bookShop standing accuracyRH4,RH5,RH6,RH7,RH8 Price consistency with different precision,Specific accuracy please contact the shopkeeper 13538304172
The RH4 of RH4-P is the precision (tolerance) of this product. P represents the sharp point of product and is usually suitable for through hole tapping. B represents the product for flat head, usually suitable for blind hole attack, and can also be used for through hole tapping.
TOSG extrusion wire tapping standing accuracy - flat head class: RH4B, RH5B, RH6B, RH7B, RH8B; pointed class: RH4P, RH5P, RH6P, RH7P, RH8P
General criteria for selection of RH4, RH5, RH6, the product needs electroplating, will choose a larger precision RH7, RH8
The surface treatment of tap is different the price is different, mainly in titanium processing, oxidation treatment and plating TICN. For details, please contact the shopkeeper 13538304172
Extrusion tap is a new type of machining internal thread with metal plastic deformation principleThread cutterExtrusion screw tap is a non - chip processing technology, which is especially suitable for low strength and good plasticityCopper alloyAnd aluminum alloy, also can be used for stainless steel and low carbon steel and other low hardness, large plastic material tapping, long life.
Extrusion tapIt is a tool for machining internal thread and has grooves along the axial direction. It's called a screw attack. The tap is divided into straight slot tap, spiral groove tap and tap tap according to its shape. Straight groove taps are easy to process with low precision and large output. Generally used in general lathe, drilling machine andTapping machineTheThread machiningThe cutting speed is slow. Spiral groove taps are mostly used in NC machining center drillsBlind holeIt has the advantages of high processing speed, high accuracy, good chip removal and good neutrality. There are grooves in the front of the screw tap, which is used for the machining of the through hole. Most of the taps provided by the tool factory are coated taps, and the service life and cutting performance of the taps are greatly improved compared with the uncoated taps.
The thread surface extruded by extruding tap is high, and the metal fiber of thread is not broken,A chill layer is formed on the surface, It can increase 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.
