Title:
GRINDING METHOD
Document Type and Number:
WIPO Patent Application WO/2005/049270
Kind Code:
A1
Abstract:
A method for grinding the outer circumference of a work (5) formed of a fragile material, while rotating the work (5), into a specified shape by means of a grinding wheel. After performing plunge grinding for grinding the work (5) by cutting the grinding wheel into the direction intersecting the rotational axis (8) of the work (5) at an appropriate part (plunge grinding part (21)) in the longitudinal direction of the work (5), traverse grinding is performed toward the plunge grinding part (21) for grinding the work (5) by moving the grinding wheel relatively to a direction parallel with the rotational axis (8) of the work (5). Thus, the outer circumference of a work made of a fragile material, e.g. a honeycomb structure of DPF, can be ground into a specified profile in a short time while preventing occurrence of chipping incident to grinding.
