anufacturing method of stereotype matrixes for printing plates // 2369484
FIELD: printing industry.SUBSTANCE: processing is performed either with rotary single-cutter or multi-cutter, with one tool or subsequently with several tools. Cutting edge of the tool of the end part has an inclination of 4 to 45 degrees relative to rotation axis with the supply in the direction of movement of not more than 0.5 of diametre by one turn of the tool. Maximum possible rotation speed of the cutting tool is chosen, which is equal to 20 to 120 thousand rpm.EFFECT: obtaining geometrically accurate qualitative flexoform with high surface cleanliness.5 dwg
