performance-improving screw tap are improved, and it is effective to improve the precision of various performances of the tap.
3. YAMAWA's N+ series taps, the overall configuration of the shape and size of the high precision, the accuracy of the internal thread processing has improved, more in line with the current trend of high-speed processing can be used with some aluminum alloy tapping oil will be more effective Good is mainly aluminum or cast aluminum alloy material products have a strong plasticity, malleability, easy to produce sticking knife during cutting, poor cutting. With the emulsion with good lubrication effect, when the tap is customized, the rake angle of the tap is adjusted to be generally 16 to 20 degrees, which can increase the service life of the tap without increasing the cost.
