small chinese cnc

[vcosystems]

Does anyone have any experience of the small chinese cnc routers that can be found on e-bay.

I have been looking at this one:
http: //cgi.ebay.com/CNC-2520-ROUTER-ENGRAVER-MACHINE-/230486780297?cmd=ViewItem&pt=LH_DefaultDomain_0&hash=item35aa152989

Does anyone know approximatly how long it would take to route out an 10x15cm (4"x6") area 1 cm deep in wood?

Your Link does not work.

To cut your 4x6"square would probably take about 10-15 minutes in MDF using several passes, or about 15-20 minutes in solid wood with 3 passes. There are a few variables involved such as speed of machine, bit size, depth of each pass.

Do not know about the EBAY machines, but why not buy factory direct from Taney at Jinan quick CNC Router Co? I have a K6100A ( 600mm x 1000mm ) machine. It is a little ripper!
