Parallel gauge blocks in compliance with DIN EN ISO 3650 aresupplied in the following calibration and tolerance grades:

1. Calibration grade -K- for sets of extreme-precision masterstandards and inspection gauge sets determining the sizes of thegauge blocks with lower tolerance grades and of gauges, and forsetting testing equipment.

2. Tolerance grade -0- for sets of extreme-precision masterstandards or comparison standards for gauging the inspectiongauge sets.

3. Tolerance grade -1- for inspection gauge sets and productiongauges, on which exceptionally high demands are made(inspection department)

4. Tolerance grade -2- for production gauges.

The permissible divergences and tolerances are in compliance withDIN EN ISO 3650.Reference temperature, at which the gauge blocks' exactdimension is within the permissible limits, is 20°C/68°F.Gauge blocks are supplied preferably with tolerance grade 0, 1 and 2.

Selection of the smallest graduation of a depends on the applicati-on. For example, if the set is intended for checking gauges, werecommend a set permitting graduations of one-thousandth of amillimeter. Please take advantage of our gauge block service. We cancheck your gauge block sets in a very short time. Afterchecking you will receive a test certificate and a cost estimatefor the gauge blocks to be replaced.

The ISO System of Fits

The system of fits forms the base for exchangeablemanufacture in Industry. In Germany, the DIN system of fitswas introduced in 1923, the ISA system in 1938, and theISO system in 1962, which has been used ever since.

All the terminology which is mentioned in the DIN 7162,such as: nominal size, actual dimension, manufacturingtolerance, nominal deviation, can be found here. Theadjacent figure A shows how these basic terms relate tothe reference line (1). The position of the tolerance zonesrelative to the reference line is given with plus or minus.

Generally speaking, a distinction is made between twofitting systems:Basic hole (2) and basic shaft (3). Various fits or seatsare obtained by different relative positions of the tolerancezones. In the basic hole system (2) all holes are madewith the nominal size as the minimum, regardless of therequired seat, so that the necessary allowances must betaken into account at the shafts in all cases (figure B).

In the basic shaft system (3), the various allowances areprovided in the holes instead, with the shaft being producedwith the nominal size as the maximum (figure C).

The nature of a fit is defined by specifying how large theclearance or oversize is or should be between shaft andholel (figures D and E).In the system of fits any combinati-on of shafts and holes is possible.

To achieve an economical uniformity when selecting thefits, groups of fits are recommended in DIN 7157 that canbe used for the most frequently recurring cases. Therestriction to a limited number of fits enables the stock ofgauge and tools in a plant to be kept within reasonablelimits.(4) = Clearance fit,(5) = Transition fit,(6) = Interference fit.

The ISO Gauge SystemIn addition to the ISO system of fits, there is the ISO systemof gauges, which is meant to ensure that tolerances arecomplied with. The workpieces can be tested with indica-ting instruments or fixed gauges.A distinction is made between:

Working gauges, designed as limit gauges,and master gauges, monitoring the dimensio-nalaccuracy of the working gauges.

Manufacturing tolerances are specified for the workinggauges and master gauges, and wear limits in addition forthe working gauges. The fixed gauges should if possibleconform to Taylor's principle, which states that the"go" side of a limit gauge should test thecumulative effect of the geometric form being checked as awhole, while the "no-go" side should test thevarious elements of this form. Applied to the cylindricalform, this means that the "go" gauge should testthe entire cylinder and the "no-go" gauge theindividual diameters.

ApplicationThe thread limit gauges in compliance with DIN 2279 allow forflawless testing of exchangeable threads. They work similar tocylindrical limit gauges and inspect for.In compliance with Taylor’s principle, the test should cover the overalleffect of the thread, whereas the test should check that the variousthread elements are within the limits.The thread elements are:1. the major diameter (a),2. the pitch diameter (b),3. the minor diameter (c),4. the thread profile from the thread angle and extent of rounding off,5. the pitch of the screw, stating handedness of thread (right or left)(d) = Ø of nut thread,(e) = Ø of bolt thread,(f) = nut,(g) = bolt.

Testing Internal ThreadsTo test internal threads, thread limit plug gauges are used that haveends which compare the overall effect of the thread with the dimensi-ons of the "go" limits. The manufacturing tolerance of thethread "go" plug gauge has a sufficient allowance forpermissible wear.The 5 thread elements are gauged as follows for:1) A check is not required for the major diameter, since it can not be

larger than allowed by the theoretical edge of the thread profile,and natural wear on the thread cutting tools always ensure that theprofile is rounded to a certain extent at this point.

2) The pitch diameter is checked for with the end of the limit pluggauge.

3) The minor diameter is checked with a limit plug gauge.4) and 5) The thread profile, i.e. thread angle and pitch are checked

in test 2).

Testing Male ThreadsThe overall effect of the male thread is checked with a thread ringgauge, or with a thread limit roller snap gauge, which has thefollowing advantages:

1) Avoidance of lost time due to screwing the ring gauge on and off.2) Little wear due to rolling friction, so longer service life.3) The same gauge can be used for both right and left handed

threads.4) All tolerance classes can be set on the roller snap gauge using the

excentrically aligned rollers on the adjusting end.5) Workpieces clamped between centres can be checked inside the

machine without having to unload them.6) Out-of-roundness in the thread can be detected by checking it in

several planes.

The pitch diameter and the minor diameter, and also the pitch andthread angle, are tested for an overall effect using the rollers of thethread limit roller snap gauge. The pitch and the thread angle arealso checked by observing the set between the gauge rollers and thetest piece. The pitch can be observed simply by applying a gaugeroller externally to the threads.The 5 thread elements are gauged as follows for:1) The major diameter is checked seperately with a limit snap gauge.2) The pitch diameter is checked for by means of the rollers of the

thread limit roller snap gauge. The gauge rollers have truncatedthread flanks and only one or two turns. They must not go overthe test piece due to the gauge’s own weight.

3) The minor diameter cannot be smaller than that permitted by thetheoretical edge of the thread section.

4) and 5) The profile, i.e. thread angle and pitch, is checked in test 2)during the test of the pitch diameter.

Shaft Keyway Gauge Bodies

TypeOnly one gauge body is required for each range ofdiameters. The slides for the respective groovewidths are easily exchangeable. They can be usedfor checking the groove width even without thegauge body, since they double as flat limit gaugeswith plane-parallel measuring faces.

ApplicationFor fast and reliable measurement of the keywaydepth and for and testing of the keyway width. Inaddition, the alignment of the keyway to the shaft orhole axis is checked. In hubs, the keyway can bechecked deep inside the hole in this way. Withoutslides.Suitable are exchangeable slides cat.-no. 32741 -32742.
