What do you want to see ?????......

[Hardmill]

WOW, starting a new place of employment never felt

this weird. Im actually in charge of what im doing (LOL).

 

OK so heres what im after, What specifically do you want

to see in the area of high speed and hard machining ??

Types to tools ?? Materials ?? work holding ?? Holders ??

In the next few weeks I'll be gathering together

tooling and such to get ready to blow up some

cutters and shoot some video to gain as

much data as we can in these fields.

The first machine on the chopping block will be a small

5 axis Okuma mill, and we'll be wanting to really test

its limits along with being able to finally

try out all the new "X" features. (really havent had time)

We'll get each machine with prolly a couple months

commitment from Okuma.

 

Ive seen what the Sandvik high-feed mills can do

and look forward to trying out as many brands

as possible.

 

 

PEACE

I would say along those lines to start. Look at Mit's for thier high volicety cutters. Thne would like to see some 58/62 rc roughing and finishing of toolsteels. I also think looking toward the titatium area and doing some parts along this land will give the machine some creditabilty as well.

Yes hard milling is good and also stuff that shows the machines smooth surfacing capability's like the transitioning over different surfaces smooth and accurately. Alot of the demo's I see are on dish shaped objects where even ho-hum equipment does well. jmo

[T_MALENA]

Try Iscar & Mitsubishi feed mills. Hardmills from OSG & Ultratool. How about some finishing cuts with a long reach ballmill. (apx. 1/4 dia. x min. 2.5 proj.) Using the HiCut & okumas nurbs. Hardmilling with a shellmill, anyone try this?

 

Hardmill do you now provide tech support for all of Gosiger? Specifically Gosiger cleveland/solon.

[Steve Zirtzman]

Hardmill,

We would like to see a comparison of similar tools from different manufacturers machining hard steel.

[Chipmakr]

We have tried tools from Tesco, Fraisa, Hitachi, Mitsubishi, OSG, and others. I would like to see how all these tools stack up in more controlled tests. These were all solid carbide tools in 58Rc + tool steels

 

I would like to see info on the roughing and finishing of the 58-65Rc tool steels including M series steels from a solid hardened blank.

 

A good test of the machines accel/decel features and the form accuracy.

 

As well as what kind of work and tool holding you are using.

 

We have a 2" Mits inserted highfeed cutter that kicks butt. We also have solid carbide highfeed tools we use down to 1.5mm that have slashed our roughing times.

 

We have tried without great success to use Greenleaf ceramic inserted tools in our hardmilling, but I can not get good tool life. I would really love to able to unlock the potential these tools seem to have.

[beej]

I'd like to see a comparison between OSG, YG, Garr,and several other Carbide endmill and ballmill manufacturers in 50RC steel.

 

I also would like to see how different coolant brands affect cutter life and finish.

[heavychevy2155]

I would like to see some prices on the web site. Just like starting price with standard features. just on some of the enrty level stuff.

Mainly gonna be covering the west coast, there is

one guy in Michigan. Together we are starting up their

die/mold group. If you got any specific question I'd

be happy to help if I can.

HardMill,

 

Video tape this Inconel cut. Its awesome to watch!

...

 

Here's the recipe:

1) 1.25dia X 3flt Kennemetal Facemill (.25rad inserts)

2)Kennematal ceramic inserts: KIPR125RP43540

3)4584 RPM and 41.25 IPM.

4).100" axial cut

5)Full dia cut

6)Run dry!

 

Oh yes..

 

7)50 taper horizontal mill.

 

You'll see the prettiest color of orange-red chips spewing off the cutter. The work doesn't get hot and you get great cutter life.

 

 

HTH

The Keneametal rep was here yesterday, so if a machine

presents itself in the near future its do-able.

We got a 40taper 5 axis machine coming in the next couple weeks.

Hardmill,

 

I'd like to know what is the best combination (Tool/Feed/Speed) for roughing a flood welded forging die.

[Hardmill]

More specifics would help alot, knowing the makeup

of the weld and Die are important.

In the past ive had the best results with coated

carbide mills. Although there are some great insert

tooling available.

Email me if you need more specific help.

 

 

PEACE

Hardmill, Nothing specific yet,but…

I did work with Dale at gosiger in mich. with our new MA400. he seems to be very intune with mold making. When you talk with him, make sure you brag about how good Mastercam is!

LOL, I just got off the phone with him

Well rib him a little. I think he's anti Mastercam. I think he uses one of "those other cam systems"

This is the first choice:

MU400v

 

Not avail til mid to late July,

This one we can have on the floor next week.

Hello, this is my first post so bear with me:

I have tried ceramic inserts with little success as well. From what I have been told after asking around, it has a lot to do with ridgedness of the machine/cutter.

 

It seemed whenever we tried to use them, they shattered before I got any real wear out of them. This was in hardened (62Rc) tool steel as well.

 

On the other hand, I have seen what these inserts are supposedly capable of. But in every demonstration I have seen, the depth of cuts have been relatively shallow.

One of the most important is work-holding and

holders, any chatter at all will cause these tools to fail.

Thats a big mistake that alot of tool reps forget to

educate their customers about.

Sometimes they're just too eager to make a sale.

 

 

BTW, Welcome to the forum FeareFerretNC

The 4020 is a excellent machine. This has been the most reliable, trouble free okuma mill weve bought. (Aside from our newest additions). I really like the P100 control. never thought Id say that before.

 

Hardmill youve got mail.

[Guest CNC Apps Guy 1]

Ceramic is about 100x more sensitive to machine/workholding rigidity. You don;t cut the same way with ceramic as you do with say Carbide, HSS, etc... It's a whole different way of thinking and it takes some adjustment.
