Description

   Drill drill into is an important factor in the success of drilling. To ensure good quality of the hole one of the way is to ensure that the workpiece surface and drill drill into the centre of the vertical axis.In addition, indexable drill shallow holes can also adjust the feed, to process convex, concqave, and sloping and irregular drill into the surface.
    Our company supply fast drill, like the XC-function drill,SP disposable rapid drilling tools, WC disposable rapid drilling tools.
Use, high-pressure centre as far as possible the water, increase blade life and BTA sex.
    When used in CNC lathe, the tool centre point to be parallel with the machine spindle centre.
Recommended cutting conditions:
  Initial drilling, to recommend the use of cutting conditions in the middle range, followed by ?in accordance with wear) to adjust the cutting parameters to achieve the best cuttingeffect.
   The above cutting parameter is for 3D,4D drilling tools, the cutting parameter need to decrease *0%.
   Cooling mode using only cold outside, cutting speed should be reduced by *0%.
   It must adpot inner cooling mode for austenitic stainless steel machining.
Drilling on the slope or the part have pre-drilling hole or intersection hole, the drilling feedrate must decrease to 1/3of the recommended data.
