The lubrication or air lowers the temperature by cooling even in dry tapping. It is effective in removing chips from the pilot hole during tapping and prevents chip welding. ⑥ Tapping Data ⑦ Tapping conditions [M6×1] Workpiece Material ADC12 Bored Hole Shape Blind Hole Bored Hole Depth 14mm Tapping Length 12mm ⑧ Tapping Speed 57m/minFeedFully synchronous feed Machinery Type Horizontal machining center Tapping Fluid Water soluble cutting fluid Number of Holes Tapped 240,000 holes ⑨ ⑩ ⑪ JIS ⑤-41
