HIGH-STRENGTH DAMPING ALLOYS AND LOW-NOISE DIAMOND SAW USING THE SAME

摘要

High-strength clamping alloys and a low-noise diamond saw using the same are provided. Preferable types of alloys, compositions and processing amounts to be applied to a shank of the diamond saw are suggested. The shank of a welded type diamond saw is increased in hardness by adding 14 to 28% by weight of Mn to Fe and cold-rolling them within the range of 2 to 25%. As a result, the hardness is increased to a standard value (HRC35) and above, and the noise reduction effect has been significantly increased. The shank of a sintered type diamond saw is increased in strength by adding 10 to 28% by weight of Mn to Fe, followed by heat-treating them. The mechanical performance can be further increased by cold-working the shank to by 20% or more prior to sintering.
