Grinding Wheels For Sharpening Woodturning Tools

8 inch high performance wood turning tools grinding wheel There are many types of tool materials. The common materials are mainly divided into four categories: tool steel (including carbon tool steel, alloy tool steel, high speed steel), cemented carbide, ceramic tools and superhard tool...

  • Features & Specification

    Woodworking turning tools are used for cutting wood or wood composites, which are differ from metal materials. Its hardness is much harder than metal. Woodworking tools should be maintained sharp cutting performance over long periods of time under high-speed and impact-bearing cutting conditions. Woodworking tool materials also must have the necessary hardness and wear resistance, sufficient strength and toughness, and certain processability (such as welding, heat treatment, cutting and grinding performance). At present, the materials of woodworking tools are carbon tool steel (carbon steel), alloy tool steel (joint steel, high speed steel, hard alloy, tungsten, etc.


    Regular diameter: 6 inch, 7 inch, 8inch 


    Why is CBN grinding wheels? 

    1, high temperature resistance, good thermal stability

    Cubic boron nitride can withstand high temperatures of 1250-1350 degrees Celsius, which is higher than the diamonds of 800 degrees Celsius. When grinding and cutting iron materials, there will be no sticking phenomenon. For grinding hardened steel, high vanadium high speed metal materials, aluminum high-speed steel that are sensitive to grinding temperatures, CBN wheels are the most ideal tools.

    2, strong chemical inertia

    Cubic boron nitride is not easy to react with iron group elements, so it is suitable for grinding the materials, like high speed steel, tool steel, die steel, high alloy hardened steel, chrome steel, nickel alloy, powder metallurgy steel and high temperature alloy.

    3, good thermal conductivity

    The thermal conductivity of CBN can reach 10 to 100 times that of corundum grinding wheel, so the grinding heat can be quickly exported and reduce the workpiece deformed. It is very suitable for grinding materials with low thermal conductivity, such as various spraying (welding) materials: nickel base, iron base; wear-resistant cast iron materials: vanadium-titanium cast iron, high-phosphorus cast iron, chilled cast iron; titanium alloys etc.

    Mature technology, mass production 

     Aluminum base 


    Steel base 



    1. What is wheel dressing?

    Unlike resin bond, vitrified bond and metal bond grinding wheels, electroplated cbn grinding wheel is no need dressing. It is only coated a layer of CBN abrasive on the wheel, there is also no need coolant when working.

    2. Wha’s the regular size of cbn wheels for woodturners?

    For most of cbn sharpening wheels, 8 inch 5 8 arbor grinding wheel is the most popular one, the arbor also can be 1/2inch and 3/4inch or customized. We also make 6 inch grinding wheel 1 2 inch arbor and 7 grinding wheel 5 8 arbor.

    3. How to sharpen lathe tools by hand?

    When sharpening, the cutting edge of turning tools is gently pressed against the end surface of the grinding wheel. And then cutting tools should move slowly to the left and right, so that the grinding wheel wears evenly and the cutting edge is straight and smooth.
