Remember the old SPI stubby, spiral flute reamers? Who makes those these days? I make a lot of 5/8 holes and think one of those would work great, just don't know who makes them.

Turning 416 with PVD inserts coolant or dry?
Turning 416 with Kennemetal 5025 grade PVD coated inserts 500 SFM .010 IPR .100" DOC (any more depth and starts pushing the bar back) and getting 45 minutes of cut time running flood coolant. With this type of coating should it be run dry?
Its rare we run anything other then 6061 and we alway run coolant.

Input and Output programs from machine
Hello all,
Here is my sad story :)
We have now 2 gildemeister Sprint65 machine which i can not move programs in and out.
It is Fanuc 310i control( i hate fanuc btw)
Need to be done via USB
I can see usb when i connect it . On the control it is 4 and selected under Memory card
When i punch program all i get on usb is program name and inside 2 lines
%
%
Most likely it is something stupid...but what
I tried getting help from DMG ...not working so far
I was able to punch all parameters from machine, macros...everything except programs.
Programs are inside individual folders , every folder have 4 individual programs, for 4 channels..
I tried to punch them 1-9999
All i got is al.text empty file on usb..
Did somebody run into similar issue and what is solution.
Quite frankly i hate fanuc and i am jot really wizard with it..
So, if somebody want to help , help me please like i am 1st grade :)
Thanks in advance

G42 with Fanuc 10T troubles
I'm having problems using G42 on my Hardinge CHNCII with Fanuc 10T. With G42 in effect, some of the position moves go opposite the direction they should.
This is the first time I've tried on this machine and my straight G-coding skills are a bit rusty. I've closely followed the Hardinge manual, checked all the offset settings, tool nose orientation RH #3. I wrote the code using NCPlot editor and the backplot looks good. When I run it without the G42 it functions as expected.
Here it is, in () is what is actually happening:
G1 G99 are in effect
X.2 Z.1
G42 X0.0 Z.006 (goes to position)
G3 X.192 Z-.090 R.100 (performs radius)
G1 Z-.1 (moves .010 the wrong direction, though absolute position shows it at -.1)
X.260 (goes to position)
Z-1.065 (goes to position)
X.360 (goes to position)
X.380 Z-1.075 (moves opposite to what looks like X.340 Z-1.055, though absolute position shows it at X.380 Z-1.075)
Can anyone see where my error is or possible cause for the moves in the wrong direction.

Alarm 1007 D400 SET ERR. ISSUE Hardinge VMC 600II Fanuc 0-MD
The machine was stored for a long time and lost the memory (exhausted backup batteries). We have loaded most of the parameters but the machine still with alarm 1007 D400 SET ERR., after some investigation (we don´t have the manuals) we found this alarm is related with the ATC Magazine so diagnostic parameter D400 should be set to 20 (now is 0000), the issue is that when we tried to input the value it doesn´t change even with PWE=1, Parameter 10 bit 4 = 1, MDI or EDIT attempted...
We need support to know how modify this value. Thanks.

Manuals Wanted Hardinge VMC 600II Fanuc 0-MD Year 2000
Hi, we bought a Hardinge VMC 600II 0-MD Year 2000, the machine was stored a long time and lost memory so, it was necessary to reset it, the issue is we didn´t receive any manuals, we have got most of Fanuc related manuals but still need to get the tool builder (Hardinge) manuals to know how solve some problems in order to bring alive the machine again.
We ask somebody help us to get a copy of them (operation, parts list, programming, maintenance, wiring, etc). Thanks in advance for your support.

Why hasn't this 2010 Brother drill tap sold ? Price seems ok...
Is it because one tool holder is broke, it looks like crap inside, and there are no hours stated ? Also it's obvious they aren't paying attention since they list it as a 21 tool changer. OTOH, unless whoever bought the 5 axis attachment started removing things besides the attachment (unlikely but possible I suppose), they are selling themselves short as it's actually 5 axis ready, not 4.
Still, if this was a 2010 Robodrill w/14 tool turret, 10K spindle at $35K or best offer I suspect it would sell quick. Thoughts ?

Replacing coolant hoses, with same clear pvc or something else?
I'm looking at replacing a few, or maybe all the coolant lines on my VMC while I clean and change it over to the 690XT. Had one crack on top for the spindle before and I just cut a few inches and stuck in back on(ok since), and the 1" ID spring hose from the pump to the manifold is also looking on its way out, a few have gotten pretty hard. Do you guys just use the same braided clear stuff, which is easy/cheap at any hardware store. Or something else better(yet easy enough to find), but what?
thanks

Air valve on Leadwell MCH400, need identification
There is an air valve on our horizontal, for the tool changer knockout cylinder (opens/closes the drawbar)
I don't know what to call this type of valve. It has internal valves, that I tried to replace o-rings in to no avail.
It seems to let air escape from one side when the other is activated??? I had it apart months ago, and had it "figured out", but looking at it now, I'm still scratching my head as to how it works, and why it is there.
The machine manual doesn't show it. I'm unsure if it was added later, but it looks like it wasn't. I haven't called leadwell (yet), I figured I'd give you guys a shot first.
Oh yeah, and it swivels around, allowing for rotational movement

Fanuc 1st adventure - robodrill
I took the leap and bought this from Milacron:
http://www.practicalmachinist.com/vb...oolant-324740/
Looks like a VERY nice machine. Placed it last evening, startup hopefully today.
Only had Haas(and Anilam GXM) before, never ever Fanuc. I'm preparing myself to adapt - but what advice do you have? From reading post history about Fanuc vs Haas, it sounds like I need to learn RPN Fanuc style......... Best way to start? Heinz Putz videos/dvds?
(Milacron presented the machine as it is, and was great at communication. Highly recommended)
Most of my work is 6061/7075 that I want to put on this machine.
TIA for any advice!

