PG-9BHD Centerless Form Grinder

Glebar Co. delivered a solution for grinding deodorant balls while reducing cycle times and improving throughput. Glebar developed ball grinding for the golf ball industry in the 1960s using centerless grinding fundamentals. The process was adapted to grind deodorant balls and other spherical or cylindrically shaped components. Glebar machines can grind most hard-to-turn materials such as carbon fiber, fiberglass and polypropylene.

6S and 6L Grinding Machine Series

New linear motors and well proven hydrostatic guides in the 6S and 6L grinding machine series open up new potential. Higher speeds, various detailed improvements and optimized ease of maintenance result in shorter cycle times, maximized quality and cost savings. The expanded modular concept for the table assemblies makes the platform 6 grinding machines more flexible and adaptable.

Are grinding machine safety guards overdesigned?

Guards on grinding machines are particularly important for ensuring operator safety. Grinding wheels seldom burst, but when they do, there is a great risk of serious injury to the machine operator. Recent studies suggest, however, that the enclosures commonly used in gear grinding machines, for example, could be overdesigned at present. Investigations conducted by the VDW (Verein Deutscher Werkzeugmaschinenfabriken – German Machine Tool Builders' Association) and the Institute of Machine Tools and Factory Management (IWF) at TU Berlin reveal that it is possible to use safety guards which are up to 70% thinner, depending on the width of the grinding wheel. These findings are leading to changes in ISO standardization.

DIT 716 Series Diamond Dressing Tool

Many years ago, the Super 716 Series diamond tool was made for dressing large and wide precision grinding wheels on centerless, cylindrical and surface precision grinding machines. They were made to minimize glazing and the closing up of the wheel surface. They were also made to carry the large wheel without taper or the crushing of the bond. It worked better than any other grit or impregnated dressing tool.

Norton Stellar Inserted-Nut Grinding Wheels

Saint-Gobain Abrasives announced the introduction of its new Norton Stellar inserted-nut grinding wheels for double- and single-disc grinding that offer improved wheel life, increased parts per wheel and lower cost per part. The new grinding wheels are suitable for a wide range of industries including automotive, bearing, tool manufacturing, compressors, knife blades and job shop and general machining.

«mini-contour» Wheel Sharpening Machine

Lach Diamond Inc. developed «mini-contour» machines, a special sharpening machine that can produce high-precision concave and convex profiles from 2 to 4 µm and is suitable for re-sharpening the company's »contour-profiled« grinding wheels.

»contour-profiled« Profile Grinding Wheel

Lach Diamond Inc. offers a grinding wheel with a metal bond for deep grinding – hitherto almost unthinkable. For the first time, newly developed bond variations are available for profiling during the deep grinding of carbide, high-alloyed steel, ceramics and, in a special specification, even unhardened steel.
