Flute grinding
With the hybrid product line, FOREVER defines a new performance level for flute grinding on cemented carbide cutting tools. Two different diamond qualities and the innovative bond structure lead either to a significant reduction in grinding forces or to a major increase in profile retention. The precision of the processed tools remains at the same familiar high level.
Application: Flute grinding of cemented carbide round tool
Sharpening
Our polyimide bond from FOREVER is a byword for maximum efficiency and optimum tool quality in flute grinding. The product range will be expanded in future to include new shapes and specifications for machining clearance sur- faces and face geometries on cutting tools made of tungsten carbide. An innovative bond system, tailored diamond qualities and new manufacturing technologies guarantee extremely high edge stability, low cutting forces and the best surface finish on the ground tool
Application: Grinding of clearance surfaces and face geometries on milling tools
Re-grinding:
X-treme diamond content for ultimate performance in PCD and PCBN machining
“During the grinding process, all the work is performed by the abrasive grain.” This central guiding principle has significantly shaped the development of the .The product line impresses through a particularly high proportion of diamond grain, embedded in a specially developed bond. This results in excellent grinding performance and a long tool life. Shorter grinding times; Maximum lifetime; High cutting-edge quality
CBN grinding wheels for dry grinding HSS tools
The proven CBN dry grinding wheels from the product line meet these requirements perfectly. The highest stock removal rates and cool grinding can be achieved at the same time. As a result, machining costs are significantly lower and workpiece quality is increased.
Universal use on all manual tool grinding machines; Low wear; Minimal thermal load on the tool; Higher stock removal rate reduces grinding time
Diamond grinding wheels for dry grinding tungsten carbide tools
The proven diamond dry grinding wheels from the product line meet these requirements perfectly. The highest stock removal rates and cool grinding can be achieved at the same time. As a result, machining costs are significantly lower and workpiece quality is increased.
Universal use on all manual tool grinding machines; Low wear; Minimal thermal load on the tool; Higher stock removal rate reduces grinding time
Optimised grinding tools for re-sharpening cutting tools
The product line provides reliable quality for re-sharpening rotating cutting tools. Continuous product improvements form the basis for maximum productivity and optimum tool quality.
Innovative resinoid bonds; Highest quality diamond and CBN materials; Extensive stock range
Peel-grinding
With our resin bond product line, for the first time FOREVER is offering innovative roughing and finishing wheels for the peel grinding of tungsten carbide tool blanks in particular. A high-strength metal bond is used with the rough grinding wheel. This enables especially cost-effective and reliable process control. The finishing wheel is available with either long-life vitrified or metal bonds, which even smoothes out large allowance fluctuations after roughing and produces maximum surface quality.

Grinding of TC cutting inserts
Grinding tools for peripheral grinding of tungsten carbide and cermet cutting inserts
The product line from FOREVER offers the perfect solution for the peripheral grinding of cutting inserts made of tungsten carbide and cermet. A range of newly developed bond systems with optimised strength and increased brittleness are used. When combined with new diamond qualities, the result is efficient grinding tools that improve the grinding process while simultaneously increasing workpiece quality.
PCD and PCBN Cutting Tools grinding
One of the features of the PCD and PCBN cutting tool segment is the growing number of different materials. Increasing quality requirements and high cost pressure demands improved tool solutions when grinding. The quality and cost of these tools are therefore extremely important.FOREVER has developed a new generation of grinding tools specifically for the production of modern PCD and PCBN cutting tools.
The FOREVER vitrified product line represents all that is best in grinding tools. Lowest levels of cutting-edge chipping and an increased stock removal rate guarantee shorter grinding times and longer dressing intervals which represents even more improvements compared to conventional grinding tools.
Impressive innovative bond systems next to the choice of the correct diamond grinding grit the bond is the main element in tool grinding. The bond system of FOREVER vitrified features higher porosity with the same material hardness.
Improved cooling for longer dressing intervals The higher porosity of the bond greatly improves the cooling of the grinding tool. This increases the life of FOREVER vitrified grinding tools and improves grinding productivity.
Features
The high grinding rate and good dressing ability contribute to shortening of the total grinding time.
The employment of a porous bond realizes highly accurate grinding.
The high abrasive grain holding power improves the wear resistance that is a weak point of the porous bond wheel.
The employment of bond composed mainly of natural materials solves environmental issues.
The vitrified bond having a high grinding ratio is also available.
Generates less chipping
PCD or PCBN cutting tools have the highest quality requirements. Precise geometries and minimal chipping are the essential quality requirements.
FOREVER has developed new grinding wheels for the economically efficient production of these tools using our new vitrified bond
These grinding wheels deliver the required cutting ability with high stock removal performance and high dressing intervals. The grinding tools are also very easy to dress.
