Measuring pins and measuring balls
are used for size inspection of gear profiles
Measuring pins can only be used to carry out size inspections on spur gears. When using pins it must be taken into consideration that where there is a high degree of waviness on the teeth, the pins will only sit on the highest points.
|Hard metal||±0,001 mm||Workpieces accurate|
|Hard metal||±0,0005 mm||Gage inspection|
|Hard metal||±0,0003 mm||Master and Artefacts|
Measuring tips are always made of carbide. They are used when diameters smaller than 1.5 mm are required.
|With thread M2||Smaller 0,75 mm|
|With thread M2,5 (Standard)||Smaller 0,75 mm|
|With thread M3||Smaller 0,75 mm|
Measuring balls, measuring ball inserts and measuring pin inserts are always manufactured from carbide (carbide 1500HV) as steel would wear too much.
|Measuring balls soldered on shaft with thread M2,5 without SW||1 to 7 mm|
|Measuring balls soldered on shaft,|
with thread M4 with SW
|5 to 12 mm|
|Balls with internal thread M4||10 to 25 mm|
Measuring balls and pins are subject to wear during use, which has to be monitored in line with the monitoring of inspection equipment schedule. FRENCO offers these monitoring services.
