1) Recommend honing for machining mold metal and high hardness workpiece.
-The amount of honing shall be less than that of feed per blade.
2) When using end mill without honing, machine for 10 to 30 seconds at feed rate
of less than 0.01 mm/blade and then machine at normal feed rate.
3) Honing is not required for machining aluminium and non-ferrous metal.

[ For Regrinding ]
(1) Concave method
• In case when precise outer diameter dimension is
required.
• In case of aluminium machining.
(2) Flat method
• Excellent machinability
- Applicable to ball end mill and taper end mill.
• Secondary clearance angle work is required.
- When Diameter is large.
(3) Eccentric method
• Excellent toughness and surface roughness.
• Secondary clearance angle work is not required.

[ Trouble Shooting for End Milling ]
Problem Cause Solution
Rupture
• High feed
• High slotting volume
• High protrusion volume
• Worn out of flute
• Longer cutting length
• Reduce feed
• Reduce slotting volume
• Reduce protrusion volume
• Regrind at the beginning
• Reduce cutting length
Wear / Burning
• High speed
• Small rake angle
• High hardness of material
• Reduce speed, Supply enough oil
• Correct to proper rake angle
• Supply Dry > soluble > Non-water soluble oil
and do surface treatment\"
Chattering
• Improper cutting condition
• Lack of strength in machinery and chuck
• Poorly fixed material
• High protrusion volume
• Large clearance of rake angle
• Adjust cutting and feed speed
• Replace machinery and chuck
• Contain a material firmly
• Reduce protrusion volume
• Reduce clearance of rake angle
Defective of
cutting edge
• Hige feed
• Small rake angle
• Chattering occurs
• Poorly sealed material
• High slotting volume
• High protrusion volume
• Lack of strength in machinery
• Reduce feed
• Adjust angle properly
• Reduce Chattering by lowing the number of turning
• Contain a material firmly
• Reduce slotting volume
• Reduce protrusion volume
• Replace machinery
Bad Cutability
• Worn out of cutting edge
• Improper endmill
• Small rake angle
• Regrind at the beginning
• Replace proper endmill
• Correct to proper rake angle
Poor chip emission
• Low injection pressure of the oil
• Small chip pocket
• Worn out of cutting edge
• High slotting volume
• Increase oil volume and pressure
• Use fewer flute endmill or Reduce feed
• Regrind at the beginning
• Reduce slotting volume
Burr on surface
• High feed
• Low speed
• Worn out of cutting edge
• High slotting volume
• Reduce feed
• Speed up
• Regrind at the beginning
• Reduce slotting volume
Incorrect dimension
• Incorrect machinery or chuck
• Incorrect rigidity of machinery or chuck
• longer cutting length
• Fewer number of flutes
• Correct machinery or chuck
• Replace machinery or chuck
• Reduce cutting length
• Replace to larger number of flutes endmill
Fusion
• Lack of oil or affination between tool and
material
• Supply Dry > soluble > Non-water soluble oil
• For alloy steel, use active type non-water soluble oil

※ Please adjust the cutting depth index according to the cutting depth factors of above table.
※ For Rib or Slotting machining process which are not easy for chip ejection, please reduce the cutting depth by 20~30% from the above
cutting condition.
ex) ZSTNB2040-20-10, HRC 55, Rib processing
Cutting depth : 0.32(standard cutting depth) X 0.65 X 0.8 = 0.17mm
※ In actual machining, the condition should be adjusted according to the machining shape, purpose and the machine type.
※ If RPM of the machine is low, the feed rate should be low in the same ratio as RPM.

※ Please adjust the cutting depth index according to the cutting depth factors of above table.
※ In actual machining, the condition should be adjusted according to the machining shape, purpose and machine type.
※ If RPM of the machine is low, the feed rate should be low in the same ratio as RPM.

※ Please adjust the cutting depth index according to the cutting depth factors of above table.
※ In actual machining, the condition should be adjusted according to the machining shape, purpose and machine type.
※ If RPM of the machine is low, the feed rate should be low in the same ratio as RPM.
