How to Choose the Right Diamond Blade According to Cutting DepthBlog | September 10th, 2019
Diamond blades can be expensive, so there’s not much room for trial-and-error testing. Besides, seeing a tool operator haphazardly selecting a blade, well, that’s not exactly a professional workflow. No, journeymen level expertise requires assignment preplanning, not a blind take-your-chances approach. So, if a desired cutting depth is to be reached, the following challenges must first be addressed. Let’s start with the rim geometry of a depth-capable diamond blade.
Segmented Rims Cut Deeper
It’s only common sense, after all. A continuous rim blade cuts clean, finely detailed edges, but it won’t ordinarily go deep. Segmented rims operate cooler and are designed to self-remove cut debris as they penetrate. A cooling stream of water further aids this action. Okay, with that principle firmly in mind, let’s add a few more deep-cutting features. An increase of diamond density, a change in the size and height of the segments, plus a matching alteration to the geometry between the rim sectors, all of these blade attributes help the tool to sink deeper into hardened blocks of super-dense materials.
Operator Controllable Deep Cutting Factors
Assigned with a penetrative cutting job, an equipment rig that’s designed to cut deep is selected by the contractor in charge. It’s fitted with a high-diameter diamond blade. It also delivers plenty of power to the tool spindle. Remember, the surface of the blade will be rubbing against a hard material as it makes its incision, so a high-torque machine is essential. A cooling medium accompanies the segmented rim, as it’ll generate copious quantities of frictional energy when it makes its deep incision. A dry blade is not going to cut as deeply, not without aging the blade and producing enough blade-fracturing heat to impact the cut zone.
Equipment-Adjustable Cutting Depths
Generally speaking, the blade is loaded with numerous cutting features. For depth-oriented work, the size of the blade, its segment geometry and disc thickness ensure a hassle-free entry that’ll sink deep. The equipment operator has much to contribute before the tool begins its work, though. On consulting a manual, he adjusts the feed rate so that the equipment’s forward RPM matches the selected blade diameter. By the way, deep incisions are rarely if ever made in one go. Even with the right diamond blade fitted and a high-torque equipment motor running, the process must be carried out in stages. Multi-step passes are typically utilized when implementing a depth-penetrating cutting assignment.
The right diamond blade for a deep cut job has a suitable rim geometry and blade width. It’s tensioned correctly so that it won’t warp when asked to penetrate a dense block of concrete. Similarly, with aggregate materials and refractive substances in mind, other relevant features are added. These include slot gullets, higher-quality synthetic diamonds, and stronger steel cores.
