MOTION CONTROL: The most critical part of any metal-cutting machine is the spindle that drives the cutting tool. With its broad product line, featuring motorized or separately driven spindles, spindle motors and built-in high torque or high-speed applications, Siemens Energy & Automation offers standard or custom solutions to machine tool OEMs and end users. Today’s machine tools are equipped with single or multiple spindles in two basic designs. The first are motorized, direct drive spindles, where the motor is integral with the spindle and the entire assembly, including bearings, motor, drawbar and tool retention, are all in one cartridge. The second are separately driven spindles where the spindle itself is driven by a separate motor. The drive mechanism can be belt, gear box or coupling for direct drive. The spindle houses the drawbar, tool retention system and, sometimes, tool coolant. In the case of directly coupled spindles, the motors can have hollow shafts with the coolant rotary union mounted to the back of the motor. Motorized spindles are becoming the norm in advanced machine tool design, as their compact configuration, high-speed machining performance, superior accuracy and long service life are outstripping the conventional belt driven spindles. Because all functions are built into one compact cartridge or block, these spindles offer the machine designer more flexibility, less space and a higher degree of performance. Using synchronous motor technology, these spindles are more efficient, cover a broader speed, power and torque range and can be used for more precise applications. Weiss spindles can be built to speeds as high as 80,000 rpm
By implementing efficient and thorough quality-management processes, companies can help prevent or mitigate the effects of the supply-chain issues that reportedly plagued the Apple iPhone 6 before its release this week.
Have you ever accidentally abandoned a document on the office printer simply because you didn't feel like getting up to retrieve it right away? Well, fellow American, now your printer can come to you. Meet the Fuji Xerox.
Two small, wheeled robots can "see" through a concrete wall using nothing but WiFi wireless communication. They can detect and measure everything on the other side: people and objects, their positions and geometry, whether they're moving, and what materials they're made of.
