New Release--Horizontal Edge Grinding Polisher Machine

The Horizontal Edge Grinding Polisher Machine is a professional automated processing equipment used for fine processing such as grinding, polishing, chamfering on the edges of flat workpieces. It is widely used in the deep processing industries of stone, ceramics, glass, and sintered materials,  is a core piece of equipment for realizing the design and processing of stone edges to improve edge quality and processing efficiency. 

Its core feature lies in its horizontal structure-the workpiece is stably transported via a horizontal conveyor belt (or vacuum adsorption conveying system) and continuously processed through multiple sets of grinding heads. Unlike vertical models, the horizontal design can process large-sized workpieces.

The equipment operates on a highly automated principle: it is typically controlled by a PLC system with a touchscreen interface. The workpiece is automatically fed in, and the grinding head rotates at high speed to process the edges. The entire process requires no frequent manual adjustments, achieving integrated operation from feeding to finished product output.

"ZhongLi" 14-Heads Edge Grinding Polisher Machine is introduced recently. There are specifications as below: 

1. introduction of 14-Heads Edge Grinding Polisher Machine:

This machine adopts numerical control feed adjustment, adopts diamond wheel shaping and water grinding piece polishing when processing stone, and is equipped with snail buckle and joint, which can grind the right-angled bottom edge and thickening edge of all kinds of flat stone according to different size and thickness of stone. The forming and rough grinding and polishing process of machinable stone side and small upper and lower bevel angle, 45°chamfer and round edge can be completed at one time. The brightness of the processed product is the same as that of the board. The structure of this machine is advanced and reasonable. The utility model has the advantages of high precision, high efficiency, convenient operation and simple maintenance. According to the machining requirements, the feed speed and the feed rate of the grinding head can be adjusted in the grinding process. When the machine is in normal use, it is equivalent to the workload of 20 people in normal stone processing, and the technological defects caused by manual processing are eliminated.

Daily Maintenance Points ( 14-Heads Edge Grinding Polisher Machine)
The 14-Heads Edge Grinding Polisher Machine has more functional components, so it is necessary to follow exclusive maintenance parameters to ensure stable operation and extend the service life (target service life ≥8000 working hours). The following are detailed maintenance points with exclusive parameters:

Daily maintenance (after each shift, mandatory)

- Clean the equipment: Use high-pressure water (pressure ≤0.3MPa) to flush the 14 grinding heads, conveyor belt, and water tank; wipe the touch screen and control panel with a dry cloth to avoid water damage; clean the dust collection filter (filter fineness 10μm) and ensure the air intake is smooth;

- Check grinding heads (exclusive replacement cycle): Observe the wear of each grinding head: rough grinding heads (diamond grinding wheel, particle size 80#-120#) replacement cycle 200-250 working hours; fine grinding heads (diamond grinding wheel, particle size 200#-400#) replacement cycle 300-350 working hours; polishing heads (resin polishing wheel) replacement cycle 400-500 working hours. If the surface wear exceeds 2mm or is uneven, replace it in time;

- Drainage and sewage disposal: Clean the water tank filter screen (mesh size 200 mesh), discharge the sewage in the water tank (sewage storage ≤5L), and add clean water to the standard liquid level (150-200L); check the water circulation flow rate (≥15L/min) to ensure the 14 grinding heads are fully cooled.

Weekly maintenance (every 5-7 working days, key items)

- Lubrication maintenance (exclusive lubricant and dosage): Add No. 32 mechanical oil to the conveyor belt bearing (dosage: 5-8ml per bearing), 14 grinding head spindles (dosage: 3-5ml per spindle); check the oil level of the centralized lubrication system (standard oil level: 1/2-2/3 of the oil tank), and replenish in time if insufficient; the lubrication cycle of the servo motor reducer is 2000 working hours (lubricant model: N320 gear oil);

- Check electrical components: Inspect the wiring of the power supply, 14 grinding head motors (rated power 1.5kW each), and sensors (positioning accuracy ±0.1mm) for looseness or aging; clean the electrical control box (dust accumulation ≤0.5mm) to avoid dust affecting heat dissipation;

- Adjustment of conveyor belt: Check the tension of the conveyor belt (standard tension: 5-8N/mm), if loose, adjust the tensioning device; the conveyor belt deviation should be controlled within ±0.2mm/m, and the surface flatness error ≤0.1mm/m.

Monthly maintenance (every 20-30 working days, precision calibration)

- Calibrate processing precision (exclusive calibration parameters): Use a level ruler (precision 0.02mm/m) and micrometer to calibrate the flatness of the conveyor belt (error ≤0.1mm/m) and the parallelism of the 14 grinding heads (parallelism error ≤0.1mm); the verticality of each grinding head spindle (perpendicularity error ≤0.05mm/m) should be calibrated, and the fixing bolts should be tightened if there is deviation;

- Inspect core components: Check the wear of the servo motor (noise ≤75dB), reducer (temperature rise ≤40℃), and water pump (head ≥20m); check the sealing performance of the 14 grinding head shafts (no water leakage, pressure resistance ≥0.6MPa); replace worn parts if necessary;

- Overall inspection: Conduct a comprehensive inspection of the equipment, including the integrity of the dust-proof cover, the tightness of the water pipe (no water leakage), and the sensitivity of the emergency stop button (response time ≤0.1s); test the automatic fault alarm function to ensure that the equipment is in a safe and reliable state

The stone processing industry (including marble, granite, quartz stone, artificial stone, etc.) is the most important application field of Edge Grinding Polisher Machine. Stone products such as building facades, floor tiles, tombstone slabs, and steps all need strict edge finishing to ensure quality and safety.

Practical application scenarios and effects:

Large-size stone slab processing: For Large-Size stone slabs used in building facades and large public spaces, the horizontal Edge Grinding Polisher Machine can realize stable conveying without deviation. 

Tombstone and step stone processing: Tombstone edges and step stone edge need precise chamfering and polishing to ensure nice appearance. The Edge Grinding Polisher Machine can accurately process 45° bevels and arc edges with high precision. 

Stone countertop processing: stone kitchen countertops and bathroom vanities need seamless splicing and edge thickening. The Edge Grinding Polisher Machine can grind the splicing surface to a high flatness, ensuring that the thickened edge is smooth and consistent with the overall surface.
