Radius Mill TD4N type

Lineup expanded with insert for high-hardness materials

Technology

Features 1 Reduces uncut remnants on work pieces

The cutting edge shape was reviewed for TD4N so that uncut remnants are reduced.
This enables the load on the next process to be reduced by up to 40%compared to
conventional products.

● Since it is difficult to create tool shape definitions in CAM for the complicated cutting edge shapes of high-feed tools, in many cases the tools are used with the definition for a simple R radius tool. The differences between this definition and the actual tool shape result in uncut remnants that cannot be checked on CAM and become more work for the next process.

Features 2 Economical 4-corner inserts with chip breakers for various applications

●By making it possible to use both the front and back sides of inserts, 4 corners can be used. The inserts are provided with a large rake angle which exhibits an excellent cutting force reduction effect even when compared to general positive-shape inserts.

⦿Features of insert breaker

C breaker

Corresponds to our general high-feed-type inserts (EDNW, EPNW,
WDNW, SDNW), and is resistant to chip jamming, vibrations, and crater wear.

B breaker

Enables reduced cutting force when cutting work materials such as
stainless steels, etc. that require free-cutting performance.

⦿Features of insert for high-hardness materials

High-precision G-class insert suppresses dispersion in tool life.
Employs JP4105, a grade for high-hardness materials which provides long
service life for machining 50HRC or harder matrials.

Features 3 Large tip diameter for excellent handling       

●Compared to conventional high-feed tools, TD4N has a
large tip diameter, which suppresses the generation of
uncut remnants which easily occur on the bottom surface
of machined areas. In addition, since the cutting width
(ae) can be set to a large value, this is also effective for
improving machining efficiency.

Features 4 Excellent chip discharge characteristics

●Reduces the occurrence of sudden problems due to jamming of cutting chips. In addition, good chip removal makes it possible to further improve cutting performance.
