1. Innovative, Rigid Structure
The core foundation of this machine is a marvel of engineering, exhibiting unparalleled strength, supreme stability, and enhanced architectural integrity. Constructed from high-strength, wear-resistant cast iron, the primary castings undergo numerous aging treatments to completely eradicate internal stress. These robust guide rails boast exceptional wear resistance, guaranteeing elite precision and a prolonged operational lifespan.
2.Exceptional Grinding Head
This state-of-the-art machine incorporates a high-precision spindle system, originally crafted by a renowned Taiwanese manufacturer celebrated globally. The spindle is engineered with P4-level ultra-precision bearings, with taper end deflection meticulously controlled within 2µm. It is driven by a V-3-level low-vibration motor, ensuring high-speed rotation with minimal noise and zero vibration, coupled with an impressive load-bearing capacity. Perfectly suited for heavy-duty cutting and a variety of molding grinding applications.
3.Precision-Engineered Feed Structure
The machine's advanced slides moving front, rear, left, and right are equipped with premium imported guide rail wear-resistant sheets, TUR CITE-B, and are expertly precision-scraped to maintain superior accuracy. The column and spindle head guide rail are in perfect harmony with high precision, making it the ideal choice for precision forming grinding across diverse groove configurations.
4.Efficient Automatic Lubrication System
Initiating the spindle activates the lubrication pump, which automatically and seamlessly lubricates all screws and sliding surfaces, significantly minimizing wear and prolonging operational accuracy and lifespan.
5.Advanced Safe Dust Protection System
To ensure ultimate protection, dust-proof components are integrated between each moving part. The sophisticated sheet labyrinth rubber guards offer comprehensive safety for the guide rails, maintaining a pristine, dust-free, and moisture-free environment within the system.
1. Precisely Engineered Grinding Head
The manual grinding head, enhanced with a rapid lifting mechanism and powered by an integrated motor, exudes superior rigidity and precision.
2. Effortless Electromagnetic Chuck
Designed for simplicity and efficiency, the electromagnetic chuck operates with ease, conserving valuable time while boasting the ability to function continuously for over 20 hours.
3. Precision Metal Hand Wheel
Crafted for precision, the high-accuracy metal feed handwheel offers effortless control, supporting grinding models with an impressive accuracy of 0.002MM.
4. Superior Double V Guide Rail
Employing a longitudinal Double V guide rail and a lateral single V flat guide rail, this innovative hydraulic drive system ensures high precision and seamless operation.
5. Robust Resin Sand Cast Iron Body
Expertly crafted castings offer remarkable stability and strength, subjected to artificial aging treatments to preserve dimensional accuracy during finishing processes.
