Form measuring machine doubles accuracy
Form measuring machine more than doubles the accuracy in roundness measurements, improves straightness measurements and offers faster measuring speeds.
The new compact MarForm MMQ44-R Formtester from Mahr Federal offers more than double the accuracy in roundness measurements, improved straightness measurements, and faster measuring speeds In addition, a harmonics analysis software module now evaluates part harmonics up to 1024 upr

Mahr form measuring machine checks spindles
In manufacturing ultra high precision air bearing spindles, Air Bearings chose a Mahr Federal machine to check spindle characteristics such as roundness, concentricity and cylindricity.
Measure form precisely on the shop floor
Form Measuring Machine delivers lab quality 3D and form measurements to the shop floor and its automated measurement and low uncertainty facilitate precision results.
"The roundness error specification on this new MMQ44-R has been reduced to 0.02 micron, making it one of the most accurate in the industry," said Danny Moss, senior product manager, Surface/Form Systems for Mahr Federal.
Straightness error, too, has been reduced to 0.15 micron/100mm, and with our new software package, measuring speeds are as much as 40% faster than earlier versions." Equipped with an optional CNC 360 degree motorized probe for fast, versatile, and reliable measurements, and the latest version of Mahr Federal's Form-PC software, the MMQ44-R is capable of measuring a wide range of features well beyond the scope of most roundness measurement systems.
The T7W CNC motorized probe can automatically position itself over a full 360 degrees of rotation in less than one-degree increments.

Surface finish gauge measures multiple parts
Mahr Federal's surface finish guage will index and measure multiple small parts, such as gears, fuel injector components, or inner and outer bearing components.
Mahr releases optical surface measurement system
Mahr Federal said that its MarSurf WS 1 surface measurement device uses white-light interferometry to provide fast, high precision, non-contact measurement of surface texture.
Height gauge has three ways of measuring
Height gauge offers three measurement techniques: a normal keypad initiation; a Quick Mode feature and two Speed Keys to move the measuring carriage to the desired position.
This software-driven probe eliminates the need for operator involvement during measurement processes that require probe repositioning.
The T7W probe head is the same used on the Mahr Federal Reference Formtester, the MFU 100.
The MMQ44-R Formtester measures roundness, cylindricity, straightness, flatness, concentricity, coaxiality, radial run-out, total radial run-out, axial run-out, total axial run-out, parallelism, perpendicularity and angularity, while adhering to both National and International standards.
Whether performing circular or straight-line measurements, interruptions like grooves and cross holes are detected automatically, regardless of their positions, and the corresponding profile interruptions are not evaluated.
Circular measurements can be taken in sections as small as 15 degrees.
The system will measure parts up to 620mm (24.4in) in diameter and 640mm (25.2in) in height.
Despite its compact size, this Mahr Federal Formtester easily handles large and heavy parts, up to 134 lb.
A variety of options allows users to easily adapt the MMQ44-R to special requirements.
An extensive assortment of probe arms, styli and other accessories is available, and for extremely precise workpieces, linear scales on the X and Z axes provide high precision positioning accuracy.
The measuring X-axis can be designated as a horizontal measuring axis, allowing horizontal straightness and multi-radial flatness measurements.
The Windows-based FORM-PC software has been consistently upgraded and field proven.
Quick and Easy icons are used to lead the user through individual measurements and Teach-In-Programming creates fast and efficient measurement programs even for complex parts and part families.
This powerful software analyses the data, displays results as the part is being measured, and generates a printout before the next part can be loaded.
Three additional software modules extend the performance of the MMQ44-R system.
First is a Data Transport Tool module that allows measurement data to be exported as ASCII, Microsoft Excel files, or in qs-STAT format.
A Fouier Analysis (Harmonics) module allows the evaluation of harmonics up to the 1024th harmonic, and a Piston module evaluates ovality, tolerance monitoring of both circular and linear (skirt) profiles, and pin bore axis location relative to the main oval axis.
The MMQ44-R Formtester is designed to be equally at home on the factory floor or in the lab.
No air supply is required and its high-precision mechanical bearing ensures stability, exceptional accuracy and repeatability.
A reliable collision protection system immediately stops the machine if it encounters even a minor counter force, to protect people, workpieces and the equipment.
The MMQ44-R Formtester is designed for easy installation, minimal maintenance and low operating costs.
