一、刻图法发展简况三十年代初,国外就开始了刻图法的研究,到五十年代已有很大的进展,以塑料片代替玻璃版为刻图片基,设计出多种形式的成套刻图仪器和各种具有不同性能的刻图膜,为刻图法能用于生产创造了必要的条件。如美国的通用刻图仪,瑞士的刻图环;捷克的迴转足刻图三脚架,苏联的小车式刻图仪等。它们的共同性能是使刻针处于垂直和稳定状态,便于刻绘各种线划和符号,除这些主要仪器外,符号缩刻,符号摸片,刻针刻刀的修磨工具也进一步完备。采用合金钢式红宝石等特硬材料制造刻针刻刀,延长了
First, the development of the engraving method In the early 1930s, the study of the engraving method began in foreign countries. By the 1950s, great progress had been made. The plastic film was used instead of the glass plate as the engraving base, and various forms were designed. A set of cutting-edge instrumentation and a variety of patterned films with different properties create the necessary conditions for the engraving method to be used in production. Such as the United States General Mapper, Switzerland’s engraving ring; Czech Republic’s rotary foot tripod, the Soviet car cartographer. Their common performance is to make the cutting needle vertical and stable, easy to draw a variety of line strokes and symbols, in addition to these major instruments, the symbol shrinking, the symbol touch film, carving tool grinding tool is also complete. The use of alloy steel ruby and other special hard materials to manufacture engraving knife, extended
