石油管螺纹刀具的使用
The use of carbide threading tools for oil pipes
(1) 影响石油管螺纹加工质量和刀具切削性
能的三要素
(a) 刀具本身的外部要素。包含：
① 刀具结构设计的合理性；
② 刀片刃面及齿形精度、光洁度及表层组织状况；
③ 刀片刃口强化质量；
④ 刀杆制造精度及附件如断屑器等的质量。
(b) 刀片本身的内在要素。主要包含：
① 刀片基体材料质量与性能；
② 刀片表面涂层质量与性能；
③ 刀杆材质及热处理性能。
(c) 刀片的使用要素。主要包含：
① 刀具的正确选择和使用；
② 螺纹加工设备状况；
③ 切削冷却方式及效果；
④ 被加工材料的可加工性及材质均匀性；
⑤ 螺纹加工切削规范的正确选择。
要素 (a)、(b) 取决于刀具生产者单位，要素 (c) 取决于
刀具使用者单位。刀具合理使用的重要性可见一斑。
(2) 石油管螺纹加工的两种方式
第一种：螺纹车削方式：( 油、套管及钻杆螺纹加工均采用 )
其切削运动的特点为：
◇工件 ( 管体或接箍、接头 ) 作旋转运动。产生切削主运动。
◇刀具 ( 螺纹刀具及拔荒刀 ) 作沿锥螺纹母线方向的走
刀运动及间断的吃刀。
◇ 螺纹车削方式为最广泛应用的石油管螺纹加工方式。
其中有单个刀片切削及成组刀片 ( 一般为二片刀 ) 配合组合
刀具切削二种，视具体生产条件及车丝机而定。钻杆接头螺
纹加工全部采用单刀螺纹车削方式。
第二种：螺纹切头加工方式：( 仅油、套管螺纹加工采用 )
其切削运动的特点为：
◇工件(管体或接箍)在切削加工时被定位装夹牢固及静止。
◇刀具 ( 螺纹刀具及拔荒刀 ) 作绕工件轴线旋转的切削主
运动及同时作沿锥螺纹母线方向的走刀运动及间断的吃刀。
◇ 螺纹切头加工方式分为外切头及内切头两种。适用于
大量生产油管、套管及其接箍的加工，生产效率高。外切头
一般含三片刀片的成组螺纹刀片及成组的拔荒刀，内切头含
一片螺纹刀片及多片拔荒刀片等。
(1) Three factors of affecting the machining quality of carbide
threading tools for oil pipes and tool machinability.
(a) External factors of the tools, including:
① Rationality of the design of the tool structure;
② Blade face, the profile accuracy, degree of finish and the condition of
surface structure;
③ Enforcing quality of cutting edge;
④ Manufacturing accuracy of the rod and the quality of the accessories,
such as break chips.
(b) Internal factors of the inserts, including:
① Quality and performance of the base material of inserts;
② Quality and performance of the top coating of inserts;
③ Materials, performance of the heat treatment of tool rods.
(c) Use factors of tools, including:
① Correct choice and use of tools;
② The statue of thread processing equipment;
③ Mode and effect of cutting cooling;
④ Workability and homogeneity of the machined materials;
⑤ Correct choice for cutting specification of thread processing.
(a) (b) depended on tools manufacturer, (c) depended on tools user.
Reasonably using tools is very important.
(2) Two processing mode of carbide threading tools for oil pipes.
Mode of threading (used to process thread oil pipes, casing pipes and
boring rod).The features of the cutting movement:
◇ Rotational movement of the work pieces (pipes or connectors). The
principle cutting movement is occurred.
◇ Movements and intermittent bites while the tools (threading and
roughing tools) move along the generatrix of taper thread.
◇ Threading is used as the most widely way of processing the thread of
oil pipes. According to the production conditions and threading machine,
there are two ways: single insert threading and packaged inserts (two
blades in general) threading with tools units. All the drill rod connectors
are threaded by single insert threading.
Mode of processing threading head (only used to process thread oil
pipes, casing pipes).The features of the cutting movement:
◇ Work pieces (pipes or connectors) are positioned and clamped firmly.
◇ And still movements and intermittent bites while the tools (threading
and roughing tools) rotate around the work pieces axis and move along
the generatrix of taper thread.
◇ The ways for processing are internal cropping and external cropping.
They are fit for producing oil pipes, tubing and processing connectors
efficiently in large number. External cropping contains packaged
threading inserts (three blades in general) and roughing tools units;
internal cropping contains single insert threading insert and packaged
blades in roughing tools units.

