A neutral rake insert might be a good compromise.

If your nitride is a typical 65 Rc, good luck with HSS. How many tapped holes need to be corrected?

Good idea. Just thread it a bit oversize, and chase it with a die.

There are a number of companies that make good quality, inexpensive stick tooling. I prefer those with a single top clamp. Some holders require 2 different size allen wrenches when indexing the insert.

It will be interesting to see how the demo goes. We are trying to get a machine open in late August for them to come on site and run on our "problem" part. They will be bringing the tooling. I am under the impression that the insert is unique.

I have been programming, operating , and setting up Mazaks for three decades. If you have any questions, please feel free to contact me. Just curious, where are you located? I have helped on site a couple of people who were new to Mazatrol.

We have several older Mazak lathes and run right hand tools on everything. No issues.

I would sure like to see what the code looks like for generating the hex.

Seems to me that if it is chatter that he is trying to defeat, why all the material hanging out? Clearance problems I cant see? If your not rigid, you got problems.

We thought about rolling these, but the wall on this tubing is much too thin.

The part we make that gives us headaches is 4.5 diameter d.o.m. tubing with 12 t.p.i. threads 10 inches long. Thats a lot of thread. The material makes the chips very stringy and impossible to control. Over the years we have had numerous reps from different tooling makers attempt to solve the...

This video shows the creation of the code using their software. It does give you a glimpse of the generated code.

Sandvik is getting pretty heavily involved in programming software. I think they just bought MasterCam. This is a module for their CoroPlus Tool Path software. We are hoping to get Sandvik to come out and demo it for us on one of our NLX's. I have no idea what the software costs.

We have a job that is made from drawn over mandrel tubing. We thread the o.d. and have always fought the chips. I found this cool little trick from Sandvik. Anyone familiar with it or anything similar?

We use Mobil DTE 24 in our QT 15s.

Have you looked through the list of manuals for download in the Mazak forum? I realize they are QT 10 stuff, but you may find something relevant.

Do you have no programming manual at all?

I vote for backlash. A simple test will prove ( or disprove ) that.

You might look at a used Mazak such as a Super Quick Turn. You can still get parts for them, and its not hard to find someone to repair boards. The conversational programming makes it super simple to program hexes and such using your C axis. We bought 3 between 1993 and 95 and they are still...

Live tools are rated by horsepower. Some of the weaker live tool spindles might not develop enough low rpm torque to push a bigger tap. You do not need a Y axis to drill on the O.D. of the part, but you cannot drill off center on the O.D.. Whether on not a machine can drill holes on the O.D...
