Manufacturer of a well-known stainless steel pipe valve

   Our company originally used in American common bevel pipe thread NPT this year, would like to by the United States Air standard taper pipe thread anpt, for many world famous cutter manufacturers cannot solve, hold try attitude find Rothschild, according to the actual situation of the customer, Rothschild's engineers through the actual simulation to determine the cutting tool geometry design, trial 2 times is solved customers of a long-standing problem, including the overall thread milling cutter and threaded inserts.
Technical difficulties: taper request 3.58-3.86 degrees (the angle error detection in general are at 0.25 degree); dental high 0.97-1.13; tooth top Leveling Height 0.065-0.124; tooth surface roughness Ra0.4; and each tooth top and tooth bottom must take a little flat position, not can be completely circular, flat side of the tooth position and angle required to excessive arc tip are very sharp, both to ensure the smoothness of life but also to ensure that each parameter must be qualified.
