It really depends on the workflow and scale of operation the cutting tool manufacturer. Some focus mostly on small batches of very specialized tools, and some focus on producing huge volumes of standardized cutting tools. And anything in between of course.

Whatever the grinding machine that is used, there is always a necessary setup step before the production run. The setup involves installing some equipment on the cnc machine, heating up to operation temperature, calibration, dry run to check for possible collisions and grinding a few pieces and check that they are within specs.

The name of the game is then, given typical customer order or target market, to find the right balance between the utilisation of the different machines, human intervention and automation while optimizing for cost and cutting tool quality.

In the video, it look like it is a pretty small manufacturer doing small specialized batches. In this case most of the time is spent doing machine setup and quality control, and the drill value doesn't justify the investment into a more complex or automated system.
