What is the best grinding wheel for tool steel?

Aluminium Oxide Generally recommended for grinding materials of high tensile strength, such as stainless steel and tool steels but it can also be used on some high tensile aluminium and bronze alloys.

What is a CBN wheel?

What is a CBN Grinding Wheel? A CBN wheel is made from cubic boron nitride. This material is one of the hardest materials available, second only to diamonds. The main feature of the material is that it features a high abrasion resistance and thermal conductivity that maintains its sharp cutting edges.

What Grit is a general purpose grinding wheel?

Grinding wheels usually will be between 24 and 100 grit. Honing stones and jointing stones and other polishing abrasives will be 150 grit and higher. Use a coarse grit for fast, aggressive stock removal and finer grits for less stock removal but better surface finish.

How do I choose a grinding wheel?

After the abrasive material and wheel shape, main factors for wheel selection are grit size, bond type and bond hardness. Workpiece material dictates the abrasive, wheel shape and type of bond. Grit size and bond hardness usually are chosen based on surface finish requirements and the hardness of material.

What side of the grinding wheel should be used to grind objects?

Grind evenly across the face, avoid creating ruts in the wheel. Do not use the side of a grinding wheel, just the face. Side pressure can cause a wheel to crack. Do not grind too hard, do not try and take off too much material too fast, use the right tool for the right job.

What are green grinding wheels used for?

Green Silicon Carbide for non-ferrous metals, tungsten carbide for sharpening carbide tools in tool rooms. Type 1 – Straight vitrified wheels used for tool sharpening and grinding. Commonly used in maintenance departments, tool & die shops and metal fabrication shops.

How do I know what grinding wheel I have?

The size of the grinding wheel is marked as dimensions in mm. For example, 230 x 3 x 22.2mm. This represents the wheel’s diameter x thickness x hole size.
