PTGJ5750A RAM TYPE UNIVERSAL MILLING MACHINE:

Application:

This machine is a newly developed product based on traditional knee type milling machine and has more advanced features than the general ones.

This machine can mill any angle surface through front half-sphere by swiveling milling head.

Enlarged machining capacity, widened spindle speed range. feed of three directions adopt three separate infinitely speed changing systems which do not interference each other and possess working reliability, easy maintenance, long life, easy operation, automatic lubrication system, sufficient rigidity and so on.

This machine can mill plane, groove, slant groove, even can mill plane and groove in cavity of some workpiece.

Being installed with various kinds of borers, it can bore different holes vertically, horizontally, left-horizontally or right-horizontally.

Equipped with special-purpose tooling, it can bore inclined hole with special angle. it is suitable for metal-working operation of all kinds of factories, especially for die and mould.

"S" in Model No. Means with DRO.
