Our mission at Fisher Metrology is to provide top quality gauges, at competitive prices with the best delivery possible. We represent,and purchase products from premier gaugemakers in the U.S.A. and the European Community. We have visited most of our suppliers'plants and toured their manufacturing facilities and calibration rooms to assess their capabilities. Improvements in the level ofcertification to ISO 17025 (Guide 25) or ISO 9000 are evident. Fisher Metrology has recently implemented ISO 9002 and our QualitySystem Manual is complete.

We have selected our most popular gauge product lines and present them in detail with applicable technical data and illustrations. Wealso represent Alameda Thread Gages, Flexbar Machine, Van Keuren, R.L. Schmitt, Kentucky Gages, Swanson Tool, Piccadilly Precision,Kolb & Baumann, Tru-Thread, Tesa, Southern Gage, Huron Gage Blanks and Threads, Inc.

Our new computer system has greatly enhanced our order entry, purchasing and invoicing capabilities and allows quick access to allrecords. We have added email, a 1-800 fax line and completed our website to make our company more accessible to customers locallyand across Canada.

Service is our #1 priority and customer satisfaction is achieved through:

The roller thread gauge is used moreand more for testing the male thread. With

respect to the ring gauge it has the advantage thatfirstly gauging can be carried out considerably quicker, and secondlyright-handed and left-handed threads can be tested with one and thesame gauge. Beyond that, all grades of one nominal size areadjustable. The roller thread gauge is adjusted with the setting gaugeillustrated below. The corresponding socket-screw wrenches aredelivered with the gauge. The checking process is performed in thesame way as with go and nogo ring gauges. The go rollers must beable to be slide over the male thread; the nogo rollers must not passover the male thread.

Flexible Hole Location Plugs

Roller Thread GaugesThread Calipers

Flexible hole location gauge is slotted at 90° increments to ensurepositive location on the thread flank regardless of hole size. Othercommonly used location plugs must be inserted so that the shoulderis flush with a locating face, resulting in squareness deviationtransferred to centerline measurement.

Made in the U.K., knife edge calipers are an easy way to check externalthreaded components. Available in sizes up to 12” or 300mm, thesecalipers can be set with a master plug or with gauge blocks. Parts still onthe machine can be checked with a go/nogo caliper as opposed to ringgauges which require moving the part from the machine. Frames andanvils are readily available from our gaugemaker and can be set andsealed to any pitch diameter and certified.

Dyer/Schwenk Indicating Plug Bore Gauges

FREEDOM TO CHOOSE

Any mechanical or electronic indicator can be used with these Bore Gauges. We recommend theMahr Mechanical Dial Comparators on page 28.

Special adapters are available to interface all manufacturers’ indicators with protective housingsto these Bore Gauges and the gauge handle accepts 3/8” or 8mm stem indicating units.

THE HIGHEST ACCURACY AND REPEATABILITY

For machine capability studies and SPC, the indicating plug gauge is North America’s leader inGAUGE R AND R performance.

All of these Bore Gauges, small and large, 0.079” thru 4.13” (2.0 - 105mm) are 10% capablewhen measuring high tolerance parts.

AUTOMATIC CENTERING AND NO OPERATOR ERROR

In achieving the highest accuracies, the centering sleeve is made approximately 0.001” or.025mm under the low limit of your minimum bore tolerance. The carbide ball contact pointshoused in the centering sleeve along with the free floating movement permit the highestmeasuring accuracy. The contact balls can be supplied in ruby, ceramic and teflon.

“The Measurement is locked in” and no operator error is possible. A special design at the baseof the centering sleeve creates a snow-plow effect clearing the way for a fast accuratemeasurement.

The spring loaded outward contact pressure along with automatic centering and non tippingmeans no operator error when measuring bores.

TWO POINT CONTACT MEASURING (AND YOU DON’T TIP THE GAGE)

Positive two point outward contact pressure and continuous on-line indication of the measuredvalue, in conjunction with a very small reversal error permit measurement of the following boreirregularities. Measuring deviations in a bore’s shape is accomplished by turning or sliding thegauge up and down in the hole.

Unlike three point contact bore gauges that average a bore’s diameter, the indicating plug’s twopoint contact system permits the measurement of out of round conditions. You will measurebores more precisely and with higher accuracies.

