The specific operation steps of forming and dressing of zirconia ceramics

In the process of tensile test pieces of zirconia ceramics, the forming and trimming of ceramics is also a very important step. The following Kezhong Ceramics Factory will give you a detailed introduction to the specific steps of ceramics' maintenance.

In order to ensure that the forming and trimming can be carried out successfully, the following steps must be followed:

① Balance the grinding wheel first before installation.

②Put the forming dresser on the grinding table, adjust it with the help of a dial indicator to ensure that the motor shaft driving the silicon carbide grinding wheel is parallel to the main shaft of the grinding machine, and then lock the dressing device.

③ Drive the silicon carbide grinding wheel at a low speed, and its linear speed is generally 3-5m·s-or lower, so that the electroplated diamond sample block contacts the silicon carbide grinding wheel with a certain pressure until the contour of the silicon carbide sand is consistent with that of the diamond sample block.

④ Dress the diamond grinding wheel with the trimmed silicon carbide grinding wheel. At this time, the speed of the silicon carbide grinding wheel is 22m s-1, the speed of the diamond grinding wheel is 3m s-1 or lower, and the depth of cut is generally 0.01-0.03mm. totally agree.

⑤ Place a thin metal sheet and grind it to determine whether the profile is correct.

If it is not correct, repeat the above operation from step ③; when the profile is close to correct, increase the speed of the diamond grinding wheel to 10-15ms or the speed of normal grinding; if the profile is correct, the diamond grinding wheel is repaired. When dressing silicon carbide grinding wheels with electroplated diamond samples, the speed of the grinding wheel must be low, and the pressure should not be too high, otherwise, the electroplating layer will peel off or be worn off.
