The cause of the failure of the piercing machine in the thread cutting machine

EDM machine punching machine is generally used as an auxiliary equipment for EDM machine tools. It also uses high-frequency discharge to corrode workpieces and causes high-frequency disturbances to intelligent error correction controllers. Interference is generally referred to as signal-independent, unpredictable and harmful electrical transients that occur during signal input, transmission, and output. The interference source is generally power interference. Due to the wide coverage of the power grid, there are multiple devices sharing a power grid, especially changes within the power grid, power switch operation, lightning surge, start-stop of large-scale power equipment, and harmonics caused by AC/DC transmission devices. Short-circuit transients in the power grid, etc., are transmitted to the primary side of the power supply through the transmission lines, causing temporary changes in voltage, resulting in grid voltage fluctuations. In addition, power lines can also generate noise and fast transient bursts during transmission, polluting the grid. It may also be that radiated electromagnetic or electric fields are ubiquitous in nature. In addition to the electric field, the electric spark piercing machine in operation receives a magnetic field. In the course of operation of the EDM machine, due to the harsh environment of the work environment, it will inevitably be interfered by the electromagnetic interference digital signal and the analog signal EDM CNC punching machine during the work process, due to the greater number of devices involved in the device , Both AC380V, AC220V AC signal, but also DV24V, DC5V various low-voltage DC signals. Cables used to transmit signals sometimes cause malfunctions due to analog signal output devices or interference generated by servo drivers or inverters, affecting the normal operation of the device; used to transfer I/O input/output The frequency of the signal is interfered with by the clock frequency and harmonics, as well as the improper alignment of the circuit, so that the digital signal line and the analog signal line will inevitably be interfered by external interference signals, and the various signal lines will also be coupled to each other through lines. Such as interference.

Because the interference of various interference sources will cause some transient phenomena, the data in the numerical control system will change during the transmission process, increase the error, cause the abnormal situation of the local device or the entire system, and cause the failure.

Die Casting is a Metal Casting process that is characterized by forcing molten metal under high pressure into a mold cavity. The mold cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mold during the process. Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminum, magnesium, lead, pewter and tin-based alloys. Depending on the type of metal being cast, a hot- or cold-chamber machine is used.

The casting equipment and the metal dies represent large capital costs and this tends to limit the process to high-volume production. Manufacture of parts using die casting is relatively simple, involving only four main steps, which keeps the incremental cost per item low. It is especially suited for a large quantity of small- to medium-sized castings, which is why die casting produces more castings than any other casting process. Die castings are characterized by a very good surface finish (by casting standards) and dimensional consistency.

The main die casting alloys are: zinc, aluminum, magnesium, copper, lead, and tin; although uncommon, ferrous die casting is also possible. Specific die casting alloys include: Zamark; zinc aluminum; aluminum to, e.g. The Aluminum Association (AA) standards: AA 380, AA 384, AA 386, AA 390; and AZ91D magnesium. The following is a summary of the advantages of each alloy:

Zinc: the easiest metal to cast; high ductility; high impact strength; easily plated; economical for small parts; promotes long die life.
