It can be repaired, and the precision of the granite platform (marble platform) can be restored through professional grinding, which is a very routine operation in the industry.
I. Is it repairable?
In the vast majority of cases, repair is possible.
Unless:
The entire piece is fractured or has severe chipping
The internal structure is cracked or deformed
The thickness is worn too thin, losing rigidity
General flatness deviations, scratches, pits, and local high point be restored to precision through re-grinding.
II. What precision can be achieved after repair?
After repair, it is usually possible to restore to:
Grade00, Grade 0, Grade 1
This specifically depends on:
The original platform thickness and dimensions
The extent of damage
The grinding process and equipment
After repair, the flatness of larlatforms can fully meet the standards of new factory parts.
III. Repair Methods (Professional Process)
Cleaning and Inspection
Inspect flatness using levels, optical flats, and laser interferometmarking high and low points.
Rough Grinding
Use diamond abrasives with standard grinding plates to remove high points and scratches.
Fine Grinding
Use fine-grained micro-powders ually refine the surface, achieving the required flatness.
Scraping / Fine Adjustment
Make micro-adjustments for local minute deviations to finally reach graded precision.
Issue Inspection Reportire process is physical grinding; no chemical corrosion is used, and it is harmless to the stone itself.
IV. Situations where repair is not recommended
The platform is already severely tered or delaminated
The size is very small, the inherent value is low, and the repair cost is close to buying a new one
The thickness is too thin; further grwould affect rigidity and stability
V. Simple Judgment Suggestions
Just precision loss, scratches, or minor bumps: Strongly recommended for repair; high cost-effectiveness
Large-scale chipping or fractures: Replace directly.
