钻头的分类

钻头的分类上篇文章我们写到开孔器，本期主题我们就是钻头。

钻头的种类也繁多，我们一一分解。

1高速钢麻花钻（HSS TWIST DRILL BIT),这类钻头是我们最常见的钻头，可以打木头、塑料、金属等材质。

2 锥柄钻头（TAPER SHANGK BIT)，这类钻头我们在台钻、钻床上经常看到，经常配合莫式钻夹头使用。

主要加工对象是金属为主，对精度要求很高。

3 支螺钻（AUGER BIT), 头部是一个尖锐的赶锥螺纹，用于木头上钻孔，可以根据工件加工的长度，选择需要的长度，目前本人见到最长为1米。

其柄部主要是六角（HEX)和圆柄(SDS PLUS）。

4 木工钻（WOOD BIT ) ，这类钻头就是小号的支螺钻，头部尖尖，快速定位，钻入木头中。

5 木工扁钻（FLAT BIT ),这类的钻头跟上着很相似，但是难以操作，对新手不友好。

价格很便宜。

6 电锤钻（HAMMERING DRILL BIT ),这类钻头主要钻混泥土和红砖，家庭打孔，放膨胀管，经常使用。

其柄也是分为圆柄和方柄，国外市场基本全是圆柄接头。

购买时候要注意，你的机器是什么款式就行了。

7 冲击钻头（MASORY BIT ),这类钻头跟电锤钻一样的功能，只是他们的配对的机器不一样，常见的手电钻就可以配合使用了。

8 宝塔钻（STEP DRILL BIT)，材质跟麻花钻一样，就是麻花钻的亲哥。

这类的钻头分布的尺寸很多，可以从4mm至32mm都可以攻克，一只钻头顶n支麻花钻作用，减少更换钻头的时间和金钱成本。

9 玻璃钻（GLASS BIT），这类钻头大多数用于玻璃是打孔，但也有消费者拿来打瓷砖。

10 霸王钻(MULTI-FUNCTIONED BIT),这类钻头比较网红，可以打n种材质，包括铁、瓷砖、混凝土、铝材等。

也有很多其他的钻头，比如沉孔钻、沙拉钻、锯齿钻、阶梯钻等等，我们不在这一一说明，感兴趣的小伙伴可以去最近的五金店看看，你会发现很多有趣的东西。

高速钢、白钢、硬质合金钢钻头的区别，加工时钻头材质选用的依据

高速钢、白钢、硬质合金钢钻头的区别，加工时钻头材质选用的依据高速钢介绍：高速钢（HSS）是一种具有高硬度、高耐磨性和高耐热性的工具钢，又称高速工具钢或锋钢，俗称白钢。

高速钢刀具是一种比普通刀具要坚韧，更容易切割的刀具。

高速钢名称的由来：高速钢比碳素工具钢具有更好的韧性、强度、耐热性，切削速度比碳素工具钢（铁碳合金）高很多，因此得名高速钢；而硬质合金刚比高速钢的性能更好，切削速度可以再提高2-3倍。

所以常用的钻头都是高速钢和硬质合金钻头！高速钢与合金钻头关系：首先高速钢钻头属于合金钻头！一般的工具钢也属于合金钢只不过是铁碳合金，高速钢的还分普通高速钢和优质高速钢，因此现在合金钻头一般是指硬质合金钻头。

高速钢钻头在高速切削产生高热情况下(约500℃)仍能保持高的硬度，HRC能在60以上。

硬质合金钻头（一般为钨钢材质）具有硬度高、耐磨、强度和韧性较好、耐热、耐腐蚀等一系列优良性能，特别是它的高硬度和耐磨性，即使在500℃的温度下也基本保持不变，在1000℃时仍有很高的硬度。

高速钢钻头和硬质合金钻头材质介绍：高速钢钻头材质是一种成分复杂的合金钢，含有钨、钼、铬、钒、钴等碳化物形成元素。

合金元素总量达10～25%左右。

它在高速切削产生高热情况下(约500℃)仍能保持高的硬度，HRC能在60以上。

这就是高速钢最主要的特性——红硬性。

而碳素工具钢经淬火和低温回火后，在室温下虽有很高的硬度，但当温度高于200℃时，硬度便急剧下降，在500℃硬度已降到与退火状态相似的程度，完全丧失了切削金属的能力，这就限制了碳素工具钢制作切削工具用。

