I should have paid more attention to online reviews of this Table that is manufactured in China. If you already have a Milling machine, then getting this product ready for use wouldn't be as much trouble. It is not a very well machined tool, even for a $150 product. The T-slots on my product were inconsistently cut (on both slots and even end-to-end within a slot). My Table (as others have reported) will not accept the recommended 5/8" T-slot Nuts. The slots are milled too narrow, so maybe save yourself some headaches and milling work and purchase the 9/16" T-slot Set. There is no way that someone at the manufacturing plant ever slid a 5/8" T-slot Nut into either of the T-slot channels on my Table. That is unacceptable to me and should be a basic check that should be done.
The Leadscrew Support Blocks (on the lateral axis) are cut too wide and actually overlap the inside edges of the T-slots. So the Support Blocks on my Table also would need to be milled flush to allow any T-slot nut to be inserted.
The entire table is very loaded with oil and grit, so plan on dismantling the entire thing to give it a proper cleaning before use. If you are looking for a table with smooth Ways, this Table was not milled to that level of quality. The Ways are semi-smooth to rough and again there is no consistency in the machining from one end of a Way to the other.
If I were Grizzly, I'd drive much better quality from the plant in China. If they really do use ISO 9001 practices, it is time to enforce it with the lack of quality on these Tables. From my perspective, the hours that I have spent and will spend to get this Table into operation far exceed anything that would be considered "reasonable". I would have been willing to pay more for this product to get better quality that what is currently being offered.
I do give very positive words to Grizzly Support for their understanding and positive attitude when I called them to report these issues. They do admit that at this price-point, you can expect to see what I've seen with my Table. So, I'd say only buy it if you are willing to accept all the corrective work that will likely accompany the purchase.
I hope that Grizzly will post this review because what I'm sharing is true of my purchase and not at all inflated. If you take the time to read reviews of this product online (Amazon and other places), you will see very similar comments.
