With the GENIS 2 product line, TYROLIT defines a new performance level and a wider range of applications for external cylindrical grinding with vitrified-bonded CBN tools. GENIS 2 is characterised by a high-strength bond with excellent moistening properties, which securely binds the CBN grain.Low bond volumes enable very porous, cool-grinding and extremely easy-cutting specifications with a long lifetime.

Following intensive research, TYROLIT has succeeded in developing GENIS - a bond system that ensures optimum wetting and coating of the CBN grain, even with extremely low bond content. By selecting the composition of the bond, at the right firing conditions crystallisation is controlled in a targeted manner.This enables the production of porous textures with high mechanical strength, which feature maximum resistance to the effect of cooling lubricants. The cool grinding specifications of our GENIS highest performance tools enable you to purposely reduce grinding forces and so make the most efficient use of the CBN grain. In all applications, practical experience shows that reduced grinding forces enable minimal wear and maximum profile retention.

With GENIS CF, TYROLIT is extending the performance spectrum of the GENIS product line with an innovative, fibre-reinforced composite core for numerous external cylindrical grinding applications. In addition to a weight reduction of up to 80%, this tool design features special damping characteristics, which result in improved grinding results and a longer lifetime.

With CSS ULTRA, TYROLIT has managed to restructure the micro-architecture of the grinding wheel with lasting effect by using high quality components and innovative sintering technology. This enables the abrasive grain to withstand much greater loads during use without breaking away prematurely. These improvements result in maximum profile retention combined with minimal wear.

With its POLARIS product line, TYROLIT is the market and technology leader in the production of galvanic bonded grinding tools. Cutting-edge production equipment, manufacturing know-how and application expertise are essential for maximum tool lives. Even the smallest amount of axial and radial run out or the slightest imbalance can reduce the service life of the tool.Additionally with the POLARIS PLUS variant, the zones with the highest levels of tool wear can be specifically reinforced, extending the life of the grinding wheel even further.

With the FaceTec MF product line, TYROLIT offers a high performanceproduct in the area of belt-superfinishing. The focus is on customers whose surface quality requirements can only be achieved by means of a superfinish machining operation.These requirements relate primarily to the automotive (crankshafts and camshafts) and steel industry (roll grinding). Becausem finishing belongs to the final operations in the value-added chain, process stability is an essential criterion. The high quality standard and the high service level make FaceTec MF to an optimal solution for critical finishing processes.

With the POLARIS LW product line, TYROLIT is a pioneer and technology leader in the area of lightweight electroplated grinding tools. Through targeted material reduction, the wheel weight has been significantly reduced.stock removal rate at the core is not random, but is calculated using a computational FEM analysis (Finite Element Method). This means that deformations and potential performance losses can be excluded. Through use of the lightweight POLARIS LW version, the maintenance intervals atthe grinding machines can be reduced and handling significantly simplified for personnel in production.

TYROLIT have extended the portfolio of diamond roller dressers with anexciting new assortment: DressTec NGR. This new product line enablesTYROLIT to offer the fastest delivery time for roller dressers in the market,whilst maintaining the highest precision and quality. This is achievedthanks to the very latest manufacturing technologies, new processingsteps and premium measuring equipment at the company’s state-of-the-art plant in Neuenrade, Germany.DressTec NGR combines quality, reproducibility and precision featureswith the fastest speed to market. This is unique within the industry.

TYROLIT is setting new standards for external cylindrical grinding using ceramic CBN with the GENIS 2 N-LW product line. The extremely low density of the patented core material N-LW delivers significant weight savings. GENIS 2 N-LW tools are lighter and most of all less expensive than comparable tools with a CFRP core. The products can be approved for wheel peripheral speeds of up to 140 m/s.The material has excellent damping behaviour and is designed with a high-precision steel mounting in the bore area. This means that GENIS 2 N-LW cores can be replaced a number of times and used in production.
