MMQ400-2 is a universal shape measuring machine that can be used in inspection rooms and production sites


features

MMQ 400-2 can perform various application evaluations on ultra long workpieces according to DIN ISO 1101 standard, with high-precision measurement axis design, Z-axis and X-axis, and can achieve measurement of various geometric tolerances.
MarForm MMQ 400-2 is suitable for
• High precision workpieces

• Common ultra long workpieces
• Large and overweight workpieces
• Production site or testing room
MarForm MMQ 400-2 has 5 design versions to meet your needs, allowing for optimal design for each measurement task:
Equipped with automatic or manual centering and leveling work turntable
Equipped with 500mm or 900mm vertical Z-axis, 280mm horizontal X-axis, or:
Equipped with a 350mm vertical Z-axis and a 180mm horizontal X-axis
Equipped with digital linear control system for X-axis and Z-axis to meet the requirements of optimal measurement repeatability
MarForm MMQ 400-2 can be a semi-automatic measurement center
When equipped with a manual centering and leveling work turntable, but when equipped with an automatic centering and leveling work turntable and T7W automatic measuring head, it can also be a fully automatic measurement center, perfectly suitable for your high-precision workpiece testing tasks without any manual intervention.
Fully automatic shape measuring head T7W
The T7W measuring head is equipped with a motor-driven rotating shaft, which allows the measuring arm to asymptotically enter the corresponding contact position, making measurement on the cylindrical surface and end face possible. As a zero positioning probe, the T7W probe can achieve automatic conversion between external and internal measurements, as well as conversion between top-down and bottom-up measurement of end faces, without the need for operator intervention.
Due to the design of the motor-driven shaft, the measuring arms of the T7W probe can be automatically replaced, which is called a star shaped probe. Each measuring arm has different set contact points, allowing for automatic replacement of probes with different geometric shapes during measurement.
Optional: roughness measurement
It can achieve a combination of geometric tolerance detection and roughness parameter measurement functions. By using MarForm MMQ 400-2 to detect the form and position tolerances of workpieces, certain typical roughness parameters such as Ra and Rz can be obtained without the need to transfer the workpiece to another measuring device for re clamping.
Program control and motor drive enable the device to automatically switch back and forth between shape gauges with ruby measuring balls and PHT 6-350 roughness gauges. This avoids the impact of operator intervention on accuracy, and various probes can achieve automatic positioning from both vertical and horizontal directions. The motor driven shaft design of T7W enables the probe to achieve any 1 ° incremental rotation positioning.
