Thread Cutting Technology

Clamping TechnologyCutting of keyways
With one step cutting process(full size cutters)
Recommendation:2-fluted cutters
Keyway:20 P9 ( )-0,022-0,074
Cutter:
20 e8 ( )-0,040-0,073
Advantages:
Time saving, because keyway length
= cutting length
Disadvantages: Keyway walls are not perpendicular (cutter displacement)
When the cutter is worn out reduction of tool dia.
the tolerance of the keyway can no longer be achieved
cutter must be exchanged, even if the maximum tool life
hasnt been reached
reground cutters are not suitable for one step process
Cutting example:
Keyway 20 P9 x 90Milling cutter type: 2300.020 (2-flutes)Material of workpiece: 42 CrMo 4 V, Rm = 850 N/mm2
Cutting conditions: ap = 10 mm, vc = 30 m/min, n = 477 min-1
Drilling feed: fz = 0,029 mm, vf= 30 mm/minCutting feed: fz = 0,073 mm, vf= 70 mm/min
Cutting time: approx. 80 sec./keyway
With three step cutting process(under size cutters)
Recommendation:3-fluted cutters
Keyway:20 P9 ( )-0,022-0,074
Cutter:
19,7 h10 ( )-0-0,084
Advantages:
Keyway walls are perpendicular
When the cutter is worn out reduction of the tool dia.
the tolerance of the keyway can be reached by
radial resetting of the cutter the full tool life of
the cutter can be used
reground cutters can be used again
Disadvantages: more time is needed because of longer process
only possible on CNC machines
Cutting example:Keyway 20 P9 x 90Milling cutter type: 2310.0197 (3-flutes)Material of workpiece: 42 CrMo 4 V, Rm = 850 N/mm2
Cutting conditions: ap = 10 mm, vc = 30 m/min, n = 477 min-1
Drilling feed: fz = 0,029 mm, vf= 40 mm/minCutting feed: fz = 0,073 mm, vf= 105 mm/minCutting feed: fz = 0,200 mm, vf= 286 mm/min
Cutting time: approx. 85 sec./keyway
