Heavy-duty spindle, Japanese NTN heavy-duty bearing

 

The headstock and gearbox come standard with oversized NTN support bearings, offering key advantages in the drive system:
Heavy-duty, impact-resistant bearings:

Capable of withstanding prolonged stone-cutting loads, these bearings prevent spindle breakage and wear, significantly extending maintenance intervals and reducing downtime for repairs.
Constant pneumatic pressure output:

Integrated with the machine's dual-circuit pneumatic control system, this ensures stable, consistent polishing pressure, resulting in a uniform, lustrous finish across the stone surface without uneven shading or color variations.

Original Italian COMES Grinding Head Assembly (2 Calibrating Heads + 22 Polishing Heads)

 

Uniform Slab Thickness:
Equipped with two Italian calibrating heads at the front to precisely calibrate slab thickness, ensuring uniformity across the entire slab and laying the foundation for subsequent mirror polishing.
Integrated Flexible Cushioning Protection:
The grinding heads feature a built-in flexible cushioning structure that absorbs shock and vibration when processing thin slabs, fragile luxury stones, or irregularly shaped pieces, significantly reducing the risk of chipping, breakage, or material loss.

Mechanical Structure

Enlarged 170mm Spindle Box

Double-layer anti-corrosion coating; Upward cylinder design for ample maintenance space; Half the maintenance time.

Double-layer Tabletop with Added Stainless Steel Plate

Double-layer tabletop with stainless steel plate to prevent rust, reduce friction, ensure smoother belt conveying, reduce tabletop wear for greater durability, facilitate replacement and maintenance, and extend the overall machine's lifespan.

Stainless Steel + High-Temperature Painted Sheet Metal

Rust-proof and corrosion-resistant, maintains its new appearance for a long time; easy to clean with stone powder and mud; High-end and clean equipment appearance.

Enlarged Conveyor Roller Bearings

Enlarged bearings prevent excessive belt tension from breaking the shaft and damaging the bearings.

18.5 kW permanent magnet main motor with variable frequency control

• Energy-efficient: saves 20%–30% on electricity costs year-over-year:

Compared to traditional asynchronous motors, permanent magnet motors paired with variable frequency drives reduce electricity costs by 20%–30%; the energy-saving effect is significant, resulting in substantial cost savings over long-term use.

• Capable of continuous, long-term operation with stable performance:

The permanent magnet motor operates with a low temperature rise, allowing for prolonged, continuous operation. It supports two-shift schedules with stable performance and no restrictions on operating duration. Variable-frequency soft starting ensures there is no impact on the power grid.

• Low maintenance costs:

Speed ​​regulation is smooth; the mill's rotational speed can be adjusted according to material hardness, thereby reducing equipment impact and vibration, extending the service life of internal motor components, and ensuring a low failure rate.

Dual-gas-path pressure control

• Independent dual-gas-path pressure regulation

Features dual-mode air pressure-high pressure for rough grinding and cutting, and low pressure for gentle, precision polishing-to accurately meet specific process requirements.Eliminates edge chipping and corner breakage on thin sheets, with stable air pressure output unaffected by fluctuations in the air supply.

• Grinding head hovering and cushioning

Features a hovering buffer function: when grinding slabs with missing corners, the grinding head hovers, and its rapid vertical response ensures effective edge grinding, prevents scratching the stone, minimizes impact on the slab surface, and reduces the risk of breakage for luxury stone-thereby cutting down on consumable waste.

Independent single-head adjustment + station control

• Independent Single-Head Edge Polishing Sequence
• Configure the polishing duration for both sides of the board.
• Eliminate gloss inconsistencies-such as a matte finish at the ends and a glossy finish in the middle-to ensure uniform edge brightness and enhance the overall polishing quality of the board surface.

The rotational speed and direction of each grinding head can be adjusted independently.

• The rotation speed of each grinding head can be adjusted independently to suit specific materials, ensuring optimal grinding and polishing results; the system is widely used for materials such as luxury stone, engineered quartz, marble, and granite.
• The rotation direction of each head is independently controllable; adjacent heads rotate in opposite directions with overlapping paths, eliminating surface grinding marks and shadows while enhancing the overall finish.

One-touch adjustment for board thickness variations

automatic, real-time monitoring of abrasive wear.

• One-touch automatic adjustment of grinding plate thickness offers convenience and speed while saving abrasive material.

Each grinding head features a precision-controlled lifting mechanism, resulting in significant abrasive savings. Adjusting for variations in slab thickness is quick and convenient, requiring only a simple input via the computer interface. In contrast, traditional grinding machines require manual adjustment of the upper and lower limits for each head, a process that is labor-intensive and wastes abrasive material.

• Automatically monitor abrasive consumption in real time.

The remaining abrasive thickness is monitored in real-time with millisecond-level data updates displayed on the screen, enabling precise control over abrasive usage and resulting in significant annual cost savings.
The system provides early warnings for low abrasive levels, halts the machine when the abrasive is exhausted, and automatically lifts and locks the grinding head upon depletion for protection.

High Operational Stability:

Three-section split beam + NTN heavy-duty bearings + a complete set of imported electrical and pneumatic components support uninterrupted 24/7 mass production, with a failure rate far lower than traditional single-beam mills.

Superior Quality in Luxury Stone Processing:

Off-peak vibration reduction, independent parameter control per head, and abrasive monitoring solve four major industry pain points: vibration marks, color difference, chipping, and missed polishing.

Digital Intelligent Management:

Yonghong PLC + Weintek remote touch control provides full traceability of production, consumable, and fault data, supporting integration with factory MES systems.

Lower Long-Term Maintenance Costs:

Permanent magnet motor saves 20%-30% on electricity; abrasive monitoring saves on consumables; top-mounted cylinder + automatic lubrication reduces maintenance; stainless steel painted body is corrosion-resistant and durable.

Wide Material Compatibility:

Compatible with translucent soft luxury stone, thin slabs, granite, and irregularly shaped slabs with missing corners, suitable for mass production in high-end home decoration and hotel projects.
