Helmel Engineering has introduced a powerful new solution in the realm of coordinate measuring machines (CMMs) with its Microstar Model 320-185, a system engineered for high-speed, autonomous, and ultra-precise measurement operations. At its core, this advanced CMM integrates the cutting-edge Renishaw PH20 probe system—enabling true five-axis measurement capabilities that bring speed, versatility, and increased throughput to inspection processes.
The PH20 probe, paired with the UCCT5 controller, delivers infinite positioning across a 230° to 360° head range. This dynamic range works in harmony with the CMM’s X, Y, and Z-axis motions to unlock enhanced measurement access and efficiency. Notably, the PH20’s “head-tap” mode allows for rapid autonomous data collection without moving the CMM structure, minimizing vibrations and cycle times while improving repeatability.
The Microstar 320-185 has been thoughtfully designed with mechanical upgrades to ensure stability and long-term accuracy. A reinforced Z-axis structure improves stiffness, while a larger bearing separation reduces deflection. The X-axis carriage leverages a dual-bearing flexure stabilizer system along with self-aligning linear bearing mounts, ensuring smooth and precise motion even under aggressive scanning speeds.
To support high-resolution measurements, Vionic stainless steel tape scales with 50-nanometer resolution heads have been integrated. These are mounted on steel surfaces to maintain thermal consistency, and the system includes controller-based error correction and temperature compensation, critical for environments with fluctuating conditions.
The drive system has also received a major performance boost. Equipped with steel- and Kevlar-reinforced belts and stronger tachmotors on all axes, the Microstar 320-185 supports more aggressive motion parameters—enabling faster, more efficient part inspections without compromising accuracy. The system is also built for durability, with additional protections available for harsh shop floor environments.
Initially offered with a measurement envelope of 20″ × 30″ × 18″, the Microstar 320-185 includes the robust CMM Manager CAD software and a TCR20 six-port automatic stylus changer, ensuring flexibility across complex inspection routines and part geometries.
With these enhancements, Helmel’s Microstar Model 320-185 offers a complete, high-performance metrology solution that delivers speed, precision, and automation—making it ideal for manufacturers demanding tighter tolerances, faster feedback loops, and increased measurement reliability in today’s high-mix, high-speed production environments.
