Yea our main problem is the live tooling spindle on this machine is only 7.5HP and the torque is minimal at low rpms that is the main reason we went to the indexable because you can run the tool faster and get optimum torque. We do alot of these parts so we need to find a full proof way of doing them. This is the only mill/turn we have, we used to do them on a 50 taper mill with a haas indexer but the setup took some time. We tried bringing the tailstock in for added support and its hard to beleive but it made the chatter worse.

Ok, at first we came in with an endmill to just rough out the counterbore and then came in with a cemented carbide porting tool but it kept spiking our load meter. It took alot of time so we got an indexable porting tool in for test but im starting to think the first way is the route we are going to have to take. Thank you for the response

We are using a metcut #8 indexable porting tool on a mori nl-3000y mill/turn and we are having a hard time getting a good finish on the o-ring surface. We are running at 1500 rpm to start with a .004 chipload and once it reaches the o-ring suface we turn it down to 1000 rpm and then when it gets to the counter bore it is turned down to 390 rpm. It starts to chatter when it gets down to the full depth. We are not porting on a flat surface so we have to bring the tool down until the counterbore cleans up all the way. The material is a 6.0" piece of 1040 steel. Does anyone have any recommendations? Thanks for your time

Yea I loaded that file as X5, not thinking. I dont have X3 on this computer

Is this what you were thinking? SAMPLE MCX-5 FILE.MCX-5

Its no problem thanks for checking. I looked at just about every manufacture I could think of and didnt find one. We will just turn down the shank. Thanks again

Did you look in your post dialog defaults? Settings/configuration/post dialog defaults. I dont use MC to send to the machine but this might give you an idea.

Do you know what kind of sandvik drills you use? I am looking through the sandvik book and the 1.063" drill is a 1.25" shank. Thanks

Ok, yea its only 7.5 hp but were mainly just looking for drills that are in the range of 1-1/16 to around 1-3/8. Thanks for the heads up

We are getting a mori mill/turn in a week or so. We purchased ER40 collet tool holders for our live tooling. Unfortunatley we drill some holes that are over 1.0" in dia. and the collets only accept shank dia. no more than 1.0". So my question is do you guys know of any manufactures that make a good variety of indexable drills over 1.0" with a 1.0" shank or any other options we might have. Thanks

thats what it sounds like to me

To me it sounds like creating your original geometry in three seperate lines then translating or offseting each line where you want and using seperate tool paths is the only way to go. Maybe someone else will have a better way but thats all I can think of.

I dont know exactly what your trying to do but could you use 2 different toolpaths, 1 for the test cut (w/ your tool leaving material in x) and one for the finish?

What version of mastercam are you running? Are you running two seperate groove toolpaths for roughing and finishing?

If you have a presetter it will attach to your machine by the chuck and it has a stylus that you touch your tools off to so that you can set your tool geometry for each tool. It will set your tools in all axis. Whether or not you have to manually input the data or if it automatically inputs it into your geometry offset page all depends on the machine. Do you have access to mastercam?

What kind of machine are you dealing with? Do you have a manual or automatic presetter?

It depends on what your trying to do generally its off of centerline, when programming the toolpath the software will automatically compensate for the tool dia. If its something that needs to be dialed in to a certain dia. then you can add a dia. offset so the tool can be compensated for. Or if you use alot of reground endmills you can have a dia offset so the actual dia. of the endmill can be input in the machine. There is several routes you can go it just depends on what you are doing and tolerances and tooling. Another thing to add to the above comments is if you are programming a machine w/ "Y" axis and you are drilling holes off centerline you will need to draw an arc to chain instead of a point or else the tool will always drill towards centerline.

Are you talking about dia. offset or length offset or at the machine?

Being able to rotate the turret with the handle control definely seems like a useful tool we will use here. Thanks for the good info.

Just create folders on a flash drive for each machine you have and copy the wmd, lmd or mmd file the .control file and the .pst file into those folders. Load it on your new pc, create a new folder called files for update or whatever you want and update one machine at a time. I just did the update from X2 to X5 and thats what worked good for me.

I just tried duplicating the problem with no luck. Does the tool look normal when you select draw tool?

We purchased the 3000 series because we machine alot of long chrome rods. I believe it is the longest that Mori makes in that model. Do you have big issues with cross drill clearances between the shroud and turret when indexing. Thanks for the reply

At the top drop down menus go to solids, fillet, then solid fillet and that should give you what you want.

How do you like the operation of them. Is the controller pretty user friendly? We do alot of bigger parts and cut mainly steel.
