JIS PRML TI

Z-PRO

Premium Thread Mills for Heat-Resistant Alloys

Specification

Coating <2D

Product Features

  • The same PRML TI can process right and left hand internal threads by using the helical interpolating process.
  • This is most suitable for tapping heat-resistant alloys.
  • Because it cuts at the first thread, it won't make the internal threads taper and the internal threads become highly accurate.
  • When cutting, the load on the tool is small and the tool life is long.
  • Cutting resistance is reduced by turning the tool counterclockwise and machining it from the top to the bottom with 1 pass cutting.

1) These cutting conditions are based on water soluble cutting fluid. Depending on the condition of the cutting fluid, satisfactory performance may not be delivered. 2) Being careful of the nozzle position, supply enough oil obliquely from above the tool during use. ＊ Formulas for revolution speed and feed speed of tool Revolution speed (min-1) = 1000 x Cutting speed / 3.14 / Cutter dia. (Dc) Feed speed (mm/min) = fz x No. of flutes x Revolution speed x (Nominal dia. of internal thread - Cutter dia. (Dc)) / Nominal dia. of internal thread
