1. Where chips come from
? Bit-to-screw friction: repeated contact and rotation scrapes metal from both surfaces.
? Thread deformation: material under high stress extrudes fine chips.

Left inside the product, these particles can short circuit boards, jam mechanisms, or shorten service life.

2. Proven removal methods

a) Vacuum pick-up module (suction screw-driver)
– A vacuum line inside the bit shank pulls chips away the instant they are created.
– Optional side ports in the bit nose add extra suction paths for stubborn debris.

b) Parameter optimisation
– Reduce driving pressure and RPM to the lowest values that still achieve target torque.
– Run DOE trials to balance joint strength and chip generation.

c) Timely bit replacement
– A worn (blunt) bit increases friction and chip volume.
– Establish change intervals based on cycle count or elapsed hours.

3. Role of the driver gun
Advanced drivers with multi-step programmes deliver controlled torque and speed curves, working in tandem with the suction module and optimised parameters to minimise debris while keeping takt time short.

Combine these measures—vacuum extraction, parameter tuning, scheduled bit changes, and intelligent drivers—to keep production fast and products clean.
