Product features and specifications

Basic specifications and features of the product

High anti-vibration effect with special body design

Unequal lead insert arrangement

β1≠β2≠β3

Unequal division

a1 ≠ a2

Anti-vibration effect of special body suppresses chatter

Tool: PSFL09R050M27-4-78 (ø50 × 4 flutes) work material: Ti-6Al-4V
Cutting conditions
Vc = 60 m/min (n = 382 min^-1) Vf = 230 mm/min (fz = 0.15 mm/t)
ap = 78 mm ae = 10 mm Water-soluble cutting oil (internal lubrication)
Machine used: Horizontal machining center (BT50)

Achieves high-efficiency machining with 1.5 times the efficiency by suppressing chatter

Tool: PSFL12R063M27-4-100 (ø63 × 4 flutes) work material: FC300
Cutting conditions
Vc (PSFL) = 180 m/min (n = 910 min^-1) Vf (PSFL) = 910 mm/min (fz = 0.25 mm/t)
Vc (other manufacturer's product) = 150 m/min (n = 758 min^-1) Vf (other company's product) = 606 mm/min (fz = 0.2 mm/t)
ap = 60 mm ae = 7 mm air blow
Machine used: Horizontal machining center (BT50)

Economical and durable 4-corner insert

Cutting force is reduced by the sharpness of the 3D chip breaker insert and the large positive rake angle

• Cutting edge shape designed with an emphasis on sharpness
• Low resistance positive rake angle

Common insert

09 size can use the same insert as PSF and is easy to manage

The above figures show general values at actual cutting speed. Please adjust appropriately according to the cutting environment.

Guideline for changing conditions when the depth of cut is changed

Compatible work material

Recommended material for each work material

◎: First recommended material,○: Second recommended material

NM: For aluminum alloy; GL: For light cutting; GM: For medium cutting; GR: For heavy cutting
The chart is based on conditions at a depth of cut (ap) 1.1 to 1.5 D and a width of cut (ae) 0.1 D or less.
