Wow. up to three now. congrats. Did you end up making a decision on a medical mill?

I went cheap... Brother 27k RPM with a Yukiwa 5axis table. Getting installed tomorrow. 
I've been hammering on Grob USA to build a G150 but Zee Germans dont zee listen

Something to compete with Mikron HSM400u size parts... 40k rpm hsk40 etc. I've kind of backed myself into a corner only wanting Siemens controls on higher end machines...

Find a machine tool company you trust for good support / service and just add aftermarket automation. In my case I went with Grob ( I have 3 of their machines now... Gen 0 G350 120 tools, Gen 1 G350 200 tools, Gen 2 G550 330 tools) all being fed by Erowa robots of different sizes and capabilities. 

16 machines  total

6 5 axis machines, 1 500mm horizontal and the rest 3 axis verticals. 70% new parts 30% repeat work

Two of us handle all of it and its a xxxx show lol. We have to do 90% of the setup as well besides very simple 3 axis parts.

Could really use a third guy if anyone is from the bay area ....

Powergrip holder is like $350 plus a $100+ collet. The system is still too expensive compared to Shrink

Get an endmill and a block of material

Run G68.2 Cycle to A0C0

Position the tool in the +Y Axis

Side cut the block moving in X

Jump up and position back to the start X position

Use G68.2 to rotate the part 90* around Z. (A0 C90)

Repeat cut in X

Repeat this process until your block is cut

Go back to A0C0 and pick up center line using X

Then G68.2 the machine to A-90C0 and pick up the Z height of the block.

This should help you test your machine and find your problems.

No way a hurco or robodrill is going to hold +/-.00015 z depth off a non flat surface over a period of time...

.020 dia tool running max RPM

Yes!  Some grinding company sells a little bench top unit with an ER32 fixture that is meant for cut offs. It was like $3500 and I sent it back the day I opened it. POS.

I was just searching for this before I logged into this forum to see what was going on. Big market because of the shrink fit issues. Idk why shrink fit / tool grinders aren't in sync on this....

If you are programming at G54 and you have XYZ all set to 1.0 and run a G43.4 your control should adjust your 5 axis simultaneous moves to the correct position based on active work offset

Varimills are junk since they switched to the sub par blanks and widia > kennemetal ownership

Back in 2008 they were the xxxx though.

I didnt think they were too outrageously priced? $115 for a 6mm and just under $200 for 12mm

I doubt any custom place will make them for close to that pricing in only 1-2 pcs

I have a 6mm,8mm,10mm, and 12mm sitting on my desk but like he said before...
Everything is always a rush and havent had time to test them yet.

We just did a job with those tools. Customer didn't like the over $300 per tool price tag and asked us to go back to ball endmills.

 

Wait for it we programmed it in.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Mastercam. :scooter: :scooter:

 

I know of several other CAM Software's that can program with those tools just like that very easily.

Why werent they happy with the results?

What was your ball em step down?

Barrel cutter step down?

Please share more

40xd in that size drill with 3000 rpm?

>.<

I run a production part with 1000 psi

Guhring Gundrill .058 2.250 deep no peck

Works great and I've gotten 1000 holes out of the same drill so far in 6061

Hence new CUBLEX machines have FANUC controls. :

Because Matsuura couldn't integrate the Siemens very well?

So, that 0.250 radius part on the facebook page was done with mcam then?

That was me

Cory any luck? That 840 on the matsuura is xxxx backwards to the 840d/828d in my shop >.<

Yeah. I"ve  made over 20k using this method... works great. Just make sure you get the right pilot diameter ground on the bottom.

I have a tool just like this... I wonder if I know what part you are making

Buy a 5/16 aircraft drill and have a grinding shop turn it into a step tool with a pilot and counterbore cutting on the bottom.

What is the tolerance on the hole and location?

I ended up getting some shrink fit adapters in the smaller sizes.

 

If anybody is looking for shrink fit holders, talk to your OSG rep. They are discontinuing their toolholder line.

 

The holders they have been selling are Haimers with an OSG logo on them.

 

I put a big dent in their remaining inventory of CAT40, CAT50 and HSKE40. Scored 180 toolholders and extensions. Averaged out to about $100 each. If you've ever bought any from OSG or Haimer, you know that's practically free.

Yup.... I bought like 50 holders as well a couple weeks ago from this discount list lol. Got to love it when the little guys can score when the big guys get into fights!

You must have been the one who stole my cat40 order! haha

Programming from COR.... COMPLETELY old school and COMPLETELY unnecessary. Program from part datums and use the fuction as it was intended

How is this old school and uncessary?

Let me give an example from my Grob.

Lets say I have a part with a big flange. Datum surfaces are under the flange.

I can program the machine off x0y0z0a0b0 for every job.

Then critical job comes up where you need to probe the datums. I cycle800 to a0b0, probe in Z on one wall set my Z offset. Retract Cycle800 to a0b90 probe in Z and set the X offset.

How does changing where my program comes off change this?

 

Pay all that money for a nice machine and Methods can't even help you out with a basic question. I'd be pissed. :

 

The FANUC is more powerful than you think. It's WAY more powerful than even your above average user thinks it is. It all comes down to training. Most machine tool dealers do a xxxx poor job of training their end users.

 

Anyway, you should not have to pay for your machine tool dealer's general lack of technical expertise so against my better judgement here you go;

Hope this helps.

This result... should update X and Z offset... and not XY. What does it do in reality?

but but but... you don't have to call it from the top.

Yes. Should always call it at 0,0 rotation because what happens if there is a fixture offset ?

That is what I was getting to...

I program everything off COR. So if I want to measure a bore at B-90 then the probe results for the hole being off in XY would not go into XY. They would either be Y or Z because in reality the part is off location at b0c0

Thanks for your help .

You said "You just cant probe with W-sec or TCP active" but I dont see where you turn it off?

Is it too early and I'm missing something clearly obvious?

And if I'm reading correctly your probe results under the second move should update the X and Z offset and it wont try and fill in the Y value in the work cordinate?

Oh and if it makes you feel any better I helped a local buddy of mine make the decision to buy a new MX330 with the 10 pallet

What a tease....

lol

Any suggestions?
I guess I'm just spoiled with the Siemens control being so much superior...

Probing at an angled position and having it update the offset in the correct way. Lots of production parts we do need to be probed from b-90 because there is no clearance from the top to touch datums. Think aerospace brackets.

I've been using Siemens 840d machine and 828 controls since I started doing 5th axis and I've always been able to probe results while under Cycle800.

I inquired about doing this on my new Yasda machine and the service rep didnt think it was possible. Is there a special way to do this or does renishaw not support this?
