Part off tools: What's working for you?

aj · Jul 13, 2020

Good morning gents.

We've been running Manchester/Widia part off tools for over a decade with great results but we've been told they're being discontinued.

I wanted to ask the group if you have something you're fond of. Our big 'stickler' is a job we're running right now: 2 1/4" 303 stainless. Our salesman brought us a Seco part off tool but the thing screams like it's being tortured and we only get around 80 parts per cutting edge before it fails and takes the holder with it. The Seco rep even came in to try and help, but just made things worse.

So if you have something you're happy with and you're willing to share, I'd like to hear from you.

Thanks guys.

Ditto

Since we switched many years ago our blade holder consumption is way down, insert use is down and we part off constantly to the tune of thousands of parts per week, every week of every month of every year.

Good product

Another vote for Iscar, all my parting tools even down to the ones I put in my small Swiss machine are made by Iscar. They are on the expensive end, but worth every penny.

We are running a promo on the new Iscar Tang F Grip blade and adapters. Buy 20 inserts get free blade which they call the adapter. Buy 20 inserts get free block. Same deal on the Do F Grip. PM me if interested.

Walter have the best cutoffs I have ever used

Manchester was the ultimate cutoff but Kennmetal killed that line

Our Kennametal Distributor had us try the their "Beyond Evolution" cut-off line. When the holder is plumbed, it gets the coolant right to the insert. I went from an average of 300 parts with the widia to 3000 parts before significant wear with the beyond in 303 Stainless with a 1.25" diameter. It worked really well. I cut the count down to 2000 to be on the safe side.

1.25 diameter 303 and 3000 part off....this I'd like to see. I don't know of anyone getting 3000 part offs in any steel let alone stainless.

I don't know... those holders with thru coolant to the insert are a big deal for tool life IMO.

Does this only work with high pressure coolant?

No, but the more pressure, the better.

Two big benefits to the coolant-thru part-off blades. For cutting edge cooling, the under-side jet provides the biggest benefit. The lower jet (spraying upwards toward the cutting zone) actually does more to cool the cutting zone than the other jets.

The upper jet, does more for leveraging the chip away from the insert, leading to better chip evacuation, and therefore less heat-soaking near the cutting zone.

FWIW, we use Iscar's Tang-Grip in 303 with a J chipbreaker and IC908 coating. It has a shrill shriek as it cuts but we're running .008 IPR............

Works great.

I'm a little curious why the Seco didnt' work as well. Makes me think that maybe...

1- the toolholder wasn't straight to the X-axis. (Might not be the case if your previous tools ran OK, and didn't show any signs of the side of the blade wearing prematurely, or a wandering cut...)

2- Maybe the wrong chip-breaker? Their 150.10 inserts have a few chip-breakers - perhaps they selected too "tough" of an insert, maybe not enough feed, or built-up-edge perhaps, being stainless?

Either way, the Iscar part-off tools work great. If the Seco folk can't figure out how to make it work well, you won't really find a "better" part-off tool than the Iscar.

Coming from a former Seco salesman, that means a lot..........

On the other side of the coin, Iscar finishing inserts get kicked by Seco.

What width do you use?

These were discontinued about 7 or 8 years ago I think. Kennametal couldn't supply me, I bought from carbide depot until they were cleaned out. Since then I've been getting inserts off ebay.

I just cleaned out a seller for more than 100 inserts at a little over $5 ea. I use .094, but he has a bunch of sizes left that I don't use.

I like these too, I had assumed I was going to have to switch to something else until another member alerted me to the ebay guy...

The Seco wasn't even close. We're getting 800+ parts per edge with the Manchester and we're struggling to get to 100 with the Seco. Don't know if it makes that much difference but the Manchester is 0.125 wide and the Seco is 0.160. It doesn't seem like that much, but I did a little quick math on one of our long running jobs (138,000 pieces) and the difference between part-off width is going to cost us 33 more bars next time we run it.

The Seco rep is supposed to be here Monday with "the fix", so we'll see.

Has anyone tried the Y-Axis parting from Sandvik?
Looks pretty good.
I'm thinking about giving it a try.

That's what we're using.

Very reliable and the blades are double sided, in case you F up one side.

We previously used Iscar Penta IQ Grips but switched to Tang-Grip due to the OD limitation of the Penta.

How the heck to get out of bed knowing you have a job with 138,000 pieces? :eek:

Yuck!

Easy. Hearing the part fall in the chip-catcher = money clanging into the coffers.
