The German Mal roundness and cylindricity meter can provide various accessories to help you measure workpieces. We also provide various options and attachments to help you simplify
Easily measure special workpieces.
·Valuing product accuracy can benefit you from it
Everyone has doubts about the accuracy or uncertainty of measuring equipment - Mahr believes that the verification of technical data of measuring equipment cannot be based solely on those that meet standards. Because these technical data can usually only be achieved under perfect environments and measurement standards for workpieces.
However, as a leader in the roundness instrument market for decades, the German Mahr Mal MMQ 400 roundness instrument cylinder has proven that it can be completely reassuring in terms of accuracy.
This depends on the countless measurements and valuable feedback provided by customers around the world, which Mahr needs to face when researching and expanding equipment performance. Therefore, now we will also mention more about the accuracy of measurement equipment in practical applications, as these data are currently achievable by customers in the actual measurement process.
We cannot agree with the idea that the appearance of theoretical data in many measuring devices indicates that it can be applied in most measurement processes. Our goal is to increase more accuracy and reduce the sensitivity of instruments affected by external factors.
The main factors affecting the sensitivity of measuring instruments are changes in the operator and environment. The impact of human error includes: judgment of force measurement, adjustment of measuring needle angle, positioning, clamping of workpieces, positioning of measuring points, measurement methods, and understanding of measurement parameters. An excellent measurement system should be able to avoid the influence of human factors and also make necessary self corrections to these data. Simple use, support for different applications, and automatic protection programs are also essential for an excellent software.
The environmental impacts include temperature control, vibration, and cleaning of workpieces (coolant, surface dirt)

To improve practical accuracy and expand application range, the German Mal MMQ 400 roundness and cylindricity instrument has set this goal and is at the forefront of the development of the times
The efforts and attempts of developers during the development process
The once highly successful fully automatic T7W sensor has been perfectly replicated on the MMQ 400 roundness and cylindricity meter, and the unique features of the MFU100/8000 roundness and cylindricity meter have also become part of the new design of the MMQ 400 roundness and cylindricity meter.
The fully automatic CNC controlled T7W sensor reduces the impact of human error through automatic control in the measurement direction, automatic rotation of the measuring needle, and convenient replacement of magnetic measuring needles. The extreme small force measurement and outstanding linearity improve the accuracy of the measurement.
MarWin Professional Form software has also achieved success in tens of thousands of usage fields, and of course, the MMQ 400 roundness meter should not be an exception. The convenient human-machine dialogue interface enables you to quickly and conveniently create programs, and we have also gained a lot of experience in the software platform FORM-PC, which has been integrated into the new AdvancedForm software. Some new features include: automatic contact of the instrument to improve measurement uncertainty and repeatability of instrument accuracy, ensuring that operators can independently complete operations and simple and easy to understand operation methods.
·Quality assurance is based on capability research

Absolute stability and superb precision

The design of the entire Mal MMQ 400 roundness and cylindricity tester has durability, stability, and resistance to external influences. The basic data of the instrument represents a new benchmark for similar shape measuring instruments.

base
The base serves as the foundation for each measuring instrument, and the highly stable steel body internal reinforcement structure ensures the high mechanical stability of the Mal MMQ 400 roundness cylindricity meter, and uses an embedded mechanical rotating shaft.

Vertical measurement axis

The vertical measurement axis is generated entirely from the bottom of the base. It is enclosed within a solid steel base, specifically designed to precisely coordinate with the rotating shaft of special control components. This key cooperation ensures its long-term stability to ensure that it is not affected by the environment. Like all mechanical components, this rotating axis uses CAD optimization elements.

heatisolation

Temperature changes are the main opponent of precision measurement. However, the conditions in the measurement room cannot always be perfect. When the environmental conditions are not ideal, the Mal MMQ 400 roundness cylindricity meter was born for this reason. The use of homogeneous materials ensures that the geometric shape of the Mal MMQ 400 roundness cylindricity meter remains accurate, thus maintaining uniform thermal expansion even during temperature fluctuations. Both the base and vertical axis are heat sealed, and brief changes in ambient temperature have only a slight impact on the measurement results. Internal heat sources (motors and electronic components) are also insulated to prevent their thermal radiation from affecting the measurement axis.

