The method comprises the following steps that: firstly, the element blank body after dry pressing and molding is subject to preburning treatment; a preburning temperature is between 700 and 1,100 DEG C; a grinding medium, water and a preburned element blank sheet are put into a planetary grinding tank for carrying out sheet grinding treatment; and finally the element blank sheet is cleaned and dried. The product produced by removing the raw edges by the method has smooth and flat appearance, no raw edges, no collapse and other poor phenomena. The method is used for removing the raw edges of the sensing element blank body, and the qualified rate of the appearance of the ground sensing element blank body reaches 99 percent above.
Description
Technical field
The present invention relates to element base substrate processing technique field, relate in particular to a kind of method of removing sensing element base substrate burr.
Background technology
The existing method of removing the element base substrate is: the ceramic body that will sinter is put into ball grinder and is added the water wet-milling, utilize the friction between ceramic body that burr or burr are removed, owing to be to utilize the rigid collision between ceramic body to reach the purpose of removing burr in the process of mill, and ceramic body enbrittles, and causes ceramic body to collapse problems such as limit or fracture.Perhaps the surface of ceramic body that will sinter with the method for machining polishes, and this method is applicable at present in the production of the ceramic body that volume is bigger that this method also can exist ceramic body to collapse the limit bad phenomenon.Put into the vibratory sieve vibration again or with the base substrate of firm forming, utilize the friction between base substrate that burr are removed, but this method also has certain limitation, it is bigger generally to be used for size, and on the higher solid device of base substrate hardness, for the lower small-sized or hollow device of blank strength, this method also can cause to the ceramic body edge and collapse not phenomenon of limit, even mashed sheet problem appears, and this method is to the tiny burr of burr height less than 0.05mm, and removal effect is bad.
Summary of the invention
The technical issues that need to address of the present invention are to remove the burr of element base substrate, make the ceramic body surfacing smooth, do not have bad order phenomenons such as collapsing limit, mashed sheet, improve the yields of producing.

Further: described planetary mills jar rotating speed is 35 ± 5 rev/mins, and the time is 5～15 minutes.The described pre-burning time is 2～5 hours.Described mill Jie high temperature calcined temperature is 1000 ℃～1300 ℃.The described sieve number of sieving is 100～120 orders.Ceramic powder particle is the dry powder before the element blank forming.
Use said method to remove the product of rough edges of element base substrate gained, product appearance is smooth smooth, and no burr, nothing collapse mashed bad phenomenon, and this method is used to remove the burr of small-sized sensing element base substrate, and mill back sensing element base substrate appearance yield reaches more than 99%.Satisfy electrode printing and client requirement to the ceramic body outward appearance.
