How to calculate a lead angle
: Thread groove width that has a virtually comparable cylinder diameter to the thread width
: Adjoining thread distance
: Thread movement amount after one revolution
(1 section threads are comparable with the pitch)
:
A corner that forms a right angled flat surface between the thread helix and thread axis
: Lead angle
: Lead
: Number of threads
: Pitch
: Effective thread diameter

Shim Selection
f the pitch is large or the thread diameter is small, the thread lead angle will
beome large and the effective clearance angle will become small.
It is ideal to set the threading insert so the left and right clearance angles are
equal.
In order to do this, it is necessary to choose the correct shim based on the
machining thread pitch and effective diameter using the table below. Shim Selection Procedure
Chose either right thread or left thread based on the table below.
Confirm the machining thread pitch row.
Confirm the value that matches the machining thread effective diameter.
Confirm the part number of shim listed above for the corresponding value. If
it is different from the part number you are currently using, change the shim.
Example: If you re machining a right M16 2.0 thread,
the effective diameter is 14.701 mm, so the
values of a [2.0] mm pitch and [11.4 to 17.4] mm
effective diameter in the table correspond.
Therefore the YE3-1p in the For External
Diameter column is the corresponding shim.

The grooves of the thread are machined while leaving the crest untouched.
(The machined surface from the previous operation remains)
You can machine a thread with different pitch widths with the same insert
In the process before threading, it is necessary to nish the workpiece with
the specied external diameter (or internal diameter)
Sharp threads are easily formed
Thread shapes conforming to the screw specications can be machined.
Only specic thread specications and pitch can be machined.
In order to nish a thread with the wiper edge, a nishing allowance of
0.1mm per side is required.
Sharp thread peaks can be round off.

About Cutting Methods
We recommend modified flank infeed machining as a cutting method for SSTE type and SSTI type.
With this cutting method, chip curl diameter is smaller, it is possible to stabilize chip control, and you can suppress the
trailing edge damage that commonly occurs with radial infeed machining. (We recommend a 1 modified angle)

In general tooling, it is often used where
the thread is at the point of the work. In
this tooling, the cutting edge is at the
point near the guide bush side, and
thus you can reduce the undercut width
marked with an arrow.
It is often used where the thread is at
the middle or back end of the work.
In this tooling, the cutting edge point is
near the back turning side, and thus
you can reduce the undercut width
marked with an arrow.
The left hand holder the cutting edge position can go further from the
guide bush, so you can get a sufficient turning distance.
For the left hand holder, A and B type selections are the opposite of the right hand.
(Guide bush side is B, back turning side is A.)

Apply the insert on the right to the STHI type holder.
If using NIR2000 with a pitch over 1.5mm or NIR3000 with a pitch
over 2.5mm, it is possible to make the rounded blade edge large
enough so it doesn t get in the way of thread accuracy.
Each insert is 3 corner use.
