Sources Once you have a good solid grinder, you will want to put good belts on them. I will go over the different types of belts below: 4 types of abrasive belts: To grind steel with abrasive belts, you need high belt speed and the ability to exert high pressure. Your motor has to keep up! The Larger the motor, the more powerful the grinder. A rule of thumb is you need 1 horsepower (hp) of motor power per 1” of belt width for a 72” long belt. Notching tubes with thinner walls, such as handrails, requires a less aggressive belt. Here, we would recommend the 60 grit Ceramic FX87 belt (SKU: FX87/60/2000X75). The cooler and faster cut of the Ceramic belt again offers a consistent notch. Additionally, using a 60 grit belt leaves finer sanding marks than a 36 grit belt, allowing for a neater, cleaner weld – one that uses less welding wire.

Drive Wheels for Beltits

For example, a 2x72 grinder runs best with a motor of 2hp.. But a 1x72”: grinder would grind great with only 1hp. When you reduce your belt length, you also reduce the demand on the motor which is why our 2x48” machines are supplied with a 1.5hp motor. A range of self adhesive platen pads are available to enable the operator to achieve their best work from their Beltit. Seco's platen pads are interchangeable with several tools available on the international market, including Dynabrade and ATA tools. All of Seco's spare parts are competitively priced and readily available. Notching aluminium tubes? Particularly on thin wall tubes the softer metal calls for a finer belt. Ceramic FX87 Belt in 80 grit (SKU: FX87/80/2000X75) will leave a consistent notch which will weld easily. FF87 is our more flexible ceramic abrasive sanding belt. We particularly recommend the FF87 belts for finer sanding with powerfile machines and also with tube polishers. Built-into this device is an adjustable eye shield to add an extra layer of protection against shrapnel. Unfortunately, it’s only for the grinder. But since this has a true grinding wheel rather than the sanding wheel on most belt grinders, you’ll be able to use it as a round grinding surface when making knives.

The power of a motor is measured by horsepower. Depending on the volume and intensity of the knife-making work, different levels of power may be necessary. Surface grinding attachments like a sanding disc, are also very common on a grinder for knife making. Some machines have a pre-installed disc while others have an arm to add these sanding or buffing attachments. The Palmgren belt and disc finishing machine is a great starter machine for new knife makers. It includes a belt for beveling and even a disc sander for flattening the knife blade. The machine is “easy to use,” as one user stated. Another customer found that it is very simple “to change out the belts, provided you leave off the belt guards.”

Zircuonium can handle steel better than aluminum oxide belts, but they wear out faster than ceramic belts. The robust motor brings 2 horsepower and works smoothly to ensure a stable and quiet use. Owing to an all-steel structure, the belt grinder is always solid and sturdy enough for you to do any knife making, woodworking or tool polishing. Compared to some hobbies, knife making has a pretty low barrier to entry. All it takes to make a knife with modern equipment is a little instruction from YouTube, some steel, a few other basic materials, and a belt grinder. But the belt grinder is really the crux of everything since it will allow you to shape and form your knife.

Same brand as before, they make good high grit AO belts. Best Aluminum oxide 400 grit belt for knives The speed at which your belt travels is the third key component to grinding steel. It needs to move significantly faster than a wood-sander to grind optimally. The 2x48” machines in our shop run at 4100 surface feet per minute (sfpm). FX87 36 grit ceramic 75 x 2000mm grinding belts. More expensive than the 36 grit zirconia belts the 36 grit ceramics earn their keep being much longer lasting and fast cutting making them the most cost effective high aggression grinding belt option.The most popular sanding belts for wood are made from our KP949 materials and are often supplied for both long pad sander sanding belt machines and for wide belt sander applications. We supply a wide range of sanding belts for metals. The Cibo Ceramic belts are particularly suited to aggressive sanding & grinding. Ceramic grains are tougher and more durable than zirconia so the more aggressive the application, the greater the potential benefit As the price difference in a file belt is small it is not a cost effective solution for the end user.
