1. Robust and Durable Construction
This machine boasts an exceptionally strong base column structure, renowned for its impressive strength, robust architecture, and unparalleled stability. Crafted from high-strength, wear-resistant cast iron, the main castings undergo multiple aging treatments to completely eliminate internal stress, ensuring superior durability. The guide rails, designed for high wear resistance, guarantee precise operations and extend the machine's lifespan significantly.
2.Premium Grinding Head Engineering
Our machine features a high-precision spindle system, sourced from a world-renowned Taiwanese manufacturer. The spindle is equipped with P4-level ultra-precision bearings, maintaining taper end deflection within a remarkable 2µm. Coupled with a V-3-level low-vibration motor, the system operates at high speed with minimal noise and no vibration, supporting high load-bearing capacities. This makes it ideal for heavy-duty cutting and diverse molding grinding tasks.
3.Precision Feed Mechanism
This machine's front and rear, left and right slides are endowed with premium imported TUR CITE-B guide rail wear-resistant sheets, precision scraped to uphold superior precision. The column and spindle head guide rail pairing is optimized for high accuracy, making it perfect for the precise forming grinding of various grooves.
4.Innovative Automatic Lubrication System
Upon activating the spindle, the lubrication pump automatically engages, delivering lubrication across all screws and sliding surfaces. This reduces wear and extends both the machine's accuracy and lifespan, ensuring consistent performance.
5.Comprehensive Dust Protection System
Strategically installed dust-proof components safeguard each moving part, featuring sheet labyrinth rubber guards that protect guide rails, maintaining a pristine, dust-free, and water-free interior environment.
1. Precision Grinding Head
The manual grinding head, equipped with a rapid lift mechanism and a built-in motor, exemplifies excellent rigidity and precision, enhancing your grinding efficiency.
2. Efficient Electromagnetic Chuck
User-friendly operation saves valuable time, with the capability to function continuously for over 20 hours, enhancing productivity significantly.
3. Precision Metal Hand Wheel
Featuring a high-precision metal feed handwheel, this component offers effortless control. It delivers exceptional grinding accuracy of 0.002MM, ideal for precision tasks.
4. Advanced Double V Guide Rail
Employing a longitudinal double V guide rail and a lateral single V flat guide rail, combined with hydraulic drive, this system ensures elevated precision and reliability.
5. Resilient Resin Sand Cast Iron Body
With castings characterized by remarkable stability and strength, the artificial aging treatment guarantees dimensional precision in the finishing of castings, enhancing overall machine performance.
