Accredited International Certification & Micron-Level Metrology
After rough turning, finish turning, and chrome finish operations, journal bearing seats and body diameters are tested using precision micrometers.
Mitutoyo Laser Micrometer & Zeiss CMM
±0.002 mm (2 microns) on journal seats
High-speed printing cylinders are dynamically balanced on electronic balancing machines to eliminate operational vibration and verify runout.
Schenck Dynamic Balancing Unit
ISO 1940 Grade G1.0 (Runout < 0.01 mm)
Mirror-polished surfaces are scanned with laser profilometers to establish surface roughness (Ra) graphical quality reports.
Mitutoyo Surftest SJ-411 Profilometer
Surface roughness: Ra < 0.05 µm
Micron-level verification of cylinder geometry, diameters, and bearing tolerances through precision CNC machining and measurement.
Electronic dynamic balancing, vibration control, and runout verification for reliable operation at high rotational speeds.
Precision profilometer measurement and reporting of surface roughness after the finish-grinding process.
By keeping axial and radial runout in cylinders under control, we prevent the risk of printing defects and ensure visual clarity.
