Frequently asked questions
Common questions about MITUTOYO from 3G Electric.
What types of Mitutoyo dial indicators does 3G Electric supply?
3G Electric supplies several Mitutoyo dial indicator families, including balanced reading flat back dial indicators and horizontal dial test indicators. Models cover both inch and metric graduations, with measurement ranges such as 0 in to 0.05 in, 0 mm to 1 mm, and 0 mm to 0.2 mm. Accuracies range from 0.0001 in to 0.008 mm, depending on the model. Many indicators feature a flat back for fixture mounting or a back plunger for space-constrained setups. The line includes AGD 1 and AGD 2 sizes, and some models ship with a Certificate of Inspection. These indicators are used for comparative measurements, runout checks, and flatness verification on shafts, surfaces, and machined parts.
What is the purpose of the Mitutoyo surface roughness specimen 178-602CAL?
The Mitutoyo 178-602CAL is a calibrated reference specimen used to verify the accuracy of surface roughness testers. It is made of nickel alloy and has a certified surface roughness of 116µin (2.94µm) Ra. The specimen is used in quality control and metrology labs to confirm that a roughness tester is reading correctly before measuring production parts. It conforms to ISO standards for roughness specimens. Regular verification with a reference specimen helps maintain measurement traceability and supports quality management systems that require periodic checks of inspection equipment. 3G Electric includes this specimen in its Mitutoyo catalog for customers who need to validate their surface roughness measurement processes.
Are Mitutoyo dial indicators available with inch or metric graduations?
Yes, 3G Electric stocks Mitutoyo dial indicators in both inch and metric graduations. Inch models include graduations such as 0.0001 in, 0.0002 in, and 0.0005 in, with ranges like 0 in to 0.025 in, 0 in to 0.05 in, and 0 in to 0.2 in. Metric models offer graduations of 0.002 mm, 0.005 mm, and 0.008 mm, with ranges such as 0 mm to 1 mm. The dial readings may be balanced (e.g., 0-5-0, 0-10-0, 0-20-0, 50-0-50, 0-100-0) or continuous, depending on the model. This allows users to select an indicator that matches their existing measurement system and tolerance requirements.
What is included with Mitutoyo dial indicators from 3G Electric?
Many Mitutoyo dial indicators supplied by 3G Electric include a Certificate of Inspection. This document provides evidence that the instrument has been inspected and meets the manufacturer's accuracy specifications. The certificate typically lists the model, serial number, and measured deviations. Some indicators also come with a fitted case or protective packaging. For specific models, the certificate is part of the standard delivery; for others, it may be available on request. Buyers should check the individual product listing for details on included accessories and documentation. The availability of inspection certificates supports quality systems that require traceability for measuring equipment.
What are the typical applications for Mitutoyo dial test indicators?
Mitutoyo dial test indicators, such as the horizontal model 513-485-10E, are used for comparative measurements of flatness, runout, and alignment. The horizontal style allows the indicator to reach into confined spaces or measure surfaces that are parallel to the mounting axis. With a measuring range of 0 mm to 0.2 mm and a resolution of 4 µm, these indicators are suitable for checking small deviations on shafts, bores, and machined faces. They are commonly used in machine setup, inspection, and quality control. The 513-485-10E includes a Certificate of Inspection. 3G Electric supplies this and other dial test indicators for metrology and production environments.
Does 3G Electric offer Mitutoyo centering punch sets?
Yes, 3G Electric includes the Mitutoyo center punch set (MPN 985-138) in its catalog. This is a 5-piece set with tip sizes ranging from 1/16 in to 5/32 in and overall lengths from 3 in to 4 in. The punches feature a knurled grip for secure handling and come in a pouch for organization. Center punch sets are used for marking workpieces before drilling or machining, providing a starting point for drill bits. The knurled grip helps maintain control and reduces the risk of slippage. This set is suitable for general machining, maintenance, and fabrication tasks where accurate layout is required.
