As cutting speeds increase, so do component lifetime requirements. This two-stage wiper cleans and lubricates to extend ball screw life.
Problem: Precision-ground ball screws designed for 300 to 400 million revolutions once ensured long life. Today, high-speed cutting machines can reach those numbers within a year, and need added protection from adhesive and abrasive wear.
Solution: Segmented plastic wipers, in combination with a continuous felt ring. During operation, pre-loaded finger-type seals clean the shaft, guiding abrasive contaminants away via beveled edges. A liquid lubricant, oil, or grease - stored and distributed by the felt ring - protects against the adhesive effects of micro-welding.
Are they robots or androids? We're not exactly sure. Each talking, gesturing Geminoid looks exactly like a real individual, starting with their creator, professor Hiroshi Ishiguro of Osaka University in Japan.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