效率及刀具寿命十分重要。单齿刀片 ( 如钻杆接头刀片 ) 存在设
计不同进给及吃刀方式决定每次切削行程的切削图形问题，而
不由刀齿齿形结构决定。
(1) 一次走刀行程完成全螺纹切削的情况：
在机床功率及刚性足够大时，以一次行程完成全螺纹切削
的方案为最佳方案，即可以显著提高效率，又可最为合理设计
切削图形，提高螺纹刀片寿命。必须注意，无论是一次走刀行
程还是多次行程完成全螺纹切削的螺纹刀片，其最后一个精车
齿即为保证螺纹精度的齿形，必须覆盖全螺纹牙形并在各部位
均含有合理切削余量。( 两齿侧为 0.07-0.12mm. 齿底齿顶为
0.10-0.20mm)

(2) 多次走刀行程完成全螺纹切削的情况：
在车丝机功率及刚性不能满足一次走刀行程完成全螺纹切
削的情况下只能采取多次走刀行程来完成。此时，第一次行程
(2) Threading inserts of drill rod(processing in threaded turning):
Type Ⅰ : ordinary
Type Ⅱ : ordinary
Type Ⅲ : mainly used on external and internal thread for tool joint
below 3 1/2”.
(5) Cutting figures of carbide threading inserts
for oil pipe
The right design of teeth structure and load will progress the
quality and efficiency of carbide threading inserts, also will
increase the service life of inserts. The different feed ways will
decide the cutting figures of single teeth insert (e.g. drill rod
connector insert),but not decided by the teeth structure.
(1) Thread cutting condition of one time feeding:
If the power and stiffness of threading machine is enough large,
finish the thread cutting by the one time feeding will be the most
favorable alternatives. Which will increase the efficiency and
design the cutting figures more reasonable, increasing the service
life of inserts. Notes: no matter the threading insert finish thread
cutting by one time feed or repeatedly feed, the last fine teeth
must wholly cover the threading teeth and ensure the chipping
allowance is reasonable(the side tooth is 0.07-0.12mm,tooth top
and tooth bottom is0.10-0.20mm).
e.g. 1: The cutting figures of internal round threading of B8N2-3
casing connector. (D-3)
e.g. 2: The cutting figures of internal buttress threading of
P5BN1-5 casing connector. (D-4)
(6)\"Double circular-arc\" structure of refined
bottom tooth of carbide threading inserts for
oil pipe
As the table D-5, the round threading inserts of tubing, casing
and the connector, with the \"double circular-arc\" structure
on the refined bottom tooth , i.e.R1, R2, R2 ≈ R1+(0.2~0.3),
(R1=0.508mm or 0.432mm) will help to avoid the flaws of \"plat

应切除主要的余最，( 特别是对 3 个齿以上的刀片 )，故螺纹刀
片切削图形设计以第一次行程的分配作为依据。随后的行程对
各粗车齿而言，切削 t 都是较小的。

(6) 石油油管套管圆螺纹刀片精车齿底的“双圆
弧”结构
如图 D-5 所示，石油油管及套管和其接箍加工的圆螺纹刀片，
在精车齿两侧齿底处采用“双圆弧”结构，即 :R1 与 R2 二个圆
弧段，且 R2 ≈ R1+ (0.2~0.3)，(R1 为 0.508mm 或 0.432mm)，
实践证明，可避免工件螺纹齿顶出现“小平顶扣”及齿顶“对接”
划道等缺陷。

