MOLDINO - TD4N type : Radius Mill TD4N | JSR GROUP

 

 

TD4N type

 

 

Features 01  Reduces uncut remnants on work pieces

The cutting edge shape was reviewed for TD4N so that remains 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 remains that cannot be checked on CAM and become more work for the next process.

 

Features 02  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 03  Large tip diameter for excellent handling
Compared to conventional high-feed tools, TD4N has a large tip diameter, which suppresses the generation of remains 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 04  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.

Crushed cutting chips

If cutting chips are not discharged well, jamming of the cutting chips between the tool and wall occur, which can become the cause of sudden damage such as chipping, etc.

Cutting chips which were discharged well

Good chip discharge characteristics are achieved by providing large chip pockets and controlling the chip discharge direction.
