Digital Indicators Feature Versatility Enhancements
Mahr Federal offers the next generation of its µMaxµm line of digital indicators.

Rugged, Light-Weight Digital Indicators
The µMaxum II line of digital indicators offers a range of new features including dynamic max, min and TIR; two-point difference measurement; multiplier factor for ratio measurements; indicator serial number identification; resolution to 10 micro-inches; selectable continuous output; and long battery life.  

Height Gage Offers Precision, Ease of Use
Built for production operations, the Digimar 816 CL height gage from Mahr Federal is designed to provide accurate measurements without complicated procedures.

Enhanced Digital Caliper Line
The updated line of MarCal digital calipers features lapped guideways, a reference system that retains the zero-position setting and additional product options and accessories.

Cylindricity Machine with Automated Probing System
The MMQ 200 Formtester cylindricity machine features an automated T7W probing system.

Cylindricity Machine With Automated Probing System
 The MMQ 200 Formtester cylindricity machine features the T7W, a ±360 degree, motorized, bi-directional probe designed for automated probe positioning.

Software For Form Measurements
Mahr’s EasyForm 3. 0 is standard on all new MMQ 100 and 200 Formtesters and is available as an upgrade for a variety of older systems.

Cylindricity Measuring Machine
Mahr Federal’s MMQ 200 Formtester cylindricity measuring machine extends the capability of the MMQ Formtester line, and is tailored for measuring cylindricity and other deviations of form and position. Equipped with EasyForm version 3 Software, the machine is compact, fast, easy to learn and operate, and is at home in the metrology lab or on the shop floor, the company says.

Universal Length Measuring Instrument
 The Linear 100 is a high precision, universal length measuring instrument for rapid, high-accuracy internal and external measurements directly on the shop floor. The instrument features a direct measuring range to 2″ (50 mm) and an application range to 4″ (100 mm). Key features include an adjustable 3″ × 3″ (76 × 76 mm) measuring table for precise position adjustment of the part when measuring ODs.

Linear ID/OD Indicator Gage
For use on the shop floor, the Linear 100 is a high-precision, universal-length measuring instrument for rapid, high-accuracy internal and external measurements. With a direct measuring range of 2" (50 mm) and an application range of 4" (100 mm), the simple design makes it possible for the instrument to measure quickly and to adapt to new measurement tasks, the company says. For example, the instrument can be used to measure both lengths and diameters tasks such as measuring the dimension over two balls on gear ODs.

Measuring ID/OD On The Shop Floor
Mahr Federal’s bench-mounted indicator gage is said to provide a handy way to measure ID and OD on the shop floor. Available in both T-plate and V-plate styles and in two sizes, the 36 B ID/OD indicator gage can measure IDs from 0. 75″ to 9″ and ODs from 0.

Universal Gear Tester
Mahr Federal introduces a Class 1 universal gear tester that provides fast, accurate analysis for a range of gear and gear tool applications on gears with ODs as large as 400 mm. The system is part of the GMX series and incorporates a four-axis PowerPC controller with automatic tailstock and high-accuracy 3D scanning probe head. The system provides a solution for both universal and specialized gear manufacturing processes.

Metrology System Features White Light Interferometry

Measuring Taper For Toolholders And Spindle Applications
Companies concerned about strict quality requirements regularly check toolholder tapers for wear or inaccuracy because these conditions can jeopardize the results of a critical operation. However, a shop can check tapers quickly and reliably with air gages. These devices can be used effectively without special operator training. For measuring taper in a production environment, few other methods can match the speed and performance of air, as multiple-circuit air jets can be placed in very small taper gages.

Pump Maker Gains Production Efficiency With Smart Gaging Choices
The challenge facing this pump manufacturer was to make the high-tolerance inspection process so efficient that parts could be checked randomly by several machinists, without causing delays that would slow production.

Surface Finish: A Machinist's Tool. A Design Necessity.
Simple "roughness" measurements remain useful in the increasingly stringent world of surface finish specifications. Here's a look at why surface measurement is important and how to use sophisticated portable gages to perform inspections on the shop floor.

Piston Maker Boosts Quality With Special Geometry Software
A leading manufacturer of pistons for high performance engines has improved its manufacturing accuracy and quality control by using a software package developed especially to measure the unusual geometry of pistons.

Auto OEM Grinds 8,000 Parts Per Hour To +/-2 Microns
A new industrial controller this company is integrating with its high-precision centerless grinders is helping a Big 3 automaker turn out precision parts at 8,000 per hour.

Measuring Part Geometry On The Shop Floor
Measuring workpiece dimensions is relatively simple for machine operators but measuring workpiece geometry which involves more complex comparisons of part shape to an ideal shape--is now also practical on the shop floor. The gaging equipment for doing this is coming down in price while becoming easier to use.
