Description of the working principle of the electric tapping machine tapping chuck
The working principle of the electric tapping machine tapping chuck: with 2 positioning pins and 4 screws through the coupling sleeve, the CNC machine tool spindle and the tapping chuck are connected together, so that the connection precision between the tapping chuck and the machine tool is first ensured. Pulling the outer sleeve member to determine the torque required for tapping, the butterfly spring will be pressed by the force, positioned by the steel ball, and the threaded sleeve is connected to tap.
Tapping chucks use the butterfly spring to generate pressure work, H44H check valve, 100x remote control float valve vintage chuck is driven by clutch, the new chuck is linked by steel ball. The clutch fit is tooth-shaped, the positioning is not fine, and it is easy to wear. http://Because only a group of butterfly springs are not evenly loaded, it will not reflect the true force of the butterfly spring and affect the use. The new type of chuck, steel ball is not easy to wear, accurate positioning; each group of 36, a total of 6 sets of contour butterfly springs to ensure uniform force; the scale sleeve is engraved with 200N•m ~ 1400N•m mark, according to the tap The magnitude of the torsion torque is determined by the value of the torsion and locked by the top wire member 39 to prevent loosening.

Methyl Tin Mercaptide stabilizer ProStab - T181
Substitute equivalent to American TM-181-FS
Methyl Tin Stabilizer is an efficient stabilizer used in PVC hot working process. Its stability, transparency, compatibility and weather resistance are all superior to other organotin heat stabilizers. It is widely used in PVC sheet, panel, tubing and blow molding and injection molding products. It can also be used in food packaging, medicine packaging and non-toxic and harmless PVC products. Overseas, PVC products of various foods, medicine packaging and storage, and container and tubing for supplying drinking water with high requirements have all employed methyl tin as stabilizer. Its products boast pure color and luster, less odor vanishing fast and reliable safety performance. With the same effect, the using amount of methyl tin is reduced by 15-20% than that of other similar organotin stabilizers. Our company`s products have passed the ROHS certification.
