Whether you have a honed or flat surface, the process of sharpening a wood processor carbide saw blade is quite similar to sharpening a standard blade. The first step to sharpening these saw blades is to remove any loose teeth or burrs. The next step is to grind the surface to a mirror-like finish, which should leave them very sharp. Once the blade has been sharpened to the desired level, you should inspect it one last time for any damage.
Hollow face grinding
Hollow face grinding is a specialty process that is done on wood processor carbide saw blades to produce a smoother, sharper cut. These blades can be used on a sliding or vertical saw. They are excellent for finishing double-sided laminated panels without scoring them. However, they must undergo special sharpening procedures. This includes face grinding on each re-grind.
CHP machines are designed for saw mills, solid wood, and furniture-producing sectors. Their hydraulic lift system, wide-opening blade clamping mechanism, and diagonally integrated feed pawls make them ideal for this task. They also can process saws with reinforcement rings or collars. The CHP machines incorporate variable-speed motors that help optimize the process.
The CHP series of grinding machines are perfect for the sharpening of carbide-tipped circular saw blades. The CHP 840 series includes four CNC-controlled axes and can sharpen TCT saw blades up to 1300mm. This high-performance machine is also designed to grind angled radii in the face of the blade and can sharpen all tooth geometries within a single cycle.
A high-speed steel blade is available with a slitting function. These blades can cut through tubes that have wall thicknesses of 2mm to 10mm. In addition, the slitting saws have tooth forms of “A”, “BW”, and “BW”. They are also readily available in a PVD-coated or VAPO coating.
The Cobalt content in wood processor carbide saw blades is an important factor to consider when purchasing a saw blade for your cutting applications. It affects the hardness, impact toughness, and wear resistance of the blade. These characteristics help determine the durability of the blade and reduce the need to replace them frequently.
Cobalt-based alloy cutting tips can be produced in a variety of ways, including powder, liquid phase, or solid-state sintered methods. These cutting tips are then coupled to the saw body through welding, brazing, or resistance welding. Cobalt-based alloy cutting tips can also be provided in rod or wire form.
The Cobalt content in wood processor carbide saw blades varies between grades. Some are higher in Cobalt than others, while others have lower levels of this metal. Typically, wood processor carbide saw blades are in the YG8 to YG15 grade range. The YG code indicates the percentage of cobalt present in the alloy. The higher the content, the more the alloy will be hard and less brittle.
A cobalt-based alloy will have cutting tips formulated specifically for a specific microstructural phase, such as tungsten or chromium carbide phases. The alloy may also contain other elements to stabilize the cubic crystalline structure of cobalt. These elements may include nickel, vanadium, carbon, or other elements.
Researchers studied wood processor carbide saw blades to determine whether cobalt content can affect worker health in the workplace. They also evaluated the amount of cobalt in grinding coolants. The new coolant used to replace the old coolant decreased airborne cobalt concentrations, but did not affect urinary cobalt levels.
Choosing a circular saw blade
Before sharpening your saw blade, you need to cut off the tooth that is most worn out. To do this, use a sharpening file with a 20-degree tilt. You should hold the saw blade in the vice without over-tightening it. The blade should have sharp teeth when you are done sharpening it. Remember to file the opposite side of the blade as well.
A carbide tipped saw blade is great for cutting composite materials like hard glue and resins. It also gives you a good metal removal rate. Compared to high-speed steel blades, carbide saw blades are highly durable and can be sharpened and re-sharpened for years without losing their edge.
Generally, a saw blade should have 60-96 teeth. This size is suitable for cross-cutting solid wood and also for cutting MDF or plastic. For wood-based materials, a saw blade with a dovetail tooth pattern is best. Depending on the material being sawn, you may need to use a different saw blade.
If you use a circular saw, you should regularly sharpen it. Otherwise, the teeth can be blunted, causing the saw blade to make incorrect cuts. These mistakes can cause serious damage to the saw and the blade. LEUCO offers expert circular saw blade sharpening services.
It is also important to sharpen the blade on firewood processors. A sharp blade will help you to cut firewood efficiently. The sharp blade will also reduce the amount of sawdust that will be created. In addition, a sharp saw blade is easy to use.
Choosing a sharpening machine
There are several factors to consider when choosing a sharpening machine to sharpen a wood processor carbide saw blade. First of all, it is essential to ensure that the teeth on the blade are sharpened on all four sides. The surface of each tooth is ground from different angles, and one or two teeth offset from the rest will have a dramatic effect on the performance of the blade.
After sharpening, the blades must be cleaned thoroughly and examined for flatness. A blade with buildup will not perform optimally, and it will also increase the possibility of damage to the saw blade and equipment. Furthermore, a blade with buildup will not cut straight.
The blade should be stored on a cushion, which protects the tooth surface. It should be sharpened using diamond grinding wheels, which are suitable for sharpening carbide saw blades. The blade should also be carefully checked for defects, such as irregular vibrations.
Another important factor to consider when choosing a sharpening machine is the sharpening wheel. The grinding wheel used should have a bonded metal bond, which has good wear resistance and long service life. It should also have a fixed angle.
The machine should be easy to use and have high-quality features. It should also have a strong indexing arm, so you can adjust the blade at a faster pace. The machine should also have high-speed RPM to make the process faster. A turntable is also necessary for easy blade adjustments.
While it may seem simple enough to perform the job yourself, it is important to note that sharpening wood processor carbide saw blades requires precision and experience. If done incorrectly, you could damage the blade permanently. Luckily, there are several sharpening machines to choose from.
Choosing a Leitz blade
In wood processing, choosing the right blade is important to ensure the smoothest cut possible. A thin kerf and smooth finish are key in maximising yield and avoiding expensive 2nd operations. Fortunately, Leitz offers a wide range of carbide-tipped circular sawblades to meet your needs.
Noise levels in the woodworking industry are getting louder by the day, and this is largely due to the tools used in processing wood. Circular saws, for example, are notorious for generating high amounts of noise. The constant spin of the blade creates a loud roar, which can be uncomfortable for operators and annoying for co-workers.
Circular HW saw blades are designed to be used on single and double spindles, and are suitable for cutting hardwoods and softwood. They are also a good choice for high-speed cutting and are ideal for slicing plywood, sheet metal, and wood.
After cutting the workpiece to size, the first step is pre-planing. This prepares the surface for the subsequent processing steps. It also creates a datum surface for a more accurate cut. Pre-planing is particularly important before profiling on four-sided moulders. For profiling applications, pre-planing and reference heads can be used on the same spindle.
