Gate / Bridgeport Interract / Project

[SteveH]

Hi,

I came across your posts while searching the internet for data on my own cnc mill. From the pictures on this site your mill looks identical to mine - I bought it off ebay in September 2015 from a chap in Staffordshire, he had a pair to sell. My research seems to point to it being a Topwell 4BVK from a Taiwanese company, not a Gate machine. I have a copy of the advertising brochure (attached) from Sterling Machinery who used to import and sell it as a bare machine. I have also emailed the parent company to see if they still have documents for it (still waiting...).

I used a spindle motor from an old Bridgeport Ineract and 12Nm stepper drive combo's from Leadshine to build mine up then designed my own electronic cnc controller and wrote my own software from scratch to run it, I've turned out a number of parts for friends on it. Seems quite a sturdy machine for a small knee mill, backlash is 20/23um on xy but I hope to tighten that up, steppers are strong enough to snap 3/4" end mills without slowing, removing the Z axis gib to clean it up was a swine !

I will post a few pictures of it soon.
