A multi-wire cutting machine capable of eliminating the influence of cutting wire arc

Abstract

The invention provides a multi-wire sawing machine capable of eliminating arc influence of sawing wires. The multi-wire sawing machine is provided with a grooved pulley assembly, sawing wires, a lifter, a lifting driving mechanism and a worktable; the sawing wires are wound around the pulley assembly to form a sawing wire net, the lower end of the lifter is assembled with the lifting driving mechanism, the worktable is arranged above the lifter, and a workpiece to be sawn is clamped on the worktable. The multi-wire sawing machine is characterized by further comprising a horizontal feed mechanism consistent with the moving direction of the sawing wires; the horizontal feed mechanism is arranged between the lifter and the worktable. The multi-wire sawing machine has the advantages that the position of the workpiece is changed in due time by use of the horizontal feed mechanism, so that the influence of the arc of the sawing wires on the completeness of the cut surface of the workpiece is eliminated, and therefore, the total sawing time of the workpiece is shortened, the production efficiency is improved, and the processing cost of slicing a brittle material is reduced.

Description

technical field [0001] The invention relates to a multi-wire cutting machine, in particular to a multi-wire cutting machine capable of eliminating the influence of cutting wire arcs, and belongs to the technical field of brittle material processing equipment. Background technique [0002] Multi-wire cutting machine is the key equipment in the core device substrate manufacturing process of IC (Integrated Circuit), IT (Information Technology), PV (Photovoltaic) and other industries. Multi-wire cutting is the most advanced slicing processing technology at present. Its principle is that the cutting wire (steel wire) passes through a set of grooved wheels to form a steel wire mesh with different pitches, and uses the high-speed reciprocating motion of the cutting wire to bring the abrasive into the processing area of ​​the material to be cut. Grinding, while the workpiece to be cut is fed through the lifting and lowering of the worktable, so as to realize the innovative slicing p...

AI Technical Summary

Problems solved by technology

[0003] as attached figure 1 , figure 2 As shown, when using a multi-wire cutting machine to slice hard materials, the cutting line 1 will form an arc curve due to the workpiece feed force in the vertical direction (Z direction). In order to ensure that the bottom of the workpiece is completely cut after the cutting operation is completed, the existing multi-wire cutting machine usually adopts the method of increasing the Z-direction feed of the workpiece 2 (attached figure 2 The ΔZ in the method is the increased Z-direction feed), but this brings problems such as long cutting time and low production efficiency, and also increases the processing cost of the product
