Issues to pay attention to in mirror spark machine forming processing

1. Issues with improving processing accuracy: This mainly includes dimensional accuracy and contouring accuracy. There are many factors that affect contouring accuracy, the first being electrode wear. Therefore, for sharp corners, thin sheets, and the main cavity, it is necessary to decompose the processing. This part of the cavity, like a pattern mold, requires a significant increase in pulse width. Using large pulse width and small current processing primarily addresses the requirement for low wear. Secondly, it is important to prevent re-adhesion, especially with graphite. During high-energy processing, careful observation is needed to prevent damage to the geometric shape of the cavity. Additionally, attention should be paid to selecting an appropriate linear (oscillating) trajectory.

Current Status and Outlook of Intelligent Machine Tool Development

Intelligent machine tools are the foundation of intelligent manufacturing. The intelligence of machine tools can be divided into three aspects: ① The intelligence of machine tool components themselves, including spindle units, feed drives, and structural parts, for purposes such as thermal deformation compensation; ② The intelligence of the CNC system, evolving from the controller of processing equipment to the terminal of the factory network, allowing production data to be automatically collected, enabling real-time communication between machine tools and between machine tools and various management systems, making production transparent and integrating into the organization and management of the enterprise, thus creating intelligent factories; ③ The intelligence and networking of machine tools create conditions for the social sharing of manufacturing resources and the establishment of remote, virtual cloud factories, thereby moving towards a new era of shared economy and creating more value.

Do you know the advantages of a mirror spark machine?

Mirror spark machining is mainly used for the processing of complex mold cavities, especially for complex curved surfaces that are difficult to polish. It can eliminate manual polishing processes, improve the performance of parts, and is of great practical significance in shortening the mold manufacturing cycle. Therefore, it plays a very important role in the mold manufacturing industry. Let's take a look at the advantages of mirror spark machines.

EDM principle

During EDM, one pole of the pulse power supply is connected to the tool electrode and the other pole to the workpiece electrode, both poles are immersed in a liquid medium with a certain degree of insulation (commonly paraffin or mineral oil or deionised water). The tool electrode is controlled by an automatic feed adjustment device to ensure that the tool and workpiece maintain a small discharge gap (0.01-0.05mm) during normal processing.
