Applications of Bowl-Shaped Grinding Wheels
Thanks to their unique shape, bowl-shaped grinding wheels are widely used for grinding, edge sharpening, and polishing on various materials. Depending on the target application, their main uses include:
1. Tool Edge Sharpening
One of the core uses of bowl-shaped grinding wheels is edge sharpening. They are particularly suitable for grinding various hard alloy and high-speed steel tools, such as turning tools, milling cutters, and drill bits. Their shape makes it easier to control the grinding angle.
2. Molds and Metal Processing
In mold manufacturing and metal parts processing, bowl-shaped wheels play an important role. They can be used for precision mold finishing, model trimming, fine grinding and polishing of metal components, as well as smooth grinding, chamfering, and deburring of metals.
3. Hard and Brittle Material Processing
Bowl-shaped wheels are ideal for processing high-hardness and difficult-to-machine materials. This includes glass (e.g., smartphone panels), ceramics, gemstones, quartz, as well as stone and concrete grinding.
4. Other Specialized Applications
In certain industrial production lines, bowl-shaped grinding wheels are used for heavy-duty grooving, grinding ceramic valve balls, and grinding hard alloys such as tungsten carbide.
The wide application of bowl-shaped grinding wheels is due to their working surfaces, which include the bottom, end, and inner circular surfaces. This makes them especially suitable for applications requiring precise control of workpiece angles and shapes.
According to different raw materials, bowl shaped grinding wheels are available in the following types:
-
White Aluminum Oxide (White Corundum)
-
Brown Aluminum Oxide (Brown Corundum)
-
Green Silicon Carbide
-
Pink Aluminum Oxide (Chrome Corundum)
White Aluminum Oxide Bowl Wheels
White aluminum oxide bowl-shaped grinding wheels have good toughness and are suitable for materials such as 45 steel, high-speed steel, and alloy steel. They are ideal for grinding harder steels and heat-sensitive metals, offering long service life and high grinding efficiency.
Brown Aluminum Oxide Bowl Wheels
Brown aluminum oxide bowl wheels have high hardness and toughness. They are suitable for cast iron and iron parts, as well as medium-to-high tensile strength metals such as carbon steel, alloy steel, malleable cast iron, and hard bronze.
Green Silicon Carbide Bowl Wheels
Green silicon carbide bowl wheels are very hard and brittle, providing sharp grinding with good heat conductivity. They are suitable for tungsten carbide, alloy steel, alloy cutting tools, workpieces, non-ferrous metals, and non-metallic materials.
Pink Aluminum Oxide Bowl Wheels
Chromium corundum bowl wheels have a hardness of around 58 and are suitable for hardened steel components. The abrasive grains are sharp, edges remain well-defined, and the wheels are durable. They are tougher than white aluminum oxide wheels and are ideal for precision grinding of hardened steel, alloy cutting tools, workpieces, measuring instruments, and parts. They are also suitable for form grinding.
