This leads to high performance of cooling, prevention of welding and wear resistance, and achieves the ⑥ excellent thread surface finish. Chips are smoothly ejected from bored holes to ensure consecutive tapping.■Situations by different pressures ⑦ 1.5 Mpa 3 Mpa 6 Mpa ⑧ ■Tapping Data Tapping conditions [Ｍ6×1] After 500 holes (Can continue to be used) Workpiece Material S50C Excellent thread surface Less damage on the edge Uniform chips’ shape Tapping Length 12mm ⑨ Tapping Speed 20m/minMachinery TypeMachining center, vertical type Tapping Fluid Water soluble cutting fluid Internal Coolant Pressure 1.5MPa Tapping conditions [Ｍ10×1.5]⑩Workpiece MaterialS50C After 420 holes (Can continue to be used)Excellent thread surfaceLess damage on the edgeUniform chips’ shape Tapping Length 20mm Tapping Speed 20m/min Machinery Type Machining center, vertical type Tapping Fluid Water soluble cutting fluid ⑪ Internal Coolant Pressure 1.5MPa JIS ①-19
