Description

Technical Field

[0001] The utility model relates to the technical field of multi-wire cutting devices, in particular to a multi-wire cutting device and a multi-wire cutting machine tool. Background Art

[0002] Multi-wire cutting is a new cutting method that uses high-speed reciprocating motion of a metal wire to bring abrasives into the semiconductor processing area for grinding, and cuts hard and brittle materials such as semiconductors into hundreds of thin slices at a time.

[0003] In the prior art, the multi-wire cutting machine with announcement number CN219855380U adopts a scheme of "including a frame, a lifting mechanism arranged in the frame, a bearing platform arranged horizontally on the lifting mechanism, and a cutting mechanism arranged on the frame above the bearing platform, a storage platform is arranged above the bearing platform, and support plates in a vertical upward state are arranged between the two sides of the bottom end of the storage platform and the upper surface of the storage platform, a workpiece to be cut is arranged on the storage platform, a clamping drive mechanism is arranged on the bearing platform between the two support plates, two clamping assemblies are arranged on the clamping drive mechanism for transmission, and the clamping drive mechanism drives the two clamping assemblies to approach or move away from each other, so that the two clamping assemblies respectively collide with the front and rear end surfaces of the workpiece to be cut". This scheme can effectively fix the workpiece to be cut and prevent the workpiece from being offset during cutting. It has high cutting accuracy, simple operation, no need for post-processing, and higher work efficiency.

On the one hand, the higher temperature will affect the service life of the cutting wire. On the other hand, the higher temperature will easily affect the internal structure of the workpiece, thereby affecting the quality of the workpiece after cutting.
