Title:
METHOD FOR MANUFACTURING CERAMIC FILTER
Document Type and Number:
WIPO Patent Application WO/2016/121785
Kind Code:
A1
Abstract:
Provided is a method including: a preliminary grinding step for driving rotation about a first axis L1 by a honeycomb structure provided with sealing parts at a first end 120a and a second end 120b in the lengthwise direction, grinding the honeycomb structure while a first rotating grindstone 20 or a second rotating grindstone 10, the distance of which from the first axis L1 is controllable, is moved from the first end 120a toward the second end 120b of the honeycomb structure, the first rotating grindstone 20 being harder than the second rotating grindstone 10, and using the first rotating grindstone 20 to grind hard sections of the honeycomb structure including the first end 120a and the second end 120b; and a main grinding step for using the second rotating grindstone 10 to grind the honeycomb structure. When manufacturing a ceramic filter, in the step for grinding the honeycomb structure, wear of the grindstones or other grinding members can be prevented.
