The appearance size is guaranteed, and the loose defects such as dendritic crystals, carbides, shrinkage holes, and bubbles in the steel are extended and elongated along the processing to form a streamlined line, which has a great impact on the final quenching deformation, cracking, and brittle cracking and failure tendency during use.

Unmanned vending machine shipping gearbox ribbon holder is generally fixed by the clip, loosen the card can take down the cover of the ribbon frame, you can see the ribbon core inside, take out the old ribbon core, pay attention to remember the position of the gear, tablet, and then put the new ribbon core in, according to the position of the old core through the gear and tablet, cover the cover, turn the knob to tighten the ribbon core, and then install it back to the printer.

Many advantages such as small workpiece heating and deformation make mold enterprises pay more and more attention to high-speed processing. The combination of processing technology and green product technology will be considered when purchasing equipment in the scope of radiation and medium selection of electrical processing machine tools will be safe, and when the ribbon product is used to the end of life, it is necessary to replace the ribbon core, and the used ribbon core in the ribbon box is replaced with a new one, which is equivalent to a brand new ribbon box.
