In recent years, it has entered the field of ultra-precision parts processing technology. From the perspective of development, it will play a greater role in the next century. Today's EDM is close to the level of ultra-precision machining in terms of its function and machining quality. Taking WEDM as an example, by using secondary cutting, the cutting accuracy is ±2μm, which can achieve high surface quality. ; From a development point of view, ultra-precision machining technology has been advancing to a higher level, so its definition is also difficult to determine, and the accuracy has continued to improve over time, and metrology is the first to bear the brunt.
The main features of precision parts processing are precision automatic lathes, with five sets of tool rests, which are respectively equipped with micro-card fine-tuning to achieve high precision of the workpiece; more than 10 tools can be installed according to the workpiece processing process. Two-axis device; the main shaft adopts an electromagnetic clutch, which drives the tapping main shaft, and uses the high-speed rotation and the rotation difference of the mechanical main shaft in the same direction to carry out the tapping.
Precision parts processing technology is a comprehensive system engineering. Its development makes comprehensive use of the progress of machine tools, tools, measurement, environmental technology, microelectronics technology, computer technology, numerical control technology, etc. It is an important means for science and technology to develop to a higher level, and it is also a key technology that must be broken through at this stage.
