Description

[0001] The utility model relates to the field of crystal processing, in particular to a tool fixing device for precisely determining the direction of a crystal during sand line cutting and adjusting trial cutting. Background Art

[0002] In modern industrial processing, especially in high-precision processes like crystal cutting, the way workpieces are fixed plays a crucial role in determining machining accuracy and efficiency. Traditional tooling fixturing techniques typically use direct clamping to secure workpieces to processing equipment. While this method can ensure workpiece stability to a certain extent, it has significant limitations and drawbacks in actual operation.

[0003] During the crystal cutting process, to ensure that the cut surface conforms to a specific crystal orientation, auxiliary equipment such as a microscope is often required for observation and judgment. However, with traditional fixing methods, once the crystal orientation is determined, any fine-tuning must be done by re-clamping and adjusting. Each adjustment requires the operator to manually reset the fixture, a time-consuming and labor-intensive process that not only increases the difficulty of the operation, but also prolongs the processing cycle and affects production efficiency.
