A diamond cup wheel is a tool that uses an abrasive, high-speed, rotating wheel to shave or finish a surface area – typically concrete.
Diamond cup wheels are designed to grind down, smooth, and remove the flashing from concrete and other masonry materials.
Creating starkly beautiful smooth concrete floors is just one of their many uses. Diamond cup wheels can also be used to remove paints, polish, glues, epoxy, wallpapers, and other coatings, and can also be used to cut concrete and grind edges.
To ensure a fast and even grind, it is important to protect your grinding wheels from wear and tear.
In this blog, we will talk about the different types of diamond cup grinders and how to keep them in good working order.
Different Grinds for Different Types
Before we get into how to look after your diamond cup wheel, it is important to note that there are many different kinds of grinders available. However, there are four main types that you should be aware of as a baseline:
Double Row Cup Wheel
This is a heavy-duty grinder designed for aggressive lumps, bumps, and materials that need extra power to smooth down to a flawless polish. These grinders are built to last and suit heavy masonry materials such as natural stone and dense grainy concrete.
Turbo Cup Wheel
Suitable for coarse and fine grits, this grinder is a versatile all-rounder and can even tackle columns and pipes.
TGP Cup Wheels
TGP segmented cup wheels run cool and even over aggressive surfaces. This high-speed grinder is excellent for surface preparation and cutting.
Arrow Cup Wheel
Arrow-shaped segments make this an aggressive, top-quality wheel that can take on the tough surfaces with minimal gumming, including light coatings and resin.
Looking after your Diamond Cup Wheel
Diamond cup wheels are designed to be strong, but that doesn’t mean they can be handled carelessly. Like all important tools, they benefit from care and regular maintenance. In fact, some diamond cup wheels have brittle components that won’t hold up against bad handling, so it pays to treat them kindly.
Before you use your diamond cup wheel it’s important to read the user manual thoroughly. This will give you a good insight into its advantages and limitations. You may even discover hidden capabilities you didn’t even know about!
Next, check that all the parts are in good working order, including the switches and plugs, as well as the grinding wheel itself for signs of wear or damage.
Next, ensure that the materials you wish to grind down and smooth are suitable for your particular diamond cup wheel.
You’ll also need to check whether your materials should be wet or dry.
Use a vise to secure your materials in place and install a ventilation system to remove debris and dust from your tool.
For the longevity of your grinding cup wheel, it is important to follow the manufacturer’s instructions for mounting and tightening the nut.
You should also file off any burrs on the surface of work.
Pay attention to dressing and pitch
Keeping your wheel evenly dressed, AKA sharpened, will also extend its lifespan. A ground down wheel still has a lot of use left in it, especially if you take the time to dress and return it to its original caliber.
The manufacturer of your wheel will have product-specific advice on dressing, so the next thing you should pay attention to is the wheel alignment. You need a properly aligned wheel to achieve a precise cut and grind, so this one is worth keeping your eye on. If your wheel is not aligned then this can quickly wear away its profile shape and blunt the blade.
Finally, a tip from the construction workers themselves: use your ears. From the ring test to the pitch emitted while your cup wheel is in operation, the sound will tell you a lot about its current condition.
