Our motion systems are often scaled up for large-format manufacturing applications, but we’ve recently taken our technology in the opposite direction to address miniature manufacturing. Case in point: We’re putting the finishing touches on a new 3-axis motion stage for a vision-guided CNC micromachining system. With a work envelope measuring 690 x 450 x 150 mm, this micromachining stage has a large addressable area that might not seem “micro” at all. Yet with a positioning resolution of just 0.5 µm, the stage enables the machining of sub-micron features on larger workpieces. The system is built around around a trio of…

Avid Corporation makes good use of ServoBelt Rotary’s large through-hole and easy installation in a unique vision inspection system for the packaging industry. In bottle manufacturing operations, inspection is about more than just quality control. It’s also a matter of productivity since technicians can spend hours collecting bottle weight and dimensional data to ensure that molding machines and tooling are running properly. Avid Corporation has been making that quality data a lot easier to collect for more than two decades. The company builds a variety of automated and semi-automated vision inspection systems that increase the throughput and accuracy of quality…

ServoBelt is shrinking. And for the makers of biomedical machines and lab automation equipment, smaller really is better. While our full-sized ServoBelt linear axis has been put to work in larger biomedical machines, a customer who makes diagnostic equipment recently asked us to create a compact ServoBelt sized for “benchtop” machines. The result is a new ServoBelt built around 30-mm Bosch Rexroth aluminum t-slot framing and 15-mm profiled bearings–down from the 45-mm framing and 20-mm bearings used on our larger ServoBelts. The new “ServoBelt 30″ is sized for NEMA 23 and smaller motors, versus NEMA 23 and 34 motors for…

The DDT100 Series, our most compact rotary stage, now features new encoder options that can reduce its price by as much as one third. The optional encoders, which can be found on stages with the new DDT100LC designation, are optical code wheels offering either 20,000 or 40,000 counts/rev, or 0.3 and 0.15 mrad respectively. Those resolutions are not as fine as our standard DDT100R models, which still ship with high-end Renishaw optical ring encoders capable of resolutions down to 2 μrad. While some applications do need every bit of the resolution available on the DDT100R, the DDT100LC’s code wheels offer…
