New technology of sawing machine: a new breakthrough in metal band sawing machine

(1) Machining accuracy is further improved. It adopts advanced frequency conversion motor drive, precise ball screw drive and laser positioning method, equipped with a servo-controlled hydraulic system, and the computer automatically monitors the entire sawing process online. The saw blade speed, feed speed, and clamping force can be achieved Arbitrary setting and optimal combination, thereby improving the machining accuracy of the sawing machine. In addition, the key technical point of metal sawing-high-precision cutting force control has always been the focus of the research of sawing machine technology. The German Behringer sawing machine has solved this problem well. The sawing machine can realize constant sawing force control and ensure the constant cutting rate (cutting area/min) of sawing irregular cross-section profiles. The machining accuracy of this sawing machine is also high. For example, when cutting thick materials, the error of the cutting height per 100mm is only 0.1mm.

　　 (2) Sawing machine processing and scope expansion. Improving sawing efficiency, especially thick material and hard metal sawing efficiency, and avoiding sawing becoming the bottleneck of the entire production line, has been the focus of attention in the field of sawing and sawing machine technology for many years. The German Behringer sawing machine saw a stainless steel cutting rate of 48 cm2/min. The company also designed a sawing machine equipped with two sawing systems, which can simultaneously saw twice on the workpiece, thereby greatly improving production efficiency and improving the economic efficiency of sawing processing.

　　 It is a trend to expand the sawing range. For example, the G42200 sawing machine, the largest band saw in my country, can cut pipes and hollow materials with a diameter of 2m. The German Behringer giant horizontal band sawing machine can saw solid square timber up to 2.5m×2.0m, and the giant vertical band sawing machine can saw plate and bar up to 10m long.

　　 (3) The sawing machine is fully numerically controlled and networked. The cutting process of large workpieces often lasts for several hours. In order to ensure the production conditions of one person and multiple machines, and to improve the accuracy and efficiency of the sawing process, it is imperative to fully CNC the sawing process.

　　Networked production, remote diagnosis and maintenance are the development trends of today's CNC machine tools, and CNC sawing machines are no exception. Networked production can make the sawing process be consistent with other links, improve productivity, and facilitate the unified management of all links. Remote diagnosis and maintenance are the result of economic globalization, and can provide extremely fast equipment maintenance across countries and regions.

　　The new breakthrough of metal band sawing machine makes us look forward to the future of sawing machine~
