COGO TOOL's technical info4 - Selection and Usage

■ Proper selection of the End Mill
For use the End mill more economically and efficiently, select the proper End Mill by considering the shape and hardness of work mate-rial and processing efficiency.
Therefore, the diameter, number of the flute, length of the flute, helix angle and materials of the End Mill should be considered.


  • Raw Material of Toll

For the cutting process from the structural steel, nonferrous materials to cast iron, Cobalt 8% HSS(SKH 59 grades) is the best. For more efficient processing and longer durability, selct the coating End Mill, power metallurgy HSS End Mill or the Carbide End Mill.


  • Number of the flute
important factor of the performance of the End Mill
-2flutes : By the wider chip pocket, the chip can be discharged smoothly but the section size of the tool is narrow so its rigidity reduces. It can be used in the slotting.
-4flutes:By the narrower chip pocket, the chip cannot be discharged freely but the section size of the tool is wide to its rigidity expands. It can be used in the side cutting mainly.

  • Length of the cutting part
If working by decreasing the cutting part length, the rigidity can be increased. The projection length of End Mill influences in the rigidity so avoid to increase the length unnecessarily.

COGO TOOL's technical info3

  • Upward and Downward cutting

Comparison 
Back lash of the feed screw
No influence in cutting
The black lash has to be removed completely
Rigidity of the structure
No influence in case of 
the low rigidity   
The high rigidity is needed for the stroke
Durability of the cutting edge
It’s disadvantageous because it lifts the structure upward and the force goes up
Because the force comes down and presses the structure but when it’s not installed completely, the materials can be flown to the sky with that force.
Influence of the bulit-up edge
Shorter durability of the flank wear with the fiction during insertion
Longer durability
Friction resistance
Rather low
The friction force during the insertion is low but its stroke can be high to the downward
Finished surface
For the higher friction resistance during insertion, the force to lift upward is high
There is no glossy surface but the rotation resistance during the low feed cannot be occurred so all the surface is rather glossy and even. The finished surface is more glossy than the upward cutting but in case of the soft materials the finished surface can be worsened.
Cutting condition
It raises the cutting speed and feed more than the upward cutting. It’s possible to cut the heavy materials
  • Coolant
The coolant is to improve the lubrication, cooling and anti-fusion property so increase the durability and grade of the processed surface, and removes the cutting heat, reduces the generation power and add the productivity like the cleansing effect of the micro chips.

COGO TOOL - Midas Drilling Video

COGOTOOLS' drilling video.


MIDAS KTD DRILLING VIDEO
(KTD-30040D)

-Drilling diameters are from 12.5mm to 50mm and a various of drilling depth is available(2D,3D and 4D).
-Cost-dffect by using 4-edge inset.
-A wide range of drilling such as double plates and inclined surface is possible.
-The especially treated surface of body makes wear resistance much better and tool life much longer.