而高速钢由于红硬性好，弥补了碳素工具钢的致命缺点。

高速钢钻头主要用来制造复杂的薄刃和耐冲击的金属切削刀具，也可制造高温轴承和冷挤压模具等，如车刀、钻头、滚刀、机用锯条及要求高的模具等。

钨钢钻头材质（硬质合金）具有硬度高、耐磨、强度和韧性较好、耐热、耐腐蚀等一系列优良性能，特别是它的高硬度和耐磨性，即使在500℃的温度下也基本保持不变，在1000℃时仍有很高的硬度。

绳索取芯钻具使用说明书[1]

绳索取芯钻具使用说明书一、概述绳索取心钻进又叫不提钻取芯钻进，它的特点是当岩芯装满内管时，不提钻而用绳索打捞器从钻杆内把内管捞取上来获得岩芯。

因其结构简单、钻进效率高、岩（矿）芯采取率高、劳动强度低、钻探成本低等显著优点，而广泛使用。

我厂生产的绳索取芯钻具已确定为“S”系列产品：S59、SJ75、S75、S96。

其具体规格见下表：为使用户更好的掌握这项先进的技术，正确的使用我厂生产的S系列绳索取芯钻具及附属设备工具，充分发挥绳索取芯钻进的优越性，特编此书，以供使用参考。

二、绳索取芯钻具的结构和工作原理目前我国使用的绳索取芯钻具结构和工作原理基本相同。

经过生产实践和不断改进，各种钻具均灵活可靠，效果良好，取芯成功率高。

（一）绳索取芯钻具结构主要由单动双管和打捞器两大部分组成。

双管部分由外管总成和内管总成组成。

而外管总成包括弹卡挡头、弹卡室、扩孔器、外管和金刚石钻头组成。

内管总成包括捞矛头、弹卡、单动组件、报警、调节组件、内管、悬挂扶正及卡芯组件组成。

（二）几个主要机构的功用和动作原理1、捞矛机构需要取芯时，打捞器从钻杆内下放到内管总成上端，打捞钩钩住捞矛（矛头）。

向上提升打捞器，捞矛头通过弹簧销向上提升回收管，迫使弹卡钳收缩，这样使内管总成与外管总成脱离，从而把内管提升上来。

2、弹卡机构即定位机构，主要由弹卡架、弹卡钳、张簧等部件组成。

其作用是使内管座到外管中时，弹卡钳借助张簧的张力而张开，贴在弹卡室的内壁上。

其上端有弹卡挡头的拨叉，带动钻具轴承上部和外管同时旋转，防止弹卡磨损。

3、单动机构钻具的单动主要靠两盘推力轴承来实现。

4、调节机构内外管总成的长度，主要通过调节接头和调节螺母进行调节。

达到卡弹簧座底端与钻头内台阶所要求的间隙（3-4mm），减少岩芯受冲洗机会。

在使用过程中，由于内管零部件尺寸的变化，卡簧座与钻头内台阶的间隙亦随之变化。

为了保证岩矿芯采取率，减少残留岩芯，故应及时调节。

5、悬挂机构在悬挂接头下端有一个可拆卸的悬挂环，内管总成到达外管总成中的预定位置时，悬挂环坐落在座环上。

高速钢HSS

高速钢1. 概述高速钢High Speed Steels又名风钢或锋钢，意思是淬火时即使在空气中冷却也能硬化，并且很锋利。

它是一种成分复杂的合金钢，含有钨、钼、铬、钒、钴等碳化物形成元素。

合金元素总量达10～25%左右。

它在高速切削产生高热情况下(约500℃)仍能保持高的硬度，HRC 能在60以上。

这就是高速钢最主要的特性——红硬性。

而高速钢由于红硬性好，弥补了碳素工具钢的致命缺点，可以用来制造切削工具。

高速钢的热处理工艺较为复杂，必须经过退火、淬火、回火等一系列过程。

退火的目的是消除应力，降低硬度，使显微组织均匀，便于淬火。

退火温度一般为860～880℃。

淬火时由于它的导热性差一般分两阶段进行。

