Title:
BONDING TOOL
Document Type and Number:
Japanese Patent JP3862815
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To ensure excellent flatness and abrasion resistance of tool working face and a sufficient bonding strength between the tip of a tool and a shank by brazing the tip of a tool, obtained by depositing polycrystalline diamond on a sintered substrate, to the shank made of an austenite based low thermal expansion cast iron thereby facilitating the machining.
SOLUTION: The tip 14 of a tool, obtained by depositing polycrystalline diamond on a sintered substrate, is brazed to a shank made of an austenite based low thermal expansion cast iron to obtain a tool for enhancing machinability of the shank, flatness of the working face of the tool, and the positional accuracy with respect to an apparatus fixing part 11. Strain at the joint due to difference of thermal expansion is relaxed at the time of brazing the shank and the tip 14 of the tool and flatness is sustained at the tip 14 of the tool even if heating and cooling are repeated. Furthermore, a high bonding strength is attained because the austenite based low thermal expansion cast iron exhibits a good wettability to many brazing filter metal.
