The P4K from MMT is a non-contact optical profile metrology system designed for high-speed, high-accuracy diameter measurement of long cylindrical components. It is the industry standard for medical guidewire inspection, also serving bone drills, arthroscopic shavers, and titanium fasteners in production QC environments. One-click operation and fully automatic scanning eliminate operator influence on measurement results.

How accurate is the P4K optical measurement system?

The P4K achieves diameter accuracy of ±0.5 μm (0.00002 in.) with repeatability of ±0.06 μm (0.000002 in.). An ultra-smooth linear motor with 0.1 μm (0.000004 in.) resolution pulls parts through a laser optical micrometer at up to 3 in./sec (75 mm/sec), acquiring over 10,000 diameter and length readings per second. The system delivers one reading every 30 millionths of an inch (0.76 μm) of part travel. A precision-lapped granite base provides thermal stability and vibration damping to maintain calibration without drift over time.

What parts and materials can the P4K measure?

The standard system handles parts up to 1 m (40 in.) in length, with 1.4 m and 2 m options available for longer components. It measures medical guidewires, arthroscopic shavers, bone drills, titanium fasteners, and other long or multiple short cylindrical parts. Go/No-Go results with clear pass/fail display make it suitable for shop-floor operation. Point-to-point dimensioning with unlimited zoom, English and metric unit support, and configurable warning tolerances alert operators before parts drift out of specification.

How does closed-loop grinder feedback work?

The P4K provides automatic size compensation feedback to Glebar CAM.2, GT-9AC, and GT-610 CNC grinders, enabling closed-loop correction without operator intervention. Built-in SPC reporting, lot control, and data export to Excel and Minitab support statistical process control workflows. An SQL version centralizes measurement data and templates across multiple facilities via intranet for enterprise-wide quality management.
