As no two projects are the same - so sometimes getting the right speed is tough - Contact our team anytime on 07 3217 9877 to make your TOUGH JOBS EASY! Ask about our concrete grinders for sale.
In every concrete floor project, there are many applications that todays' contractors come across. Be it removal of glues, paints or coatings through to the rapid removal of concrete and stripping back of epoxies or line markings (to name a few).
The Schwamborn Floor Grinding System offers a wide range of diamond tooling and scarifier attachments for most professional grinding operations allowing you to achieve maximum productivity and the perfect finish every time.
Why the Easy Tool Exchange System for Floor Grinders?
- Saves time in changing diamonds
- Gives greater flexibility with diamonds
- Saves time in preparation and removal
- Integrated air channel provides dust flow around the diamond and allows the diamond to cool giving a longer life
Diamond Selection for my machine -
Productivity, speed and the finish are all dependent on the configuration the diamonds are set up on, under your machine. Generally, on the Base of the Schwamborn Grinders - there is an opportunity for 2 different configurations - ½ or a Full plate.
Metal Bond Diamonds, is the term suggesting that diamonds are fixed in a metal compound. These diamonds are used for coarse to medium grinding applications from a 16 to a 150 grit finish.
The Grit - is the term for the size of the diamonds. The fewer segments the more aggressive. The more segments the less aggressive and in turn the smoother the finish. Grit refers to the finishing qualities of the diamond.
Grinding with the Schwamborn Floor grinder the most common cut is with a 20/30 or 40/60 grit Knock on diamond grinding shoe.
Coarser or lower the grit - the sharper and faster the cut will be. Finer grits will create a smooth surface and slow down the productivity but will work in the finishing or polishing process. Usually, 60-80 grit shoes are used in the process of polishing with 100-150 being a final cut prior to resin backed polishing pads and the adaptor plate.

Diamond Grit - Grinding Patterns
Diamond Glazing
Depending on the floor conditions, diamond grinding shoes may have poor grinding performance or pattern. The diamond starts glazing. By choosing another diamond, grit or bond, change diamond turning direction or add water to the surface to help improve the grinding speed and rectify the glazing.
Diamond Consumption
There are clues when grinding to tell if you are wearing through the diamond too fast. Take a look at the edges of the diamond grinding segment - as a sign. If there are long sharp edges - change to a harder bond diamond.
Floor Grinding & Preparation ? Tips & Tricks for your Diamond Grinder
When it comes to floor grinding and preparation there are a few things to consider to ensure you get the right fit diamond for your project.
We've put our heads together from our experience and with some seasoned professionals to provide a basic overview on HOW TO CHOOSE THE RIGHT DIAMOND GRINDING SHOE OR WHEEL below;
| Floor Surface Type | Solution on what diamonds to use, | |
| 1 | Unknown floor conditions | Start with a medium soft (HC) or soft diamond bond (VSF). |
| 2 | Soft, open and porous floors | Start with a hard bond (SC) or medium-hard diamond bond (GC). |
| 3 | Very hard and trowelled floors | Start with a medium soft, soft or very soft diamond bond (HC or VSF). |
| 4 | Low grinding performance = Diamond glazing |
|
| 5 | Quick diamond consumption |
|
| 6 | Machines move hard or switches off |
|
| 7 | Coating removal | Work with 50% overlap to get a better result |
| 8 | Scarifying & shot blasting | Floor grinding achieves a more uniform surface compared to shot blasting and scarifying. |
| 9 | Hard Floors: Grinding becomes non-productive |
|
| 10 | Soft Floors: Diamond tools wearing too fast |
|
| 11 | Bolts and metal object in the floor | Any objects in the floor must be cut or removed to prevent damage on machine and tools. |
| 12 | Cracks in the floors | Use cement based filler, for holes and close joints |
Resin Bond Diamonds, are diamonds fixed in resin compound. Used for medium to fine grinding applications from a 50 - 3500 grit finish. Resin bond diamonds are the professional diamonds for Concrete Floor Polishing, and run through the grits from 50 grit, step by step through to 3000.
The wear rates of Resin bond diamond pads varies from project to project. Most floors are ground with a Metal Bond Diamond (Grit up to 60/80 or 80/100) prior to starting on the Resin bond polishing process.
Hybrid Diamond Polishing Pads, is a mixture of a metal and a resin bond diamond. Used after metal bond diamonds the Hybrid pads are a transition tool for quick scratch removal from the floor. Proven, the Hybrid pads give high grinding performance and can be used in wet or dry applications.
PCD Diamonds are the term for Polycrystalline diamonds. Designed for a high speed, fast, aggressive removal of glues, paints, coatings or epoxies - thicker than around 3mm. Each project stands on its own so it's best to discuss your specific concrete grinding disc requirements with the All Preparation Equipment team on 07 3217 9877.
