What Is The Service Life Of Resin-bond Diamond Frankfurt Abrasive Blocks?

What is the service life of resin-bonded diamond Frankfurt abrasive blocks?

Before examining the service life of Resin Frankfurt abrasive blocks, we first establish a standard.
Testing standards:

1. Test equipment: T105 standard automatic "Frankfurt-type" polishing line
2. Product specifications: 40mm standard abrasive layer
3. Material processed: 20mm standard large marble slab
4. Other operating conditions: Adequate circulating cooling water, standard grinding head pressure

Comprehensive data on the service life of resin-bonded diamond Frankfurt abrasive blocks

  I. Standard processing area by grit size (per piece, m²)  
1. Medium polishing grits #120 – #600

Tips: high material removal, faster wear
Standard resin type: 18,000–24,000 m²/piece
Upgraded aging-resistant resin type: 21,000–28,000 m²/piece

2. Fine polishing / mirror-finish grits #800 – #3000 / Buff

Tips: low material removal, longer life

• Standard resin type: 22,000–30,000 m²/piece
• Upgraded aging-resistant resin type: 26,000–36,000 m²/piece

  II. Impact of different stone types on service life  

• Standard beige or light gray marble: Baseline figures above
• Hard marble, terrazzo, epoxy-repaired slabs: Service life reduced by 20%–30% (14,400–25,500 m²)
• Soft/elastic resin for Onyx: Service life 10%–18% shorter than general-purpose hard resin

  III. Summary of the impact of operating conditions on service life  

1. Water shortage or insufficient flow:Resin pulverizes due to high heat;
2. Service life is immediately cut in half 24-hour continuous production: Service life reduced by approximately 15%;
3. Excessive grinding head pressure or excessive slab feed speed: Wear rate increases by over 25%;
4. Thickened abrasive layer (45/50mm): Overall service life increases by 18%–25%.