Drilling into solid PVC plastic
I am trying to drill a .750" hole into a solid PVC rod on a lathe. Total part length is just under 4" so I'm going at this from 2 sides. I can't seem to keep the plastic from melting. I've tried multiple feed and speed variations, coolant, and pecking and each run gives the same result. Every hole looks just as bad as the one before. Any advice or tips would be greatly appreciated.

5axis and 2axis laser tips ?
Hi everybody
So I wanted to ask if anyone had tips for 2 and or 5 axis laser. I've recently been asked to learn and take over the laser department at the company where I work. Im starting from scratch on the laser but I'm a licensed tool and die maker and run the wire EDM department at the company. So very competent and pretty familiar with nc code and setting adjustment, offsets all that stuff. We are running a komatsu 3000watt 5 axis laser and cutting a very large range of steels as they are mostly parts that come off the dies.
What I'm currently struggling with is getting clean burh free cuts with the laser, programming and running the machine has been a breeze. so if anyone has a foolproof method for setting a cutting condition in an unknown material please share. Also any Power Speed Frequency Duty and Pressure charts in relation to material thickness would be amazing. They would give me a good starting point, I've scoured the internet but its all cluttered with <100watt engravers.
I have software people coming next week and komatsu people soon after that to teach me some stuff but the more I know the more I can learn when they get here.

Doosan 2600sy part transfer question
Hello,
To start I want to thank everybody on this forum, I do not post often but I do browse these forums all the time. I have found lots of interesting topics over the years.
Currently I am working on a Doosan 2600SY. So far I am loving this machine as it is the first time I have worked with a sub spindle. Right now all of my part transfers have been done with both chucks stopped. I would like to try a transfer with both chucks synchronized together but i am not sure exactly how to go about it. The goal is to save cycle time. I have read through the books but I was hoping somebody might be willing to send me a bit of g-code that they are running with a synchronized transfer so I can see if what I have planned is similar to what they are running.
As a side question how much time does it save to do a transfer with the chucks spinning as opposed to stopped. I honestly can't see it being very much different. Is there another benifit to doing this?
Thanks

A new software for maho machines
Hi PM!
I was wondering if a program that makes it possible to use the so called "dialog" programming, for maho milling machines would be a hit? I'm a danish machinist, and I've been using this machine for about 2 years.
Please email me, or respond to this post, the software will be done soon and i want to know what people think :confused:

Looking to replace 3/4 niagara reduced shank with an inserted end mill
My boss wants to research into replacing our 3/4 Niagara end mills. They have a reduced shank for a 3 inch reach with 1 inch doc. These bad boys are 240 bucks a pop, and he wants to reduce cost. We cut a bit of 1018,4140 prehard, and fx (which has about a 40 rc). We use volumill a lot on the 1018 and 4140 pre(taking full depth cuts). The fx we mainly do side cutting, and sometimes flat lands.
Do any of you guys have suggestions on inserted, or any other type of tool.

Best turning tool clamping style
Was looking through the tool crib for something else and noticed we need to order some new turning tool holder and recall someone mentioning in another thread (can't find it now) about a new style of clamping system besides the tried and true pin and clamp style.
The kennametal catalog is a few years old so nothing new there so just wondering what you guys are using or stick with the pin and clamp?

How does radial chip thinning affect tool torque/cutting forces?
I am new to the concept of radial chip thinning. I understand the science behind why chip thinning occurs and how heavier feed rates can compensate for it. What I am not so clear on is how, if at all, does increasing feed to compensate for chip thinning affect the cutting forces?
For example, I am looking at feeds and speeds for a profiling operation.
Material - 17-4 Stainless, H1100 condition (HRC 31-40)
Tool - .750 carbide endmill, AlCrN, 8 flute
Cutting conditions - .0475 WOC, 1.3125 DOC
Manufacturer recommends 315-350 SFM and .0062-.0081 IPT for this cut/material.
Using 332 SFM and .0065 IPT with standard calculations, I come up with 1691 RPM, 87.9 IPM. If I account for radial chip thinning at .0475 WOC (6.3% engagement), I come up with an adjusted chipload of .01334 IPT, and an increased feedrate of 180.51 IPM.
First of all, am I doing these calculations correctly? I probably tend to run things on the slow and safe side, so at first glance this looks like a really aggressive cut to me.
Second, how do the cutting forces in the second calculation compare to those of the first? Do they remain fairly the same because the true chipload is still .0065? Or do they vary significantly?
Like I said, I would like to wrap my head around the idea of chip thinning a bit more, so all input is appreciated.
Thanks!
