On The Wire -ARC Cutter Review

Two videos and some larger photos to go with the review of the ARC Euro Trade indexable endmills and shell mills in MEW 289. Video best viewed direct on You-tube so the captions can be read more easily.

The cutters being used on Sieg X3 & SX2.7  Mostly the 63 & 80mm shell mills on a mix of cast iron, steel and aluminium.

Two larger photos of the finish on some unknown steel cut with the 80mm Shellmill on the SX2.7, click any image to enlarge further.

Assortment of materials cut, from L to R - Cast Iron 6082 Aluminium EN3 and unknown steel with the CNC machined 6082 part in the foreground.

Just bumping this one up to the top now that I am informed that the paper mags have landed, I think whoever makes the digital one available must be on Holiday.

Nice demo! They look like really good quality tools, as is most stuff from Arc.

I have a small 50mm dia indexable face mill, but rarely use it, mainly because I end up with the workshop full of little razor sharp swarf everywhere! I need to get myself a fully enclosed mill.

What spindle speed Jason? Is it likely to give the same results on a non cnc machine? Thanks.

Cutting speeds are in all the captions and only the last fancy shape was on the CNC so rest done on machines with a max of 2000rpm, again machines used in captions. Cuts on the SX2.7 also show th espindle speed display

Depending on diameter the face mills were run at 600-800rpm on steel and cast iron and 1750-2000rpm on Aluminium and smaller 25mm dia one at 1750-2000rpm on steel and iron on tmanuals and 5000rpm on te hCNCto give the cutting speeds shown.

Why does someone invent tooling that goes in steps giving 40mm, 50mm, 63mm, 80mm diameters? Would it have been so bad to go for 65mm?

Possibly a close approximation to the old 2 1/2 inch ?

Hopefully we will see the digital MEW289 today.

I've had no problem viewing the digital copy of 289 on this forum and Pocketsmags on my iPad since last Saturday.

P.S.  The paper copy came on Monday!

Jason, what is the weight of the 80mm with inserts please ?

Emgee

That's odd John, although 289 shows on teh home page and at the top of all pages when I go to Magazines and select MEW they only start at 288?

Emgee, I will get back to you shortly.

I bought one of the 25mm end mills, been using it on black mild steel and it works very well, good finish. The inserts seem to last quite well also.

80mm Head with the torx screws is just about bang on 1000g and another 70g for six inserts

No I am only seeing 288 as the latest in Magazines..?

Ron/Jason,

You are both right, of course. Only on Pocketmags from Saturday. It normally appears on here the same day for me, at least, so I got confused. Easily done, these days, I'm afraid.  I'd blame it on too much mulled wine, but I'm only allowed one pint of Guinness a week due to medication! To paraphrase the old saying - "Read twice, post once!"

Happy New Year.

Spelling corrected.

Jason, thanks for the weight, so 1070g is that inc the arbor or not ?

Reason i'm asking is that's very close to being too heavy for my machine, especially at 2k rpm.

Emgee

XD351 wrote Possibly a close approximation to the old 2 1/2 inch ?

It's possibly a close approximation to the current 2 1/2 inch as well

Roy

Emgee, without arbor. What do you have I can weigh MT3 & R8

Thanks Jason but I can add the weight of a BT30 arbor.
Nice surface finish on all those pieces, good demo's.

Emgee

I just tried ordering some indexible bodies and arbors from Arc. Both R8 and ISO40 arbors are out of stock, with no restock date. Seems pointless to review items that one can't buy.
