Te c h n o l o g y Reduces the risk of breaking off inside By using a tool with a diameter smaller than the inside diameter of the thread, cutting chips are smaller and chip evacuation is improved. The risk of the tool breaking off inside the hole is reduced as a result. One tool - various types of thread milling Right hand, left-hand and fine thread milling can be performed by just changing the NC program. The nominal diameters of the coarse threads and fine threads that can be processed with the same tool are different. (Example: For ET-1.25-16-PN, coarse thread is M8 × P1.25 and fine thread...

©Epoch Thread Mill is an only for threading the inside of holes. ©The above cutting conditions are for the nominal diameters stated in the table. Cutting conditions for other nominal diameters should be calculated taking into consideration the cautions on use (p.15). ©The machinery should be a machining center equipped with NC (numerical control) equipment having a helical interpolation function. ©The feed rate stated in the above conditions table is the feed rate at the tool center during threading. In addition, the per-tooth feed rate is the numerical value at the cutting point. ©Since there...

Nominal diameter which requires pilot hole can not be used without larger pilot hole than the values shown in the table. O Cautions when using Epoch D Thread Mill for PT, NPT threads Outer diameter line C/e taper line passing through the apex of thread ridge) Since the reference tool diameter Dc and the tool tip diameter Dc' are different, it is necessary to correct the nominal diameter D1 and program. The nominal diameter D1 corresponds to the reference...
