Never-Before-Possible Roughness Measurement

MarSurf GD roughness measuring stations from Mahr Inc. (Providence, RI) provide unprecedented levels of speed, flexibility and intelligent ease of use, allowing users to improve the manufacturing quality of workpieces with faster throughput and higher accuracy for the broadest range of applications. These surface measurement instruments enable profile and waviness evaluations to be carried out in addition to surface roughness evaluations. The MarSurf GD series significantly increases the speed of all moving axes to reduce the cycle time of the measurement process, allowing more throughput which is particularly valuable when used directly in the production environment. The drive units of the machine move the probe with positioning speeds of up to 200 mm/s, making the systems up to 40X faster than predecessors. All Z-axis columns on the measuring stands are fully CNC-capable, with fast positioning speeds of 50 mm/s, which is up to 5X faster than standard Z-axes on the market today.

The MarSurf GD series also offers the ultimate flexibility with available sizes of 140 mm and an industry-first 280 mm. The 280 mm measuring station allows for the measurement of applications that were previously impossible, including larger parts or a series of smaller parts staged together – all on the same machine. Furthermore, all of these machines are equipped with intelligent MarWin Easy Roughness software to provide the ultimate ease of use. Many operations can be performed right out of the box, such as creating instructional UIs to guide a user through all the steps of a specific measurement. The GD Series features a large mounting plate with 50 mm bore pattern, 60 mm Y adjustment, and Z-axis of 350 mm or 600 mm. Available with standard probe arm lengths up to 135 mm (3X length) for measuring ranges up 1.5 mm vertically, these instruments also are capable of measuring contour features such as radius, angle or depth within that range.

All probe arms feature a quick-change magnetic mount to ensure the fastest changeover time, as well as extra security allowing the probe to “break away” in the event of an accidental collision – protecting both the probe and the system. The GD series also includes an integrated turret to rotate the probe to 90 deg for transverse measurement and the ability to rotate the probe system 180 deg to allow “upside down” measurement.
