With all the advances in digital printing technologies in recent years, today's large format printers can create visually stunning signs and displays. Yet even the highest-resolution print mechanism is only as good as the actuator that positions it. Gandy Digital recognized the crucial role that actuators play when it designed our ServoNut Power Module into the table axis of a groundbreaking new printer called Pred8tor. This new printing system is a lightening-fast, UV flatbed printer with the ability to handle sheet up to 4x8 ft as well as roll stock. “Our new machine prints high-resolution 900 dpi photographic quality images…

Avoiding Backlash At ATX West

At the ATX West show this week, Mike Everman starred in an Engineering TV segment about backlash in motion systems—and how to avoid it. Mike also gave an overview of Bell-Everman's newest rotary motion stage, the ServoBelt 200. Watch the entire video below.   Click here to configure and request a quote for ServoBelt Rotary.

ServoBelt Rotary Gets Big

New model offers precision positioning for heavier loads ServoBelt Rotary has become one of our most popular products, thanks to its combination of positioning performance, compact form factor and large through hole. Now even more applications will be able to reap these advantages. We recently developed a new ServoBelt Rotary capable of handling far heavier loads than the ServoBelt 100, our next largest model. Increased Heft. Called the SBR 200, the new rotary stage provides: A 200-mm through hole, or twice the size of SBR 100. Continuous torque to 38 N-m, or more than 5 times the maximum torque of…

New ServoBelt Rotary and More At ATX West

The latest addition to our ServoBelt Rotary (SBR) line will debut at the ATX West 2011 Show in Anaheim, Calf., February 8 – 11. The new SBR 50 packs all the advantages of the original SBR100 into a smaller package that makes it a cost-effective alternative to direct-drive motors in precision, light-duty rotary positioning applications. The new SBR features a through hole of 50 mm, half that of the original SBR but still very large for its overall size. Like the larger SBR 100, which will also be on display at the show, the new model offers a geometric accuracy…
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…

A Smaller ServoBelt For Biomedical Machines

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…

ServoBelt Action On Mike Everman’s Blog

ServoBelt continues to get bigger and better. To see its latest capabilities in action, check out these new videos and photos on Mike Everman’s Technical Interest blog. One video shows a ServoBelt dual-carriage stage that stretches to 22 feet long. The same customer also bought a 90-foot ServoBelt gantry, the longest unit to date. Another video shows a ServoBelt actuator in use at NASA’s Johnson Space Center, where the ServoBelt rocks a quarter-scale model of the new Crew Excursion Vehicle. Videos and photos show counterbalance tests of a ServoBelt z-axis and a ServoBelt gantry set up with a 20 nanometer…
