Structure bur empty slot by both entities and retreats debris formed. Edge ribs are on the outer edge of the entities, the ring plane, a small gap between the holding entity part of the drill hole wall to reduce fever. Circling back on their flutes (Flute) side section formed by the horizontal rotation angle called a helix angle (Helix or Flute Angle), the helix angle hour, threaded relatively rare, nearly retired from the crumbs quick, semi-ring machine, but because scrap exit and enter the bur suffered greater resistance, easy warming cause heat build-up edge tip, softening resin is formed in the cavity wall and smear (smear). This helix and back into the drill cuttings suffered the friction angle is large is small and easy to heat resistance, the rubber ring machine, but back material is too slow. ⑵ from the wearing of RPM and drill bit to determine whether it is appropriate Chipload used: (a) if the entity part of the mill's sharp WEB have excessive wear on the drill ring machine, it means too much used Chipolad . (B) If it is found by the verifier drill drilling edge lip (cutting lip) excessive wear, it indicates high RPM conditions generally employed general recommendations adopted as follows: double panel, SFM between about 500-600. For plywood, S.F.M about control between 550-600. Sheung Wan on Hong Friends of lean machine _ _ rubber ring machine automation provided by the Friends of the Shenzhen-Hong Lean Automation Limited.
