Title:
TIP SAW AND MANUFACTURING METHOD THEREOF
Document Type and Number:
Japanese Patent JP2011051062
Kind Code:
A
Abstract:

To provide a method to produce a tip saw of a sufficient quality, using hollow face type tips, wherein, when a material tip is brazed at each tooth part of a base, a cutting face side is turned down on a plane face so that it is easily stabilized when supported by each blade part, and thereby an accurate blazing is carried out.

The tip saw (S) has such a structure that a tip (2) is joined to each tooth part (10) of the base (1), and each tip (2) is a hollow face type one formed of an ultrahigh pressure sintered body in which a polycrystal sintered PCD layer (21) is laminated on a base material (20). Both edge portions of a cutting face (22) in a width direction along both side flank faces (23 and 24) formed in each tip (2), are cut and formed such that both side flank faces (23 and 24) are connected to plane faces previously formed in the same height and parallel at both edge portions.
