MOLDINO - Radius Mill TR4F type | JSR GROUP

 

 

Radius Mill TR4F type

The groundbreaking TR4F type, with cutting depth of 2 mm × 2 mm feed rate per tooth

Overcomes all major issues encountered in mold machining, thanks to TR4F’s three unique features

 

POINT 1 Even with interrupted cutting

 

High chipping resistance

 

 selection of close pitch type 4000 Type
1mm × 2mm
Cutting depth Feed per tooth

 

Tool performance that maximizes the machine’s full capabilities

Rugged cutting, regardless of load, thanks to the unique insert shape

 

【Cutting conditions】TR4F5000 type

Tool dia. :φ63 Cutting speed :vc=130m/min
Depth of cut :ap×ae=2.0×40mm
Work material :Pre-hardened steels （30HRC）
Machine：3-axis MC horizontal type（BT50,37kw）

 

POINT 2 Even with wall face processing

 

Deep cutting 5000 Type

Prevents scraping
2mm × 2mm
Cutting depth Feed per tooth

 

Chip ejection path away from work surface

Prevents scraping due to chip breakage and bending, which often occurs during wall face machining, whether cutting up or down.

【Cutting conditions】TR4F5000 type

Tool dia. :φ63 Cutting speed :vc=100m/min
Feed rate :fz=2.0mm/t Depth of cut :ap×ae=2.0×37.8mm
Work material :Pre-hardened steels （32HRC）

 

POINT 3 Even in chips

 

Minimized  biting risk

 

 

oughing technique achieves “super” high-feed cutting.

Exclusive high-efficiency cutting, resulting from unique insert and body shapes

TR4F type to meet specific challenges posed by high-efficiency cutting

 

Issue 01 Although high-feed cutting is performed for shaping, resulting severe chip clogging and biting may reduce shaping efficiency

 

Proposed solutions

Adopts new body shape to enhance chip removal.
Suppresses chip clogging, even when cutting long overhangs.

Generation of smooth twist-free chips

【Cutting conditions】

Tool dia.：φ63
Cutting speed：vc =130m/min
Feed rate：fz=1.0mm/t
Depth of cut：ap×ae=1.0×38mm
Work material：S50C（220HB）

 

Point Cutting edge designed to control chip flow

 

Optimizes cutting edge design to achieve smooth chip removal flow; keeps chips away from wall surfaces.
Suppresses clogging from the time chip generation starts.

 

 

 

Issue 02 New equipment installed to improve the efficiency of the roughing process.
The goal is to reduce machining times with high-feed cutting. But higher feed rates reduce tool life and keep the machine away from delivering its full potential.

 

Proposed solutions

Developed a unique insert shape. Performs stable machining despite large cutting load generated during high-feed cutting with large cross-sectional and constraint areas.

Adopts unique unequal pitch method to reduce chattering during cutting.

Secures insert strength and constraint force by enlarging cross-sectional and constraint areas even in high-load cutting.

【Cutting conditions】

Tool dia.：φ50, No. of Flutes：4 Flutes,
fz=1.0mm/t, ae=35mm, OH=300mm
Work material：S50C（220HB）

Unequal pitch reduces a vibration, a major factor of chattering.

 

Point Meets the requirements of various applications and steel types.

 

The unique cross-sectional shape and cutting edge design of a single insert meets the needs of a wide range of cutting mod

Diverse lineup of insert grades to meet the demands posed by a wide range of work materials.
