Characteristics of OKUMA components:
OKUMA inverter
An inverter (inverter) is a device that converts direct current to alternating current, allowing voltage and frequency regulation.
Advantages of OKUMA inverters:
- Provide protection for motors against overloads and short circuits.
- Optimize production processes by adjusting operating parameters to meet current needs, which improves industrial process management and increases efficiency.
- Integration with control systems to enable monitoring, automation and advanced real-time control.
OKUMA ruler
A ruler is a component of a measuring system used in CNC machines
Advantages of OKUMA scales:
- High precision measurement to ensure machine positioning accuracy, which increases production quality and minimizes errors
- Increased reliability, thanks to the elimination of errors related to vibration or wear, which improves the life of equipment and reduces the risk of failure.
- Resistance to external conditions such as vibration and temperature changes.
OKUMA Head
A head is a component used in the brand’s CNC machine tools, such as lathes and machining centers. It can refer to the turret head, where cutting tools are mounted, or to the spindle head, responsible for rotating the workpiece.
Advantages of OKUMA heads:
- Precision machining for high quality detail finishes.
- Versatility of application enabling various cutting operations such as turning, milling and drilling.
- Compatibility with various control systems
