How to grind veneer peeling lathe knife

Grinding a veneer peeling lathe knife requires careful attention and the use of specialized tools. Here is a detailed explanation of the equipment and steps involved in grinding a veneer peeling lathe knife.

Equipment Needed:

Grinding Wheel: A high-quality grinding wheel specifically designed for sharpening knives is essential. It should have a grit suitable for the initial rough grinding and a finer grit for achieving a sharp edge.

Bench Grinder: A bench grinder with adjustable speed is recommended for precision grinding. The grinder should be securely mounted to a sturdy workbench or stand.

Honing Stone: A honing stone or sharpening stone is used for refining and polishing the edge of the knife after the initial grinding. It helps achieve a razor-sharp edge.

Safety Equipment: It is crucial to wear safety goggles, gloves, and a face mask to protect yourself from flying debris and metal particles.

Grinding Process:

Preparation: Ensure the grinding wheel is clean and in good condition. If necessary, dress the wheel to remove any debris or unevenness.

Adjust the speed of the bench grinder to a suitable level for grinding. Higher speeds may generate excessive heat and damage the blade.

Secure the Knife: Use a knife holder or a secure vise to hold the knife firmly during the grinding process. This ensures stability and safety.

Rough Grinding: Start by grinding the beveled side of the knife. Hold the knife against the grinding wheel at the desired angle, typically around 25 to 30 degrees.

Move the knife back and forth across the grinding wheel, maintaining a steady and consistent pressure. Ensure even contact with the wheel to prevent uneven grinding.

Avoid applying excessive pressure, as it can lead to overheating and damage the knife. Frequently dip the knife into water to cool it down during the grinding process.

Fine Grinding: After the rough grinding, switch to a finer grit wheel or adjust the grinder for a lighter touch.

Repeat the grinding process, ensuring a smooth and even removal of material. This step helps refine the edge and improve sharpness.

Again, remember to cool the knife in water periodically to prevent overheating.

Honing: Once you are satisfied with the sharpness achieved through grinding, proceed to hone the edge using a sharpening stone.

Wet the honing stone with water or honing oil and hold the knife at the desired angle against the stone.

Move the knife in a slicing motion along the stone, applying light pressure. Repeat this process on both sides of the blade until a fine edge is achieved.


Carefully examine the knife under good lighting to ensure the edge is sharp and free from any imperfections or burrs. Make any necessary adjustments using the honing stone.

Grinding a veneer peeling lathe knife requires skill and practice. If you are uncertain or inexperienced, it is advisable to seek guidance from an experienced professional to ensure optimal results and safety.