先在800～850℃预热(以免引起大的热应力)，然后迅速加热到淬火温度1190～1290℃（不同牌号实际使用时温度有区别），后油冷或空冷或充气体冷却。

工厂均采用盐炉加热，现真空炉使用也相当广泛。

淬火后因内部组织还保留一部分(约30%)残余奥氏体没有转变成马氏体，影响了高速钢的性能。

为使残余奥氏体转变，进一步提高硬度和耐磨性，一般要进行2～3次回火，回火温度560℃，每次保温1小时。

(1)生产制造方法：通常采用电炉生产，近来曾采用粉末冶金方法生产高速钢，使碳化物呈极细小的颗粒均匀地分布在基体上，提高了使用寿命。

(2)用途：用于制造各种切削工具。

如车刀、钴头、滚刀、机用锯条及要求高的模具等。

2. 主要生产厂我国上钢五厂、河冶科技是生产高速钢的主要生产厂。

3. 主要进口生产国家我国主要从日本、俄罗斯、德国、奥地利、法国、乌克兰、巴西等国进口。

4. 种类有钨系高速钢、钼系高速钢和钴系高速钢三大类。

钨系高速钢有W 18 CR 4 V,钼系高速钢有Ｗ 6 Mo 5 Cr 4 V 2 ，钴系高速钢有Ｗ6Mo 5Cr 4 V 2Co5、Ｗ 2 Mo 9 Cr 4 V Co 8等。

微孔加工方法

微孔加工方法在孔加工过程中，应防止出现孔径扩大、孔直线度过大、工件表面粗拙度差及钻头过快磨损等问题，以防影响钻孔质量和增大加工成本，应尽量保证以下的技术要求 : ①尺寸精度：孔的直径和深度尺寸的精度；②形状精度：孔的圆度、圆柱度及轴线的直线度；③地点精度：孔与孔轴线或孔与外圆轴线的同轴度；孔与孔或孔与其余表面之间的平行度、垂直度等。

同时，还应当考虑以下5个因素:1.孔径、孔深、公差、表面粗拙度、孔的构造；2.工件的构造特色，包含夹持的稳固性、悬伸量和展转性；3.机床的功率、转速冷却液系统和稳固性；4.加工批量；5.加工成本。

深孔加工：一般把长径比 L( 孔深与孔径比 ) 大于 5 的孔称为深孔。

深孔加工比一般孔的加工要困难和复杂，其原由是：1.因为孔深与孔径比较大，刀具细而长、刚性差，所以在钻孔时简单偏斜，产生振动，使得孔的表面粗拙度和尺寸精度不易保证。

2.钻削时排屑困难。

3.热量不易排出，钻头散热条件差，使得刀具磨损加剧，甚至丧失切削能力。

机械钻削加工一、 HSS-E（高性能高速钢）钻头因为长钻头自己的稳固度不好，所以在加工过程中一定采纳较低的切削参数，而 HSS较低的红硬性也要求进一步降低其切削速度。

因此，在深孔加工中，外面的冷却液很难抵达刀具的切削刃上，钻尖处实质进行着干加工，所有这些因素的综合致使了深孔加工需要很长的加工周期。

二、枪钻硬质合金头枪钻能够实现精准而安全的孔加工，即便是在进行超常深孔的加工状况下也是这样。

切削液被加压泵打入钻杆内( 压力约为3MPa-8MPa)，而后流过切削刃，当切削液沿着刀具和零件孔壁间的V形截面空间流出时，将切屑带走。

因为钻杆是空心轴，刚性差，不可以采纳较大的进给量，因今生产效率较低；同时，切屑一定保持小而薄的形状，才能保证被冷却液冲出；别的，因为枪钻加工中高压冷却液的使用，所以要求使用专用机床。

因为枪钻钻杆为非对称形，故其抗扭刚性差，只好传达有限的扭矩，所以枪钻只合用于加工小直径孔的零件。

金刚石绳索取芯钻头的正确使用

金刚石绳索取芯钻头的正确使用【摘要】近年来，随着金刚石绳索取芯技术的普及，金刚石绳索取芯钻头的使用寿命以及使用率就很大程度上的影响了工程的整体收益效益，所以，研究金刚石绳索取芯钻头的正确使用就有了重要的现实意义。