Mahr Mal's mechanical ball bearings from Germany have increased environmental insensitivity by 70 times compared to air bearings, but maintain consistent accuracy.

Mahr is a leading manufacturer of ultra precision bearings for rotary and linear motion, and supplies them to users around the world. Our clients are distributed in the fields of mechanical engineering, precision engineering, optics, medical technology, and electronic parts production. Mahr produces over 100000 sets of ball bearings annually, Mahr has been producing high-precision air bearings for over 60 years, and through its unique technology, Mahr has been able to combine the advantages of air bearings with the stability of mechanical bearings.
Air bearings, whose interacting components are distributed in an area with a very large air gap. The high degree of fusion results in better radial bounce performance, but only when external influences remain within a certain range. External influences, such as increased external forces caused by driving, irregular load distribution, or environmental vibrations, introduce external forces into the bearing. The impact on accuracy depends on the rigidity of the bearing, which is very low due to the nature of air bearings themselves. Mechanical bearings establish a direct mechanical connection between the rotor and stator through steel balls. This increases the stiffness by 70 times and ensures that external influences are minimal. But the limited number of contact points reduces the degree of fusion, so the accuracy is slightly lower
Low.
However, Mahr, with decades of rich experience, has combined special production processes and materials to create mechanical ball bearings with precision comparable to high-quality air bearings without the weaknesses of traditional mechanical bearings. Even under harsh working conditions, it still maintains its good reliability and accuracy!

Size and flexibility

The Mal MMQ 400 roundness instrument has a large measurement range, which is not only beneficial for measuring large precision workpieces, but also provides comprehensive measurement capability storage and flexibility. The measuring table has a load-bearing capacity of 60 kilograms, and the large-sized rotating table allows you to use various clamps and fixtures (including those with eccentric loading). Due to the column being located at the far right end, there are no problems loading workpieces. A longer measurement axis can support measurements at multiple positions, including the center beyond the C-axis, to determine true parallelism. A larger measuring body also means that larger scale high-precision measurements and stronger resistance to external influences can be achieved. This is a significant advantage of MMQ 400.
After all, who knows what other components you will need to measure in the future?

Compact design

Although MMQ 400 has extremely spacious measurement space, it is already much smaller in size compared to other similar measuring devices. The highly integrated electronic unit and the elimination of the need for compressed air mean that the MMQ 400 only requires one power source (115 volts or 230 volts). Therefore, this ample available space ensures a work environment that is as ergonomic as possible.

Ergonomic working range

Usually, the Mal MMQ 400 roundness and cylindricity tester is operated on a 1150 * 750mm workbench with sufficient space for a display, keyboard, and accessories. The table size allows the operator to stretch their legs and feet freely when sitting down, and a small storage cabinet with pulleys can be conveniently placed or directly placed under the workbench. If you need to draw or prepare measurement plans and programs on the workbench, you can also choose a small workbench with a dedicated display and keyboard as an alternative. In narrow spaces, an 850 * 550mm equipment support platform designed specifically for production sites can also be provided.
The machine can also be easily operated while standing, and the ergonomic manual control panel and sensitive joystick form a very user-friendly overall unit.

The combination of speed and efficiency

Fast speed is not a problem, but combining speed and accuracy to control the movement of the axis is not easy. Currently, saving time in measuring workpieces is important. The Z-axis movement speed of the Mal MMQ 400 cylindricity meter can reach up to 100mm/s, which is three times faster than other similar measuring devices. Adjustable speed and acceleration, as well as faster workpiece alignment speed, thanks to advanced algorithms, combined with three-axis linkage to save valuable time, greatly reduce
Reduced the cost of each measurement.

Reliable security guarantee
When the instrument is running rapidly, it also has the ability to quickly and urgently brake. The design objective of the new MMQ400 is to achieve simultaneous protection of operator and equipment safety, with a series of safety measures to ensure fault free operation, including passive safety measures to prevent possible collision points, over range protection of the probe, thermal overload protection, and collision protection switches, emergency braking through emergency stop switches, and defining collision zones. If the measuring instrument also has a collision test similar to the European NCAP, then the MMQ 400 has already been awarded five stars.