(7)Several types of flute and chip breaker of
carbide threading inserts for oil pipe
D-6 four type groove and chipbreaker structure for threading
inserts.
The chip breaking is one of the difficult in oil pipe threading
cutting, specially for the finishing tooth. Above structure will
improve chip issuing and breaking partly.
(8)The several forms of oil pipe thread blade
clamping structure and cutter arbor structure
The cutter arbor is a connecting part between the blade and
the cutter holder(or tool apron),which must have sufficient
strength,rigidity and a precision.
The head of cutter arbor is part that is clamping the blade;
the stem is part that is installed into the cutter holder (or tool
apron).
The structure of the head of arbor , namely , part of clamping
the blade, is mainly determined according to the blade shape.
It requests not only sufficient strength and rigidity, but also
requests that the rigidity of clamping blade, the position's
accuracy and reliability, the ease of use and the chip removal
the chip-breaking are ensured.
The different structures and shapes of the blades have
corresponding clamping structures, it can be found in the typelabeling instructions for the oil pipe thread cutter shank of
cemented carbide.
The up-packing type (the structure of M and C) is the clamping
structure of no hole square-shaped blade (or fanshaped blade),
which is used mostly for processing the joint internal threads
of oil pipes and casings. The screw of hook-shaped nut with
the left thread and right thread at the both ends play the role of
pressuring plate that is clamping the blade and the guide chip
plate tightly.

必须指出，石油管螺纹加工中的断屑问题是当今的技术难
题之一，且在多齿的刀片上优甚，特别是精车齿的断屑最为困难。
上述刀片槽形及断屑器结构可对排屑及卷屑状况以明显改善，

(8) 石油管螺纹刀片装夹结构及刀杆结构的几种
形式
刀杆是介于刀片和刀架 ( 或刀座 ) 之间的连接部分。应具有
足够的强度、硬度和精度。
刀杆头部是装夹刀片的部分，柄部是装入刀架 ( 或刀座 ) 的
部分。
刀杆头部即装夹刀片部分的结构主要是依据刀片形状而确
定的。除要求本身具有足够强度和刚性外，还要保证装夹刀片

The draw-in type of inclined pulling rod (the P structure) is a
draw-in type champing structure with a double tapered-hole
blade, which has a two-way clamping effect. The precision
needed of the tapered hole of blade should be guaranteed.
It is characterized by compact structure, reliable positioning
and higher blade material utilization rate. The blades (double
tapered-hole blades) of oil pipes, casings and drilling stems and
others are all suitable for use.
The two-way clamping structure with core rod pressuring plate
slope(the J structure) is mainly used for the clamping between
the drilling stem joint thread blade and the triangle straight hole
cutter of oil pipe thread of sucker rod assembly.
The wedge slope lateral clamping (the F structure) is used
for the clamping structure of long prismoid strip, noncoated,
regrinding-type blades, which is used in processing the external
threads of oil pipe, casing body, with features of clamping firm
and multiple usage by re-grinding along the cutter edge surface
after the cutter edge abrasion, the blade center height can be
adjusted as required when using.
The lateral clamping of standing mounted blade (the G
structure) is mainly used for the clamping structure of the
standing mounted triangular indexable buttress casing thread
single-tooth blade. It is good at its blade strength and rigidity,
with features of clamping firm. This structure has clamping
in the two directions of upward pressure and lateral pressure
respectively.
The arbor's shank is mounted into the cutter holder (tool
apron), the average arbor shank section is square or rectangular.
In some CNC threading lathe for processing the internal thread,
the shank section is round shape. The arbor shank size should
ensure the arbor shank of sufficient strength and rigidity
requirements, and ensure that the ending length of arbor head
should be short as much an possible to prevent the generation
of cutting vibration and thread surface ripple.
In most cases, the arbor shank and head is an integral structure
, but there is also a modular assembly structure that the head
and shank is separated from each other, which is mainly used

