MPN #: P7
Tired of inconsistent grind quality and costly re-work? The Marposs P7 Multifunction Electronic Unit for Grinder Process Control gives you real-time measurement and automatic compensation so every part meets tolerance the first time. It connects to your grinding machine and watches the wheel, workpiece and acoustic signals, removing the guesswork that slows production.
Grinding machines often produce parts that drift out of spec because the wheel wears, the workpiece moves, or hidden collisions occur. When this happens, you lose material, face scrap, and your delivery schedule slips. The P7 unit solves these issues by delivering continuous in-process measurement, automatic wheel balancing, and acoustic monitoring that detects contact or faults instantly. With a built-in 5.5-inch color display and Ethernet, RS-232 or fieldbus links, the system talks directly to your PLC or CNC, sending compensation signals that keep dimensions within microns. The result is higher yield, less downtime, and confidence that every batch meets customer expectations.

We are retiring PICOPC Products MNHO-073, MNHO-048 and MNHO-043 and they have reached EOL (End Of Life) as we are introducing new products with better technology. We would recommend you to look into MNHO-095. For Untangle, pfSense, OPNsense, Windows 11, Proxmox VE etc. we recommend MNHO-095 whereas for Sophos, Kerio Control and Endian, we would recommend MNHO-069. (A complete list of supported OS can be found in each product's listing)
