Why Does This CNC Machine Have Two Spindles?

A US data center cooling manufacturer was failing 8% of leak tests on stainless steel manifolds.

Then they ditched rivet nut welding and switched to 1-setup thermal friction drilling.

Here is what happened next: ✔ Leak test failures dropped from 8% to ZERO ✔ Process cut from 4 machines to 1 automated cycle ✔ Tooling costs slashed by 65% ✔ Production output boosted by +300%

Watch how a single BT40 spindle extrudes thick threads directly out of thin-walled 304 SS tube walls—no welding, no deformation, perfect O-ring seals every time.

Are you still using rivet nuts or multi-station setups for liquid cooling manifolds?

Automatic Tool Changes on a 3-Meter Steel Workpiece

How do you drill 1mm holes into inclined hard alloy without snapping your drill bits? We just cut cycle time from 8 minutes to 3 minutes—with ZERO tool breakage. ⚡

Here is how we did it: ✔ Dual-spindle setup: Pilot mill flattens the slope first, then the deep drill goes straight in. ✔ High-speed precision: 60,000 RPM spindle eliminates deflection. ✔ 10:1 Depth-to-diameter ratio handled easily. ✔ Clean, burr-free finish compared to slow EDM.

What's the hardest material you've had to micro-drill on an angle? Let's discuss below!
