Title: Ceramics-made center and its usage
Inventor: YAMASHITA AKIO
IPC: B23B23/00
Filed: 1989-01-13
Abstract: PURPOSE:To increase the strength and anti-wear property by providing a ceramics sintered body, composed of zirconium oxide and aluminum oxide both containing stabilizing agent with required strength and toughness, at the tip of a shank. CONSTITUTION:An example of the production of a sintered body to be used at the tip 2 of a shank 1 is explained here. Al2O3 powder is put into a container lined with polyurethane together with the ball of Al2O3-ZrO3, mixed and ground for 10 hours under methanol wet and, after PSZ powder is added, mixed and ground for 48 hours. The mixed powder is liquid-pressed after drying at a pressure of 1.5t/cm<2> to form a powder compact. The powder compact is kept in oxygen gas flowing in at a rate of 1l/sec. and at a temperature of 1,500 deg.C for 2 hours, to sinter it. Then it is hot-treated hydrostatically in Ar gas under a pressure of 1,500atm and at a temperature of 1,300 to 1,400 deg.C, to form a sintered body. Thus zirconium oxide increases the strength and toughness of the center and aluminum oxide increases the anti-wear property of it.