的刚性、定位可靠性准确性、使用方便以及排屑断屑等要求。
不同结构形状的刀片有相应的装夹结构。可参见硬质合金
石油管螺纹刀杆型号标注说明。
上压式 ((M 及 C 结构 ) 为不带孔的四方形刀片 ( 或扇形刀片 )
的装夹结构。大多用于加工油、套管接箍内螺纹。勾形螺母的
螺钉两端各带左、右螺纹并起压板作用将刀片及导屑板夹紧。
斜拉杆内拉式 ((P 结构 ) 为带双锥孔刀片的内拉式夹紧结构。
具有双向夹紧作用。刀片双锥孔应保证需要的精度。结构紧凑、
定位可靠、刀片材料利用率高等是其特点。油、套管及钻杆等
刀片 ( 双锥孔刀片 ) 均适用。
带芯杆压板斜面双向夹紧结构 ((J 结构 ) 主要用在钻杆接头
螺纹刀片及抽油杆部件油管螺纹的三角形直孔刀片的夹紧。
楔块斜面侧面夹紧 (F 结构 ) 用于梭体长条形非涂层可重磨
式刀片的装夹结构。使用在油、套管管体外螺纹加工，夹紧牢固，
刀刃磨损后可沿前刃面进行重磨以多次使用。使用时刀刃中心
高可根据需要进行调整。
立装刀片侧面压紧 (G 结构 ) 主要用于立装三角形可转位偏
梯形套管螺纹单齿刀片的装夹结构。刀片强度及刚性较好，夹
紧牢固是其特点。此结构在上压及侧压两个方向分别加以夹固。
刀杆的柄部装入刀架 ( 或刀座 ) 内，一般的刀杆柄部截面为
方形或长方形。在某些加工内螺纹的数控车丝机上，柄部截面
为圆形。柄部尺寸应保证刀杆具有足够的强度和刚性的要求，
井使刀杆头部伸出长度应尽可能小，以防止产生切削振动及螺
纹表面波纹。
大多数情况下，刀杆柄部和头部为整体结构，但也有将头
部及柄部分离的模块式拼装结构，主要在内螺纹刀杆上使用，
如图 D-7 所示。头部损坏时，只需要更换头部，不要更换整个
刀杆。
图 D-7 TableD-7
为了保持加工螺纹时刀片两侧刃有大致相同的侧刃法向后角，
刀片安装在刀杆上需要倾斜一个角度，其值应等于或接近于螺纹
的螺旋升角。故与螺距及螺纹直径有关。这一倾斜角在刀杆上已
加工出来，大约 0° ~1° 20′之间，分四种档次。故使用者在刀杆选
用时应在管螺纹规格 ( 直径及螺距 ) 确定之后，来选取相应的刀
杆规格。本样本 C-050 页中刀杆标注说明⑥的 A、B、C、D 即表
示适用不同直径管材的刀杆规格。
刀杆及刀杆部件需用优质钢材制造，井进行热处理以保持及
达到要求的硬度及强度，断屑器应由性能良好的硬质合金制造。
刀杆基面及定位面等均应磨削以达到要求的精度。

The use of carbide threading tools for oil pipes
the internal thread arbor, as shown in diagram D-7. When the
head is damaged, we just have to replace for the head, without
need to replace for the entire arbor.
In order to maintain that the two blade edges on both sides
have roughly the same normal relief angle of side cutting edge
when processing the thread, the blade installed in the arbor is
on the need to tilt at an angle; its value should be equal to or
near to the thread helix angle. Therefore, it is associated with
the thread pitch and the thread diameter. The tilt angle has
been processed out of the arbor, between about 0° ~1° 20 ＇，
which are divided into the for sub-grades. Therefore, when the
arbors are chose and used, users should choose the appropriate
arbor sized after the pipe thread sizes(the diameter and the
thread pitch) have been determined. The pipe thread arbor
size(diameter and pitch) is determined, to select the appropriate
arbor size. The A, B, C, D in the cutter arbor labeling instruction
⑥ on page C-050 of this sample book indicate the arbor sizes
applicable to different diameter pipes.
The cutter arbor and the arbor parts are required to be
manufactured from the high-quality steel. And they should be
heat-treated to maintain and achieve the required hardness
and strength; the chip breaker should be made of the cemented
carbide. The arbor basal face and positioning surface etc. Shall
be grinded so as to achieve the required accuracy.

