4 HARDNE WEAR REITANCE TABILITY ERVICE Gauge Blocks are a high quality product: Our exacting standards are backed by more than 70 years experience and research, resulting in the careful selection of the purest steel which must fulfill our high standard demanded, especially with regard to stability, wear resistance, uniform co-efficient of expansion. The ageing to eliminate internal stresses and stabilizing methods, along with special lapping techniques are some of the many critical considerations we offer to potential users. All gauge blocks and accessory sets are supplied in wooden storage cases, in ingenious easy to select design. The use of gauge block accessories in conjunction with gauge blocks offers the possibility of many measuring and gauging applications. Our accessories are manufactured to the same exacting standard as are our gauge blocks. When we are selected we are confident that our customers are obtaining the very best in materials, workmanship and, most important, value for money. KOLB & We run a DAkk laboratory. Made in Germany 6

As tolerances are kept to a minimum by internal standards, it is guaranteed that every Gauge Block is within the limits stipulated. The high level of accuracy and the reliability of the measuring results are guaranteed by two separate feed-backs attributed to the internationally fixed unit of length by means of a wave length: permanent comparison with the master gauges interferometrically verified by the Physikalisch-Technischen Bundesanstalt, parallel to this calibration in our fully airconditioned laboratories. Laboratory (partial view) Gauge Block Inspection Tolerance ranges of the individual grades within the limits of which the actual size is guaranteed, can be taken from the table above. The durability of gauge blocks is achieved by a special process developed by us, combining natural and artifical ageing. The grade of accuracy should be selected according to the intended purpose. K: Gauge blocks of Grade K are excellently suitable as the most accurate material measure with regard to length, and for checking gauge blocks of lower grades. Gauge blocks of Grade K will be clearly marked with a serial No. They will be supplied with a DAkk-calibration certificate which shows the deviation from the nominal size of each gauge block. 0: Used as master gauges for all accurate measurements of length, for checking all gauge blocks in use, for final inspection, for setting accurate measuring instruments. : For checking of gauges, for setting measuring instruments. 2: Used as standard for setting or workshop gauge for the manufacture of jigs and gauges, as well as for machines and instruments. Upon request we supply a calibration certificate of the Physikalisch- Technische Bundesanstalt, which will be charged separately. In most of the factories the use of only one grade will not do, as the accuracy varies in the individual departments and manufacturing stages. But just this fact implies the efficient use of gauge blocks. Example: If gauge blocks of grade 0 are no longer accurate enough for inspection as a result of frequent use they are passed on to a department or workshop place were the demands on the accuracy are accordingly lower. We recoend, however, to have them inspected at our laboratory before passing on. 8

7 Material pecial teel stable in size, wear resistant teel Gauge Blocks This carefully hardenend and stress relieved steel type which is specially melted resulting in the highest possible degree of purity has a homogeneous molecular distribution which gives excellent properties against abrasion and wear. The wear is well minimized due to the homogenous dispersal of steel elements and thus uniform fine structure of carbide components. A clever method of ageing will remove residual austenite and therefore guarantee smallest possible changes in size even below the IO-standard. Ceramic Ceramic Gauge Blocks The wear behavior of Ceramic Gauge Blocks is similar to that of carbide. The co-efficient of thermal expansion is closer to steel and is (0 ± ) 0 6 K. Ceramic gauge blocks are not subject to corrosion and are therefore excellently suitable for the work shop. The bending strength of 800 N/ 2 is so high that there is no danger of breakage during ordinary use. Our Ceramic Gauge Blocks are available in grades K, 0, and 2. Carbide Carbide Gauge Blocks The wear ratio as compared to that of steel is approx. :0 to :00. Carbide gauge blocks are mainly used as wear protectors as gauge block combination specially wears at the outside measuring faces. All gauge block sets are provided with two empty slots for storing carbide wear protectors, in or 2. Every gauge block from 0, 00 is available of solid tungsten carbide. The material used in these gauge blocks has a co-efficient of thermal expansion, 0 6 K. Carbide gauge blocks are used in workshops and tool rooms under severe wear and abrasion conditions. We wish to stress that steel gauge blocks be used where work pieces of steel have to be checked and a standard reference temperature of exactly 20 C cannot be maintained. Considering the difference of the co-efficient of thermal expansion between steel and carbide, this would lead to a larger uncertainty of measurement. ingle Gauge Blocks from up to 0, 0, 0, 0, 0, 0,,000,00,00,0,,, 2, Graduation Material nominal size 0,0 0,0 0,0 0,00 0,0 0, 0, H H K Material = available in steel Kb = available with Kb = ceramic tips Cross section Rectangular cross section: below 0, 20 /30 0, 0 30 over 0 3 Gauge Blocks over 00 are manufactured with clamping holes at both ends and may also be used with holders of other manufacturers.

15 Gauge Block Accessories are especially designed and manufactured to extend the high degree of gauge block accuracy into the field of fast, accurated temporary gauging, which are used in inspection departments and also in toolroom and machine shops on small batch production to keep gauging costs at a minimum. The range of possibilities is manifold and below are quoted a number of popular examples. Internal cylindrical gauge (instead of plug gauge or cylindrical limit plug gauge) pacing or external gauge (instead of snap gauge or adjustable limit snap gauge) Precision height gauge (instead of height marking instrument) Precision marking compasses etting gauge for bore gauging instruments Master gauges for exact graduations, etc. Examples of Gauge Block Accessories used in conjunction with Gauge Blocks Precision marking compass points etting gauge for bore gauging instruments or inside micrometers go no go Adjustable limit snap gauge Precision height gauge Internal cylindrical limit gauge no go go 7

16 Gauge Block Holders with quick adjustment We developed quick adjusting gauge block holders for use with precision gauge blocks, which are hand made to assure burr free side and fixing surfaces. The rack pattern positive locating groovers provide rapid adjustment and prevent gauge block combination from slipping or moving once in position, thus loading is simple, fast and safe. The clamping slide and gauge block combination are both secured by the same thumb screw, located on the clamping slide. On request the range of holders from may be increased when supplied with special holes and used in conjunction with expanding block No. 20 from 0 up. When ordering please state requirements, e.g Cat.
