With ceramic, resin-bonded and electroplated grinding wheels for high-precision industrial surface and deep grinding, Tyrolit is setting new standards in terms of quality and performance.
Tyrolit develops and manufactures grinding wheels for flat and deep grinding, which are used in industrial precision applications worldwide. The range comprises wheels in shapes 1, 5 and 7, as well as rings and segments for side flat grinding – complemented by specialised product lines for the turbine and tool industries. Whether in mechanical engineering, mould making, the automotive industry or the manufacture of gas turbines and aircraft engines: Tyrolit tailors the grinding wheel specification precisely to the material, workpiece geometry and machine parameters. This enables the tightest tolerances and a perfect surface finish to be achieved consistently.
In pendulum surface grinding, the grinding wheel is guided over the workpiece with small cuts and a high table feed rate – this process is particularly suitable for flat surfaces in mechanical engineering and mould making. Deep grinding (also known as creep-feed grinding) works in the opposite way: large volumes of material are removed in a single pass using a single or a few deep cuts. The process allows for complex profile geometries and is used primarily in the machining of turbine blades, annular grooves and materials that are difficult to machine. Tyrolit is the market and technology leader in highly porous grinding wheels for deep grinding.
Nickel-based alloys place particular demands on grinding tools: the material is difficult to machine and is sensitive to heat. Tyrolit relies on highly porous, vitrified bonded grinding wheels for cool grinding – such as those from the STRATO product range – as well as electroplated tools for high-precision creep feed grinding. These grinding wheels are used in the manufacture of turbine blades, both for gas turbines used in power generation and for aeroengine turbines, to ensure maximum efficiency and consistent part quality. Tyrolit develops these solutions in close collaboration with the world's leading turbine manufacturers.
The type of bond determines how the abrasive grain is held in the tool and thus has a decisive influence on service life, cutting performance and profile retention. Vitrified bonded grinding wheels are universally applicable: they are suitable for unalloyed and low-alloy steels, high-alloy steels, HSS, stainless steel and – in conjunction with special corundum – also for nickel-based alloys. Resin-bonded CBN wheels demonstrate their strengths with high-alloy steels and HSS, whilst resin-bonded diamond wheels are ideal for cemented carbide and industrial ceramics. Electroplated tools offer the highest profile accuracy and are predominantly used for creep feed grinding in the turbine industry used, for example, for ring grooves in nickel-based alloys. Tyrolit works with the customer to determine which specification is best suited to a specific grinding process.
The range of grinding wheels for flat and deep grinding covers a wide spectrum of machine sizes and workpiece dimensions. The key factor in selection is not just the disc size, but the interplay between diameter, width and bore and the machine parameters – operating speed, feed rate and coolant supply. Tyrolit optimises the specification to meet individual customer requirements: for every application, the grain type, grain size, hardness, bond and structure are precisely tailored to the workpiece and the grinding process.

Highly porous grinding wheels are characterised by high porosity and comparatively low hardness. This combination offers two key advantages: the open structure effectively absorbs cooling lubricant and directs it straight into the contact zone, which significantly reduces the thermal load on the workpiece. At the same time, the low hardness enables a continuous self-sharpening effect – blunt grains break out of the bond, revealing new, sharp cutting edges. The result is cool grinding with a high stock removal rate, even when machining hard materials such as nickel-based alloys. For profiled wheels, there is an additional factor: highly porous grinding wheels, in combination with special sintered corundum, offer optimum profile retention with minimal dressing wear.
STRATO ALPHA is a vitrified bonded high-performance grinding wheel for surface and creep feed grinding of nickel-based alloys. The new ALPHA technology, featuring rod-shaped sintered corundum and optimised grain bonding, significantly increases service life and enables a particularly cool grinding process – whilst ensuring environmentally friendly production without the use of organic burn-off agents.
STRATO SA is an electroplated diamond-coated grinding tool that is primarily used for deep grinding in the turbine industry. It offers outstanding profile accuracy and excellent process reliability for ring grooves, and can be re-coated multiple times – which significantly reduces the total cost per component.
VIB STAR is a resin-bonded CBN grinding wheel for pendulum surface grinding of high-alloy steels and HSS. The vibration-damping backing system ensures a consistent, smooth grinding process, whilst the continuous self-sharpening effect guarantees high dimensional accuracy and minimises the need for dimensional checks.
According to Tyrolit, the company is the market and technology leader in highly porous grinding wheels for deep grinding. The company backs up this claim with over 500 international patents and a global team of application engineers who provide on-site support to customers directly at their machines. The ALPHA technology – a carefully optimised process for the production of rod-shaped ceramic abrasive grains – sets a new benchmark for ceramic bonding. In close collaboration with leading manufacturers from the turbine, tool and automotive industry tailor-made grinding solutions are developed which not only optimise process parameters but also demonstrably achieve productivity gains and lower costs per component.