GAUGE R AND R

Because of differences in part measuring application, surface finish and factory temperatures,each customer should perform individual GAUGE R AND R studies with each gauge to determinethe GAUGE R AND R capability of a specific measuring application.

Barcor Chamfer Gages

The BARCOR CHAMFER GAGE is a precision instrument designed specifically to measurethe top (major) diameter of a chamfer, countersink, centre drill, or tapered hole. Merelypress the spring loaded, conically ground, precision 3-blade Gauging Plunger into thechamfer or countersink and instantly read the dial in the .001” or .01mm/.02mm diameterincrements.

The CHAMFER GAGE is a direct reading gauge. No Setting Master (Standard) or look-upchart is required. To “Zero” the gauge or check the setting, press the base of the gaugeagainst any flat ground surface and adjust the dial to read the “Set To” number stamped onthe back.

The CHAMFER GAGE is available in two angular ranges: 0°-90° for angles of 90° or less,and 90°-127° for angles greater than 90° but less than 127°. Models for angles largerthan 127° upon request. The standard BARCOR CHAMFER GAGE is furnished with ahardened Tool Steel Gauging Plunger. Optional Solid Carbide Gauging Plungers with aLIFETIME wear guarantee are also offered. Other options include .0001” reading SuperCHAMFER GAGE, External Models, Micrometer Models, HALF-SIZE© Models, Electronic Modelswith SPC capabilities, NIST (formerly NBS) traceable Setting Masters and Letters ofCertification.

Helios

This measuring system offers extremely high accuracy and is therefore capable of coveringtwo fields of application. The measuring system is a 2” built-in glass scale mounted on themeasuring axis.

INTERNAL AND EXTERNAL MEASUREMENTS ON WORKPIECES UP TO 4”.

The system covers an external measuring range of 4” and thus replaces 4 externalmicrometers, facilitates handling and offers a considerably higher accuracy. This is alsotrue for internal measurements where the UMG 50 replaces several sets of bore gaugesand internal micrometers. By shifting the internal measuring probes the measuring rangefor internal measurements can be displaced at any time. Then e.g. only 2” are calibratedon a setting ring, so a measuring range from e.g. 0.6” to 2.5” is available.

Switching from external to internal measurement is possible at any time without the needto recalibrate the system.

INSPECTION OF MASTERS AND THREAD GAUGES

Measurement of plug gauges from 0 to 4” and ring gauges or setting rings from 0.6” to 4”is possible (on request also from 0.25”). External threads up to 4” can be measured bymeans of the three wire method and 40 oz. measuring force.

HOW TO ORDER CYLINDRICAL PLUG AND RING GAUGES

1. Quantity and Whether Go or No Go Member

2. Exact Diameter of Member

3. Z, Y, X, XX Tolerance

4. Type Material Required - Steel - Hard Chrome - Carbide

5. Type of Gauge: Reversible - Taperlock - Trilock - Progressive

6. Whether Handles are required if Plug

7. Marking Instructions

DIRECTION OF TOLERANCE:

The following will apply to all gauges unless otherwise specified:

GO Cylindrical Plug gauges - Plus tolerance (+)

NO GO Cylindrical Plug gauges - Minus tolerance (-)

Master Cylindrical Plug gauges - Bilateral tolerance (±)

GO Cylindrical Ring gauges - Minus tolerance (-)

NO GO Cylindrical Ring gauges - Plus tolerance (+)

Master Cylindrical Ring gauges - Bilateral tolerance (±)

A rule of thumb regarding tolerances on gauges is to use 10% of the totalmanufacturing tolerance of piece part for gauges, with 1/2 of the 10% tobe applied against the GO and 1/2 of 10% to be applied on NO GO.

Example #1 Part Size =.250 + .002/_.000

GO = .250 NO GO = .252

Total Manufacturing Tolerance = .002

10% of .002 = .0002

1/2 of .0002 = .0001

Class Z Recommended

Example #2 Part Size =.250 + .0005/ - .0000

GO = .250 NO GO = .2505

Total Manufacturing Tolerance = .0005

10% of .0005 = .00005

1/2 of .00005 = .000025
