Machine Tool Probing
Machine Tool Probing
Machine tool probing solutions from Hexagon Metrology measure workpieces on milling machines, machining centers, lathes, turning/milling machines, grinding machines, special machines and robots. Both in small businesses and in middle or large-scale production, workpieces are not only aligned, but geometries are inspected while still on the machine.

These machine tool probes facilitate daily work, reduce manufacturing time and costs and increase the possibilities of modern machines. Probe types include Infrared touch probes, radio touch probes and tool setters along with the necessary software and applications support.




m&h Machine Tool Probing


Touch probes from m&h measure workpieces on milling machines, machining centres, lathes, turning/milling machines, grinding machines, special machines and robots. Constant production quality also requires the use of reliable accurate tooling. One vital requirement is precise tool data. m&h touch probes for tool measurement detect tool length and tool radius directly on the machine.

m&h Infrared Probing Systems


m&h infrared probes are touch trigger probes. When approaching a workpiece surface, the stylus deflects and a trigger signal is transmitted to the receiver by infrared light. Interference-free signal transmission between probe and receiver is absolutely vital for process-reliable measuring on machine tools. HDR (High Data Rate) technology avoids interference caused by ambient light from outside and inside the machining area. On the one hand we use the 75 Hz transmission frequency which is different from worldwide line frequencies of 50 Hz or 60 Hz, respectively. On the other hand, an extremely high data rate of 9600 light pulses/sec prevents interference from pulsing machine lamps. Adjustable transmitting power and large transmitting angles go without saying for m&h touch probes. Large receiving angles and microprocessor-controlled evaluation of receiving signals give an absolutely perfect infrared light transmission.

m&h Radio-wave Probing Systems


m&h radio-wave probes are touch trigger probes. When approaching a workpiece surface, the stylus deflects and a trigger signal is transmitted to the receiver by radio wave. This receiver converts the radio waves to an electrical signal sent to the control. Interference-free signal transmission between probe and receiver is absolutely vital for process-reliable measuring on machine tools. Radio transmission is effected in the 433 MHz frequency band being internationally approved and providing particularly high penetration. 64 channels can be easily adjusted on the digital display both on the probe and the receiver. The patented SCS (Self Channel Select) technology of the microprocessor-controlled receiver responds to interference signals by continuously checking the environment. The receiver will block corrupted frequencies from further use and will suggest the best alternative frequency. Combining these two technologies ensures process-reliable radio transmission.

m&h Temperature Probe Systems


By providing a fully automatic measurement of the part temperature at any stage of the machining process (patented), the temperature probe enables manufacturing processes to be controlled and machining parameters to be adjusted during production. Interference-free signal transmission between probe and receiver is absolutely vital for process-reliable measuring on machine tools. When using infrared light transmission, HDR technology (High Data Rate) developed by m&h and adjustable transmitting power guarantee process reliability. When using radio-wave transmission, the use of a high-penetration frequency range as well as the SCS technology (Self Channel Select) developed by m&h ensure interference-free function with a broad transmission range. Thus, a consistently high manufacturing quality and highest process reliability are achieved.

m&h Laser Tool Setters


Non-contact tool measurement allows automatic checks for tool wear or breakage. Constant production quality requires the use of reliable accurate tooling. One vital requirement is precise tool data. The data is automatically transferred to the tool table of the control. Periodic tool checks for broken tools or wear create additional production safety. The Laser Tool Setter from m&h will do this job, saving time and increasing reliability.
