CNC Heat Sink Finning Machine SQ-150MAX

The SQ-150MAX achieves 0.005mm positional accuracy using Taiwan TBI ball screws, HIWIN linear guides, and Germany IBC bearings. This level of precision allows consistent production of fins as thin as 0.05mm — critical for high-performance heat sinks where fin uniformity directly affects thermal conductivity and airflow distribution.

Process both copper and aluminum billets with fin heights up to 35mm and 70mm respectively. Adjustable pitch from 0.1mm to 10mm and blade lengths up to 500mm accommodate everything from dense micro-fin arrays for power electronics to wider-spaced configurations for natural convection cooling, all on a single machine.

The 500×300mm vacuum suction cup system secures workpieces without mechanical clamps, reducing setup time between batches and eliminating clamping marks on finished parts. This is particularly valuable when producing heat sinks with tight cosmetic and dimensional tolerances for end-use applications.

The Taiwan Baoyuan CNC controller manages coordinated X/Z axis motion with rapid traverse rates of 15m/min and 25m/min. Schneider, Siemens, and LS electrical components ensure reliable operation across extended production shifts, while the handheld pendant enables precise manual positioning during tool setup and first-article inspection.

A fully enclosed work area contains chips and coolant, with a clear viewing panel for real-time process observation. The integrated status light tower, emergency stop system, and centralized lubrication via Golden Armor pump and automated oil distribution keep the machine running safely with minimal operator intervention.
