Warranty is void if inspection shows evidence of abuse, misuse or unauthorized repair. Warranty covers only replacement of defective materials. If, for any reason, this unit must be returned to our plant for warranty service, please apply for prior authorization with shipping instructions, and include the following information: Customer Purchase Order Number, Buehler Ltd. Invoice Number and Date, Serial Number, and reason for return. Unpacking Carefully unpack and check contents. If any components are missing or damaged, save the packing list and material and advise the carrier and Buehler®, Ltd. of the discrepancy. Assembly The ISOMErrM Low Speed Saw is shipped fully assembled except for a Diamond Wafering Blade and Dressing Stick which are packed separately in the same box. Three Chucks, Weights, Weight Shaft, Counter-Balance Weight, Balance Weight Shaft, two (2) Allen Wrenches, a Spanner Wrench, and an optional Chuck mounting screw are packed separately in the Lubricant Pan which is accessible via the door on the right panel. (See Accessories) 2 MA111280-11 1113/99 I Figure 1 Installation Location The ISOME"fTM is intended for bench-top placement. Select a convenient location with access to a grounded type electrical receptacle rated for voltage, hertz and phase indicated on the Specification Plate located at the base of the rear panel. Electrical Consult Specification Plate for proper voltage for the unit. All units are equipped with an IEC cord connector . Appropriate cord for country of use is supplied. 3 MA111280-11 1113/99 Blade Installation To install the Blade on the ISOMETTM perform the following steps: 1 Remove Thumb Screw, End Cap Bushing and Outer Flange from Drive Shaft. 2. Install blade on Drive Shaft against Inner Flange relieved surface. 3. Slip on Outer Flange and End Cap Bushing, then hand tighten Thumb Screw to complete installation. Waf ering Bl ade Drive Shaft Outer Flange Thumb Screw Figure 2 Note: Smaller flanges must be employed when the 11-1188 Chuck is used for thin sections, or the 11-1189 Chuck for 1" and 1 114" dia. specimens. If gang-sawing is desired, several Blades may be installed, with appropriate spacers, followed by installation of the Outer Flange, End Cap Bushing and Thumb Screw as previously described. Flanges provide support for the wafering blades. Failure to provide adequate flange support may result in curved cuts and damaged blades. Always select the maximum flange diameter commensurate with the size of the specimen to be cut. Note: Before reinstallation of a Wafering Blade, the End Cap Bushing, Screw and Flanges should be cleaned in a mild detergent solution to remove adherent particles from previous sawing. This will help prevent misalignment of Blade and resultant poor-quality cuts. New Wafering Blades, including the original equipment Blade, must be dressed before making sample cuts. Dressing removes normal smeared matrix metal and exposes the abrasive grain to assure free cutting. New Wafering Blades should be dressed several times and older Blades dressed as required by the properties of the sample material. When cutting metal samples it may be necessary to dress after each cut. 4 MA111280-11 11/3/99 To dress, position the Dressing Stick in the 11-1187 Saddle Chuck and make thin transverse cuts through the Dressing Stick, or use a 11-1196 ISOMETTM Dressing Chuck. (See Accessories) Use of this device permits dressing to be performed without removing a previously fixtured sample. CAUTION - Feeding the Dressing Stick or any sample materials manually into the Blade could result in damage to the Blade. Lubrication The ISOMETTM employs the "drag" principle of lubrication with the lubricant carried to the sample on the periphery of the Blade. ISOCUT® Fluid reduces cutting time and produces superior quality cuts. Its use promotes effective lubrication which allows the diamond particles to cut cleanly. It minimizes Blade loading by the formation of discrete chips and effects their clean release from the Blade and work surface. Fill the Lubricant Pan with 11-1193-032 ISOCUT® Fluid to a level that will immerse Blade approximately 1/4". ISOCUT® Fluid is best for most metals and many non-metals. When the lubricant becomes contaminated with sludge it should be discarded and replaced. To remove Lubricant Pan, lift off Door on right side of Saw, grasp Knob on Slide Lock, pull Slide Lock outward until lock disengages, lower the Lubricant Pan Tray and then swing it outward. This will swing the tray outside the case and permit removal and emptying of Lubricant Pan. Clean Pan and Specimen Basket thoroughly and replace in Tray. With Slide Lock still pulled out, swing Tray inward to stop. Press Slide Lock inward to stop and then, while maintaining light pressure on Slide Lock lift Tray upward until Slide Lock engages. Press Slide Lock tully in to secure Tray. Refill with fresh

