Subject: rotate between 1.2 and 1.4 revolutions вращаются между числом оборотов 1.2 и 1.4 ???Normally cones rotate between 1.2 and 1.4 revolutions per bit revolution. The heel or adjacent heel teeth on the cones primarily determine this ratio. The heel teeth or adjacent heel teeth on cones that are not true rolling have a mechanical advantage over the inner row teeth as the bit is rotated on the bottom of the hole. |
