Herbao Machinery Exhibits at TMTS 2026 Showcasing High-Precision Rotary Tables and 5-Axis Machining Applications Herbao Machinery participated in TMTS 2026 – Taiwan International Machine Tool Show, held from March 25 to 28, 2026, at the Taichung International Convention & Exhibition Center. At Booth H0211, we presented the versatile applications of our high-precision rotary positioning tables across multiple industries.This year’s exhibition highlighted applications in automotive component machining, electronics manufacturing, consumer product processing, and automation integration, demonstrating the critical role of rotary positioning technology in modern smart manufacturing. Rotary Positioning Tables: The Precise Integration of Force and Angle The core of a rotary positioning table lies in the precise integration of force and angular control, enabling stable and accurate machining performance.As industry demand continues to grow for multi-angle machining, complex surface processing, and high-cycle production, rotary positioning tables have become essential components in CNC machining, automated production lines, and 5-axis applications. Automotive Industry: Micron-Level Machining of Ball Joints In vehicle wheel systems, drivetrain assemblies, and steering mechanisms, the ball joint is a critical component. By combining a lathe with rotary positioning functionality, one-time turning can be achieved, allowing the spherical surface to reach micron-level precision and ensuring smooth motion and long-term durability. Electronics Industry: Multi-Angle Bonding in Smartphone Manufacturing Modern smartphones feature complex internal structures that require precise multi-angle bonding processes. Through the integration of 5-axis synchronization and dispensing equipment, adhesive volume and bonding angles can be accurately controlled, improving assembly precision and yield rates. Consumer Products: Embossing and Roller Engraving for Face Masks The text and embossed patterns on face masks are produced using a machining center equipped with a 4th-axis rotary device for roller engraving. Combined with high-temperature and high-pressure continuous rolling production, this process achieves both precision and high-speed, cost-effective mass production. Versatile Applications Enhancing Overall Production Efficiency At TMTS 2026, we not only showcased individual equipment capabilities but also emphasized the extensive application potential of rotary positioning tables across multiple industries, processes, and equipment integrations.With high-rigidity structural design, stable positioning accuracy, and multi-angle operational capability, rotary positioning tables help manufacturers： Improve machining precision Enhance production efficiency Reduce process errors Increase production line flexibility Support automation integration In an era where smart manufacturing and energy efficiency are increasingly important, efficient and stable rotary control technology has become a key driver in industrial upgrading. Looking Ahead Herbao Machinery will continue to focus on the research and innovation of high-precision rotary positioning table technology, assisting customers in responding to dynamic market demands and building more competitive machining solutions.We sincerely appreciate all visitors who stopped by our booth at TMTS 2026. We look forward to future collaborations and to continuously creating greater efficiency and precision value for the industry.     https://www.herbao.com.tw/en/hot_532548.html TMTS 2026 Taiwan International Machine Tool Show | 5-Axis Machining and Automation Integration Applications 2026-04-17 2027-04-17

Electrical Discharge Machining - Wire EDM
The Top Choice for Complex Part Processing


 What is Wire EDM？ 
Wire EDM is a thermal process widely applied in the precision manufacturing of parts across various industries. This section delves into the functions of Wire EDM and its role in the manufacturing sector, especially when paired with rotary positioning tables.

 Wire EDM Process 

Also known as EDM or WEDM, Wire EDM is a precise machining method that uses thermal energy to remove material from a workpiece. Known by various names such as spark erosion and wire erosion, the process involves a fine metal wire and deionized water to cut metal and prevent rusting. The wire, usually made of brass or layered copper, acts as the tool electrode and follows a pre-defined path to shape the workpiece.
 History of Wire EDM 

The phenomenon of electrical discharge erosion was first observed in 1770 by British physicist Joseph Priestley, who termed it electrical discharge erosion. In 1967, the Soviet Union developed the first commercially available digital-controlled Wire EDM machine.

 
 Types of Wire EDM 

Wire EDM is categorized into fast wire, medium wire, and slow wire EDM. Fast wire EDM operates at speeds of 6 to 12 m/s, with high-speed reciprocating movement of the electrode wire but lower cutting precision. Medium wire EDM, an evolution of fast wire EDM, introduces frequency control for multiple cuts, a newer process developed in recent years. Slow wire EDM features a wire speed of 0.2 m/s with low-speed unidirectional movement, offering high cutting precision.

Types and Sizes of Wires Used in Wire EDM

Wire EDM uses metal wires with diameters ranging from 0.0008 to 0.013 inches. Thinner wires require lower power settings and cut at slower speeds. Commonly, brass wires with a diameter of 0.010 inches are used.
Shape of Workpieces

Wire EDM can cut small and complex shapes. For handling multiple flat parts, stacking workpieces can enable efficient, unattended batch processing.

Materials for Wire EDM

This technology is extensively used in various industries. Pre-hardened mold steel is ideal for CNC Wire EDM, maintaining shape integrity without post-machining heat treatment. Titanium, known for its excellent conductivity, is well-suited for Wire EDM, generating minimal heat during the process and maintaining dimensional accuracy. Austenitic stainless steel, with its corrosion resistance and high thermal conductivity, ensures tool sharpness and prevents thermal damage. Tungsten and molybdenum, with high melting points, can withstand the high temperatures of EDM.

Applications of Wire EDM 

Wire EDM technology, combined with rotary positioning tables, finds broad applications across industries.

Component Processing

In conponent processing industries, Wire EDM can manufacture parts with precise tolerances and complex shapes. High-precision rotary positioning tables enhance the ability to machine spiral and gear-like parts, acting as work exchange tables for accurate multiple part processing.

Medical Devices

Wire EDM offers the precision needed for producing complex medical instruments, ensuring the efficacy and compatibility of medical devices by meeting stringent regulations.

Electronics

Wire EDM effectively produces microelectrodes used in microelectronics for circuits and sensors, where precise tolerances are critical for functionality.

Mold Tooling

Wire EDM can rapidly shape mold inserts, ensuring accurate reproduction of intended plastic parts. It’s also used to make stamping dies, extrusion molds, cutting punches, and more.

 Conclusion 

Wire EDM is a precise and efficient machining process that, when paired with rotary positioning tables, expands the range and scope of processing capabilities, making it ideal for various industries' complex shapes. Compared to many other manufacturing processes, it offers greater accuracy, efficiency, and cost-effectiveness, enhancing manufacturing competitiveness.
