Typical Application Scenarios
The OKUMA MIV15-1-B5 is a versatile and robust servo drive,making it a critical component across various industrial applications that rely on Okuma CNC machinery for precise single-axis motion control.
In the general machining sector,the OKUMA MIV15-1-B5 is widely utilized in CNC lathes,milling machines,and grinding machines where a single axis(e.g.,X,Y,Z,or B-axis)requires precise and powerful control.For instance,in a turning center,it can precisely control the linear movement of a carriage or turret,ensuring accurate positioning for cutting operations,achieving intricate profiles,and maintaining tight dimensional tolerances on turned parts.Its 15 kW capacity handles substantial cutting forces,enabling efficient material removal.
For specialized automated equipment and material handling systems,the OKUMA MIV15-1-B5 proves invaluable in controlling individual linear or rotary axes.This could include controlling the precise movement of a robotic arm’s joint,a conveyor belt’s speed,or a gantry system’s positioning.The drive’s high power and accuracy ensure smooth,repeatable motion,which is crucial for tasks like precise pick-and-place,assembly,or automated inspection where consistent and fast movements are required.
In woodworking and heavy-duty routing applications,the OKUMA MIV15-1-B5 is applied to precisely control the high-speed routing spindle or an individual axis of a large CNC router.The drive’s ability to maintain high torque and stable speed is essential for cutting through dense materials and achieving intricate designs with a smooth finish,particularly where continuous operation under heavy load is common.
Furthermore,in additive manufacturing or 3D printing systems,particularly those utilizing large-scale or industrial-grade printers,the OKUMA MIV15-1-B5 can control a single build platform axis or extrusion head axis.Its precise control over movement ensures layer-by-layer accuracy,which is fundamental to the integrity and quality of the printed part.The compact design of the OKUMA MIV15-1-B5 also makes it suitable for integration into systems where space is at a premium without compromising on the required power and precision.
