Practical examples

Example #1
Part: Fitting
Material: SUS304 / X5CrNi18-10
Tolholder: JSYJ2CR1212X10
Insert: YCGT100202MF-JS
Grade: SH7025
Cutting conditions: Vc = 85 m/min
f = 0.03 mm/rev
ap = 0.075 mm
Application: External turning
Coolant: Wet

Traditionally, machining the thread-end taper requires a dedicated inser t shape. YCGT performs this operation while delivering 1.75 times longer tool life.

Example #2
Part: Shaft
Material: S45C / C45
Tolholder: QC12-JSYJ2CR10-CHP
Insert: YCGT100202MF-JS
Grade: SH7025
Cutting conditions: Vc = 70 m/min
f = 0.02 mm/rev
ap = 0.3 mm
Application: External turning
Coolant: Wet

Conventionally, two different tools were required for external turning and profiling.
YCGT integrates both functions into a single tool.

Example #3
Part: Pulley
Material: SCM415
Tolholder: AVVNN2525M16-A
Insert: YNMG160404-ZM
Grade: GT9530
Cutting conditions: Vc = 250 m/min
f = 0.5 mm/rev
ap = 0.1 – 0.2 mm
Application: External turning
Coolant: Wet

Chip control was drastically inproved against conventional grooving tool. 1.25 times longer tool life achieved.

Example #4
Part: Automotive part
Material: SACM645
Tolholder: A16Q-SYUBR11-D200
Insert: YWMT11T204-ZF
Grade: T9215
Cutting conditions: Vc = 100 m/min
f = 0.5 mm/rev
ap = 0.2 mm
Application: Internal turning
Coolant: Wet

Chip control and surface finish are improved drastically when internal turning.
