Mahr Inc. announced a new family of Micromar 40EWRi-L digital micrometers with high speed measuring spindle positioning. The digital micrometers, with the latest MarConnect interface, allow measurements that are 10 times faster than a standard micrometer, saving the operator time when numerous different dimensions need to be measured on a single workpiece. The “non-rotating” sliding spindle also protects sensitive workpiece surfaces against measuring damage.
The integrated wireless system makes the measurement very convenient and significantly accelerates the measurement of workpieces while at the same time protecting the surface of the test specimens. The spindle makes a 5 mm movement with one revolution of the friction drive sleeve and can be positioned 10 times faster than a standard micrometer. This saves the user significant time, especially when measuring workpieces with different sizes. By carefully contacting the part with the non-rotating sliding spindle, scratches (e.g. from grinding dust residues on sensitive and finely machined part surfaces) are avoided. In addition, the non-rotating system provides the ideal solution for measuring film thickness without twisting and damaging these delicate, thin materials during measurement. The large display and intuitive operating concept support users in production and quality assurance, featuring measuring reliability, fatigue-free reading and simple operation.
