In precision machining environments,the MIV22A-1-B5 ensures smooth acceleration,minimal vibration,and reliable thermal performance.Its compact footprint and rugged design allow it to fit neatly into control cabinets,contributing to space efficiency and streamlined wiring.Widely recognized for its reliability and performance,it remains one of the most trusted spindle drive solutions in modern industrial automation.

Core Advantages and Technical Highlights

Integrated control logic for faster response:

The MIV22A-1-B5 features an embedded processor that handles motor control logic directly on the unit.This eliminates the need for external control modules and shortens processing time,resulting in more accurate spindle positioning and improved machining precision.

High-output spindle power:

Delivering 22 kW continuously,the MIV22A-1-B5 meets the torque and speed demands of high-inertia applications.Its stable power output ensures excellent performance in operations such as gear roughing,mold milling,and large-part turning.

Modular and compact design:

Despite its power,the drive maintains a relatively small footprint,making it suitable for retrofitting into existing panels.The modular layout simplifies installation and maintenance,reducing overall downtime during equipment upgrades.

Advanced communication interfaces:

With support for servo link,encoder link,and converter link protocols,the MIV22A-1-B5 facilitates real-time synchronization between the drive and the CNC controller.This ensures stable speed control and accurate feedback from the spindle motor.

Built-in protection features:

The drive includes integrated safeguards against over-voltage,over-current,and thermal overload.These functions prevent unplanned shutdowns,contributing to system longevity and operator safety.

Robust cooling and heat dissipation:

An internal fan and ribbed heat sink provide consistent cooling under full load conditions.This ensures thermal stability,even in continuous or high-speed operations over long production cycles.

Compatible with legacy and current systems:

Designed to operate seamlessly with Okuma’s OSP control platforms and VAC motors,the MIV22A-1-B5 ensures excellent backward compatibility,helping users maximize their existing investment in Okuma machinery.

Application Areas

The MIV22A-1-B5 finds widespread application across industries where high spindle torque and precision are essential.In the aerospace sector,it is often used for titanium and Inconel machining,where material resistance demands stable power delivery and minimal vibration.Its performance under load ensures smoother surface finishes and accurate dimensional tolerances.

In the automotive industry,the MIV22A-1-B5 powers spindles for transmission housing milling,cylinder block boring,and crankshaft machining.Its ability to maintain torque across varying speeds supports uninterrupted production and extended tool life.

The MIV22A-1-B5 is also commonly deployed in tool and die manufacturing,especially for deep cavity machining in molds and dies.Its precise spindle control is vital for fine detailing and surface texture quality.

System integrators and MRO teams rely on the MIV22A-1-B5 to restore aging Okuma systems,due to its drop-in compatibility with older drive racks.This drive allows plants to extend machine lifespan while achieving performance close to that of new installations.
