Milling Cutters

Milling Cutters

The milling cutters may have
straight teeth i.e. parallel to the rotation axis 

or in helical shape. 

The angle of helix may be right
hand or left hand which will decide the direction rotation of the cutter for
cutting operation. 
 

A milling cutter may be made of
single piece of steel ot having cutting teeth inserted solid body. 

According to the shape of teeth, milling teeth are
broadly classified as
follows

1.   Plain milling cutters

 Light duty cutters, Heavy duty cutters, Helical cutters


2. Side milling cutters

 Plain cutters,  staggered teeth cutters,   Half cutters,  Interlocking cutters


3. Metal slitting cutters

 Plain cutters,  staggered teeth cutters


4. End milling cutters 

Taper shank cutters, Straight shank cutters, Shell cutters

5. T-slot milling cutters


6. Woodruff key slot milling cutters


  7. Fly cutters


8. Angle milling cutters 

Single angle cutter, Double angle cutters


9. Formed milling cutters

Convex milling cutters,  Concave milling cutters, Corner rounding
milling
cutters, Concave milling cutters, Gear cutters,  Thread milling
cutter


Plain milling cutters

 Plain milling cutters are
cylindrical in shape and have the cutting teeth on their periphery. 
The cutting teeth may be
either straight or helical. 
 Their end faces are either ground
square with the axis or slightly concave to reduce the friction. 
 Hence, by side faces no cutting action is provided. These cutters are used for milling flat surfaces
parallel to the rotation axis. These cutters are available in
diameters from 16 to 160 mm and width range from 20 to 160 mm. 
The different types of plain milling cutters are as
follows :

(a)  Light duty plain milling
cutters 

These cutters are available
upto 20 mm width and carry straight teeth.
