For general taps processed by non-standard parts processed by hardware parts, use a half-diameter electrode to remove broken taps. Large tap, the broken screw is processed with a hexagonal electrode, and then taken out with an Allen key. Other broken tools and knives shall be processed with electrodes of suitable shape and size.
The processing sequence of non-standard parts: put a metal plate in the plastic container - fix the parts to be processed and the processing head - (the magnetic base should not be put into the water) - the brass electrode is installed in the chuck to tighten, The diameter of the electrode is half of the nominal diameter of the tap—connect the cable, and connect the wire clamp to the processed part—find the position of the electrode and the tap, the distance is 1-2 mm, adjust the stroke indication position—into the container Add working fluid, at least 10mm above the surface of the part - turn on the main power switch - select the machining current - press the start key to start processing - when the machining is over (reach the set depth), the machining will be stopped automatically, and the electrode will be raised by manual operation.
Injury and protective measures of non-standard parts processing chips for hardware parts processing. The various steel parts processed on the lathe have good toughness, and the chips generated during turning are rich in plastic curling and have sharp edges. When cutting steel parts at high speed, red-hot and long chips will be formed, which are very easy to hurt people. At the same time, they are often wrapped around the workpiece, turning tools and tool holders. Therefore, iron hooks should be used to clean or break them in time during work. If necessary When it is necessary to stop and clear it, it is absolutely not allowed to clear it or pull it off by hand.
In order to prevent chip damage, hardware parts processing often take measures to break chips, control the flow of chips and add various protective baffles. The measure of chip breaking is to grind chip breaker grooves or steps on the turning tool; use appropriate chip breakers and mechanical clamping tools.
