Garnet 80# for Stone Waterjet Cutting
1. Basic Physical & Chemical Specifications
- Garnet Grit Size: 80 mesh, particle size: 0.15–0.355 mm
- Hardness: Mohs hardness 7.5–8.0, excellent self-sharpening property; continuously forms sharp edges after fracture for powerful cutting performance
- Specific Gravity: 4.1–4.2 g/cm³, fast sedimentation, low risk of sand pipe clogging
- Appearance: Reddish-brown particles; premium grade purity ≥95%, low dust content, minimal fine particles, no oversized grains
- Matching Focus Tubes: Standard fit for 0.762 mm, 1.02 mm, 1.27 mm focus tubes, compatible with most stone waterjet cutters
2. Core Advantages for Stone Cutting (Industry Standard 80# Grade)
- Optimized balance between cutting speed & precision
- Compared with 60#: Slightly slower cutting speed, straighter cut edge, smaller taper angle and smoother cutting surface, no secondary polishing required
- Compared with 120#: Higher cutting efficiency for thick stone mass production with better cost performance
Compatible with most stone materials
Granite, marble, sintered stone, quartz stone, ceramic tile, slate, bluestone, artificial stone, stone mosaic pattern cutting, tombstone engraving, countertop hole drilling & arc cutting
Also applicable for cutting stainless steel, aluminum plate, ceramics, glass, etc.
Low nozzle clogging rate & reduced consumable wear
Concentrated particle size distribution, low fine powder content, preventing sand nozzle & focusing tube blockage during long-term continuous cutting of thick plates; free of free silica, eco-friendly and compliant with environmental regulations
3. Grit Selection Comparison (Common Grades for Stone Factories)
| Grade | Characteristics | Stone Application Scenarios |
|---|---|---|
| 60# | Coarser grains, fastest cutting speed, relatively rough cutting surface, wider kerf | Rough cutting for extra-thick stone, blanking with low surface finish requirements |
| 80# | Best balance of cutting speed & surface smoothness, most versatile grade | Conventional cutting, mosaic processing & countertop fabrication for most stones (top mainstream choice) |
| 120# | Fine & smooth cut surface, narrow kerf, slower cutting speed | Precision cutting for thin plates, mirror finish for high-end stone, intricate small pattern machining |
4. Operation Guidelines
- Packaging: 25 kg woven bag / 1 MT jumbo bag; store in dry condition, dampness causes agglomeration and sand line blockage
- Grade Classification
- Premium / Import Grade: Ultra-low dust, sharp angular grains, high cutting efficiency, ideal for high-end sintered stone & premium stone processing
- Regular Grade: Cost-effective, suitable for mass rough machining & blanking of ordinary marble & granite
