The veneer knife represents the maximum maintenance cost of the paper cut, so it is worth using good sizing specifications and paying attention to grinding and setting the tool in a lathe or slicer.
What should I say when ordering a knife for a lathe or slicer? The length of the knife and the presence or absence of the grooves and their spacing will be determined by the equipment using the knife. Others can specify factors such as depth, thickness, hardness, inserts or solids, and grinding. In addition, carbon and other components of the percentage of steel can be specified. But the exact part of the knife. Steel is generally not published by tool manufacturers. As a result, most plywood factory managers deal with a reputable tool manufacturer, specifying only size, shape, hardness, and the need for a blade or solid blade. The ideal tool should have the greatest stiffness, toughness, corrosion resistance and wear resistance.
The hardwood veneer is usually cut with a mosaic knife. Low-carbon steel for backing is stable and easy to wear. Can be easily drilled, so that in the post-grinding can be firmly fixed knife. Highly refined hardened tool steel blades usually have the highest quality of cutting wood. It is reported that hardened tools can stand better when cutting induration. Sometimes but not always used to produce architectural plywood.
Most veneer knives are the full length of the lathe or slicer supply. However, sometimes using a three-piece knife with a special clamping device can be grounded and set to a unit. If a component is damaged, the entire tool can be replaced.
Should specify the hardness of the tool, and can be easily tested. A soft knife can be easily hone, very hard, but also quickly wear. A hard knife is difficult to hone, if playing hard disk, then may be better, but the edge of the sharp is much better. Most rotary plywood is preferably a knife with a Rockwell hardness of 56 to 58 ° C scale. For single-sided plywood slicers, the Rockwell C scale is typically 58 to 60. In order to keep the edge as sharp as possible when cutting low density wood, you can even use a knife with a Rockwell hardness of 60 to 62.
