Wouldn't like to tie myself to a figure on this particular type of machine, but a lot! I work in aerospace automation so looking after CNC machines is part of my daily job, and also B3 are pretty open about what they use. Here's a video of theirs, you can see the difference in how much simpler the operation is: https://www.youtube.com/watch?v=W-by0iATB8c
Yeah definitely you could use this to produce bats if you really wanted to, wouldn't want to come across like I'm just taking the mickey because of the daft bat it's producing in the video, but other types of machine are available that are less complicated (i.e. less expensive and more reliable) and I would expect more accurate. It's not exactly quick either by the looks of things!
The B3 does look far simpler than this machine i have never stated it wasnt. AS for the costings and working of the machine, Im going to play devils advocate, do you know the costings and the ins and outs of how it runs? There is no way you can tell from that video if it would be more accurate or not. It may well be less accurate but whats to say it wont be??
By the looks to it is working horizontally on the video while the B3 one is going vertically so of course would be different.
Using the harder timber( look like some form of hardwood in the video) may cause it to be slower,
Whats to say it couldn't run at a similar speed to the B3 one, plus the added bonus of 8 at a time
I just think there are so many variables in the video so making assessments could be risky without seeing it under same conditions
Fully respect your profession and you would know more than most about CNC
