“Design and manufacture a wireless transceiver that performs mixed transmission of digital-analog signals on the same channel. Among them, the digital signal is composed of a set of 4 numbers from 0 to 9; the analog signal is a voice signal with a frequency range of 100 Hz to 5 kHz. Using wireless transmission, the carrier frequency range is 20~30MHz, the channel bandwidth is not more than 2...
After the workpieces processed by Dongguan CNC are clamped once on the machining center, the digital control system can control the machine tool to automatically select and change tools according to different processes, automatically change the spindle speed, feed, and the motion path of the tool relative to the workpiece, and other assistance Function, complete the multi-process processing on several surfaces of the workpiece in sequence. And there are a variety of tool change or tool selection functions, so that the production efficiency is greatly improved.
Due to the concentration of processes and automatic tool change, the machining center reduces the time of workpiece clamping, measurement and machine tool adjustment, so that the cutting time of the machine tool reaches about 80% of the machine start time (normal machine tool is only 15-20%); at the same time; It also reduces the work piece 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 batch production with complicated parts, high precision requirements, and frequent product replacement.
1. The Dongguan CNC processing center has good processing consistency and economic benefits. Compared with other CNC machine tools, it has the following characteristics:
2. The workpieces processed by Dongguan CNC are complex and the process flow is very long, which can eliminate the human interference factors in the process flow, and has high production efficiency and quality stability.
3. Due to the concentration of processes and the automatic tool changer, the workpiece can be milled, drilled, bored, expanded, reamed, tapped and other compound processing with precision requirements after one clamping.
4. When there is an automatic exchange table, one workpiece can be clamped on the other when the workpiece is being processed, thereby greatly shortening the auxiliary time and improving the processing efficiency.