【关键词】金刚石绳索取芯钻头；正确使用一、前言金刚石绳索取芯技术由于钻进效率高等一系列优点，被广泛应用于地质勘探、煤田勘探等场合。

正确的使用金刚石绳索取芯钻头，可以为整个工程节省出很大一部分资金，扩大自己的收益。

所以，如何正确的使用金刚石绳索取芯钻头对很多领域来说，都是一个迫切需要弄明白的问题。

现在大批民营钻探队伍进入钻探行业，但其员工大多缺乏金刚石钻探工具的操作技术。

二、金刚石绳索取芯技术的优越性金刚石钻进技术要求要远远高于硬质合金或牙轮钻进技术。

金刚石运用于钻探．是钻探技术的一次飞跃。

随着金刚石钻头质量和性能的提高以及品种的增多，将岩心钻探中的主要矛盾转移到岩心提取方面。

合理的钻具组合可以大大减少井内事故，提高岩心采取率，降低钻井全角变化率，提高钻月效率。

金刚石取心钻具组合大致可分为三种：单管钻具、普通双管钻具、绳索取心双管钻具。

而绳索取芯钻探技术的开发运用，将这一工作提高到了一个新的水平。

大大降低了辅助时间，减轻了劳动强度。

上世纪七十年代以来，金刚石绳索取心钻进工艺由于其自动化程度高、井内事故少、取芯率及钻进效率高的优势，在煤田勘探及石油勘探施工中得到了迅速的推广。

近十年来，金刚石绳索取芯钻进在煤层气参数井施工中又得到了进一步的发展。

其相对于普通金刚石取芯技术主要有优点如下：1、实现了较大间段不提钻连续取心，显著降低钻进辅助时间，大大提高了生产效率。

当岩心装满或堵塞时，钻具报讯，此时只需将机上主动钻杆提移孔口，用绳索把专用打捞器从钻杆中下入钻杆内，即可将内管连同岩心提出孔外。

然后将空的内管总成投入，实现连续钻进。

而对于普通取心钻进900m深的孔，整个提取岩心过程，一般需用50～70分钟，甚至更多。

四、操作说明：
1．安装方法，安装前请确认电源插头呈断开状，电机开关呈关闭状态。

根据选定的型号参照[安装示例图]所对应的安装图正确安装。

如图所示：
将合适的定位杆插入产品中心孔内※双扁柄如图1所示：将柄端两平面对准钻机主轴上的两喉噻顶丝孔。

用六角扳手拧紧并稍留0.2-0.3mm的空隙，用手轻轻来回转动确认位置准确后用力拧紧顶丝。

※通用柄如图2所示：将柄端小圆点对准主轴指示线往上推，待听到“咔嚓”声即可；※FEIN快速柄如图3所示：将主轴上保险环顺时针旋转到位，将柄端直接插入并小范围旋转直至发出“咔嚓”声即可。

2．定位，在需要钻孔的位置用中心錾打一定位点或用合金针划上“十”字线，以确保孔位置的精度。

注意，用中心錾打定位点时，中心錾必须确保垂直加工工件，以免影响切削料芯的顺利排出。

3．钻孔开始，调好合适的转速，开机前请确保钻机磁座底部干净，先打开磁座开关再打开电机开关，电机运转同时打开冷却液开关，慢慢进给直至切削稳定（深度大约1-2mm左右），再适当用力加速快进给速度，但不可用力过猛。

4．钻孔结束后，关闭电机开关待主轴停止转动后，用铁钩除去缠绕在本体上的铁屑，才可继续作业。

5．在钻孔工作时，如遇到以下情况应注意：
（1）排屑不通畅或铁屑呈粉末状，要检查是否铁屑缠绕过多影响排屑应及时清除，或检查产品切削刃是否磨损钝化应及时更换新的产品。

（2）如发生主轴停止转动，为避免损伤刀刃，请先关闭电机，逆方向回转1mm 左右后再回升电机。

（3）发现圆形料芯不能排出时，请用非金属棒避开刀刃轻轻敲打本体部直至料芯弹出。

（4）在对多重板材上进行钻孔时，每钻穿一层，要除去圆形料芯和缠绕铁屑后再进行工作。

（5）在难加工材料上作业，因产生热量过大，必须使产品充分冷却，从而延长产品使用寿命。
