I think they have a great product, but are alot more expensive than Lloyd, who can put you at dam near the power levels Ai packages do.

There are no seat and guide machines capable of those kind of tolerances...
I would like to see what dial-bore guage they have that will measure guide clearances to the micron...
I would like to see how much something that would measure .000039" would cost!!! best i have seen is .0001, and those are not cheap by no means... which if you are a company i guess money is no problem...

Our CMM(Coordinate Measuring Machine) measures to .8 micron...and costs 50k + used. It's a line of BS, they can't measure to that accuracy.

Once again an internet “guru” takes center stage dispensing advice & opinions that are totally inaccurate and then insults us implying that we are lying.

We did not claim that all tolerances are held to a micron. We stated that we utilize the metric system and can measure to within microns (1 micron = .000039in). We use high end Mitutoyo & Fowler metric gauges. Our Mitutoyo (#526-124) Split Ball Bore gage can measure guide to stem clearance to less than a micron. It is graduated in microns and it is possible to easily read within ½ of a micron. It is possible to get guides straight within 1 micron using a Sunnen hand hone if you know what you are doing. Seat concentricity and true position can be held to 10 microns (.0004”) on the Newen Epoch or Contura CNC.

Not accurate, we are in the process of revamping our product line. Check out our new H/C packages starting at just $1,099. (Click on Products then LT1 on our site) Compare our work and proven performance on the track and street with the competition and we offer one of the best values in the market.

To our valued customers, thanks again for your support!

You would be hard pressed to find a CNC mill that can hold to the .00005" without chasing offsets around trying to compensate for air and coolant temperatures.

I'm just quoting what was on the site....that tolerances are held to the micron; that implies that you measure guides clearance and seat concentricity to the mentioned tolerance...because that is what you are selling. Saying that you have the ability to measure, and actually doing it to every single guide, and holding .000039" in clearance from top to bottom are two different things. Just because a guage is marked for .001mm does not mean it is accurate to that number, I believe most of those mitutoyo's are accurate to .00015". As I said, anybody who has worked CNC machines trying to hold that accuracy knows that you are constantly changing offsets to keep withen tolerance due to temperature variances and tool wear..... I don't measure heads for that kind of tolerance because there is no reason to...literally splitting hairs. If you actually do, I stand corrected.


Yes, my seat and guide machine can hold to the half thou no problem...
