NATIONAL FOREWORD

This Indian Standard which is identical with IS0 6462 : 1983 ‘Face milling cutters with indexable inserts - Dimensi,ons’, issued by the International Organization for Standardization (ISO), was adopted by the Bureau of Indian Standards on the recommendation of the Milling Cutters, Saws, Gear Cutting Tool and Broaches Sectional Committee and approval of the Production Engineering Division Council.

The text of the IS0 Standard has been approved as suitable for publication as Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker in the International Standards while in Indian Standards, the current practice is to use point (.) as the decimal marker. ’

In the adopted standard, reference appears to certain International Standards for which Indian Standards also exist. The corresponding Indian Standards which are to be substituted in their place are listed below along with their degree of correspondence for the editions indicated:

1 Scope and field of application

This International Standard lays down the dimensions of face milling cutters with indexable inserts.

The form and dimensions of the inserts are left to the choice of the manufacturer.

The range of outside diameters of these cutters is taken from

IS0 523.

3 Style

Milling cutters with indexable inserts are standardized with cut- ting edge angles 45O, 75” and XP and of the following styles :

- style A with tenon drive and hexagon socket head cap screw, diameter 50, 63, SO and 100 mm;

- style B with tenon drive and cutter retaining screw with interchangeability dimensions according to IS0 2780 of diameter 80, 100 and 125 mm;

- style C mounted on centring arbor having a 7124 taper with interchangeability dimensions according to~lS0 2940/l of diameter 160, 200, 250, 315, 400 and 500 mm.

NOTE - The milling cutter style C, diameter 160 mm may also be used with tenon drive.

IS/IS0 6462 : 1983

4 Definitions 5 Dimensions

4.1 Cutting diameter, D, and cutting height, H

Diameter D and height H of the milling cutter are taken from point P as defined in the figures below.

The values of D and Hand their tolerances, as given in the tables, are related to master inserts with wiper edges, having form and dimensions according to IS0 3365/l and IS0 3365/2. When other inserts are used, Hand D will vary.

4.2 cutting edge angle, x, : Nominal value of the cutting edge angle of the insert.

The effective angle obtained on the workpiece depends on the geometry and the diameter of the milling cutter together with the cutting depth.

5.1 Holes for lifting devices

For milling cutters of diameter D equal to or above 250 mm, threaded holes for lifting devices can be provided at the manufacturer’s option. The number of holes and their position is at the manufacturer’s choice but their minimum dimensions must be as follows :

- for milling cutters where D = 250 or 315 mm, threaded holes Ml2 x 27;

- for milling cutters where D = 400 or 500 mm, threaded

holes Ml6 x 34.

NOTE - National safety regulations must be taken into consideration.
