Help Understanding Grizzly Mini Mill Specs

All,

I am not familiar with the machining terminology and am having
trouble interpreting the specs on the Grizzly site for the Mini Mill.

The site claims this mill can do "up to 1/2" drilling, 1/2" end mills
and 1" facing" does this mean only have Z travel of 1/2" and X,Y
travel of about an Inch.

Could someone explain whats the maximum X,Y,Z heights I can machine
on a grizzly mini mill.

Thanks for your help and hope you excuse my lack of knowledge.

Thanks
Jay
