Since establishing its base in Taichung in the early 1990s, the company has adhered to the philosophy of “Maintain and Continuously Improve.” Starting from manual and semi-automatic machines, it has progressively advanced to NC/CNC control and double-column models, building a complete surface grinding machine product line. These machines are widely applied in industries such as aerospace, automotive, mold manufacturing, semiconductors, and general machinery, offering customized solutions.
Product Series and Features
Rotary Surface Grinding Machines (HR Series)
Horizontal and vertical rotary types (e.g., HR-200–300, HR-400–600) feature Meehanite cast-iron beds, AC servo motors, AND/CNC controls, and powerful magnetic chucks to ensure machining rigidity and stability.
NC/CNC Precision Surface Grinding Machines (DSG Series)
Multi-axis control models (e.g., DSG-820~2480ANDⅡ/CNC) are equipped with linear roller guideways, AC servo ball screws, full-enclosure guarding, and high-rigidity structures, suitable for large or high-precision workpieces.
Vertical Long-Travel and Double-Column Grinding Machines (VSG Series)
Long-travel vertical grinders (e.g., VSG-4000) use rack-and-pinion drives with roller guideways, ideal for processing large plates, quartz, or ceramic substrates.
Semi-Automatic and Fully Automatic Specialized Grinding Equipment
Custom-designed with automatic feeding and automatic wheel dressing functions, these machines are suited for mass production or special material processing, improving productivity.
Technological Evolution and Industry Overview
Grinding machine control systems have evolved from relying on skilled operators for manual operation, to digital NC, and now to modern CNC. Today’s CNC systems feature multi-axis control, CAD/CAM integration, automatic loading/unloading, and machining compensation functions, greatly enhancing machining precision and productivity while meeting the needs of smart manufacturing.
Precision surface grinders represent a major market segment, accounting for over 66% of the total market. High precision machining demand from automotive, aerospace, and electronics industries continues to drive market expansion, with the automotive sector being the largest end-user, accounting for more than 25%.
Why Is “High-Precision Surface Grinding” So Critical?
Precision grinding achieves extremely tight tolerances (e.g., ±0.0001 inch) and exceptional surface finishes (around 10 RMS), which are crucial for perfect fit between mechanical components. Ground parts not only offer high dimensional accuracy but also smoother surfaces, reducing wear and friction, extending component lifespan, and improving overall product performance.
It is essential for supporting advanced technology applications—such as electronics, aerospace, and medical devices—where stringent dimensional and precision requirements must be met. In sectors like semiconductors, aviation, and medical equipment, precision grinding ensures components meet rigorous specifications.
What Added Value Does a “CNC Surface Grinder” Provide?
A CNC system controls wheel speed, path, and feed rate to ensure every machining operation is executed with pinpoint accuracy—ideal for applications requiring micron-level tolerances.
CNC machines also offer multi-axis motion, automatic tool change, and in-process measurement, making them particularly suitable for manufacturing complex geometries or high-volume production. By delivering repeatable, high-precision machining, they reduce scrap rates, rework costs, and shorten production cycles, significantly contributing to manufacturing efficiency.
Conclusion
From its foundation in the early 1990s, the company has advanced from manual and semi-automatic machines to a full line of NC/CNC surface grinders, embodying its guiding principle of “Maintain and Continuously Improve.”
Aligned with global market dynamics and industry trends, these high-precision, intelligent grinding technologies meet the needs of aerospace, automotive, mold, semiconductor, and other industries, while laying a solid foundation for enhanced efficiency and quality control in the manufacturing environments of the future.
