15、the dimensions of hard material inserts with rounded corners and with a partly cylindrical fixing hole. These inserts are primarily intended to be mounted on turning and boring tools using a countersunk head screw or any other fixing element, such as a pin lock.2 Normative referencesThe following re

16、ferenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

17、for metal removal with defined cutting edges Designation of the main groups and groups of applicationISO 1832, Indexable inserts for cutting tools Designation3 Types of insertsThe types of indexable hard material insert specified in this International Standard are the following: TC: triangular inser

18、ts, with 7 normal clearance; TP: triangular inserts, with 11 normal clearance; SC: square inserts, with 7 normal clearance; SP: square inserts, with 11 normal clearance; CC: rhombic inserts, with 7 normal clearance and 80 included angle; CP: rhombic inserts, with 11 normal clearance and 80 included

19、angle; DC: rhombic inserts, with 7 normal clearance and 55 included angle; VB: rhombic inserts, with 5 normal clearance and 35 included angle; VC: rhombic inserts, with 7 normal clearance and 35 included angle; RC: round inserts, with 7 normal clearance; RP: round inserts, with 11 normal clearance;

20、WC: hexagonal (trigon) inserts, with 7 normal clearance and 80 included angle.Inserts dealt with in this International Standard are standardized with chip breakers on the face (designated by the letter T) and without chip breakers (designated by the letter W).Neither the shape nor the dimensions of

21、chip breakers are standardized. Thus, if necessary, special features shall be explained with a diagram or additional specifications.Tables C.1 to C.4 give the range of sizes for these inserts.Indexable hard material inserts with rounded corners, with partly cylindrical fixing hole Dimensions 5DIN IS

22、O 6987:2014-024 Interchangeability4.1 TolerancesThe indexable hard material inserts which are the subject of this International Standard are provided in tolerance class M and for VC-shape inserts also in tolerance class G in accordance with ISO 1832.The values of tolerance class G are in accordance

23、with ISO 1832 and the values of tolerance class M are given in Annex A.Other tolerances are included in Table 1 for hole dimensions and in Tables 3 to 12 for insert dimensions.4.2 Thickness, s, of inserts with chip breakersThe thickness, s, of inserts with chip breakers is defined as the distance be

24、tween the cutting edge at the corner and the supporting surface of the insert; see Figure 1.Figure 1 Thickness of inserts with chip breakers 4.3 Fixing holeIn order to guarantee interchangeability when mounting the insert by a countersunk head screw having a head taper angle between 40 and 60, the f

25、orm of the hole is partly cylindrical and its dimensions are related to the diameter of the inscribed circle of the insert. Figure 2 and Table 1 give the elements of definition of the fixing hole.The position of point P is given by diameter d2(see Table 1), the distance t, measured from the cutting

26、edge at the corner and dimension c, measured from the upper face.The ranges of dimensions t and c are as follows:0,05 d1 t 0,3 d1and0,15 d1 c 0,3 d1These dimensions take into account three cases: indexable inserts with upper faces below the cutting edges see Figure 2 a); with upper faces on the same

27、 level as the cutting edges see Figure 2 b); with upper faces above the cutting edges see Figure 2 c).The dimensions of t and c shall be satisfied in all three cases.The diameter, d1, of the cylindrical part of the hole is given in Table 1.6DIN ISO 6987:2014-02The part of the profile between d1and P

28、 is left to the manufacturers discretion, but shall satisfy the following requirements: the use of screws with head taper angle, , of between 40 and 60 shall be possible; the angle of the tangent theoretical taper at point P has the value of 65; the distance between the contact line with a screw hav

29、ing a 40 head taper angle and the contact line with a screw having a 60 head taper angle shall be as small as possible.The part of the profile above point P is left to the manufacturers discretion.Figure 2 Fixing holeTable 1 Dimensions of the holeDimensions in millimetresdFor insert shapeT, S, C, D,

32、east, shall be marked on the insert itself (except when this is difficult to carry out on small inserts): symbol of the group of application, or commercial designation of the hard material grade, or both, if possible, on large inserts.6 MeasurementAnnex B indicates the methods of measuring the dimen

33、sion m of the indexable inserts covered by this International Standard.7 Recommended dimensionsThe choice of the more common dimensions is restricted to the values given in Tables 3 to 12. It is strongly recommended that these standard inserts be used wherever possible (first preference). When other

34、 inserts are required, their dimensions shall be selected from the non-shaded areas of Tables C.1 to C.4 (second preference). Inserts having dimensions given in the shaded areas of this table are not recommended.NOTE The m dimensions are calculated using the exact values of the corner radius, r, giv
