SOLID CARBIDE THREAD MILLSThreadBurr

TiAlCN

The advantage with ThreadBurr is that you can thread and deburr in one operation. No additional time for deburring and countersink is needed. The deburring operation is made automatically when thread milling, which gives you the deburring without any extra costs.

There is no disadvantage to use the ThreadBurr, even if you don ́t use the deburring function. ThreadBurr is standard on all thread mills from SmiCut.

l

lLP

To get a nice entry and a burr free thread you need to start out with going to full depth (l) in to the hole before starting the threading operation. The thread length (L) will be the cutting length (l) minus one pitch (P).

Double ThreadBurrIt is possible to get the thread deburred on both sides. For this operation you need to use a special tool as thread length depends on the thickness of the material. Have in mind the following when you order a tool for deburring on both sides.

n The cutting length (l) should be equivalent to the thickness of the material.

ExampleM30x3 thread length 40 mm

40 / 3 = 13,3 Number of pitches13 x 3 = 39,0 mm Cutting length (l)

Through holesYou can always use a standard tool for through holes. Please take in mind you should use a tool as short as possible to get best stability and economy.

Blind HolesWith blind holes it is important to have the correct cutting length (l) on the tool to get the thread deburred. Normally you will find a suitable standard tool. If not, we will cut the tool to the correct length with extremely short delivery time and at a reasonable price. Have in mind the following when you order a tool for blind holes.

n The cutting length (l) should be required thread length (L) plus one pitch (P).n The distance to cut off (c) has to be dividable by the pitch (P).

ExampleM16x1,5 thread length 24 mm Thread Milling with NB1212D29_1.5ISO_AC (L = 29,25 mm)

24 + 1,5 = 25,5 mm Required cutting length (l)29,25 -25,5 = 3,75 mm Maximum cutting off3,75 / 1,5 = 2,5 Number of pitches to cut off2 x 1,5 = 3,0 mm Distance to cut off (c)29,25 - 3,0 = 26,25 mm Cutting length (l) after cutting off26,25 - 1,5 = 24,75 mm Thread length (L) after cutting off

You only need to cut of the tool when you want to use the deburring function on blind holes and if there is no standard tool with suitable cutting length.

THREAD MILLINGAdvantages

Deburring of the thread

n 1) A secure machining operation

Minimal risk for machining stops as the cutting forces are low and the chips are short. Should there be an accident, the work piece will not be destroyed, as the tool will not be caught since the diameter of the thread mill is less than the thread.

n 2) Threading in difficult machined materials

The excellent cutting conditions makes it possible to thread mill materials such as hardened steel up to HRC 65, Titanium and other difficult machined materials.

n 3) Higher thread quality

The cutting conditions are extremely good when you are thread milling. The result of the thread is a higher quality of surface finish, tolerance, angle, etc. compared with other threading methods.

n 4) Flexible tool

Same cutter can be used for right hand and left hand thread. Threads with different diameters can be made with the same tool as long as the pitch is the same. The same thread mill can be used for blind holes and through holes. W, BSPT, PG, NPT, NPTF and NPSF are thread profiles where you can use the same tool for external and internal thread.

n 5) Threading in blind holes

When thread milling you will get a complete thread profile to the bottom of the hole. When tapping it´s necessary to drill much deeper as it´s not until the third thread the tap will make a complete thread profile. Sometimes you are able to change the construction as you don´t have to take the deep hole into consideration.

n 6) Less wear on the machine spindle

Thread milling will give you longer life to the machine spindle compared with tapping as the rotation on the spindle doesn´t need to be stopped and reversed for every thread.

n 7) Energy-saving production

Low energy consumption as the machine spindle doesn´t need to be stopped and started after each thread.

n 8) Thread Milling in a lathe with live tools

Reduced machining time compared with thread turning. Excellent chip control.

n 9) Threading without burrs

The thread entrance will be burr free when using ThreadBurr. Threading and deburring in one operation. No additional time for deburring.

n 10) Shorter machining time

The machining time will be short as you don´t need to chamfer the thread while using ThreadBurr. Big diameters, fine pitches and long holes saves the most time compared with thread tapping.

n 11) Correct Thread Diameter right away

The Pitch diameter has been optically measured on thread mills from SmiCut and the theoretical external diameter has been individually laser marked on each cutter so you will get a correct thread straight away. When the tool starts to wear it´s possible to make adjustments in the CNC-program.

