Document Type and Number:
WIPO Patent Application WO/2022/107613
Kind Code:
A1
Abstract:
A cylindrical body, according to the present invention, has ceramics as a main component, the inner surface of the cylindrical body is obtained from a roughness curve in the axial direction of the cylindrical body, and in a load curve indicating the relationship between the cutting level and load length rate Rmr, when a point indicating the value of the load length ratio Rmr at each cutting level is Rmr1 (cutting level), at least two point of Rmr1 (20%), Rmr1 (30%), and Rmr1 (40%) are above the straight line (L1) connecting Rmr1 (10%) and Rmr1 (50%).
