Frequently Asked Questions

A pin gauge is a precision cylindrical tool used to measure the inner diameter of holes, verify hole sizes, and check slot widths in manufacturing and quality control. They are essential for go/no-go inspection in machining and assembly.

CEGA pin gauges are manufactured to ±0.001mm accuracy (Class ZZ equivalent), with some ceramic models offering ±0.0005mm precision. Each gauge is individually inspected and comes with a calibration certificate.

CEGA offers pin gauges in three main materials: hardened tool steel (HRC 60-62) for general use, ceramic for non-magnetic and corrosion-resistant applications, and tungsten carbide for extreme wear resistance.

Select a pin gauge size that matches the nominal hole diameter you need to inspect. For go/no-go testing, use the go gauge at the lower tolerance limit and the no-go gauge at the upper limit. CEGA offers gauges from 0.10mm to 20.00mm in 0.01mm increments.

Yes, every CEGA pin gauge and gauge set includes an individual calibration certificate traceable to international standards. Sets include a master list of all gauge sizes and their actual measured values.

A go gauge is sized to the minimum acceptable dimension and should enter the hole if it is within tolerance. A no-go gauge is sized to the maximum acceptable dimension and should NOT enter the hole. If the go gauge enters and the no-go gauge does not, the part passes inspection.

Store pin gauges in their original fitted cases, away from moisture and corrosive environments. Clean with a soft cloth and light oil after each use. Avoid dropping or gauging rough surfaces. Annual recalibration is recommended for critical applications.

Yes, CEGA manufactures custom pin gauges to your exact specifications, including non-standard sizes, special lengths, and custom marking. Contact our sales team with your requirements for a quote within 24 hours.

Gauge blocks are precision measuring standards used to calibrate measuring instruments, set up machine tools, and verify dimensional accuracy. They are wrung together to create exact lengths for inspection and calibration in manufacturing and metrology labs.

CEGA gauge blocks are available in Grade 0 (±0.12μm) for calibration labs, Grade 1 (±0.20μm) for inspection rooms, and Grade 2 (±0.45μm) for general workshop use. Each block is individually inspected and comes with a calibration certificate.

CEGA offers gauge blocks in two main materials: hardened steel for general workshop use and ceramic for non-magnetic, corrosion-resistant applications requiring exceptional dimensional stability. Both are lapped to ultra-flat surfaces for reliable wringing.

Clean both surfaces thoroughly, then slide one block across the other with light pressure while maintaining full contact. The molecular attraction between ultra-flat surfaces creates a strong bond. Always clean blocks before and after wringing to maintain accuracy.

Store gauge blocks in their original fitted cases, away from moisture and temperature extremes. Clean with a soft cloth and light oil after each use. Never drop or scratch the measuring surfaces. Annual recalibration is recommended for critical applications.
