Special Seminar on Press Die Machining by CGS × Okuma × Sodick × Komatsu Industries!
“Innovation Seminar ~ Discover the Latest in Die Manufacturing~”
28/10/2025
Samurai Asia Editorial Department
In February 2025, CGS ASIA released “EXCESS-HYBRID II” Ver.10, a CAD/CAM software specialized for press die design and manufacturing. To showcase its new capabilities and real-world applications when combined with various machine tools, a special seminar was held on August 21, 2024, at Novotel Bangna, attracting approximately 70 guests from companies involved in die design and manufacturing. The seminar was co-hosted by three leading machine tool manufacturers — Okuma, Sodick, and Komatsu Industries — each of which also presented their technologies and exhibited machinery at the event.
CGS ASIA｜EXCESS-HYBRID II Ver.10 for Press Die Design and Manufacturing
The latest version, Ver.10, introduces new functions that enhance work efficiency, including advanced file management, design assistance, and verification tools, further shortening machining time. A newly added “Chamfering Function” also enables deburring and edge finishing with spherical tools, expanding flexibility in precision processing.
■ File Selector
The new File Selector allows users to register favorite file paths by format for quick access. This enables faster data retrieval from specific folders directly within the software.
■ Fillet / Chamfer
Users can input chord width values to create fillets and chamfers with a consistent visible width, improving design precision.
■ Deburring Curve
A new deburring command for spherical tools allows users to define cutting direction, tool diameter, and chamfer amount to automatically generate a wire body usable as a toolpath.
■ Curvature
The new curvature display visualizes contours of convex and concave areas, showing radius and curvature differences. Maximum and minimum curvature values can be extracted, supporting optimal tool diameter selection.
It also supports machining of multiple workpieces, allowing you to specify workpiece coordinates in advance. Easy-to-understand operability allows you to efficiently set machining steps.
In addition, CGS ASIA introduced the “3D CAD Option” , a feature designed to further accelerate and streamline the mold design process.
SODICK │ World’s First Automatic Wire Rotation Mechanism “iGroove+”
Sodick develops its own core technologies, including linear motors and K-SMC (Discharge and Axis Control), to deliver high-precision and highly stable wire electrical discharge machines (EDM).
The “iGroove+ Edition” introduces the world’s first technology that automatically rotates the wire during finishing processes, reducing wear and enabling finishing with a consistently unworn wire surface.
Features of iGroove+ Edition (Wire EDM)
・Reduced Production Costs:
The iGroove wire rotation mechanism minimizes wire consumption by ensuring that finishing is always performed with an unworn surface.In addition, an energy-saving pump is included as standard, reducing overall power consumption.
・Uniform Surface Finish from Top to Bottom:
The system suppresses streaking and unevenness often seen in thick workpieces, improving surface quality and reducing the need for manual finishing in post-processing.
・High Stability and Accuracy:
With digital HF discharge control, the machine maintains stable processing performance even when water quality or workpiece thickness changes, ensuring a consistent, high-quality surface finish.
Ideal Applications
The iGroove+ Edition is ideal for mold manufacturing, high-precision components, and thick workpieces requiring uniform surface quality throughout the entire height of the workpiece.
Example applications: motor core molds, electronic component molds, and other precision tooling.
OKUMA Techno │ Energy-Saving and Eco-Friendly Manufacturing Solutions
Okuma Techno (Thailand) introduced a range of environmentally conscious and energy-efficient technologies, including the Thermo-Friendly Concept, Servo Navi, and Hyper-Surface, all designed to improve machining precision, productivity, and sustainability.
What is the Thermo-Friendly Concept?
The Thermo-Friendly Concept is Okuma’s proprietary thermal deformation control technology, which integrates machine design with CNC control systems. It enables high-precision and stable machining even under environments with significant temperature fluctuations.
Key Features:
Reduced operator workload and cost efficiency:
No need for machine warm-up or temperature stabilization before operation. Manual adjustments or corrections are unnecessary, ensuring dimensional accuracy and consistent surface quality even during long production cycles.
What is Servo Navi?
Servo Navi is an intelligent control system that automatically optimizes the motion of each machine axis.
It detects and compensates for variations in workpiece or fixture weight, improving production speed and machining accuracy — ideal for heavy workpieces.
Key Features:
▲ ServoNavi usage example
・Work Weight Auto Setting:
Automatically estimates the weight of the workpiece and fixture to optimize servo parameters and acceleration, maintaining accuracy while reducing machining time.
・Reversal Spike Auto Adjustment:
Corrects reversal spikes caused by wear, enhancing machining stability and product quality.
・Vibration Auto Adjustment:
Automatically adjusts servo control in response to vibration or abnormal noise, reducing sound levels and extending machine life.
Hyper-Surface is a CNC-integrated control function that automatically detects irregular toolpaths and feed rate variations from CAM data and corrects them directly within Okuma’s CNC system. It produces smooth surface finishes without the need to modify CAM code.
This significantly reduces polishing time and manual labor, making it ideal for parts that require high surface quality, such as molds, aerospace components, and free-form surfaces.
