Product Description

120 Mesh Waterjet Cutting Abrasive

SGA 120 Waterjet Garnet for Fine Waterjet Cutting

SGA 120 is a fine alluvial pink garnet abrasive for precision waterjet cutting. Compared with standard 80 mesh garnet, 120 mesh is finer and is better suited for thinner materials, softer materials and jobs requiring smoother edges, tighter accuracy and cleaner surface finish.

What Is SGA 120 Waterjet Garnet?

SGA 120 is produced from alluvial pink garnet through washing, separation, drying and precision screening. Its finer particle size helps produce smoother cutting surfaces and supports more accurate forming for thin metal, glass, ceramic, stone and other precision cutting applications.

120 Mesh Grade Fine abrasive size for precision waterjet cutting.

Smoother Cutting Edge Helps create cleaner edges on fine cutting work.

Stable Abrasive Flow Uniform particle distribution helps reduce feed blockage.

Lower Equipment Wear Fine, consistent grains help protect cutting heads and focusing tubes.

Low Chloride Content Supports cleaner cutting for metal surfaces.

Bulk Export Packaging 25kg bags and 1000kg jumbo bags are available.

Typical Waterjet Cutting Applications

120 mesh waterjet garnet is used when cutting quality and surface finish are more important than aggressive cutting speed. It is suitable for fine cutting of thinner metal, glass, ceramics, stone, rubber, soft materials and detailed forming work.

Waterjet cutting stainless steel with garnet abrasive

Fine Metal Cutting

For thinner stainless steel, aluminum and metal parts where smoother edges and tighter accuracy are required.

Waterjet cutting stone glass and ceramics with garnet abrasive

Glass, Ceramic and Soft Material Cutting

For glass, ceramics, stone, rubber and softer materials needing a fine abrasive and cleaner cut surface.

Production Process

SEPPE processes alluvial garnet through washing, desliming, gravity separation, drying, magnetic separation and precision screening to control oversized particles and produce a finer 120 mesh grade for stable precision cutting.

Garnet Processing and Classification

Laboratory Testing & Quality Control

For waterjet cutting, particle size distribution, moisture, bulk density and chloride content directly affect abrasive flow, cutting stability and nozzle service life. SEPPE checks each batch before shipment.

Particle Size Verification Helps reduce oversized particles and feed blockage.

Moisture Control Supports free-flowing abrasive in waterjet systems.

Low Chloride Content Helps minimize rust risk on cut metal surfaces.

FAQ

?What is 120 mesh waterjet garnet mainly used for?

120 mesh garnet is mainly used for fine waterjet cutting where smoother edges, tighter accuracy and cleaner surface finish are required.

?What is the difference between 80 mesh and 120 mesh?

80 mesh is a common general cutting grade. 120 mesh is finer and is often selected for thinner, softer or more delicate materials that need a smoother cutting surface.

?Is 120 mesh suitable for thick metal cutting?

For thick metal and common production cutting, 80 mesh is usually the standard choice. 120 mesh is better when fine edge quality and precision are more important.

?Can I test SGA 120 before bulk order?

Yes. Samples and technical documents can be arranged so buyers can test cutting quality, abrasive feed and consumption before bulk purchasing.
