The Type 1 straight grinding wheels, both non-reinforced and reinforced with fibreglass discs or/and steel rings and, if necessary - with fine grit zone, form the most numerous group of general purpose and specialized abrasive tools. They are intended for precision and rough grinding on various materials such as hard and soft steels, stainless steels, cast iron, aluminium, bronze, brass, concrete, stone, terrazzo, ceramics and for sharpening of cutting tools.
They are used on fixed and swing-frame grinding machines, electric and pneumatic hand-held grinding machines, sharpening machines and grinding units. The Types 5 and 7 grinding wheels are intended for rough and precision grinding on various materials, tool sharpening, etc., e.g. grinding of terrazzo, ceramics (e.g. parapet walls, stairs) on hand-held grinders with so called “flexible shaft”, for grinding of turnouts with carriage grinding machines.