Vernier caliper and micrometer computer models using Easy Java Simulation and its pedagogical design features—ideas for augmenting learning with real instruments. Physics Education, 49(5), 493.

The laboratory instruments are the vernier caliper and the micrometer. Three computer model design ideas that complement real equipment are discussed in this article. They are 1) the simple view and associated learning to pen and paper question and the real world, 2) hints, answers, different options of scales and inclusion of zero error and 3) assessment for learning feedback. The initial positive feedback from Singaporean students and educators points to the possibility of these tools being successfully shared and implemented in learning communities, and validated. Educators are encouraged to change the source codes of these computer models to suit their own purposes, licensed creative commons attribution for the benefit of all humankind.

  • MODULE 5 – Measuring Tools
    INTRODUCTION TO MACHINING 2. MEASURING TOOLS AND PROCESSES: In this chapter we will only look at those instruments which would typically be used during and at the end of a fabrication process. Such instruments would be capable of measuring up to 4 decimal places in the inch system and up to 3 decimal places in the metric system. Higher precision is normally not required in shop settings. The discrimination of a measuring instrument is the number of “segments” to which it divides the basic unit of length it is using for measurement. As a rule of thumb: the discrimination of the instrument should be ~10 times finer than the dimension specified. For example if a dimension of 25.5 [mm] is specified, an instrument that is capable of measuring to 0.01 or 0.02 [mm] should be used; if the specified dimension is 25.50 [mm], then the instrument’s discrimination should be 0.001 or 0.002 [mm]. The tools discussed here can be divided into 2 categories: direct measuring tools and indirect measuring or comparator tools. 50 INTRODUCTION TO MACHINING 2.1 Terminology: Accuracy: can have two meanings: it may describe the conformance of a specific dimension with the intended value (e.g.: an end-mill has a specific diameter stamped on its shank; if that value is confirmed by using the appropriate measuring device, then the end-mill diameter is said to be accurate). Accuracy may also refer to the act of measuring: if the machinist uses a steel rule to verify the diameter of the end-mill, then the act of measuring is not accurate.

Founded in 1906 by innovative young engineer, Frank Moore, Moore & Wright has been designing, manufacturing and supplying precision measuring equipment to global industry for over 100 years. With roots fixed firmly in Sheffield, England, the company began by manufacturing a range of calipers, screwdrivers, punches and other engineer’s tools. Following investment from Mrs Wright, a shrewd Sheffield businesswoman, Frank was able to expand the business and further develop his innovative designs. By the mid-nineteen twenties, thanks to the company’s enviable reputation, Moore & Wright was approached by the UK Government to consider manufacturing a range of quality micrometers. It was in this field that Moore & Wright’s status as UK agent for the Swiss Avia range of products and subsequent acquisition of the Avia brand and manufacturing rights, proved invaluable.

With this method, you do not have to reset the system to zero after turning it off and then turning it on. The position information recorded on the scale is read every time. The following three types of absolute encoders are available: electrostatic capacitance model, electromagnetic induction model and model combining the electrostatic capacitance and optical methods. These encoders are widely used in a variety of measuring instruments as the length measuring system that can generate highly reliable measurement data. Advantages: 1. No count error occurs even if you move the slider or spindle extremely rapidly. 2. You do not have to reset the system to zero when turning on the system after turning it off*1.
