Grinding wheels factory Swaty was established by chemist Franz Swaty in 1879 so that it is one of the oldest European pro-ducers of grinding tools.At the beginning the production was based on a patented procedure for production of grinding wheels in mineral bond. Thisproduction was abandoned in 1958 when it was substituted by up to dated production programmes.To meet the increasing demand of industry the production of grinding wheels in vitrified bond was introduced at the end of1929.The production of grinding wheels in resinoid bond, at present the strongest production line, was started in...

The grain size is designated by means of numbers according to the ISO Standard 8486. Acomparison of the national grain-size standards Micro-granulation > 1234512345 1 = ISO 8486, DIN 691012 = ANSI B 74.12-1976 (USA) 3 = JIS R6001-1973 (Japan) 4 = GOST3647-71 5 = PN-76 M-59115 (Poland) 50% value of sedimentation curve The hardness of the grinding tools is proportional to the bond strength with which a single grain is tied in the bond-matrix.It depends on the following: The quantity and type of bond Օ The structure The type of the abrasive grain Օ Grinding tool making procedure The grade of...

BOND Vitrified bond Resinoid bond The main components of vitrified bonds are clays, kaolin, feldspar, frits and other ingredients. During the burn- ing in ceramic kilns the components are partly fused and sintered. They also interact and during cooling they change into a state similar to glass or porcelain. Vitrified bond is brittle, it has no elasticity and is quite resistant to deformation. It is sensitive to impact, percussion, high load and changes in temperature. It is unaffected by moisture and dampness at temperatures higher than 0 C. The main components of resinoid bonds are...
