What is the service life of metal-bond diamond Frankfurt Abrasive blocks?
The service life of metal-bond Diamond Frankfurt Abrasive blocks varies depending on the type of stone slab, diamond grit size, operating conditions, and the specific machinery used.
Here is a brief overview of the service life of these blocks, based on standard specifications.
Service life specifications for metal-bond diamond Frankfurt Abrasive blocks (T105 Frankfurt/ Horseshoe style):
Test parameters:
- Standard 40mm abrasive layer;
- 20mm standard large marble slab;
- fully automatic polishing line; adequate circulating water cooling;
- standard grinding head pressure.

I. Processing Area per Segment (m²/piece) by Grit Size
1. Extra-coarse grits #24 / #36 / #46
High material removal rate; removes deep saw marks from raw blocks; fastest wear rate
- Standard metal formula: 35,000–45,000 m²/pc
- Cheefung factory's high-cobalt, wear-resistant formula: 40,000–48,000 m²/pc
2. Mainstream medium-coarse grits #60 / #80 / #120
Highest usage volume on production lines; primary choice for slab leveling
- Standard metal formula: 38,000–48,000 m²/pc
- Improved wear-resistant formula: 43,000–52,000 m²/pc
3. Transitional coarse grinding #180 / #240 / #320
Final stage of coarse grinding; refines deep surface marks
- Standard metal formula: 42,000–50,000 m²/pc
- Improved wear-resistant formula: 47,000–55,000 m²/pc
After cheefung company's improvement, the metal bond Diamond Frankfurt Abrasive block has better sharpness and does not damage the surface of the stone slabs.
II. Impact of Stone Hardness on Lifespan
- Standard beige or light gray marble: Lifespan remains stable at the baseline figures above.
- Hard marble, epoxy-repaired slabs, and terrazzo: Lifespan decreases by 15%–25%.
- Soft Onyx: Not recommended; forced processing doubles the wear rate and risks scratching the stone surface.
III. Four Key Factors Affecting Operating Condition s
1 Cooling water supply
Insufficient or interrupted water flow causes the metal matrix to overheat and wear rapidly, reducing lifespan by over 40%; for high-speed production lines, diagonal water-cooling slot designs are preferred for stable heat dissipation and extended service life.
2 Head pressure and conveyor belt speed
Excessive pressure or overly fast slab feed speeds cause a sharp increase in cutting load, raising the wear rate by more than 25%.
3 24-Hour Continuous Production vs. 8-Hour Intermittent Production
Continuous round-the-clock processing leads to sustained heat buildup, reducing lifespan by 15%; intermittent production offers more stable longevity.
4 Abrasive Layer Thickness
Based on a standard 40mm thickness; thickened wear layers of 45mm or 50mm extend overall service life by 18%–25%.
IV. Comparative Lifespan Analysis of Three Types of Frankfurt Abrasive Blocks
Based on #60 Grit
| Product Type | Processing Area per Piece | Relative Lifespan (Multiple) |
| Metal-Bond Diamond Frankfurt Abrasive | 35,000–52,000 m² | Baseline (1x) |
| Resin-Bond Diamond Frankfurt Abrasive | 18,000–30,000 m² | Approx. 0.5x |
| Magnesite Horseshoe Frankfurt Abrasive | 1,200–3,500 m² | Only 1/15–1/20 |
