Description

Multi-wire cutting machine capable of cutting arcs

technical field

The invention relates to a multi-wire cutting machine.

Background technique

The multi-wire cutting machine is a kind of equipment that cuts the workpiece into thin slices through the high-speed reciprocating motion of the metal wire.

At present, the existing multi-wire cutting machine mainly includes a pay-off roller, a take-up roller, a metal cutting wire, a tensioning mechanism, three or four processing rollers, and a Z-axis (vertical direction) mobile table;

100-500 grooves parallel to each other and equally spaced are evenly distributed on the surface of the processing roller, and the metal wire is wound on the surface of the processing roller and embedded in the grooves. After hundreds of turns of winding, a dense cutting line network parallel to each other and equally spaced is formed between the processing rollers, which forms the working cutting area. Finally, use a take-up roller to recycle the used metal cutting wire. During the processing, the worktable to be cut is pushed to the running cutting wire network through the rising of the Z-axis moving table, and the cutting wire network cuts these crystal blocks into the final required thin wafers.

It can be seen from the above introduction that the current multi-wire cutting machine can cut multiple workpieces at one time, and the efficiency is high. However, there is also an obvious defect. The cut workpiece obtained by the current cutting machine is a flat sheet, which cannot be cut. Obtain workpieces with arcs or special-shaped surfaces.

The metal cutting wire is wound on the surface of the processing rollers and embedded in the grooves on the surface of the processing rollers. The two ends are connected with the take-up and pay-off device, the Z-axis moving table is fixed on the frame between or below the processing rollers, the X-axis moving table is fixed on the upper part of the Z-axis moving table, and the X-axis The upper part of the mobile workbench is provided with a workpiece clamp extending upward to the lower part of the processing surface formed by the processing roller and the metal cutting wire.

The advantages of the present invention are very obvious. Through the coordinated movement of the X-axis movable worktable and the Z-axis movable worktable, the workpiece to be cut also moves synchronously in the direction of the X-axis when it moves upwards, so that the workpiece is cut into an arc. Sheet or special-shaped workpiece. The invention has the advantages of simple structure, convenient operation and high processing precision, and is especially suitable for cutting curved thin wafers required in the electronic field.
