Diamond Tools Information: Diamond Blade Safety

Diamond Blade cutting information

Diamond tools or any other power tools can be potentially dangerous if not used correctly. This article will touch base on a few of the do's and don'ts of general diamond saw blade usage.

Things you should check before you begin cutting.

(Always wear proper safety equipment)

1. Make sure the diamond blade has no damage to it (shipping or previous use) before mounting on your saw.

2. Make sure the arrow indicates the correct rotation direction when mounting on the saw, if you put a diamond blade on backwards the efficiency will be greatly reduced and you will not get the full life out of the saw blade.

3. Tighten the flanges (plates that hold the diamond blade on the crank shaft) to avoid the blade from slipping during the cut and to ensure full cutting performance.

4. If you are using a wet cutting saw, make sure the waterways are clean and unobstructed to prevent overheating of the diamond blade and to clear the cut of any slurry. (cutting material left behind during the cutting process)

5. Make sure you know the correct RPM speed of the blade and use the saw accordingly.

6. Wear respiratory safety gear to avoid breathing any potentially hazardrous air born dust cause by cutting. (Even when wet cutting, it is always recommended to wear all the proper safety equipment)

7. Make sure the diamond blade still has cutting segments! All diamond blades have a welding line, whether it be laser welded or sintered there is always about 1mm of useless segments. Check your diamond blade periodically when you notice the segments are nearly worn. By cutting with useless segments you can damage your cutting saw.

Tips to ensure correct cutting procedures.

1. Make sure your saw has proper maintennance: Check the flanges, crank shaft (arbor), bearings, belts, filters, oil, etc.

2. Make sure your cutting saw's arbor shaft spins on a true axis. A shaft than has any type of wobbling will greatly reduce the life of your diamond tool.

3. Use light to medium pressure when cutting, allow the diamond blade to push through the material at a safe speed.

4. Never apply excessive pressure or you may overheat the diamond blade or worse yet, throw a segment which can be potentially fatal considering the RPMs at which the saw runs.

5. Make sure your time blade has enough diamonds protruding on the surface or it will not cut effectively. Common cause of this is cutting a material that is too hard for the diamond blade's bond. You can cut highly abrasive materials to resharpen the diamond blade, such as asphalt or abrasive cinderblock.

6. Make shallow cuts in the material you are cutting. For example, if you need to cut 4 inches deep you should cut in 2 passes. The 1st pass at 2" deep and the second pass at the full 4" depth to avoid overheating and extend the diamond blade's life duration significantly.

7. Never use a diamond blade for grinding materials. A diamond blade should ONLY be used to make straight cuts, if you try to cut in curves it is very likely that the diamond blade will get stuck or break a segment and send it flying at dangerous speeds. At the very least, the blade will wear unevenly and overheat (since the diamond segments lose their width they also lose their potential to retain heat, thinner objects overheat much faster)

8. Make sure the diamond blades is not bent, this is a hazard since it could get caught in the cut and throw segments.

9. Never stand in front of the saw, it can send the cutting material forth at high speeds and potentially cause injury.

10. Use the diamond blade only on materials it is specifically manufactured for. Using the wrong diamond blade on specific materials can cause segment loss, smoothing of the segments (causing it to cut very slow and ineffective), extremely fast wear or not cut at all.

If you follow these simple steps you'll save time and money through the effective use of diamond blades and save yourself lots of grief or possibly injury in worst case scenarios

Thanks for reading, good luck on your upcoming cutting projects!

Asphalt (Bitumen) $30 Asphalt more commonly referred to as bitumen in Europe is a dark brown to black cement-like semisolid or solid or viscous liquid produced by the non-destructive distillation of crude oil during petroleum refining. The major types of asphalt products are paving asphalts and roofing asphalts. Asphalt is also used in asphalt-based paints as protective coatings to prevent corrosion of metals; in lining irrigation canals water reservoirs dams and sea defence works; in adhesives in electrical laminates; and as a base for synthetic turf. The exact chemical composition of asphalt is dependent on the chemical complexity of the original crude petroleum and the manufacturing process. Crude petroleum consists mainly of aliphatic compounds cyclic alkanes aromatic hydrocarbons polycyclic aromatic compounds (PACs) and metals (e.g. iron nickel and vanadium). This book evaluates the effects of asphalts on human health and environment. The frequency and concentration of potential asphalt exposures may be lower for the general population than for workers in the various sectors of the asphalt industry. Acute effects of exposure to asphalt vapours are reported.

Polymers in Asphalt $140.12 This review explores some of the detail behind the type of polymers used in asphalt, why they are used, where they are used in terms of applications and the benefits they offer to industry and the road user. In particular the reader will understand how polymers can be used to enhance the functionality of asphalt, i.e., to overcome deterioration mechanisms by enhancing asphalt stiffness, flexibility or making it more resistant to deformation (rutting) caused by traffic. An indexed section containing several hundred key references and abstracts selected from the Polymer Library supports this review.
