Tight Tolerance Stack-Up: How We Hold ±0.005 mm Across One Plant

Any shop can hold ±0.01 mm on one feature. The hard part is holding the relationship between features — position, profile, runout — consistently, across every machine in a large facility.

One thermal environment, one standard

• Climate-controlled metrology so the CMM and the shop agree on temperature.
• Calibrated gauges on every cell, on a single calibration schedule.
• Shared datums and setup sheets so part 10,000 matches part 1.

Stack-up is a design conversation

Before we cut, we review your tolerance stack-up. Sometimes a tighter individual tolerance is unnecessary and a looser one elsewhere is the real constraint. We flag that early, because cutting scrap starts on the drawing, not the shop floor.
