In the given work specific characteristics of deterioration of band saws are considered that allow to predict sawing up process and raise firmness of the tool and its productivity.

Deterioration of teeth of a band saw on a back surface was measured in process of experimental sawing up material in diameter by 160 mm, which was steel 45. We applied the band saw machine model С8523 Joint-Stock Company "special design bureau ALMS" As a tool was used bimetallic band saws of firm "Rongen" in height of 27 mm with variable step of teeth at length of 25,4 mm As applied 10 % of a solution emulsion.

The band saw has many teeth which of them cut only small part in time of cutting. Sawing up by a band saw is one of the most effective ways of cutting considering distribution of heat and effort of cutting.

Deterioration of teeth of a band saw is typical to the mechanism of deterioration of other cutting tools. And still deterioration occurs in unusual way. Teeth wear out in the localized zones - on a back of a tooth and on its lateral surfaces where the tooth contacts to a processed material. At definition of firmness intensity of deterioration of a band saw is the most convenient for defining at measurement of deterioration of teeth on a back surface. Deterioration can be divided into three zones: a zone extra earnings, an operating conditions and a zone of critical deterioration during which time it is necessary to replace a saw.