Correct Diameter

How to choose correct Thread Mill Diameter

When thread milling, the diameter of the tool has to be smaller than the thread diameter. The reason for this is that the thread has a helix angle, but the tool is straight. If the tool is too big there will be a deviation on the thread profile. The size of this deviation depends on several parameters.

1) Thread diameter 2) Cutter diameter 3) Profile angle 4) Pitch

Big cutter diameter compared with thread diameter, small profile angle and big pitch. These are parameters that gives bigger deviation.

There are three alternatives too choose correct thread mill diameter.

1) SmiCut Catalogue 2) SmiCut Online Store, www.smicutstore.se (see page 8) 3) SmiProg Software, www.smicut.se (see page 9)

How to get correct Thread Diameter

The pitch diameter has become optically measured on thread mills from SmiCut and the theoretical external diameter has been individually laser market on each cutter. This diameter is what you should use in your program to get a correct diameter on your thread.

For coarse threads you are normally in the middle of the tolerance if you use the laser marked value.

Fine threads may be a little bit tight as you get a very small thread profile deviation on these threads (see above). If this is the case you can mill again after adjusting the diameter in your program.

How to get a burr free Thread

Thread Mills from SmiCut (ThreadBurr) will give you a nice entry and a burr free thread. The cutting length is laser marked on the tool and you can find it as well in the catalogue. This is the distance you should go in to the hole from the surface to get a perfect entry.

ONLINE STORESelect correct Thread Mill

SmiCut Online Store will help you find suitable tools

If you need a Thread Mill for a specific thread and you need help to find the correct tool, just go to www.smicutstore.se and you will very quickly find suitable tools.

Example: M16 with thread length 32 mm

1) Choose THREAD MILLING Application on the left side 2) Choose M - Metric coarse 3) Choose M16 4) Choose what kind of tool you want, for example without coolant

Now you can see all solid carbide thread mills without coolant that are able to produce M16. From these ones you have to take a tool with a cutting length of at least 32 mm. You can see the cutting length on the part number (see next page for more information about ”code key”). The most suitable tool is NB1212D35_2.0ISO_AC. If you want complete information about the dimensions press on the part number of the tool.

You are as well able to do this thread with a tool with a smaller diameter or longer thread length, but this result in longer machining time and/or not as good cutting conditions. Sometimes you choose this anyhow as you may already have the tool, the price is less or you want to have a tool that can make different sizes of threads.

To check machining time and cutting conditions for different tools, please use ”SmiProg” (see next page).

SmiCutTM THREAD DESIGNATIONS M

For coarse threads, the pitch is not written as it is determined of the diameter, for example M16 ins-tead of M16 x 2.

If the tolerance grade and position is the same for pitch and major diameter, it is written only once, for example 6h instead of 6h6h. Small letter for exter-nal threads and capital letter for internal threads. If no tolerance class is written, it means that the tole-rance is 6H/6g. Slash between tolerances provide information about the internal and external thread.

It is not necessary to write RH for right hand thread as almost all threads are right handed.

M16 is a simplified writing of M16 x 2 - 6H/6g - RH.

SmiCutTMTHREAD DESIGNATIONS

When the thread is smaller than 1/4”, the diame-ter is given with a number from No. 0 to No. 12 (No. # x 0.013” + 0.060”).

Mostly, the pitch is not written as it is determined of the diameter for UNC, UNF and UNEF threads.

If no tolerance class is written, it means that the tolerance is 2A for external threads and 2B for internal.

It is not necessary to write RH for right hand th-read as almost all threads are right handed.

1/4 - UNC is a simplified writing of 1/4 - 20 UNC - 2A/2B - RH.

All types and tolerance classes can be produced with W (Whitworth) thread turning and thread milling tools.

R - Whitworth / BSPT (T=tapered) Pipe ThreadAll types and tolerance classes of conical threads can be produced with BSPT threading tools.

To get a pressure tight-joint you need a seal ring between the shoulder of the external thread and the face of the internal thread.

As the thread is conical it will be almost a pressure tight-joint, but to improve the sealing effect you need to use a thread seal tape.
