[0002] Multi-wire cutting machines are used in semiconductor manufacturing and photovoltaic industries. These machines primarily employ arc-shaped guide bearings to clamp materials and drive them to rotate back and forth at a certain angle. Each bearing unit is 1 / 6 of a full circle, as described in the November 2018 issue of the journal "Bearings." The precision of the arc-shaped guide bearing is inextricably linked to the cutting quality of the workpiece surface processed by the multi-wire cutting machine. The inner ring of the arc-shaped guide bearing requires multiple processing steps such as grinding, milling, drilling, and turning on the machine tool. Only one ring can be processed at a time, resulting in low processing efficiency. Furthermore, because it is not a full circle, clamping is difficult, leading to low processing efficiency and inconsistent precision. Summary of the Invention

The middle of each of the six outer end faces of the fixing frame is provided with a rectangular groove for mounting the insert. The width of the rectangular groove is greater than the width of the groove on the inner end face of the arc-shaped guide bearing. The six sides of the fixing frame are provided with bolt holes corresponding to the mounting holes on the inner end face of the arc-shaped guide bearing.

[0007] The inlay has a convex cross-section, with the upper part set in a groove on the inner end face of the inner ring of the arc-shaped guide bearing, and the lower part set in a rectangular groove on the fixed frame.
