Yes they do but that tells you nothing about dynamic performance. Many a CNC machine can slew back and forth and get excellent repeatability while doing nothing. More important is how the unit holds up while actually doing real work. Will the ways be stiff enough to maintain repeatbility and is there enough mass to provide for good surface finish?
A person can gain a certain sense about how well something is assembled and designed by looking at pictures. It is the next best thing to being there. This is certainly not a substitute for measured parameters but such parameters don't mean alot to me unless I'm there observing the measurements. That may be pretty course but I spent a few years working in a machine tool rebuild operation and have seen many a questionable measurement technique.
Now I'm not saying that the IH machine is the best thing since slice bread. What I'm saying is that I've seen the unit online and at NAMES and can see that it is a nicely done CNC conversion. Is it an optimal solution, nope but improvements have been discussed here and on IH's web site.
So until I can see the Tormach machine first hand or get a better impression from some photos I can't really support it. That may very well change if I start to hear alot of comments from people using the machine with extensive machine tool experience and good metrology methods. As it is now though I have little to go on with respect to the Tormach machine.
Thanks
