Try high-frequency quenching and grinding the surface.

Not long ago, the tool bar box of EDM finally had time for high-frequency heat treatment, unfortunately, the high-frequency machine power of 15KVA was too weak for 2.5kg alloy steel, and it took about 12 minutes to heat to a dark red color, and then dipped into the waste hydraulic oil to quenched. The hardness can only be increased by a very limited amount, and I will continue to try the appropriate process in the future.

The surface is then polished using a grinder, and finally the V-groove is ground.

我完美地完成了大部分工作。在最后的过程中，我没有遵守安全规则，导致了严重的撞车事件。我应该关闭回转并调整位置。或者移至安全区域并调整回转高度。这将提醒我在未来的操作中安全的重要性。

Woah! Somebody has worked on their camera skills and has added making videos to their Toolbox! Well done!

Glad you didn't voice over though!
