Special Applications

Slot Measurement

How to Understand

To design anvil head for Slot measurement, the following information is required:
ML - Length of Slot to be measured
W - Width of Slot
DC - Depth of clearance for Cover plate
EW - Smallest width through which the given head has to pass
L - Length at which measurement is req. (Add extension if required)
HC - Head clearance (If there is no Bottom or Head clearance, extra special Anvil Design can be provided)

Taper Measurement

How to Understand

To design the Anvil head for Taper measurement, the following information is required:
ED - Entry diameter of the component.
L - Length of the component
DD - Datum point diameter
MD - Minor diameter of the component
LD - Length at datum point


RECOMMENDATION - Three point system is recommended. Two point system also avaibble as an option.
See Table - For standard measuring lengths
See Table - More than one extension can be used. For extension lengths available
NOTE:- - Ball contact is recommended for datum measurement (DD).

Ball Screw Measurement

How to Understand

To design the Anvil head forfor Ball screw thresd measurement, the following information is required:
MD1 - Major diameter of the thread
MD2 - Minor diameter of the thread (can be gauged by using standard three point heads)
P - Pitch of thread
DT - Depth of thread
BD - Ball diameter


RECOMMENDATION - Three point system is recommended. Two point system also avaibble as an option.
See Table - For standard measuring lengths
See Table - More than one extension can be used. For extension lengths available
See Table - For sandard Avil head Ranges available

Deep Hole Measurement

How to Understand

To design the Anvil head for Deep Hole measurement, the following information is required:
ED - Smallest dia through which the given head has to pass
L - Length at which measurement is req. (Add extension if required)

The purpose of the Bush is to protect the Anvils when sliding through deep holes. For normal applications this bush is not required. When measuring deep holes user should ensure the alignment of Gauge axis and Bore axis. For measuring deep holes Spherical contact points are preferred because they allow certain amount of deviation in Gauge axis without affecting accuracy.


RECOMMENDATION - Three point system is recommended. Two point system also avaibble as an option.
See Table - For standard measuring lengths
See Table - More than one extension can be used. For extension lengths available

O Ring Groove Measurement

How to Understand

To design the Anvil head for O Ring Groove measurement, the following information is required:
MD - Dia to be measured
ED - mallest dia through which the given head has to pass
O - Width of O ring groove
L - Length at which measurement is req.(Add extension if required)
DC - Depth of clearance for Cover plate
HC - Dia of bottom clearance (If there is no Bottom or Head clearance, extra special Anvil Design can be provided)


RECOMMENDATION - Three point system is recommended. Two point system also avaibble as an option.
See Table - For standard measuring lengths
See Table - More than one extension can be used. For extension lengths available

Spherical Diameter Measurement

How to Understand

To design the Anvil head for Spherical Diameter measurement, the following information is required:
SD - Spherical diameter to be measured
ED - Smallest dia through which the given head has to pass
L - Length at which measurement is req. (Add extension if required)
HC - Dia of bottom clearance (If there is no Bottom or Head clearance, extra special Anvil Design can be provided)


RECOMMENDATION - Three point system is recommended. Two point system also avaibble as an option.
