Reaching New Levels of Speed, Lifetime, and Force Sensitivity

Woburn, MA –Motion Control Components Ball Screws – Case Study –

Situation:

In the area of automated laboratory equipment, servo-controlled pipetting modules are a key component of high-throughput systems. A major, global OEM had been using an off-the-shelf linear actuator to drive the pipette. This actuator had a limited range of capability in terms of speed, positioning accuracy, and force sensitivity. Although it met the minimum technical requirements and was cost-effective, engineers soon were asked to push performance to the next level.

 

Challenge:

The company decided to develop a next-generation system. Throughput was essential, as it wanted to target the largest hospitals and laboratories handling tens of thousands of samples annually. The pipetting module also needed to have enhanced flexibility to support a greater variety of operations. It should allow for a wider range of speeds and be highly accurate in both positioning and bottom-finding. Engineers were also tasked with achieving a 10-year lifetime with little or no maintenance. This high lifetime was critical because their business model included free field service. To meet these new requirements, the actuator would have to be redesigned. In particular, the bearing configuration did not support the required accuracy and sensitivity. The supplier was unwilling to modify its design. Company engineers realized that they would have to design a custom actuator.

Resolution:

They came to Steinmeyer for a precision ground ball screw. They knew that Steinmeyer had world-class quality and a very wide selection of miniature screw sizes. For this project, they were able to consider shaft diameters of 5mm or 6mm, with pitch down to 0.5mm! They selected a 6mm screw to meet the challenge. Company engineers conducted extensive performance testing on the first prototype quantities. They put the new module through an exhaustive regimen of motion, and measured positioning, force sensitivity, friction torque, motor current, and other parameters. They verified that their module design met all of the new performance requirements. The company has since achieved FDA approval for the new system and formally launched commercial sales.

Future Plans:

Noise minimization is important for laboratory equipment. The next generation pipetting module will look to ensure the quietest possible operation. The OEM will be evaluating our proprietary super-finishing process called optiSLITE. This technology removes the largest irregularities left over from thread grinding of the shaft. The resulting surface yields a noticeably smoother and quieter operation.

Steinmeyer Announces the optiSLITE Line of Miniature Ball Screws: Our Smoothest Raceways Ever Deliver Optimum Accuracy!

Motion Control Components - Steinmeyer optiSLITE Ball Screws

Steinmeyer Logo

 

BURLINGTON, MA –Motion Control Components – Steinmeyer, a global manufacturer of precision ground ball screws, introduces a new miniature ball screw line called optiSLITE. These screws feature low friction torque that delivers smoother running and enables greater accuracy. The result is superior positioning performance in semiconductor, optics, medical instrument, and metrology applications

optiSLITE miniature ball screws are expertly manufactured in Germany like all Steinmeyer products. The ball screws undergo a proprietary finishing process that removes micron-sized defects on the shaft raceway. The elimination of these irregularities enables optiSLITE miniature ball screws to provide the highly-accurate positioning required in precision applications.

All of our miniature ball screws are meticulously engineered and manufactured to provide highly-accurate positioning,” stated Bruce Gretz, Executive Vice President of Steinmeyer, Inc. “with our smoothest raceways yet, optiSLITE miniature ball screws deliver lower friction torque and smoother operation than ever before.
