The materials usually processed by Dongguan automatic lathe are free cutting steel and copper. The free cutting steel has high sulfur s and phosphorus P. sulfur and manganese exist in the form of manganese sulfide in the steel, and manganese sulfide plays a lubricating role in the steel, making the steel easier to cut, so as to improve the production progress of the lathe.......

If possible, start with the detailed machining principle of CNC turning parts machining. The following can be learned:1. The machining principle of CNC machining machine tool, the tools needed for various machining, and the tool path methods used for various workpiece machining.2. Feed rate, rotating speed and cutting rate of various workpieces. How to deal with various unexpected emergencies.......

Determine the process requirements of typical parts and the batch of processed workpieces. The function of the proposed NC lathe is to make preliminary preparations. The prerequisite for the rational selection of NC lathe meets the process requirements of typical parts.The process requirements of typical parts are mainly the structural size, machining range and accuracy requirements of parts. ......

The preliminary steps of Dongguan CNC lathe processing are to determine the process requirements of parts and the batch of processed workpieces, formulate the functions that the CNC lathe should have, make preliminary preparations, and reasonably select the preconditions of the CNC lathe to meet the process requirements of typical parts. The process requirements of typical parts are mainly the structural size, processing range and accuracy requirements of parts.......

Compound machining is one of the most popular machining processes in the field of machining. It is an advanced manufacturing technology. Compound machining is to realize several different machining processes on one machine tool. Compound machining is the most widely used and difficult, which is turn milling compound machining. Turn milling compound machining center is equivalent to the compound of a CNC lathe and a machining center.......

The repair staff shall check all kinds of abnormal phenomena such as light, sound and taste when the obstacles are generated, carefully check all parts of the system, and narrow the scope of the obstacles to a module or a printed circuit board. It is decided to visually inspect the barrier circuit board and carefully check whether there are signs of fuse fusing, component burning and cracking, so as to identify whether there is overcurrent, overvoltage or short circuit. Touch whether the components are loose by hand to check some false soldering and fracture titles.......
