specific Embodiment 1

[0036] figure 1 , figure 2 , image 3 and Figure 4 Constitute the specific embodiment 1 of the present invention.

[0037] refer to figure 1 , the present embodiment takes the DK7732 fast-feeding wire-cutting machine tool of Taizhou Dongfang CNC Machine Tool Factory as a carrier, and transforms this machine tool into a middle-feeding wire-cutting machine tool. Through the transformation of machine tool components such as wire storage barrel 1, bed 2, upper and lower cantilever 3, and guide wheel 4, the effect of improving cutting precision and reducing the roughness of the cutting surface is achieved, specifically including the following steps:

[0038] 1) Repair the roundness, cylindricity and straightness of the busbar of the wire storage drum 1

[0039] refer to figure 2 , the dotted line shown is the roundness of the original fast-feeding wire-cutting machine tool. The roundness tolerance is 0.015-0.02mm, which will cause the wire to vibrate. After the wire storag...

Abstract

The invention relates to a medium-speed wire cutting method based on a high-speed wire cutting machine tool, which is characterized in that the high-speed wire cutting machine tool used as a carrier is modified into a medium-speed wire cutting machine tool. The method comprises the following steps: (1) adjusting the cutting precision +/-0.03mm of a high-speed wire cutting machine tool into +/-0.01mm of a medium-speed wire cutting machine tool; (2) adjusting the cutting surface smoothness Ra3.2-1.6 of the high-speed wire cutting machine tool into Ra0.8; (3) adjusting the cutting speed 40-60mm<2>/min of the high-speed wire cutting machine tool into 120mm<2>/min; and (4) modifying the control system of the high-speed wire cutting machine tool into medium-speed wire cutting to form a multiple-time cutting control structure, thereby enhancing the precision and surface smoothness of the machined workpiece. The invention can control the cutting precision within the range of +/-0.01mm, thereby effectively enhancing the cutting precision; and the invention uses an alkaline cutting liquid as the working liquid for the high-speed wire cutting machine tool, thereby reducing the surface roughness of the machined workpiece.

Description

technical field [0001] The invention relates to a method for finishing workpieces, in particular to a medium-feeding wire-cutting method based on a fast-feeding wire machine tool. It belongs to the technical field of mold processing equipment. Background technique [0002] In the prior art, according to the different wire-cutting methods of wire-cutting machine tools, they can be divided into slow-feeding wire-cutting machine tools, medium-feeding wire-cutting machine tools and fast-moving wire-cutting machine tools. The lever pair has pitch compensation and reverse gap compensation, and the cut workpiece has a high finish, but its structure is complex, and the manufacturing cost and use cost are high. Compared with the slow wire cutting machine, the fast wire cutting The static precision technical index is relatively poor, but it has the advantages of simple structure, low cost, and less consumables in the use process. Therefore, it is mass-produced and widely used in Chin...
