3 Terms and definitions
For the purposes of this international Standard, the following terms and definitions apply.
For further terms and definitions, see also ISO 286-1. It should be noted that some of the terms are detined In a more restricted sense than in common usage.
3.1
shaft
external feature of a workØece, including features which are not cylindrical
3.2
hole
internal feature of a workpiece, inckiding features which are not cylindrical
3.3
size
number, expressing in a particular unit, the numerical value of a linear dimension
3.3.1
basic size
nominal size
size from which the limits of size are derived by the application of the upper and lower deviations
NOTE The basic size can be a whole number o a demal number, eg. 32 15:8,75:0,5 elc.
3.3.2
actual size
size of a feature, obtained by measurements
3.3.3
limits of size
the two extreme permissible sizes of a feature, between which the actual size should lie, the limits of size being included
3.3.3.1
maximum limit of size greatest permissible size of a feature
3.3.3.2
minimum limit of size smallest permissIe size of a feature
5.5Straight grinding wheels used in sets5.5.1General
In principle, the limit deviations as specified in 5.2 and 5.3 apply respectively to straight grinding wheels which areused in sets. However, additional restrictions as specitied in 5.5.2 and 5.5.3 are to be observed.
5.5.2 Limit deviations Tp of the outside diameter
The actual size of the outside diameters D of the separate grinding wheels shall not deviate by more than 1 mmwithin a grinding wheel set.
5.5.3 Limit deviations Ty of the grinding wheel thickness
For grinding wheel sets with distance rings the limit deviations T, of each separate grinding wheel are ± 0,2 mm.For grinding wheel sets without distance rings, neither the limit deviations Tr of the total thickness nor the limitdeviations Ty of any partial width of several separate grinding wheels shall exceed the values as specified inTable 5.
5.6Cemented or clamped cylinder wheels and disc wheels5.6.1 Types involved
Types 2,35,36 and 37.
The limit deviations and tolerances as specified in 5.6.2 and 5.6.3 apply for surface grinding/side grinding.
5.6.2 Limit deviations Tp of the outside diameter, axial run-out tolerance Tpu and radial run-out tolerance,TRL
The limit deviations T, for the outside diameter, the axial run-out tolerances,Tp_ and the radial run-out tolerances,TnLas specified in Table 10 apply to the standardized nominal outside diameters D.
