1. Highly Rigid Structure
The foundation of our machine boasts unparalleled strength and stability, with a robust base column structure designed for exceptional durability. Crafted from top-grade, wear-resistant cast iron, the main castings undergo multiple aging treatments to thoroughly eliminate internal stress, ensuring unparalleled precision and longevity. The guide rails, renowned for their superior wear resistance, deliver consistently high accuracy and extend the machine's lifespan, making it an invaluable asset in industrial metal use.
2.High-Quality Grinding Head
Our machine is equipped with a world-renowned high-precision spindle system sourced from a leading Taiwanese manufacturer. Utilizing P4-level ultra-precision bearings, the spindle maintains taper end deflection within an impressive 2µm. Powered by a V-3-level low-vibration motor, the machine achieves high-speed rotation with minimal noise and vibration, while supporting substantial loads. It excels in heavy-duty cutting and diverse molding grinding applications, setting new standards in performance and reliability.
3.High-Precision Feed Structure
Our machine features front and rear left-right slides enhanced with premium imported TUR CITE-B wear-resistant sheets. These are precision scraped to ensure exceptional accuracy. The column and spindle head guide rail are meticulously matched, offering unrivaled precision, making it perfect for detailed groove forming and precision grinding tasks.
4.Automatic Lubrication System
Upon spindle activation, the lubrication pump automatically begins lubricating all screws and sliding surfaces, significantly minimizing wear and maximizing both accuracy and operational lifespan. This advanced system ensures seamless operation and sustained performance.
5.Safe Dust Protection System
Our innovative dust-proof components, including protective rubber guards, are strategically placed between moving parts. The sheet labyrinth design effectively shields guide rails, ensuring a clean, dust-free, and water-resistant interior, thereby safeguarding the machine's integrity.
1. Grinding Head
This manual grinding head, equipped with a rapid lifting mechanism, features a built-in motor. The spindle is engineered for superior rigidity and precision, optimizing performance across various applications.
2. Electromagnetic Chuck
User-friendly and time-efficient, our electromagnetic chuck boasts continuous operation for over 20 hours, enhancing productivity and efficiency in demanding industrial settings.
3. Metal Hand Wheel
The high-precision metal feed handwheel offers effortless control with an impressive accuracy of 0.002MM. It is designed for precision grinding models, ensuring superior results with every use.
4. Double V Guide Rail
Featuring a longitudinal double V guide rail and lateral single V flat guide rail, our machine employs hydraulic drive for exceptional precision, redefining standards in accuracy and reliability.
5. Resin Sand Cast Iron Body
Constructed with resin sand cast iron, our castings ensure remarkable stability and strength. Undergoing artificial aging treatment, they maintain dimensional accuracy in finishing, offering long-lasting performance and dependability.
