Highly rigid and accurate machine construction
Big parts machining expertise. This machine was engineered with Okuma’s
field-proven experience of building in exceptional power, rigidity, and smooth
operation to assure close tolerances over time and high production. The
shudder free design means heavy-duty face milling and flawless fine
boring—superb for fast and highly accurate machining of dies and molds.
Parts that had to be cut on several machines can be finished on one MCV-AII
for dramatic savings in prep times for each process. And the ATC, and APC
for continuous operations provide even greater productivity.

Stability and high-accuracyfrom the spindlehead ways
� Direct-drive gearless spindleQuiet, vibration free operation
� Ultra-precise spindle bearingsDouble-row cylindrical bearings and special angular thrust bearings for 3-point support to assure consistently high accuracies and rigidity.
� Spindle cooling system standardPrevents thermal deviation of spindle
Positioning is fast and smooth with the roller-mounted weight balancing system.The sliding surface absorbs cutting vibration, leading to high quality cut surfaces.

Rock-solid double-column construction: Key to closer tolerances and greater rigidity
Heavy cutting of big parts at extremely high accuracies comes 'natural' to the set of stiff, square columns straddling the solid bed which supports the table. Virtually chatter-free rigidity under vertical, horizontal or torsional loads. Result: Okuma high accuracy.
Long crossrail guideways ensurehigh accuracy and long life
The extra long upper and lower vertical guideways on the crossrail present a stable structure that ensures longer service life and rigidity. The wide spindlehead guides are highly rigid rectangular sliding faces.
Slide/roller guideways
The table uses a combined roller pack and slideway system to absorb a high level of cutting vibrations. The roller bearings on the ways support the table and workpiece to enable smooth movement and high-accuracy positioning and maintain high accuracy over long periods.
Powerful clamping
Powerful clamping devices that apply the principle of levers are used on crossrail clamps for powerful machining.

Satisfaction from complete control of a machine tool
Okuma Control OSP-P300M
�Setup operations
�Trial/continuous cuts�Tool preparations �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 multitasking machines, to help them create smoother and more effective ways of producing parts. Novice operators as well as professional machinists get complete control—and satisfaction.
�Easy tool registration
� Standard Specifications
� Optional Specifications
With spreadsheet simplicity–tool offsets, tilt, shape, life, etcNall the tool data required to cut a part can be registered here.Since the registered tool data is also used by Okuma auto programming (AdvancedOne-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.
Super-NURBS is a high-speed NC function with “sculptured-surface adaptive acceleration control” for high-accuracy, high-quality, and high-speed machining of all types of curved surfaces.
Tool machining paths are set to be easy on the machine, resulting in smooth movements with respect to the command paths of the machining program. By accelerating and decelerating tool movement based on these smooth machining paths, shocks and vibrations to the machine and drive system during high-speed feed are greatly reduced and high-speed acceleration and deceleration are achieved to draw out the highest machine performance.

When it is difficult to program feedrates for die-making and you need different feedrates for specific cutting patterns, you can simply program using feedrate numbers. Choose either the rotary switch or the keyboard type F1 parameters.
A full selection of software for advancedmachining applications
Your factory needs are the specifications our OSP systems do best
• Previous part programs can be used as is.• It provides stable control that always guarantees the specified machining accuracy even if the feedrate and other cutting
conditions are changed.• Functions such as sequence recovery, manual interrupt, and feed override change can be easily operated in the same
way as in standard NC machining.• Control modes such as machining efficiency priority or machined surface quality priority can be selected in accordance
with the machining application (rough, semi-finish, finish).• It also responds to NURBS commands.

To protect your factory and equipment from fire and assure continued safe operation, observe the following fire safety precautions whenever you operate machinery. Whenever possible, avoid the use of oil-based coolants for cutting operations. Sparks caused by hot chips, tool friction, and grinding can cause fires. Always observe the following safety measures to ensure safe operation when machining flammable materials or when performing dry machining.
Before machining any material designated by law as a flammable substance, e.g., plastic, rubber, wood, acquaint yourself with the special characteristics of the material in terms of fire prevention, and observe the precautions given in (2) above to ensure safe operation. Example: When machining magnesium, there is a danger that magnesium chips and water-soluble coolants will react to produce hydrogen gas, resulting in an explosive fire if any chip should ignite.
Dry machining is a fire hazard because workpieces, tools, and chips are not cooled. To ensure safe operation, do not place any flammable objects near the machine and do not allow chips to over accumulate. In addition, be sure to check cutting tools to make sure of their service life and the condition of the tool edge, and observe the precautions regarding oil-based coolants given in (2) above.
(1) Use nonflammable cutting fluid coolant. (2) When the use of an oil-based coolant is unavoidable:
Before you begin machining, check cutting tools to make sure of their service life and the condition of the tool edge, and choose cutting conditions that will not cause a fire. Periodically clean the coolant filter to maintain sufficient coolant discharge, and frequently verify that coolant is discharging normally. Take measures to control the outbreak of fire: Place a fire extinguisher near the machine, have an operator constantly monitor operation, and install an automatic fire extinguishing system. Do not place flammable materials near the machine.Do not allow chips to over accumulate. Periodically clean the inside of the machine and the area surrounding it.Check that the machine is operating normally. Never run the machine unattended. Since an automatic fire extinguishing system and other peripherals are needed for grinding operations, please let us know as soon as possible if you plan to perform such operations.
