Bolts and screws can be outfitted with a variety of different head styles. Which style an engineer specifies depends on several factors: the type of driving or installation equipment used, the type of joint load, and the external appearance desired.
Some plastic resins get blended with fillers to reduce costs. Properly used mineral fillers can also improve moldability and stability, increase heat-deflection temperature, reduce thermal expansion, and change other performance characteristics as well.
Engineers have long used stress-strain curves to uncover a host of material properties including elastic limit, elastic and plastic ranges, yield point, ultimate and rupture strengths, and the moduli of resilience and toughness.
Ball-screw drives have long been considered noisy by definition. Companies that buy and use them are increasingly requiring that their machine tools operate more quietly to improve the work environment by reducing noise levels.
Today’s conveyor systems have to deal with a wide variety of products and smaller batches, yet still be easy to reconfigure for handling new tasks. To address those demands, Bosch Rexroth Corp. developed the VarioFlow plus chain-conveyor system.
