Abstract

A cutting tool is provided which suppresses wear of a side surface of the cutting tool due to cutting processing. A cutting tool has a substantially circular ring shape with serrations formed on its outer periphery, wherein the cutting tool has recesses on both side surfaces. In addition, the concave portion may be formed by a plurality of grooves arranged in a grid. The concave portion may also be formed by a plurality of grooves extending annularly in the circumferential direction. The concave portion may also be formed by a plurality of grooves extending radially from the inner peripheral portion of the substantially annular cutting tool toward the outer peripheral portion. The concave portion can also be formed by a plurality of micro pits arranged regularly. The recess may also be formed by a plurality of irregularly arranged grooves.

Description

technical field [0001] The present invention relates to a cutting tool used for cutting a workpiece such as ceramics before sintering. Background technique [0002] As one of semiconductor devices used in mobile phones and the like, there is a laminated ceramic capacitor. Hundreds of these multilayer ceramic capacitors are mounted in one mobile phone, and these multilayer ceramic capacitors are mass-produced and consumed in large quantities every day. [0003] Multilayer ceramic capacitors can be produced by cutting a laminate formed by stacking a plurality of plate-shaped raw ceramics (ceramic before sintering) with a cutting machine to divide it into multiple laminates, and then sintering the laminate. . When dividing with a cutting device after sintering, the arrangement of the laminated body is distorted due to thermal deformation due to high temperature during sintering, making precise cutting difficult. Therefore, dividing is performed before ceramic sintering. [0...
