First, our store is shipped goods, there are a large number of inventory spot, but extrusion wire tapping has different precision, surface treatment and sharp flat head, so please contact with the shopkeeper before the call or call13018664101
Two, the price of different precision is the same, please rest assured to buy, on the accuracy of the purchase will be described in detail, or before the contact with the shopkeeper, which kind of accuracy is needed
Three, extrusion screw tap and cutting tapping different point without cutting discharge as its characteristics of teeth, and the internal thread processing surface pressure created beautiful appearance. Smooth. Material wire continuous no cutting, thread strength increased by about 30%, the precision is stable, because of the extrusion die of wire diameter psychological endurance, torque high strength, long service life is not easy to break the wire tapping. Materials with great extensibility.
Because of the particularity of extrusion screw tap, screw extrusion and Cutting Tapping the bottom of the same size compared to. So please before use according to the specifications of purchase confirmation right or bottomThe inspection of pass gauge is unqualified.
Four,Extrusion tap is the use of metal plastic deformation principle and internal thread processing of a new type of thread cutting tools, thread extrusion extrusion Taps is a chipless machining process, especially suitable for low strength, good plasticity and copper alloy Aluminum Alloy, can also be used for stainless steel and low carbon steel, low hardness, large plastic materials tapping, long life. The thread surface of the thread extruded by extruding tap is high, the metal fiber of the thread is not broken, and a cold layer is formed on the surface, which can improve the strength and wear resistance of the thread. It fundamentally solves the problem of chip removal in tapping, because of no chips, more conducive to the assembly of threads. It is widely used in electronics and plastics industry.
Five, the first express: Xinfeng (Guangdong province), pass (Guangdong province), from the select SF express, any other specified express please inform the seller, thank you!
