在加工洋灰机钢板法兰盘内孔时,我厂使用90°的合金钢刀,α=6～8°前面磨有圆形卷屑槽;由于合金钢的红硬性较差,加工两个内孔就需34～40分钟,且要有足够的冷却液。为了提高生产效率,青年车工姜洪宽同志,创造出一种强力内孔车刀,如附图。经过长期使用,证明效果良好。现介绍如下:1.刀具材料:刀杆采用 CT45号钢,刀片用 T_5K_(10)和 T_1K 硬质合金。2.切削用量:注:加工时如出带状屑片时可增加走刀量,如断屑时可减小走刀量。3.加工范围:可加工通孔或不通孔,以不通孔最为适宜。孔的长度在70毫米以下,直径在50毫米以上尤其适用。加工通孔时刀尖须刃磨1.5
When processing the inner hole of the steel plate flange of the cement machine, our factory uses a 90 ° alloy steel knife, and the circular crumb groove is ground in front of α = 6 ~ 8 °. Due to the poor red hardness of the alloy steel, It takes 34 to 40 minutes for the hole and enough coolant. In order to improve production efficiency, young mechanic Jiang Hongkuan comrades, to create a powerful inner hole turning tool, as shown in the accompanying drawings. After long-term use, that effect is good. Are introduced as follows: 1. Tool Material: Arbor with CT45 steel blade with T_5K_ (10) and T_1K cemented carbide. 2. Cutting amount: Note: When processing a strip of debris when the amount can increase the amount of walking, such as chip breaking can reduce the amount of walking. 3. Processing range: Machinable or non-through-hole, in order to not the most suitable hole. Hole length of 70 mm below the diameter of 50 mm or more especially applicable. When processing through-hole knife blade sharpening 1.5
