Grinding Wheels for Rotating Cutting Tools
Grinding Applications for rotating cutting tools
Grinding Wheels in our portfolio can be used for both production, or re-sharpening of all kinds of Rotating Cutting Tools: end mills, burrs, thread mills, hobs, slab mills, or any other tools.
Available products and services
We produce grinding tools of all shapes (1A1, 1V1, 11V9, 12V9, etc.), sizes, different types of abrasives (diamond or CBN) and also with different bonding agents (bonds for short).
How do we innovate grinding wheels for rotating cutting tools?
Let us help you select the right wheel by telling us a bit about your grinding application:
- Are you producing new tools from scratch, or re-sharpening old ones?
- What are your grinding conditions?
- Are you using coolant, or not?
- Do you work with high-/low-powered CNC machine, or manual machine?
- How are you going to grind.
- What is the RPM of your grinding wheel? Can you adjust it?
- What is the feedrate in mm/min or inch/min
- How much material do you want to remove in one pass? What is your infeed in mm, or inch?
Our wheels are suitable for grinding machines like:
Walter, Anca, Rollomatic, Schneeberger, Michael Deckel, Reinecker, Haas, Saacke, Vollmer, Havemat, Schütte, etc.
Types of bonds for grinding of rotating cutting tools
Hybrid bonds
(Flute – Speed®)
Our hybrid bonds are called Flute – Speed®. These bonds are a result of many years of research and development. Hybrid bonds in general, combine the best of features of resin and metal bonds – ease of grinding and edge retention (respectively).
Therefore, Flute – Speed® wheels are perfect for one of the most demanding grinding applications – production of new rotating cutting tools.
They come in all shapes and sizes, so they can be used for all kinds of operations – fluting, gashing or clearance grinding operations.

| Type of Abrasive | Wheel type | Cutting Speed (m/s) | Feedrate (mm/min) | Infeed, i.e. depth of cut (mm) |
| Diamond | Peripheral wheels 1A1,1V1, etc. | 16 – 18 | 80 – 120 or 160 – 200 (newest version) |
~4 mm (depends on application) |
| Cup Wheels 11V9, 12V9, etc. | 22 | |||
| CBN | Peripheral wheels 1A1,1V1, etc. | 22 – 25 | 80 – 120 or 160 – 200 (newest version) | ~4 mm (depends on application) |
| Cup Wheels 11V9, 12V9, etc. | 30 |
Above-displayed grinding conditions are only indicative. Optimal solution for your grinding application might vary and requires testing.
Approach us to secure a testing wheel.
Multiple factors affect grinding performance – cooling, specific type of grinding application, diameter of the workpiece, etc.
All grinding parameters have inverse effect on each other, i.e. increasing Feedrate, Infeed, or Cutting Speed have to be decreasing and vice versa.
Resin bonds
Our resin bonds are a great fit for multitude of applications, where our special bonds (hybrid and metal) don´t generate value for our customers, because of their higher price.
Generaly speaking, resin bonds combine very good edge retention (better than hybrids, but not as good as metal bonds) and performance (better than metal bonds, but less good than hybrids).
We have many types of resin bonds in our portfolio. To identify the most fitting resin bond for you grinding job, we need you to share with us more information about your grinding condition.
We offer resin bonds for both:
- Dry / wet grinding
- CNC / semi-automatic grinding machines
- Re-sharpening / Production of new tools (applies to gashing / clearance angle grinding operations)
- E-C3 – New resin bond for perfect edge retention in difficult grinding applications. Download leaflet for more information HERE.
| Type of Abrasive | Wheel type | Cutting Speed (m/s) | Feedrate (mm/min) | Infeed, i.e. depth of cut (mm) |
| Diamond | Peripheral wheels 1A1,1V1, etc. | 20 – 25 | 130 – 280 | Up to 2,5 |
| Cup Wheels 11V9, 12V9, etc. | 60 – 70 | Up to 1 | ||
| CBN | Peripheral wheels 1A1,1V1, etc. | 20 – 25 | 130 – 280 | Up to 2,5 |
| Cup Wheels 11V9, 12V9, etc. | 20 – 40 | 70 – 80 | Up to 1,5 |

Metal bonds
Metal-bonded grinding wheels are ideal for production / re-sharpening of very small cutting tools, or production of shapes with high accuracy (e.g. grinding of tap cutters, profile grinding of dental burs, etc.).
Main benefit of metal bonds is very high shape shape stability. This comes at the cost of lower removal rates of material.
Standardly, we manufacture metal-bonded wheels with precision of 0,03 mm. Higher precision achieavable upon consultancy with our technicians.
When grinding with metal-bonded, it is not possible to remove very big amount of material at the same time in comparison to resinous or hybrid bonds. However, the main benefit when grinding with Metal-bonded Wheels is the very high edge retention and thus can be used for production of hundreds of tools.
Infeed / depth of cut will be very small – usually around 0,3 to 1,0 mm per 1 pass of the grinding wheel, depending on the feedrate (mm/min) and velocity of the grinding wheel.
Peripheral Velocity of the grinding wheel will vary between 15 to 25 m/s. Depending on wheel´s diameter.
Feedrate can vary between 60 to 200 mm/min. Depending on Infeed and Peripheral Velocity.
Polishing bonds
In some cases, our customers want to achieve mirror-like surface finish of their end mills, drills or burs. Examples could be rotating tools for processing of:
- Aluminum, copper and brass
- Laminated materials
- Plastics
- Titanium
- Wood
Cutting tools with polished cutting edges have better chip removal, perfect cutting edge geometry, no chunking, better surface quality, or reduced power consumption of the machine tool.
For these cases, we have developed a special polishing bond that meets these requirements and allows achieving Surface Roughness (Ra) of 0,025.
Using polishing wheels successfully, requires increased focus on qualitative aspects of grinding, i.e.:
- Good balancing of the grinding wheel. Ideally, the wheel should be produced already fixed on a flange.
- Grinding wheel should be dressed while mounted on the customer´s own spindle that will be used in the grinding machine. For extra cost we can manufacture a copy of the customer´s spindle when provided with technical drawing.
- Grinding machine and spindle bearing must be in good condition.
| Wheel type | Cutting Speed (m/s) | Feedrate (mm/min) | Infeed, i.e. depth of cut (mm) |
| Peripheral wheels 1A1,1V1 | 20 – 30 | 50 – 100 | 0,1 |
| Cup Wheels 11V9 | 50 – 100 | ||
| Cup Wheels 12V9-45° | 20 – 60 |
