Description

Technical Field

[0001] The utility model relates to the technical field of wire cutting machine equipment, in particular to a polycrystalline diamond cutting device. Background Art

[0002] Polycrystalline diamonds are often considered man-made diamonds, most commonly produced from graphite using a unique directional blasting method. Because they are artificially created, their shapes vary. To ensure aesthetic and uniformity, they are trimmed using wire EDM. Currently, wire EDMs primarily consist of a machine tool, a CNC system, and a high-frequency power supply, effectively handling the cutting of delicate, complex parts.

[0003] When a wire saw is cutting diamonds, a clamp is placed beneath the cutting line. The clamp clamps the diamond. Once the cut is complete, the operator releases the clamp, removes the cut diamond, and places the uncut diamond back into the clamp. However, during this process, the diamond cutting is intermittent and the cutting operation is not continuous. Manually placing and removing the diamond significantly increases the operation time. Furthermore, the cutting line is not stopped during this process, making it easy for operators to accidentally touch the cutting line with their arms, posing a significant safety risk and potential hazard.
