Title:
METHOD OF MANUFACTURING CORE DRILL BASE, AND CORE DRILL BASE OBTAINED BY THE SAME
Document Type and Number:
Japanese Patent JP2014240175
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an inexpensive method of manufacturing a core drill base, which does not cause deflection or deformation and which has high productivity, and the core drill base obtained by the same.SOLUTION: A welding step is eliminated, and a head part and a cylinder-like trunk are joined together by combining an adhesive and geometric structural means such as a screw thread. Thus, a core drill base with small deflection is inexpensively provided with high productivity by a simple method.
