Can Allied Technologies International hold tolerances on parts under 3 mm in diameter?

Yes. The shop runs bar-fed machining platforms with guide bushings sized for small stock, so diameters from about 0.5 mm upward are routine, including cross-holes, slots, and threads cut in one cycle. Tolerances near 0.0002 in. hold through a complete bar run.

What limits how small a feature can get on a Swiss machine?

Live tooling on 0.5 mm micro end mills cuts slots near 0.3 mm wide, and thread whirling handles 0-80 and M1.2 threads. The binding constraint is usually depth-to-diameter ratio or material, not the machine itself. A shallow slot in brass is routine; the same slot in titanium is not.

Why does Swiss turning hold tighter tolerances than a turret lathe?

The guide bushing supports the bar within microns of the cutting edge, so the tool never fights an unsupported length. Less deflection and less thermal drift shrink the total tolerance band on a 3 mm diameter. That difference often reaches 0.0005 in.

Is Swiss machining worth it for low volumes?

Usually not, and it is worth saying plainly. Setup, bar preparation, and tooling carry fixed costs that a small batch cannot absorb, so CNC Swiss machining pays off as quantities climb into the thousands. Below that, conventional turning ships parts cheaper.

What bar stock does a guide bushing need?

Centerless-ground bar is the safe choice, since cold-drawn stock varies by several thousandths and forces the bushing setting loose. Accuracy and finish both suffer, and bent or contaminated bars damage a bushing far faster than they damage a chuck.

Why Is Swiss Machining Ideal for Small, Complex Precision Parts?

Small parts fail for reasons that never show up on a drawing. A 1.5 mm bone screw with a cannulation bore leaves little material for the tool to push against. Deflection wins, and the tolerance is gone. CNC Swiss machining holds the workpiece at a guide bushing instead of cantilevering it in a chuck. The […]
