株洲热熔钻操作说明一、手动进给推荐操作步骤 1. 正确选择热熔钻（孔径和类型） 2. 选用推荐的功率和转速3. 使用推荐的刀柄4. 正确将夹头装入刀柄 5. 将热熔钻钻头装入夹头并锁紧（定期检查和调整刀具的夹紧力） 6. 将刀柄接入钻床 7. 将加工工件紧固在工作台上 8. 确保工件和刀具之间的合适运行范围（正确地设置起始和终止的位置） 9. 正确选择转速 10. 正确选择钻孔深度 11. 按照材料和厚度选用推荐的进给速度12. 加少量润滑油于刀具上 13. 下压手柄，保持规则匀速的进给速度，不可停顿 14. 当钻头底部到达工件表面，迅速放松手柄 15. 注意观察钻孔时间和钻头颜色 16. 注意调节转速和进给速度（步骤9,13），温度过高：降低转速或提高进给速度，或二者安全提示：1. 热熔钻操作过程中需始终配戴安全手套和护目镜2. 在工件没有冷却之前请不要用手直接触摸3. 平口型热熔钻操作时因由有切屑飞出请穿防护服。刀柄和夹头的安装 正确 错误 首先将夹头旋入刀柄螺母,然后再将螺母与刀柄旋接不可将夹头直接装入刀柄钻头的安装正确错误将热熔钻头钻柄部完全插入夹头内不可只将部分钻柄插入夹头注意：平口型热熔钻的操作l 将会产生一小条钻屑，请作好防护。 l 在进行平口型钻头操作过程中，只需在切削开始时，进行瞬间加速进给。瞬间加速进给将会大大延长刀具使用寿命。 l 通过观察钻屑的长度和形状，可以确定操作的准确性。钻屑长而细，错误钻屑短而粗，正确正确进行瞬间加速，将会延长刀具使用寿命二、 热熔钻使用注意事项1. 工件材料：热熔钻适用于加工工件孔径1.8-32mm，壁厚0.512.5mm的多种金属材料，如铁、低碳钢、不锈钢、钛、铝、铜、紫铜、黄铜(Zn含量低于40)、铝合金(si含量低于0.5%)等。如果材料越厚、越硬，热熔钻头使用寿命越短。2. 热熔膏：热熔钻在工作时，瞬间产生600 C以上的高温，特制的润滑膏能延长钻头的使用寿命，改善圆柱体内表面的质量，产生清洁的和令人满意的边缘形状。建议普通碳钢每钻5个孔，加少许润滑膏于刀具上；不锈钢工件，每钻一个孔，需添加润滑膏；材质越厚、越硬，使用频率越高。可以手工涂抹润滑膏，也可以自动喷淋润滑油；因一般油脂无法达到高温，故需使用特别开发的油脂。3. 热熔钻的刀柄和夹头，如果没有专用散热器，可使用压缩空气降温。4. 使用热熔钻对于钻床有同轴精度要求，安装热熔钻时应夹紧钻头，以免钻头不同轴晃动而导致断裂。只要达到合适的转速和功率的各种钻床、铣床和加工中心都适合于热熔钻；与传统的加工工艺相比，热熔钻加工需要更高的转速，孔径的大小、材料的厚度以及材料本身的不同都影响到转速的确定。5. 预制孔：通过预先钻削一个小的起始孔能避免工件变形。预制孔可以减少轴向力，也可以减小圆柱体的高度，还可以在圆柱体的最下端部产生一个光滑的边缘，还可以避免薄壁（小于1.5毫米）工件的弯曲变形。6. 带槽钻尖型热熔钻头（头部带切削刃），推荐用于加工表面涂层的工件材料。因为这种钻尖有助于在钻削加工开始时去除覆盖在工件表面上如油漆、镀锌等任何妨碍钻孔的覆盖层。这个切削刃用来还有助于防止薄壁工件在钻头向下的压力作用下可能产生的变形。带有切削刃的钻头使钻孔变得很轻松，由于切削刃的存在，可适当减小钻孔时的轴向力，适用于：因工件厚度较薄而在钻孔时容易弯曲；硬度较小的材料。7. 在攻丝时，选用攻丝油。可以使用普通切削丝锥，但推荐采用挤压丝锥，这种螺纹不是通过切削而是通过挤压形成的，因此具有较高的拉伸强度和扭矩值。8. 热熔钻的维护保养：热熔钻使用一段时期后，表面会有磨损，刀体上会附和一些热熔膏或工件杂质，为确保加工工件的准确，提高热熔钻的使用寿命，可将热熔钻夹在车床或铣床夹头上，用研磨膏修磨即可，切忌注意安全。四、影响热熔钻寿命的因素9. 尽管热熔钻头机械强度仍可保持在高温下工作，但材料对于热应力仍然敏感，所以必须避免温度急速升高或降低，必要时加风洽，使钻头保持黑红。为了防止主轴温度过高，建议使用特殊散热式夹具。10. 热熔钻不耐震，故不能以尖端快速接触材料，而稳定的加压非常重要。在穿透材料时，需避免挠出的效应发生，压力必须减少很多，否则会造成力量不相称，钨材在此种情况下会产生不均匀疲劳效应。11. 钻床主轴不稳定会造成钻头伤害，不要再钻不完整的孔，因孔已收缩。同一孔因故未完成，不可再行钻孔，必须放弃。 12. 经常润滑钻头自然对工作寿命有利，使用钻石挫刀和砂纸清洁钻头效果很好。 13. 在材料厚时，不妨先做一个导引孔或使用绞式钻头，如此可减少钻头压力。 14. 使用平口型钻头避免铁屑粘在边缘，必需用风吹开及减速50%70%RPM
