According to manual machinists, CNC guys press cycle start… then go take a nap. CNC machinists might argue otherwise — but this meme had both camps laughing. Also inside: the checkerboard bore that sparked 900+ comments and real CNC jobs from shops that don’t suck.

Top Comments Include:

  • “Accurate representation of me being home away from work still hearing the machines run In my head😂”.

  • “That’s wrong. You push a button every once in awhile”

  • “my beds a little further from the machine than that.”

  • “Yes! Holding that .0005 tolerance on those Navy nuclear pump impellers with a 28 year old CNC is just so easy any monkey can do it.”

  • “He's having a nightmare about the end mill slamming into the vise at 50 inches a second.”

  • “What they actually do…”

🧰 A Better Way to Handle CNC Chips. Dakota Metal Solutions makes a CNC Chip Hopper designed specifically for machine shops. It features a built-in trough and valve system that drains coolant before dumping the chips, helping keep scrap bins cleaner and coolant out of the mess. Heavy-duty steel. Self-dumping. Forklift friendly. On casters so it can move around the shop.

How is this possible?

This one absolutely broke the MACHINIST group.
A checkered finish inside a bored aluminum casting sparked 900+ comments and just about every theory in the shop. The crowd’s main verdict: harmonics/chatter from a thin wall and a finicky setup — with fixes ranging from backing off RPM to the classic rubber bands / modeling clay trick. Of course, the funniest consensus was even stronger: call it a proprietary performance finish and charge extra.
