Vertical Machining Centers

Vertical machining center with next generation specs for speed, heavy-duty cutting, rigidity, and compactness

Photographs used in this brochure may show optional equipment.

Rapid traverse

Class fastest slideways

MA-V series, next generation high-quality and high-

performance machines from Okuma, provides faster

rapid traverse and heavier cutting. The Y-axis column

feed allows the operator to approach the workpiece

and the spindle for easy handling, as well as saving

your precious ­oor space.

Machining capacity

Approx. 1.7 times more than our previous model

Getting the best from human operators and advanced machine tools

Satisfaction from complete control of a machine tool

Okuma Control OSP-P300M

As a “machine & control” builder, Okuma makes further strides in machine tool manufacturing with

this superb control featuring "Easy Operation." Okuma took a close look at the way machinists

actually operate machine tools, to help them create smoother and more effective ways of producing

parts. Novice operators as well as professional machinists get complete control—and satisfaction.

Moreover, what you want to see and do conveniently come together in a “single-mode operation.”

First, select one of three operation screens. Then simply touch the screen or press a function key to

see and do your job.

Easy tool registrationWith spreadsheet simplicity —tool offsets, tilt, shape, life, etc—all the tool data required to cut a part can be registered here.Since the registered tool data is also used by Okuma auto programming (Advanced One-Touch IGF) and a collision check function (Collision Avoidance System), this screen will complete the entire registering process.

The touch sensor screen pops up from the tool registration screen. Tool compensation values are set while looking at a guidance message.