(10) 石油管螺纹刀具使用中应注意的
若干问题
(1) 使用前，使用者应了解刀具结构，加工要求
及使用要求。
(2) 刀杆必须正确牢固装夹在刀架 ( 或刀座 )
上。安装前，刀架及刀杆基面应擦拭干净。普通
车丝机的刀杆柄部基面应采用百分表进行找正，
使之平行或垂直于螺纹轴线方向。找正误差应在
0.015mm/100mm 之内。否则将引起螺纹牙形误差，
甚至超差。
(3) 螺纹刀片应正确安装到刀杆的刀片槽内。用
手将刀片侧边定位面靠牢，然后拧紧夹紧螺钉。刀
片定位应正确可靠，夹紧牢固。夹紧螺钉或其他夹
紧另件以及断屑器等如有损坏应及时更换，以免在
切削时损坏螺纹刀片。每次换刀片时，刀杆上的刀
片槽及刀片各基面均应擦拭干净，不得有碎屑夹入，
否则会影响定位精度或把刀片夹碎。
(4) 机床锥度板一定要调整准确，尽量减少加工
螺纹锥度误差。
(5) 根据不同螺纹直径和螺距大小，螺纹刀杆上
的刀片槽底面具有不同的刃倾角，以适应螺旋升角
的变化需要，改善刀片侧后角状况，使用者在选用
刀杆时应加以注意。
(6) 在加工过程中，应随时注意螺纹表面状态、
刀片刃口状态及车丝机运转状态，以便及时调整操
作，保持加工正常进行。螺纹表面缺陷最常见的是
波纹和划道，影响其出现的因素较多，有螺纹刀片
方面的，有机床方面的等。划道的出现可能由于 :
或因刀刃的光洁度，或因刀刃有微小崩刃及缺口，
或因刀刃上粘有积屑瘤或因切屑缠绕刮伤所致。精
车齿齿底圆弧在一侧为全圆弧者最易出现“对接”
划道 ( 指油、套管圆螺纹 )。加工螺纹时，吃刀深
度不够以致未能加工完拔荒的余量则在螺纹牙顶会
出现明显划道。机床系统刚性差时易在管端处几扣
出现牙顶划道 ( 刀片切削时 )。螺纹表面的波纹系
因系统的振动引起，可能由于：系统刚度较差、机
床功率不够，或由于刀刃过于锋利 ( 如非涂层刀片

The use of carbide threading tools for oil pipes
(10) A number of issues that should be noticed in using oil
pie thread cutting tool
(1) Before using it, the user should be aware of the tool structure, processing
requests and operating requirements.
(2) The arbor must be correctly and securely clamped onto the cutter holder(or
tool apron). Before installation, the tool holder and arbor base surface should be
wiped clean. The arbor shank base surface of general threading machine should
be aligned by using a dial indicator to make it parallel or perpendicular to the
screw axis. The alignment error should be within the 0.015mm/100mm. Other
wise the error of thread form will be caused and even beyond the tolerance.
(3) The thread blade should be installed correctly onto the blade slot of arbor.
The side positioning faces of the blade are pushed by hand firmly, and then
tightening the clamp screw. The positioning of blade should be accurate and
reliable, clamping firm. The clamping screw or other clamping components and
chip breaker etc should be replaced in time if any damage to avoid damage in
the thread blades when cutting. Each time when the blade being changed, the
blade slot of arbor and all the basal surfaces of the blade should be wiped clean,
not allowing any chips being.
(4) The lathe tapered plate must be accurately adjusted to minimize the
processing thread taper error.
(5) According to the different thread diameters and the thread pitch sizes, the
bottom surfaces of the blade slot on the thread arbor have different blade edge
tilt angles to accommodate the change requirements of helix angle, improving
the situation in the lateral rear angle of the blade, the user should pay attention
to it in the selection of cutter arbors.
(6) In the process, we should always pay attention to the thread surface condition,
the blade edge status and the threading machine operating state, in order to
adjust operations at any time to maintain the normal process. The most common
thread surface defects are corrugated and scuffing, the factors that result in their
occurrences are many, some in the thread blades aspect, and another in the lathe
aspect and so on. The scuffing occurrence may be due to the causes that: either the
finish degree of blade, or tiny edge chippings and notches in the blade, or the chip
built up sticking with the blade or the scratch wound caused by the chip. It is the
most vulnerable to a ‘docking” scuffing occurrence(refer to oil pipe, busing round
thread) that the circular arc of finish turning teeth bottom at one side is a whole
circular arc. In processing the thread, the depth of cutis not enough so that it fails
to process the complete allowance of rough machining, therefore the clear scuffing
would occur on the top of thread. If the rigidity of machine tool system is poor, it is
easy that the scuffing occurs on the top of several teeth at the ending of pipe(when
the blade is cutting). The ripple on the thread surface was due to the vibration of the
system. And it is likely to cause ripples that: either the poorer stiffness of system, the

