Stock removing velocity and cutting fluid on the tapping for the materials have been studied in the paper, and thus reasonable tapping conditions for practical working could be selected.
With evolution, most of NTN's effort has been changed into the manufacture and sales of bearings, constant velocity Joints (CVJ) and precision machinery since the joint-stock reform in 1934.
