● 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

■ Series Table

■ Characteristics

・ Major line up of inserts with a wiper edge for high machining accuracy

Can handle a wide variety of machinery from general production

machinery and pipes to aerospace instruments.

・ Stable chip control utilizing a 3D mold chipbreaker

・ Increased cutting performance through the polishing of the cutting edge

flank for high quality thread machining.

■ 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

① Chose either “right thread” or “left thread” based on the table below.

② Confirm the machining thread “pitch” row.

① Confirm the value that matches the machining thread effective diameter.”② 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.

■ How to Replace Shims

■ About Wiper Edges

■ 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.