查中的齿高及齿形角出现超差者，通常与刀片的
齿形精度有关。必须检查刀片齿形精度或更换新
的刀片。精车齿刀尖若产生，塌尖护现象易引起
齿高增大超差。刀尖磨损易引起齿高减小而超差。
相应地也会影响齿形角的变化。其他螺纹参数如
螺距、锥度、紧密距等产生误差则往往与机床调
整不当有关，需重新调整机床。
(8) 正确的刀片刃口强化对螺纹加工过程至
关重要。涂层螺纹刀片的成品本身在生产厂家已
进行合理的刃口强化工序。其刃口倒圆半径应选
为 R=0.04~0. 06mm 为合适。刀片齿顶及齿底的
倒圆半径应均匀，差值不能过大。非涂层的可重
磨刀片往往在生产厂家未进行过刃口强化。加工
过程中若出现不正常情况 ( 如波纹等 )，操作者
可用小三角油石 ( 碳化硅或金刚石油石 ) 顺着刃
口方向对刀刃进行仔细研磨以实现刃口强化要
求。重磨后的刀片刃口也应如此处理。
(9) 在当前情况下，石油管螺纹加工时必须
进行充分的冷却，仍以供给冷却液的方式为主。
这是提高螺纹加工质量及刀具耐用度的重要因
素。冷却液应正好喷射到刀齿切削部分。有条件
时可用高压冷却液喷射。并在通过刀片前刃面或
底面及断屑器或垫片的小槽将冷却液直接高压喷
射到刀刃切削区域，效果十分明显。且有利于增
加排屑作用。
(10) 刀片的重磨：涂层刀片一般不宜进行重
磨。非涂层刀片一般应进行重磨。重磨时只刃磨
刀片的前刃面，按照原刀片前刃面的方向重磨。
不应当在砂轮机上用手握持刀片或刀杆重磨，
而应当在工具磨床上采用专用夹具重磨。砂轮

machine power is not enough, or because the blade is too sharp(such as the situation
that the edge of non-coated blades is not intensified), or the excessive wear and tear
of blade, or because the system self-oscillation frequency is closer to the frequency of
forced vibration in cutting. If the above scuffing and ripple defects occur, we should
treat them according to the concrete circumstances and causes.
(7) When processing the oil pipe thread, the thread must be inspected for its
precision using a single parameter measurement instrument and the thread gauge.
If it is found that the tooth height and the tooth profile angle is out of tolerance
during the thread parameters examination, it is associated commonly with a tooth
profile precision of the blade. The blade must be checked for the tooth profile
accuracy or replaced with a new blade. If the finish tooth tip has a \"collapse point\"
phenomenon, which can easily lead to that the tooth height is increased and out
of tolerance. Accordingly, it will affect the change of tooth profile angle. The errors
caused by other parameters such as thread pitch, taper degree, thread stand off
and others are often related to the poor adjustment of machine tool, as a result, it is
required to re-adjust the machine.
(8) The right blade cutting edge is essential to strengthen the process of thread
processing. The coated thread blades themselves as finished products have been
conducted with a reasonable cutting edge strengthening process in the manufacturer.
It is more appropriate that the cutting edge rounding radius should be chosen as
R=0.04~0.06mm. The rounding radius on the top and bottom of blade teeth should
be uniform; their difference is not allowed to be too large. The non-coated regrinding
blades tend to be not strengthened on their cutting edges in the manufacturer. If
the abnormal conditions (such as corrugated, etc.) occur in processing, the operator
can use a small triangle whetstone (silicon carbide or diamond whetstone) to make
a careful grinding on the blade edge along the direction of the edge to achieve the
strengthening requirements of cutting edges. The re-grinded insert edge should be
treated as such.
(9) Under the current situation, oil pipe thread must be fully cooled in processing, still
with the coolant supply as the main way. This is the important factor to improve the
quality of the thread processing and the tool life. The coolant should be just sprayed to
the cutting part of the cutter exactly. If possible, high-pressure coolant injection can be
used. And through the front edge surface or bottom of the blade and the chip breaker
or the small slots of pads, the coolant will be jetted directly to the blade cutting area,
the effect is very obvious. Also it helps increase the chip removal effect.
(10) The regrinding of blades: generally the coated blade is not suitable for
regrinding. And generally the non-coated blades should be re-grinded. The
regrinding is only conducted on the front edge surface of the blade n the direction
of the front edge surface of the original blade. The regrinding should not be
implemented on the grinding wheel machine by holding the blade or the arbor
in the hands, but should be carried out in the tool grinding machine by adopting
a special fixture. The grinding wheel size recommended is as below: JR1, particle
size 120#-180#, density75%: SBW100×20×35.

