■ Notes for Machining an Insert

Make the cutting edge so that the rake angle,

back taper, etc. as shown in Fig. 3. When you

have installed an insert into a holder, it becomes

a cutting blade element as shown in Fig. 4.

■ Characteristics

For the grooving insert TGA Type, the SumiTurn B-Groove (BF Type)

with chipbreaker that solves the chip control problem now has a

whole series.

■ Features

● Implements good chip control in a wide range of grooving.

● Traverse machining at the groove base is a countermeasure for chip control

● Expanding from 14 items for snap ring grooving, we have 1.4 mm to 4.5 mm edge widths (for a total of

60 items) in stock.

● From steel and stainless steel to non-ferrous metal, it enables the long tool life of various work materials.

We stock the AC530U with Super ZX coat.

Remarks

When ordering a custom grooving insert, fill out the indicated

items (dimensions, items indicated with an ◯ , etc.) and place

your order at our company’s chain or a vendor location.

(Photocopy this sheet to use.)

Furthermore, for shape of edge Width, blade length, and

grooving insert grades other than those in the table below,

contact your local sales representative (see the appendix).

This sheet corresponds with GWC type (→ F4), GWCS type (→ F5), GWCI type (→ F5) inserts.

This form is applicable to Japan domestic market only

Notes for filling out the sheet

1. The graph above describes a right handed tool for for external diameter use or a left

handed tool for internal diameter use.

(Left handed tools for external diameter use and right handed tools for internal diameter

use are the OPPOSITE of the above graph.)

2. The following two insert sizes are available.

3: Inscribed circle 9.525 mm

4: Inscribed circle 12.70 mm

3. Limitations for dimensions such as edge Width and groove depth are as follows.

(1) Maximum edge width (CW): 4.8 mm

・ Types ① and ④ : CW ≤ 4.8 (Sumturm and B-Groove (BF Type) are 4.5 mm)

・ Type ② : CW + C1 ≤ 4.8 (Sumturm and B-Groove (BF Type) are 4.5 mm)

・ Type ③ : CW + E1 (or C1) + C2 ≤ 4.8 (Sumturm and B-Groove (BFType) are 4.5 mm)

(2) Maximum edge width (CW) ・ insert size “3”: CW ≥ 0.33 mm

・ Insert size “4”: CW ≥ 0.75 mm

(3) Groove depth (CDX) ・ insert size “3”: CDX ≤ 0.8 to CDX ≤ 2.5 mm

(for internal diameter: CDX ≤ 0.8 to CDX ≤ 2.0)

・ Insert size “4”: CDX ≤ 2.0 to CDX ≤ 5.0 mm

(For internal diameter: CDX ≤ 2.0 to CDX ≤ 2.5)

4. Grooving Sumiturn B-Groove (BF type): Limited to insert size 4, grade AC530U

Contact us for shapes.

5. The insert’s standard tolerance is as follows.

Symbol Standard tolerance

CW ±0.025 mm

CDX ±0.05 mm

KAPR1, KAPR2 ±1°

It will be manufactured at standard tolerance if there

are no special instructions.

6. The insert grade is based on the insert grade in

stock with the corresponding part number.

7. For insert types ① , ② and ④ , use holders

according to the edge width CW.

Consult us for Type ③ .
