I learned long ago that most of the time reps will try and sell you more than what you really need. I have had several different tool reps in here trying to tell me that the only insert that will...

I had an iscar rep out here yesterday. He is sending some inserts for us to try that another shop has had success with. The grade is a IC907 which is for hard part turning it should be here soon...

The process you described is exactly how we are doing it. I am not sure how the heat treat company is doing the case hardining but my experince tells me its heat treated all the way through. Thats...

The problem with that is that the part is so thin that the case hardening creates to much warp on the part.

Do they make tool post grinders for cnc? I have used them on a manual but haven't ever seen it on cnc.

The OD is 6.745 the ID is 6.045 and it is .352 thick. It has a 46.55 degree angle on the surface were the rollers will sit. I have tried a Sandvik PCD insert ( I can't give more info because the...

I am currently trying to machine some bearing races that have been case hardened to R60 .06 deep. I haven't found anything tooling wise that will machine the part after heat treat that will last...

got to http://www.cncci.com they have great programming books. That is how I learned

I recently brought this problem to my iscar reps and they said for this type of aluminum when you need a good surface finish a PCD insert is the way to go. They are high dollar though.

Thats what I thought. The good news is I don't have to continue to debate this issue since I only have 3 days left with this company

I agree with the speed try slowing it down. I have a part that is 6061 Heat treated and its harder to machine than my 4140 tool steel. "Slow your RPM down your running to fast."

convert all you measurments to mm by hand, and then put G21 in your code and remove any G20's.


G20= Inch mode
G21=Metric mode

Utilization is how long the machine is in a cycle. If your shift is 8 hours and your machine is
in cycle(making parts) for 4 hours than you only have 50% utilization. In theory your machine could...

I will be posting alot of questions. I got the job today and start on 7-1.

I never found the exact manuals for my controls I recieved some that were close but not exact.

Tommorrows the interview. Now that I know that the machines are mazaks i'm nervous.

I use Iscar. The reps can cut you good deals if you work it right.

I understand the part about checking the head first and how to check the head. You confused me on the tool turret.

Me personally I would use a groove tool to rough it out then make a finish pass with a turn tool. Not real sure that I would use a canned cycle at all.

I had an operator crash the tool turrent into the spindle while running. I believe it knocked my turret out of alignment because nothing is cutting on the correct edge of the insert. I got...

I don't know about SQL but I have asked my reseller if there was a way to setup directory structure so that depending on what post you use is where your files save. Also asked if there was a way to...

95% of what I machine is castings I have never used G73. I use G71 and G70 all the time.

Thanks for all the responses. Looks like it won't be too bad afterall.

I can do more than click post. I hand wrote everything for 2 years. now I cam unless writing a macro b program. I just don't know if the fact that I haven't done mazatrol programming if that will...

I ask because I have a job interview for a programmer position. I have only used g code on fanuc, fadal, and haas. They said that there machines had mitsubishi controls using mazatrol programming. ...

I didn't look that closely. I saw the positive z moves and took that as the first problem. Your right. Is this a proven program?

I have never used a Mazak control before. I heard they are great for conversational program(which I have never done). Can they be programed for conventional G and M code also?

Since you Z depths are a positive number and there at 17.3519 I would assume that the program zero for z is below the surface in which your drilling. eg. All the tools have been touch off the...

Routinely yes that is correct. I work with 95% castings we have several parts that require a certian amount of the orginal cast to be removed its easier and quicker to part the uneeded part off then...

Does fanuc have a electronic version of there operator manuals. I have hard copys would be nice to have in a pdf format though?
