Description

Technical Field

[0001] The utility model relates to the field of a row of cutter seats, in particular to a row of cutter seats with adjustable center height specially used for diamond blades. Background Art

[0002] PCD diamond blades have high hardness but high brittleness, and can achieve high surface finish. This requires a high precision of the center of the tool tip. However, when turning with diamond blades, the center height error of the blade is large due to the insufficient production precision of the diamond blade and the tool holder, which can reach an error range of -0.05 to +0.15.

[0003] When using a gang tool lathe, it is inconvenient to adjust the tool center height, and the center height has a great influence on the cutting force, the processed surface quality, and the tool life. Ensuring that the tool center height is within a reasonable range can avoid tool vibration, obtain better surface quality, and extend the tool life.

[0004] In the actual production process, the tool height is usually adjusted by adding or reducing fixed-specification gaskets to change the tool center height. This method has a small adjustable range and discontinuous height changes. When the tool rod height changes greatly or the tool rod needs to be reversed, it is not convenient to adjust the tool center height accordingly. Utility Model Content
