O/T New Ball nose cutter

[Teh Bear without Brains kinda idiot]

Hello ,humans !

Look at this

New Ball Nose cutter R218.20

Seco Tools is introducing a new Ball Nose cutter, R218.20, in the diameter range 16-50 mm. This cutter can handle very high feed rates thanks to a rigid design and the two effective numbers of teeth.

 

 

The insert and body strength gives the cutter maximum safety and reliability, which makes it suitable for use in unmanned production. R218.20 can handle very high feed rates which gives it very good productivity on modern machine tools. It is also cost-effective under peak performance thanks to the insert and body strength. The new Ball Nose cutter R218.20 is a versatile cutter and can be used from semi-finishing to heavy roughing operations.

The cutters have a unique seating with tenon to avoid stress on the locking screw, and a chip space with a big radius to make the cutter strong in the centre.

 

The insert edge is "S" curved to reduce cutting forces, and has a constant cutting rake all along the edge. Reinforcement in the centre makes it breakage resistant.

 

 

 

Cutters are available in Cylindrical shank, Cylindrical/Weldon shank, Seco Weldon shank, Morse taper, Weldon pin drive shank (dia 50 mm) and Combimaster heads, with different reach lengths.

It looks the same as all the rest, So what is new?

Did you copy and paste this straight form the catalogue?

[Teh Bear without Brains kinda idiot]

You can use insert twice ,the S form of the insert will less spindel load - that`s for a start .

And you will have a possibility to use them in bull-nose tools too

Combimaster heads

~~~~~~~~~~~~~~`

instead of regular round inserts ,which are less rigid and have less space for chips

 

For me this is new

This is Iscar line ,just to compare

Corey ?

Have you tried it ?

What are S and f for mold steels ?

[mold100]

I used the 1 incher I would rough with the 2" Coromill then go to it with ball 3800 rpms 80 to 100 ipms.Contour and paralle.(Also this was in a makino v55, my fadal could not do that)

What you are seeing is the convergence of the tooling "Marketers" (As opposed to manufacturers). One day there will be three (Sandvik, Iscar and Kennametal) but for now, here is how it goes.

 

Sandvik Corporation owns Seco, Vallenite and Sandvik Coromant. These ball nose cutters are manufactured in France by Safety (Saff e tee) and are "Marketed" by Coromant, Seco and Valenite under their own labels. The tools are exactly the same and I buy direct thru the old Safety distribution channel at a lower price than the Sandvik Label.

 

Another tool that is marketed the Sandvik group the same is the Araf ballmilling tools - similar to the Millstar style of a single round insert.

 

Hope this helps winnie - wouldn't want too many "Bees" to try and sell you the same honey - if you get what I am saying.

Interesting info .

Also :

I heard Iskar bought Y-G

[jctjct]

Iscar has a new cutter very similar to this called Drop-Mill. It is pretty impressive for semi-finishing, but inserts are pricey.

also SECO owns Jabro - a line of high performance solid carbide tools
