[0014] Beneficial effects:

[0015] 1. This utility model provides an internal hole cutting device, which forms a reciprocating loop in the internal hole of a circular workpiece through a cutting wire assembly, instead of a single cutting wire passing through the internal hole. This eliminates the need to cut the cutting wire, pass it through the internal hole, and then reconnect it, avoiding the difficulty in ensuring the strength at the connection point due to cutting and reconnecting the wire. Furthermore, uneven quality at the connection point can cause the diamond wire to vibrate. This device can also improve processing efficiency. Attached Figure Description
