Double Column Machining Centers

1 2

In 1964 Okuma introduced the first double-column machining

center. In the almost 50 years since then, we have shipped

over 8,000 units into a wide range of industrial markets. We

have earned the trust of manufacturers and built a solid

reputation of quality, reliability and service.

Okuma’s “total responsibility approach” combines electrical,

mechanical and control technology, high product quality,

machining know-how and ease-of-use. This provides high-

rigidity, high accuracy and a product line that our customers

can count on.

Okuma stays ahead of other machine tool manufacturers with

a consistent approach to the art of manufacturing, employing

“Only One” technologies to produce a full line of double-

column machining centers for nearly any large part

application.

The elevating crossrail has sufficient length and a structure for accuracy and long life with no "snaking" movement.

Double-column construction with square columns maintains good rigidity with respect to vertical loads, horizontal loads, and torsion for heavy-duty cutting with high accuracy.

Crossrail clamp

Elevating crossrail guideway

Powerful clamping device in which the lever principle is applied to the crossrail clamp.

The spindlehead guide has a wide, highly rigid rectangular cross section, and is supported by a deadweight balancer via rollers on the crossrail. This gives high speed, high accuracy movements and high quality machined surfaces.

The weight of the table and workpiece is supported with roller bearings on hardened and ground surfaces. Movement is not affected by weight changes from heavy workpiece loads, enabling light, smooth movements and accurate positioning. Layout includes the drive system (ball screw) in the table center with a narrow width between the center guides, to achieve outstanding linear motion straightness and long-term stability.

■B-/C-axis universal index head

■90º angular head

Full array of headsAll types of cutting in all types of shapes can be machined by changing the wide array of heads.

Many different processes can be performed in auto operation with the auto tool changer (ATC) and auto head changer (AAC).

Automation for highly productive and flexible performance

Smaller and faster AAC

Completely automate machining of multiple sides with a variety of heads that mount automatically and accept ATC.

Fast NC-ATC

One arm performs the changes for both the horizontal and vertical spindles. The next tool to be used, regardless of the spindle location, is brought to the standby position during cutting. This simultaneous operation greatly reduces tool-to-tool time. ATC is available for 30°angular

heads and universal index heads (B/C axis) in addition to extension heads and 90° angular heads.

From theory to effective machine applicationsOkuma’s Intelligent Technology

● Integrated machine design and control technologyThe Thermo-Friendly Concept plays a principal role in our machine design. With simple machine designs and construction that equalize ambient temperatures, deformation is predictable, and complex torsion or tilting is controlled. Moreover, highly accurate compensation technology (Okuma control [OSP] award winning innovation) effectively responds to deformation caused by changes in room temperature, frequent spindle speed changes, and non-coolant cutting.With the Thermo-Friendly Concept (Manageable Deformation—Accurately Controlled), Okuma products provide unrivaled dimensional stability.

Thermo-Friendly Concept

• Thermo Active Stabilizer––Spindle (TAS-S)Thermal deformation from spindle rotation controlled with high accuracy.

• Thermo Active Stabilizer––Table (TAS-T)Control of deformation from thermal expansion of table.


• Thermo Active Stabilizer––Spindle (TAS-S) • Thermo Active Stabilizer––Construction for large

machines (TAS-C2)

The machine is optimally controlled to maintainmachining accuracies even when ambient temperatures change.

Environmental economic benefits ofOkuma’s Thermo-Friendly Concept

In environments with normal temperature changes, machining accuracies equivalent to those in temperature-controlled rooms are achieved. As long as the operator is comfortable, there is no need for air conditioning to ensure accuracy.

■Amount of energy consumed for temperature-controlled room

Savings of approximately 43,400 kWh(*1)

Prevents CO2 emissions equivalent to about 24,300 beech trees per year

●Allowing operators to focus on making partsNC controller (OSP) with 3D model data of machine components –– workpiece, tool, fixture, head –– performs real time simulation just ahead of actual machine movements. It checks for interference or collisions, and stops the machine movement immediately before collision. Machinists (novice or pro) will benefit from reduced setup and trial cycle times, and the confidence to focus on making parts.

Collision Avoidance System

●Maximizing machine tool performanceBased on the chatter noise captured by the microphone, Machining Navi displays a number of optimal spindle speed possibilities on the screen. The operator can change to the indicated spindle speed with a single touch and immediately confirm the result.

Satisfaction from complete control of a machine tool

■Setup operations

■Trial/continuous cuts■Programming ■Tool preparations

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.

With 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.

PFC Projection Flat Control

Lost motion and backlash from axis reverse movements occur at various speed levels.PCF II dynamically flattens out spikes when circular quadrants switch.

Feed axis bending compensation

Bending is caused by expansion/contraction and torsion of the drive system. Unevenness from reciprocating movement can be minimized by compensating for bending produced during acceleration and deceleration. This is particularly effective in die/mold machining.