Frequently Asked Questions
产生原因及推荐措施
The causes and the recommend solutions
(1) 切削时产生振动
及波纹
The vibration and
the ripple caused in
cutting
(1) 检查系统刚度是否足够，工件及刀杆伸出量是否太长，主轴轴承是否适当调整、刀片是否夹紧牢固等。
(2) 调低或调高主轴一 ~ 二档转速试加工，选择避免波纹产生的转数。
(3) 对非涂层刀片，若刀刃原来未进行刃口强化，可在现场用细油石轻轻研磨刃口 ( 顺着刃口方向 )。或者在新刃口加工几
个工件后，波纹即能减轻或消除。
Checking that if the rigidity of system is enough, if the exserted length of work-piece or cutting arbor is too long, if the
main shaft bearing is adjusted properly, if the blade is clamped firm and so on.
The spindle speed is reduced or increased by one or two gears for trial processing to choose the revolution can avoid
ripples.
For the non-coated blade, if the cutting edge of blade has never been strengthened originally, now we can use a fine
whetstone to lap gently the cutting edge in the field(along the edge direction). Or we process several work-pieces on
the new cutting edge, then the ripples can be alleviated or eliminated.
(2) 刀片磨损很快，
耐用度很低
The blades wear
quickly, the
durability is short
(1) 检查一下切削用量是否选择太高，特别是切削速度及吃刀深度是否太大。并进行调整。
(2) 是否未供给足够冷却液。
(3) 切削挤住刀刃，引起细微崩刃而增大刀具磨损。
(4) 刀片夹固不牢，或者在切削过程中产生松动。
(5) 刀片本身质量问题。
Checking that if the cutting data selected is too high, especially, if the cutting speed and cutting depth is too large. If
so , the adjustment must be implemented.
The cutting chips wind and break the blade.
The chips jam the blades that lead to tiny crack tipping which increases the cutting-tool wear.
The blade champing is strong or loosing during cutting.
The blade itself has quality problems.

(6) 工件材质不均匀或可加工性很差。
(7) 刀片本身质量问题。
If some scraps or rigid grains have been clamped inside, that leads to cracks or stress during clamping.
The cutting chips wind and break the blade.
The cutting blade comes under accidental collision during blade moving.
The cutter fight of the preorder cutters such as roughing cutters etc, leads to subsequent crack of thread blades.
For the machine tool that retracts its cutters by hand, when retracting for many times, the cutter fights would be
caused by the suddenly increasing load in the cutting edge due to the slow motion of last retracts.
The material quality of work-pieces is not uniform or their machinability is very poor.
The blade itself has quality problems.
(4) 管螺纹齿形误差
超差
The errors of pipe
thread teeth profile
are out of tolerance
(1) 刀片精车齿刀刃已磨损，需更换新的刀片。
(2) 刀片精车齿产生“塌尖”现象，应适当降低切削速度及吃刀深度。
(3) 刀片或刀杆安装不正确。如刀杆安装时未找正基面，刀片基面未靠牢等。
(4) 刀刃上产生微小崩刃，应及时换刀。
(5) 刀刃上产生积屑瘤，应适当提高切削速度，或用细油石轻轻研磨去除积屑瘤，或更换刀片。
The finish turning teeth cutting edge of blade has been worn, and it is needed to be replaced by new one.
The finish turning teeth of blade have a “collapse tip” phenomenon; we should appropriately reduce the cutting
speed and the cutting depth.
The blade or the arbor is installed improperly such as the basal surface fails to be aligned during installing; the basal
surface of blade fails to be leaned against firmly.
The cutting edge has tiny crack tipping , the cutter must be replaces in time.
The blade has some chip build up, to avoid it, we should increase appropriately the cutting speed , or use fine
whetstone to gently lap and remove the buildup, or replace for the blade.
