Hardbreaker Series - CBN inserts with integrated chipbreaker for improved hard turning productivity

Optimized chipbreaker geometry significantly reduces cutting force imposed on the cutting edge, ensuring long tool

They did a quick swap of material on that one showing ripples. And yes they are the exact same tips in the video both having the same part number BXM10. The difference in chip type is due to different speeds and feed rates.

Very nice, but I don't like how some chips are getting stuck under the tool and dragged.

We just got our first inserts from you guys. Crazy expensive, but if the longevity is there, they’ll be worth every cent. I’m taking .030 cuts into 1020 series steel pipe, working the id, and I’ve done about 90, 6” long, 1.5” diameter tubes, and there’s only the slightest discoloration. Running at 460rpm, and hand crawling the feed about .2mm a second. Looks like it was atomically printed.

Good one. I need better finishing in ID hardness 42 to 45 HRC. We make injection moulds for bobbins. Some cavities are Taper and some are straight. How we achieve such finishing in ID?? Do you have hoarded grade Insert for boring? Please describe me insert number. Our boring length will be 100mm to 300mm. What kind of boring bar we can use to achieve good finishing?

[ultimatemonkey]

I'm a hobby machinist at BEST but it'd damn cool if I could consistently recreate that ripple pattern of the 2nd clip as a finish for non critical things

Do allot of hard turning, these will change my game. Gone by some

[DiTV]

In the same types, and the same cutting condition, this show the different between breaker and non- breaker. Of course that would be great if the cut chips are broken up, right?

[ayatotakema]

I love CBN, Makes the matt red hot if its hard n fast enough

[XJ]

Those are some of the prettiest chatter marks ive ever seen. Is it just me or are they kinda pretty?

[hironoriyokouchi]

Comparison between with chip breaker and without chip breaker

[Cjarka_]

any particular reason why more often than not the CBN tools only have one CBN cutting tip?

[sicstar]

No Pat Benatar as soundtrack? I'm mildly sad. Sounds good tho on itself!

[DerEchteKorisander]

Warum sollte konventionell nicht genauso gut sein wie cnc. Mich würde mal Vorschub, schnitt tiefe, ausspann Länge und Drehzahl für beides interessieren...

[melendros-official]

lower the Vc by a bit and your good with those in the video lol. vibrations go away with higher F or lower Vc, if cooling/stability cant be enhanced. not every company buys expensive tools for hard turning. i used super cheap ones to expensive ones. sometimes cheap ones can do the job if you have single peaces to do

У нас в гараже когда что-то нужно обработать на станке - одно мучение, подача уходит, резцодержатель плавает и всё что обрабатывается то одним отрезным резцом.😢

[alexrovman]

Глубина резания меньше радиуса при вершине, то пластина работает как круглая. А у круглых пластин чистота обработки выше. Вот и весь секрет.

[АЛЕКСИГНАТ-тэ]

В чем смысл или польза этого видео? Напиши скорость и подачу - многим это будет на пользу… ну естественно вам поставят лайк..

[PaperMakersAdeludedbroad]

Whatever is cheaper will work fine. Affiliate links mean you're biased and can and will stage results.

[ianunderwood]

They both look like the same tips to me....
