Boxford Lathes
Boxford Lathes draw on a wealth of manufacturing experience and incorporate
many features normally found on more expensive machines.
Designed on functional and ergonomic lines they incorporate simple but
sound engineering principles based on volume production methods.
Robust and reliable, they are ideally suited to toolroom, general engineering
workshop requirements and vocational training programmes. They are manufactured
to IS0 standards throughout.
