After the workpiece is clamped once on the machining center, the digital control system can control the machine tool to automatically select and replace the tool according to different processes, automatically change the spindle speed of the machine tool, the feed amount and the movement track of the tool relative to the workpiece and other auxiliary functions, which are completed in sequence. Multi-process machining on several sides of the workpiece. And there are a variety of tool change or knife selection functions, so that the production efficiency is greatly improved.
Due to the concentration of the process and automatic tool change, the machining center reduces the time for workpiece clamping, measurement and machine adjustment, so that the cutting time of the machine tool reaches about 80% of the machine start time (only 15 to 20% for ordinary machine tools); It also reduces the workpiece turnover, handling and storage time between processes, shortens the production cycle, and has obvious economic effects. The machining center is suitable for small and medium-sized batch production with complex parts, high precision requirements and frequent product replacement.
USB 2.0 Hub
Another version of USB HUB.When comparing 2.0 and 3.0 there are a few major differences. First the transfer rates: USB 2.0 offers transfer rates of 480 Mbps and USB 3.0 offers transfer rates of 4.8 Gbps - that's 10 times faster. Note that the transfer speeds also depend on the device in use in addition to the bus type and USB ports and cables.
