SEALED IMAGE®

Comparator Charts and ScreensALL CHARTS AND SCREENS FEATURE THE SEALED IMAGE PROCESS

The Sealed-image process was developed to give maximum life to our precision charts andscreens. A thin sheet vinyl plastic is laminated over the artwork, thereby protecting the imagefrom wearing off due to use or cleaning.

The lines on charts are made accurate to their center unless otherwise stated on the chart.Our basic line width is .004" to .005" (.1-.12mm).

Glass screens are used for new or replacement screens for optical comparators. The image iscentered to the OD of the glass to .005". Glass screens are available only for 14", 16", 24" and 30" S-T Industries, Inc./SCHERR-TUMICO optical comparators. Glass screens are recommended when the artwork pattern will be used for all applications.

Plastic overlay charts are recommended when patterns will be changed frequently. Plasticcharts are available in any diameter up to 30" (760mm). The plastic material is dimensionallystable, non-flammable and resistant to oil. To avoid distortion, plastic overlay charts should notbe stored above 140˚F (60˚C).

Cleaning - Clean Sealed-image charts and screens with glass cleaner, soap and water or isopropanol using a soft cotton cloth. Avoid harsh rubbing. Do not use paper towels or coarsecloths and do not use acetone, benzene, lacquer thinner or other strong chemicals, as they willdamage the surface.

To order glass and plastic charts, use this part number format:

74-XXXX- DD MM

Pattern Number Diameter Material(Machine size, Inches) (Glass=25, Plastic=30)

Example: 20X Radius/Grid Glass Screen for 14" Optical Comparator=74-0031-1425

IMPORTANT - When ordering glass replacement screens, please include the model numberand serial number of your optical comparator.

SPECIAL ARTWORK - Custom artwork is available on request. We can combine standard patterns or produce custom artwork scaled from your drawings.

NIST CERTIFICATIONS - Accuracy certifications can be provided at an additional charge.Please request this at the time your order is placed.

Instructions for Reading English Micrometers

Reading to .001"A micrometer is operated by a screw threadhaving 40 threads per inch. One completerevolution of the thimble advances onethread .025" or one line on the barrel scale.

To read a micrometer in thousandths ofand inch, read the visible barrel number witheach additional line representing .025"—then add the reading on the thimble witheach line representing .001".

Illustrated example:.375" + .010" = .385"

Reading to .0001"A micrometer with vernier scale has tendivisions on the barrel which equal ninedivisions on the thimble. Each thimblegraduation equals 1/1,000" and each verniergraduation equals 1/10 of 9/10,000.

To read a micrometer in ten-thousandthsof an inch, read the visible barrel number inthousandths as with an ordinary micrometerwith each additional line representing.025"—then find a line on the vernier scalethat exactly coincides with a thimble line.Add the vernier reading to the barrel’sthousandths, obtaining the actual reading inten-thousandths of an inch.

Illustrated example:.260" + .0005" = .2605"

Instructions for Reading Vernier Calipersand Height Gages

Reading to .01mmThe reading of a metric micrometer with“quick-read” numbers on the barrel sleeve isthe same as reading any other metricmicrometer including a vernier readingmicrometer, hundred line thimble readingmicrometer or a plain .01mm readingmicrometer.

The “quick-read” metric barrels aremarked 25-50mm, 50-75mm, 75-100mm,etc. The last visible number and graduationon the barrel sleeve are used, adding thethimble reading to them.

Illustrated example:44.5mm + .12mm = 44.62mm

Reading to .002mmA metric micrometer with vernier scale hasfive divisions on the sleeve which equal fourdivisions on the thimble. Each thimblegraduation equals 1/50 of .5mm or .01mm;each vernier division is 1/5 of .01mm or.002mm. The difference between a thimbledivision and a vernier division is .002mm.

When the zero lines of the vernier exactlycoincide with thimble lines (Figure 1), thenumber on vernier lines is the differencebetween the vernier line and next thimbleline in .002mm. As the line numbered “4” onvernier coincides with the thimble line, thethimble has moved .004mm.

Using Figure 2, determine millimeters tonearest .01mm as with ordinary metricmicrometer. Then find the line on vernier thatexactly coincides with a thimble line. Theadding of the vernier reading to the .01mmreading results in actual reading to .002 of amillimeter.

Illustrated example:6.13mm + .006mm = 6.136mm

Temperature Conversion

Temperature ConversionUse this table to convert Fahrenheit degrees(F˚) directly to Celsius degrees (C˚) and viceversa. It covers the range of temperaturesused in most hardening, tempering andannealing operations.

F˚ = + 325

Lower, higher and intermediate conversionscan be made by substituting a knownFahrenheit (F˚) or Celsius (C˚) temperaturefigure in either of the following formulas.

C˚ = x 59

C˚ x 9 F˚ – 32
