There are several kinds of wire cutting protective covers, such as armor protection cover, steel plate protective cover, etc. the basic component is that each fold is equipped with a supporting and stable effect, and the skeleton can be closely connected with the external folding data through different processing methods.
The appearance of the protective cover is lubricating and beautiful, which adds infinite color to the whole modeling of the machine tool. Therefore, it not only provides practical maintenance for your machine tool, but also adds more visual beauty to the machine tool, so that the whole value of the machine tool has been improved. Steel telescopic guideway guard is a traditional protection method for machine tools. In this field, the steel telescopic guide rail protective cover is widely used, which has a useful protective effect on preventing the entry of chips and other sharp things. After certain structural measures and appropriate scraping plate, the coolant can also be effectively lowered.
The protective cover can be used to protect the lead screw, smooth screw, column, spindle and other circular rotating cylinder. Can be used horizontally or vertically. In horizontal application, it is recommended to use plastic or aluminum support ring, and there is a certain uniform interval between the inner cavity of the shield and the screw rod, so as to prolong the service life. When the drawing length is large, the metal ring can be added to each compromise to improve the safety and stability of the shield.
Processing conditions of wire cutting
In order to avoid the waste of some personnel and funds, it is necessary for us to have the following conditions for WEDM to operate normally
1. It is necessary to adhere to a certain gap between the molybdenum wire and the machined surface of the workpiece. The width of the gap is determined by the working voltage, processing capacity and other processing conditions.
2. It is necessary to select the pulse power supply to eliminate the ionization of the interstitial medium within the pulse interval, so that the next pulse can breakdown and discharge between the two poles.
3. WEDM machining, it is necessary to have a certain insulation function in the liquid medium, such as kerosene, saponified oil, deionized water, etc., between the molybdenum wire and the surface of the workpiece to be processed adhere to a certain gap, if the gap is too large, the voltage between the electrodes can not break through the electrode dielectric, then the spark discharge can not occur; if the gap is too small, it is easy to form a short circuit connection, also can not be generated Discharge of WEDM.
