Overview of the Mid Speed Wire Cutting Machine Tool

The future of wire cutting machines in China is bright, but the road is also winding. In the current economic and social environment, personnel mobility, quick success and instant benefits, and bosses of all sizes have risen up. Due to the cost of grinding materials, the use of wire cutting to save materials is becoming increasingly significant. Generally speaking, due to tight supply, the use of materials around the world is increasing day by day. This goal can only be achieved by using higher pressure. The report located at 188 Xingtai Road, Taizhou City, Jiangsu Province states that using a company's high-voltage wire cutting technology can save a lot of time. The time for cutting aluminum parts with it can be shortened from 6 minutes to 3 minutes.

Wire cutting processing is a precision oriented job. Although the surface roughness of the wire cutting machine tool has significantly improved, the unilateral discharge of the blade creates more uncertainty in machining accuracy. If it still stays at the original GB7926 standard, the wire cutting machine tool has summarized its shortcomings. In order to promote the healthy development of the wire cutting machine tool, its indicators should be re evaluated to avoid the embarrassing situation of standard but not practical, practical but not standardized. When many cutting technologies appear in the market and China's manufacturing industry is changing rapidly, standardizing the technical indicators that affect wire cutting machines enables the correct and effective application of multiple cutting techniques in the manufacturing industry.

The cutting quality of the workpiece will directly affect the entire cutting process of the circuit. Under normal circumstances, the cutting speed of processed workpieces usually refers to the average cutting speed; Average cutting speed (mm/min)=total cutting area ÷ total cutting time=(cutting length × workpiece thickness) ÷ total cutting time or saving fourth and third cuts. In this way, after cutting and measuring, the shape and size basically meet the requirements. This not only improves production efficiency, but also reduces labor, thereby lowering the manufacturing cost of templates. Today, we will discuss theoretical issues in this area. In fact, we need to do the following to ensure the quality of circuit cutting processing:

Wire cutting water spray plate: The water spray plate must be sprayed well, without tilting or not spraying properly. If the spray is skewed or not sprayed, please check whether the water plate and water valve switch are blocked, and whether the water pipe is tangled or blocked. If the above two situations occur, please promptly clear or replace it, otherwise it will seriously affect the cutting efficiency, smoothness, and accuracy. Screw rod: After running the machine for 6 months, push the screw motor by hand and feel a gap. If that's the case, you can adjust the crescent shaped torch force on the screw pair nut, loosen the two M5 screws on the crescent shape, rotate the pair nut by hand until you push the screw barrel by hand.

Wire cutting processing is usually carried out after hard materials, and carbon tool steel is an optional option because it is difficult to quench and the quenching layer is relatively shallow. Therefore, grinding the quenching layer may lead to a significant decrease in hardness. Therefore, in order to improve the service life and processing accuracy of circuit cutting and molds, we can choose hard alloys as materials, and the hardness from the surface to the center will not significantly decrease. Due to the high hardness of hard alloys, large cutting thickness, slow processing speed, and severe torsional deformation, most of the appearance processing and reserved connection parts (pause points) in CNC wire cutting use a four time cutting method, with the same cutting parameters and offset for both parts. Although compilation technology has met more specification requirements, CNC wire cutting machines can ensure the implementation of each cutting.

We need to improve the mechanical accuracy of wire cutting machines, where the movement accuracy of the worktable and the motion accuracy of the molybdenum wire are closely related to the machining accuracy. Among them, the movement of the workbench is driven by multiple transmission pairs such as gear pairs and screw nut pairs, and their transmission accuracy will affect the accuracy during the machining process. Due to the rotational accuracy of the guide wheel, uneven wear of the guide wheel, and looseness of the molybdenum wire, the motion accuracy of wire cutting is also greatly affected. Therefore, if the precision of mechanical transmission is not high, it will have a significant impact on the quality of intermediate wire cutting processing.
