The Okuma VTM-120Y-b 3+2 axis combination lathe/machining center can perform turning, vertical, horizontal, and angled surface machining in one operation without reorienting the part in the chuck. With operator control of spindle direction in relation to the surface of the work-piece, side cutting with straight end mills can be used to dramatically reduce cutting time compared with point cutting using ball end mills. The work spindle is supported at two locations by large diameter roller bearings offering precision control for the production of complex parts. The spindle’s geared head generates high torque capable of sustaining the heavy cutting necessary for parts such as large valve bodies.

 

The Okuma 120Y-b is the largest machine of its type in the Inland Northwest of Washington, Idaho, and Montana. The Okuma has a 48" chuck for vertical lathe operations, can cut up to 49" OD and has 59" of swing. This machine can do lathe and mill operations in the same program, and is able to work on steel, aluminum, titanium, and any other material. Please contact us to come by for a visit and see it in operation or send us prints to look at for quoting.
