Mahr now offers an innovative automated solution for measuring surface roughness on workpieces directly within the CNC machine tool. To achieve this, the MarSurf MC 510 measuring device is fully integrated into the tool holder, where it performs measurements using a vibration-resistant, tactile skidless system – in compliance with standards and with high precision down to Rz 1 μm.

Advantages

• Automated process for fast measurement of surface parameters

• Precisely reproducible measurements without operator influence

• Insights into tool wear, leading to reduced tool costs

• Protected against contamination thanks to robust construction

• Flexible machining processes through direct control and measurement data output in NC code

• Wireless communication with Edge PC

• OPC UA Interface and closed-loop-ready

• Fully automatic and reliable documentation of surface parameters without expert knowledge

The MarSurf SD 140 BG can measure both roughness and contour features – all in a single measurement run. The measuring station offers ease of use combined with reliable quality assurance thanks to its high functionality. This makes it an ideal entry-level model for stationary surface metrology.

Advantages

• Measure roughness and contour in a single run

• Tool-free probe arm quick-change function

• Electronic probe arm detection

• Automatic probe force selection

• Defined starting position with aligned axis

• Flexible clamping system: mounting plate (390 mm x 450 mm) with 50 mm hole pattern

The Micromar 844 EWR(i) digital 3-point inside measuring device for measuring inside diameters features an ergonomic handle with a retractable lever for fast, self-centering measurements across the entire measuring range, as well as a rotatable display with touch controls.

Advantages

• Inside measuring device with lever retractionfor fast and self-centering measurement of various diameters

• Integrated measuring system with convenient rotatable display module

• Wide range of sizes for measuring ranges from 6 to 100 mm

• Measurement preset: 3 PRESET and tolerance values possible

• Connectivity: Model available as 44 EWR with bidirectionaldata output (cable) or 44 EWRi with integrated wireless (radio transmission)

• Remote operation via the free MarCom Professional software available for download

• Available as a single unit or as a set

 Portable 3D surface measuring device for use in production environments. Enables precise measurement and analysis of surfaces – non-contact, material-independent, and fast.

• Versatile: Roughness and microgeometry measurements in a single system

The OptoShaft TT tabletop measuring system is a universal, compact measuring device that can be used as a PLC-controlled measuring station for a wide range of measurement tasks in R&D, quality assurance, and manufacturing.

Advantages

• High-precision rotary table and motorized Z-axis
  
  
• Enables the measurement of full-surface bearing seats on gear shafts as well as the measurement of flanks on worms and spindles
  
  
• The sensor can be positioned vertically and, with an attachment lens, can also measure inside bores.
  
  
• Parts with complex geometries, such as worms, lead screws, and drill bits, can also be measured.
