Special BIAX scraper

[mecanicadeprecisio]

I've just seen in this video from SIP (SIP the World of ultra high precision Jig boring machine) they are using what it seems to me some kind of special BIAX scraper.

Does anybody have any information on this machine?

That's an BL-10. I am the BIAX Scraper International Instructor. In my opinion they are using the wrong blade holder as that blade is very stiff. Experienced scrapers use them. Sip used to have 80 Biax Scrapers. Sip went out of business. They used to have a rebuilder in New York.
I still teach scraping in the USA. One of my students bought a BL-10 off eBay today. He got one just like that for a bargain $1800.00 .

The head is different with BL-10. It's like a Solid machined part. Some screws also added. Maybe the client modified it himself.

Hello Richard,

I already own a BL10 and I did a scraping course in Austria, and as Digitalmg said, the head looks like a machined part and has some screws on the side, it would be interesting to know why the machine was modified.

Also I can tell you for sure SIP is still building machines (and scraping) in Vuadens under the Starrag umbrella

Hi Bakafish ! I've been following the PM forum for a few years, and I can tell you (almost) for sure there's no Biax like the one in the picture in this forum.

I will write Biax in Germany and ask them. Or email me and and I will forward it to the head of sales.. [email protected]

Ahh, I misunderstood that you were pointing out the apparent modifications to this unit. My guess is these are likely repairs, as new Biax are expensive even for big manufacturers. If you dropped one and broke the forward bushing mount, one possible repair would be to machine a new nose extension and anchor it to the main housing with the bolts seen in the screen grab.

I sent this to BIAX and we will se what they say.

$1800 is a bargain ! I sold my trusty old flaker a few years ago for about $300. Sounds like somebody else got a bargain !

I heard back from BIAX, Here is what they said:

Everything ok, this was a special design for SIP, our Swiss guys say.
If you look closely you will see that the scraper tool holder has a double bearing (bearing in front and behind the tool holder).

This model had the designation BL-10F.
We only had a few built at the time. This machine was also relatively costly due to the design construction.

I got a quote for a 220 volt HM-10 on 4/10/23 from DAPRA / USA BIAX importer and the USA retail price is $5919.80. They said that the 220 V motor was only $200.00 more then the 110 volt model. A new HM-10 1/2 moon flaker retails for $6206.04. 220 volt.
The friend who bought the black motor HM-10 on eBay yesterday also got a blade kit with it that retails for U$D .716.33. Yes if you sold your 1/2 moon flaker for $300.00 your customer got the biggest Bargain ever.

It was the guy in Norway I think. Jan ? At least it went to a good home.

That was the older style that was blue. That unit was probably 40 or 50 years old. Have you watched any of his You Tube shows? He must have over 200. He rebuild several Myford lathes.

He's taken and helped arrange 4 or 5 of my classes. He took his first in Georgia USA had to have been 10 years ago and helped in 2 in Norway, 1 in Sweden, 1 Denmark. He and another student are originators of the Facebook Scandinavia machinist forum.

Yeah it was an old blue one. It was still going strong though. Still producing neat half moons once you got the hang of it. You could use it for roughing out also. It originally belonged to “ Asquith” who made the radial arm drills and huge floor borers. I got it in exchange for some work I did.

What would be the benefit of that special design ?

Knowing it is a factory variant and taking another look, those screws on the side appear to be some kind of gib adjustment. I don't really see the wear plates that the shoe rides on either. Wondering if they redesigned the method of keeping the shaft from rotating, the plates and shoe tight tolerance always seemed like a weak point of the design for really heavy production use.

I completely agree with Bakafish about that being the weak point of all Biax scrapers: they are prone to attract abrasive dust and their wearing sneaks up on you. Sometimes you tend to blame yourself on not being good at hitting the intended spot, ignoring the side-to-side rocking motion of the blade holder.

Thanks Richard ! That makes sense.

It's hard to tell from the videos either it has shoes or not, but yes it seems like a properly reinforced version

What other power tool product lasts 50 to 60 years? Our first power scraper back in 1972 cost $475.00 I thought that was expensive back then .and I suspect it is still running
Amortize that over 50 years.
