Custom Abrasive Oil Stones and Sticks

Custom Oil Stones & Abrasive Sticks: Precision Solutions for Metalworking

Achieving the perfect finish, precise edge, or exact dimension often comes down to the final steps of grinding, polishing, finishing, or honing. ZYsuperhard doesn’t just supply tools; we provide custom-engineered abrasive solutions designed to meet the rigorous demands of precision industries.

Understanding the different abrasive types is key to selecting the optimal tool for your specific task.

1. Customization is Our Core

We elevate your metalworking precision by offering full customization on all key specifications:

• Materials: A, WA, PA, SA, A/WA, GC, and C models, covering everything from general carbon steel to high-speed steel and complex alloys.
• Grit Sizes: A comprehensive range from 80# (rough grinding) to 1800# (mirror finishing).
• Shapes: Standard squares, triangles, cylinders, and any complex shape required by your specific mold, die, or component geometry.

2. Abrasive Model & Application Guide

Selecting the right abrasive material is critical. Use this guide to match the model to your workpiece material:

Model	Key Features	Primary Applications
A (Brown Alumina)	High hardness and toughness.	Grinding of medium/high tensile strength metals, such as general carbon steel, alloy steel, malleable cast iron, and hard bronze.
WA (White Alumina)	Higher hardness than A, sharp edges, small grinding heat.	Grinding hard and heat-sensitive steel: quenched steel, high carbon steel, and high-speed steel (HSS). Excellent for cutting tools, molds, and gear/thread formation.
PA (Pink Alumina)	High toughness, similar hardness to WA, good angular retention.	Precision grinding of quenching steel, alloy steel tools, and measuring devices. Ideal for forming tools.
SA (Single Crystal Alumina)	Highest hardness and toughness; excellent multi-edge cutting and crushing resistance.	Grinding tough, high-hardness materials like stainless steel and high alum high-speed steel. Essential for preventing workpiece deformation or burning.
A/WA (Mixed)	Combines the advantages of A and WA.	General grinding of ductile iron workpieces, such as shafts and wheel axles.
GC (Green Silicon Carbide)	High hardness, brittleness, sharp abrasive, good thermal conductivity.	Grinding complex alloy tools and workpieces; also suitable for non-ferrous metals and non-metallic materials.
C (Black Silicon Carbide)	High hardness, brittle, sharp abrasive, specific thermal conductivity.	Grinding non-metallic materials and non-ferrous metals.
