The only thing I can get from google is that is a watchmakers drillpress. A few questions that I hope some of you can help me with. What is its application? (Is it simply...

    Grid drilling programming?

    Have you considered cam? Gibbscam have a utility that selects all the holes on a surface. If the holes are all the same distance you could use macroprogramming and save a few thousand lines of code. :D

    Measuring location of NPT thread on CMM

    I am not going to disagree with you on that! What really is silly is that the reference points is from a cast surface, and one of them is where they pour the metal so it has also been ground with a anglegrinder! This is not something that we want to do but the customer wants full CMM reports on...

    Measuring location of NPT thread on CMM

    Hi. We're having some trouble with the location of some NPT threads. Our CMM programmer have been scratching his head in a way that is leading to baldness! In his head he could find the center of a NPT thread the exact same way as a normal thread. (probing in a pitch) In my head that would lead...

    How to spin spindle in reverse in a mazatrol program.

    You should be able to input a gcode line, I don't know what the tab will be called on your control (since my control is in danish and mazak could not translate properly if their lives depended on it! It could be called 'manual' but that is just a loose guess!) When you input a fcode line, you...

    Kennametals KSEM tips

    Hi. We have some parts that require a 31.1mm hole, part is cylindrical so we make it on a lathe. Previous we made the part on some older Okuma lathes with plenty of power on the Z axis. Now, we have to do it on a new Doosan lathe, and it is week! Plenty of power on the spindle. but the Z axis...

    I have seen the levels things, and sure, if your lathe is 100% in level and you only use positive cutting tools I suppose that it is good enough...... But I see it as a waste of money and time.(just my thought about it, if others have the levels, use them and are happy! that is also fine! there...
